Vote! How to Detect the Social Sites Your Visitors Use
One of the great things about the web is the relative ease with which one can set up a new service. In social bookmarking alone with have Del.icio.us, Digg, Facebook, Fark, Mister-Wong, Newsvine, Reddit, Technorati, Slashdot, and StumbleUpon, to name a few. That’s great for competition, and that’s great for users, but it’s not so good for bloggers and content creators.
What are you to do if you want readers to promote your content? Kevin Rose, of Digg, put it succinctly: “Encourage your visitors to submit their favorite stories directly to Digg [with a Digg badge].” Not everyone uses Digg. You have to decide on which bookmarking site, if any, to dedicate your precious screen real-estate. It’s a hard choice. If you choose poorly your reader won’t vote—it’s not a single click coupled and out-of-sight means out-of-mind—and your content losses its chance to make it big. You have to choose your horse wisely.
On the other hand, if you take the bird-shot approach, it overloads your reader with branded badge after branded badge. It turns your page into the village bicycle. Not pretty.
Nobody seems to have solved the problem yet. Lifehacker, for instance, uses a single Digg badge on their long articles, but they also list a couple of the top social bookmarking sites on every post. Wired takes the total shotgun approach, and they own Reddit.
There has to be a better way.
If you could detect which social bookmarking sites your reader uses, on a per-reader basis, you could display only the badges they care about. But you can’t know that because the browser secures the user’s history, right?
Wrong.
I know that you visit: . It’s a bit scary, I know. I’ll come back to how I know in a second. We can use this information to only display one or two badges that we know the reader uses. It solves the which-badges-to-display problem.
SocialHistory.js
Today I’m releasing SocialHistory.js, code which enables you to detect which social bookmarking sites your visitors use. Here’s an example of how to use it:
<script src="http://aza.googlecode.com/svn/trunk/SocialHistory/SocialHistory.js"></script>
<script>
user = SocialHistory();
var visitsDigg = user.doesVisit("Digg");
var visitsSlashdot = user.doesVisit("Slashdot");
var listOfVisitedSites = user.visitedSites();
</script>
SocialHistory.js cannot enable you to see all of the user’s history. It has to ask, 20-questions style, if the user has been to a particular URL: It’s hit or miss. SocialHistory.js has a big list of the most popular social bookmarking sites which it checks against. To see the list of sites, you can do:
user.checkedSites()
SocialHistory.js can also check other sites. For instance, if you want to see if your reader has visited any of the blogs I write, you’d do the following:
moreSites =
{
"Aza": ["http://humanized.com/weblog", "http://azarask.in/blog"]
};
user = SocialHistory( moreSites );
alert( user.doesVisit("Aza") );
How Does It Work?
How does SocialHistory.js know? By using a cute information leak introduced by CSS. The browser colors visited links differently than non-visited links. All you have to do is load up a whole bunch of URLs for the most popular social bookmarking sites in an iframe and see which of those links are purple and which are blue. It’s not perfect (which, from a privacy perspective, is at least a little comforting) but it does get you 80% of the way there. The best/worst part is that this information leak probably won’t be plugged because it’s a fundamental feature of the browser.
Vote For Me, Where You Care
Enjoy cleaner, more aware pages. Gone are the medieval days of badge spamming!
P.S. Yes, I do feel a bit dirty for using this information leak. At least I’m using it for a modicum of good. My cleaner half raises the cup to hoping that Dave Baron can stop the leak in Firefox by vanquishing bug 147777.

It’s an excellent idea, I had thought for a second that it was less useful than it could be because it doesn’t detect that I’ve used my delicious pluggin.
However, there isn’t much point in showing me the icon when I use a pluggin – so it doesn’t impact the usefulness.

“I know that you use: and undefined”
I have to say I’m not particularly impressed. :-(
I do use Facebook and Last.FM, so not sure why it didn’t pick that up.
Kroc Camen
Copy and Paste has existed on computers longer than I’ve been alive. People should learn to use it.
I really hate these links and take every opportunity to edit them out of pages. I don’t even want their traffic; Digg has become the cesspool of the Internet.
Aza Raskin
@Gijs: Could you let me know what browser and OS you are using? I’ve testing using Firefox 3/Safari on OS X, and IE 7/8 on XP. Also, I realize that I forgot to add Last.fm to the list of sites checked. Fixed that ;)
[ICR]
I’ve seen this approach before. It’s quite clever, though not without it’s drawbacks. For instance, what do you show if they’ve never been to a social bookmarking site? How do you get people aware and interested in these services. It’s also not 100% reliable.
I think a nice compromise is to have something like the bookmarks they use actually shown, and then hide the rest away in a drop down menu of some form so that people can still get to them should the check fail.
Neil
In supported browsers, you could probably do the same sort of thing in CSS.
.social { display: none; }
:visited + .social { display: inline; }
…
T
Or just:
.social a { display: none }
.social a:visited { display: inline }
grabur
This solution is more elegant. Unless like me, you abandon the author’s styles half the time.
Kevin
>Wired takes the total shotgun approach, and the own Reddit.
should probably read “and they *own* Reddit”
Wladimir Palant
Yes, and the above can even be made to work in IE6:
<style>
.social {display: none}
.social:visited {display: block}
</style>
<a class=”social” href=”http://digg.com/”><script src=”http://digg.com/tools/diggthis.js” type=”text/javascript”></script></a>
Kevin
Also, this is useful only if you don’t use something like Google Analytics. I can tell you that 95% of social news visitors to my site use Reddit and Stumble Upon — I should probably add vote buttons for those sites.
Ehsan Akhgari
There is one bug in the code that I observed.
“htts://del.icio.us/” should probably be “https://del.icio.us/”, right?
Neil
Sorry, I didn’t realise that your blog would eat my HTML…
<a href=”http://slashdot.org/”></a><span id=”slashdot” class=”social”>…</span>
Geoff Pado
Doesn’t seem to work on iPhone. Cool idea, though.
Chris
It’s a great idea. One improvement that you might be able to make is to tell if the user goes to any page on the site, rather than simply the front page. For example, I never go to the front page of last.fm; I go straight to my user page. When I used reddit (I gave it up because I was too addicted) I would often go to programming.reddit.com instead of the front page.

A useful trick, thanks for wrapping it up a easy to use library.
@Kevin: Google Analytics won’t give an immediate response to the person viewing the page. This isn’t a tool for you to see what sites your visitors use (though you could use it that way with a call-back of some sort.)
@ICR: Use a count, if it is 1 or less then display some default sites. Or, use this library to prioritise the list (pretty much what you said in your second paragraph.)

Actually, I use several of them, and I’m currently logged into those that I use through their Firefox plugins/toolbars. Using Firefox 2 on WinXP.
Pete
Cool idea!
Any neat package that could use it for gathering statistics? E.g, if I knew 40% of my visitors used digg, I might look at marketing to it more, or if I noticed a large portion of my visitors used an obscure social news site I’d certainly spend some time to learn more about it and market to it.

“and Ma.gnolia”
If I have a Ma.gnolia account I have forgotten. I have many others though… but I rarely access them through my browser. E.g. del.icio.us.

It’s “Menéame” not “Menaeme”. Cool, nevertheless.

Brilliant work. I only fear the more malicious uses this could be put to.
Jerry Bell
Two comments:
First, pretty neat. Apparently this has been around for a little while, and I would like to see the maintainer of “bookmark me” for wordpress integrate that functionality.
Second, I have had some visitors rail against any kind of javascript pretty hard. So, it could cause some amount of backlash, but it’s probably worth it.
j dizzle
Would it make more sense to use https://login.facebook.com/login.php for the facebook site? With the current setup you could be hit with both false negatives and false positives. If you just browsed to http://facebook.com but don’t have an account, you would show up as being a user. Alternatively if you have a clear history, then just click on a link from an e-mail to a facebook page and login, you would never hit any of the URL’s you have listed. The login is the action URL for all logins, and would seem to make the most sense in determining who is a member and who isn’t.
Dobbie Johnson
I have to admit I am not that impressed either. People in those places should be using privacy services like Ultimate Anonymity ( http://www.Ultimate-Anonymity.com ) or something like it to remain private.
DJ
kL
In anything-but-IE6 you can do it without JS:
.social a + * {display:none;}
.social a:visited + * {display:inline;}
and have link to the site immediately before div/span with a button.
Bertil
You do not seem to pick up Facebook.
Isn’t there a significant privacy risk? As long as you exclude the “Adult” networks, I can’t really imagine something concerning, but you never know. . .
I’ve seen (and I like) to have a collapsible button with all the websites (“More. . .”).
I’ve never seen (and I would dream to, and I had to poorly code it myself) a “Send by e-mail” button: not one that sends you to a crappy, useless webform, but a proper “mailto:” link or an intelligent webmail, based on the same hack (ever been to mail.google.com, mail.yahoo.com, etc. recently?)
E-mail it is still the most extensive network.
Finally, if you want to gain traction towards the less inclined: an easy embeddable link (that relies on the .js on your own server)? At least, it would be up-to date.
Justin
I know that you use: none of the sites I know about.
Hmm. Considering I was directed here from reddit and use several of the other sites you gave examples for, I’d say it could use some work.

It’s because of tools like you we use noscript. Good luck finding out what ones I visit.
Certainly putting azarask.ini/* in my adblock and noscript settings for the estates I manage.
Amy Cham
Clever! One could add in some default links to the sites most appropriate to your audience in the event of an empty or very small set, and something to sniff out the referrer to see if they’ve come from one of the sites as a backup to the CSS test if you want to get fancy…won’t get everything, but it’s a very nice improvement over a big list of links to sites you may have never even heard of!

Alternatively, you could just not have a thick layer of what amounts to ads on every single one of your blog posts, and maybe trust your readers to spread anything you write that’s worth spreading instead of begging them to spam every one of your posts everywhere regardless of what it says. I find that INCREDIBLY irritating and fail to see why every single news aggregator needs to contain every single blog post ever written.
But maybe that’s just me.
David Owens
I’m not sure why you need the + * part in this:
.social a + * {display:none;}
.social a:visited + * {display:inline;}
I would have gone for:
a.social {display:none;}
a.social:visited {display:inline;}
and used the social class in the a element.
Peter T - Webshop
Just added this to my Del.icio.us account, great and extremely useful post, thank you. The goal is not simply gathering information for the sake of it or even for promoting your site. The information can be used to gather information regarding users so that you can better serve them and tailor your apps to simply their online experience and even improve and optimize the user experience. Many people are often weary of sites creating proflies on them however this information could be used to help the user. You as a free thinking, independent individual can utilize your free will to decide whether you’ll allow this or not, there are tools out there that can help keep you invisible as you surf the net but you won’t reap the rewards of being recognized and in an interesting place in the human psyche most people like to go, “where everybody knows your name”.

Coloring is a fundamental feature. Reporting the color correctly to your script is not, and dbaron has been thinking for a while about how to change things so this will stop working.

Ben Bucksch
Don’t use this. The fact that you can do that is a bug. See
Mozilla bug 147777 mentioned above. Don’t complain when it no longer works.
The right solution is for the surfer to install an extension for the bookmarking site they use, and the website to have no badges at all.

Jon
Cool idea, but you can just use the Siphs.com plugin to handle this problem.
Justin Dolske
One interesting observation is that the privacy implications (and general usefulness) of this method diminish somewhat with Firefox 3… History is kept for a default of 90 days now, which means that this will catch site visits that didn’t necessarily happen recently. I know a couple of the sites this listed for me are ones I can’t remember having visited in a long time.
Aza Raskin
@Justin: True. On the flip side, I used to clear my history, cookies, and all my private data fairly regularly. However, now that there is the Awesome Bar in Firefox 3, I never clear my history. The history that the Awesome Bar exposes is, well, too awesomely useful.
@Chris Cunningham: That’s for pointing me to the bug. It’s good news that the Firefox team is trying to solve the problem. It’s a hard one.
@j dizzle: Yep. My original thought was to use favicon URLs, and login URLs. The former didn’t show up as :visited (although, I suppose I could do a timing attack on image load speeds). The latter is sometimes hard to find with all of these new Ajaxy Web 2.0 in-page logins.
@anon: As a couple of people mentioned in comments, there are pure CSS ways of hiding non-visited sites. It’s a bit more limited, but works. Also, this logic isn’t mission critical, so consider it as an upgrade that can gracefully degrade with Javascript isn’t enabled (or has been kill with NoScript).

“I know that you visit: Reddit, Facebook, Del.icio.us, Slashdot, and Menaeme. It’s a bit scary, I know.”
Er, it’s a bit wrong. I’ve never heard of “Menaeme” (??). I logged into Facebook once, almost a year ago, and I haven’t been to del.icio.us in almost as long.
I think we can file this under “neat technical trick, but with so many problems it’s not really feasible for telling what ’social’ websites the user actually frequents”.
Laura
Yes, I am commenting just to be one of those annoying people that say you got it wrong!
Facebook and mixx showed up for me, I am on facebook but I’m also on delcious (none of the others) and I’ve never heard of mixx. Very clever idea though.
Aza Raskin
@ Laura, et el. Probably what “getting it wrong” means is that sometime way in the past you visted the site and then forgot about it. It’s one of the inevitable problems with a system that can query only one bit of information: have you every gone to a site or not? Also, as a couple folks have pointed out, adding more URLs to the list of checked URLs would help increase the hit-ratio.
Bob
Hey there. Also one of the annoying ones. I have been to or used Facebook, Digg, StumbleUpon, Del.icio.us, and Diigo, but it says you don’t see me using any of those sites. Currently running the Flock 1.2 beta.
Stephan Schmidt
Pure genius.
coldclimate
Massively uninformed comment here, but couldn’t this be modified fairly easily to allow A Not Nice Person to detect which bank’s website you’d visited, and serve you a pop-under or other mechanism based on that info?
Matt
Congrats for doing your part to destroy privacy on the web.
Dimension
Interesting idea, but the script doesn’t show all the sites I visited.
I think I know why: I cleared my history and visited “digg.com”. I didn’t show up in the list.
Then I visited “www.digg.com” and it showed up.
Maybe you could check URL’s with and without www in the script to get all visits…
A very useful trick, thanks!
Beejamin
Got to love all the people saying – this sucks – I hate all those badges. If the goal is to show you only useful links, isn´t that a good thing?
Kim Sullivan
I wonder… was this hack inspired by Daniel Glazman’s recent post ( http://www.glazman.org/weblog/dotclear/index.php?post/2008/05/27/Editors-CSS-and-active-links )? ;-)
Dave
Excellent work. Could you add code for all the “add to …” links into the script?
You could also do:
a:visited {background:url(/log.php?url=digg)}
and track this on the server. You could then make the server scrape the homepage and AJAX in more links to check. You cold even brute force 1000s of URLs in quite a short time.
If the bug does get fixed, you can still do:
a:visited {height:10px}
And use JavaScript to check where another element is placed.
Now to check if my visitors have been to any competitor sites…
Aries-Belgium
“I know that you visit: Del.icio.us, and MySpace.”
It’s true that I use Del.icio.us but I don’t use MySpace. I’ve visited the website once or twice but I don’t even have an account there. I actually use Del.icio.us and StumbleUpon and I have the Firefox extension for both installed.

Well you could use progressive javascript to cater for people using noscript. Have it display a list of top 10 in priority, get list of social sites a user visits. If one of them is not in top 10 then remove the lowest priority one… repeat.
Arcao
Hi,
on line 94 in socialhistory.js you have a bug.
The result of concat function is the concated array and it must be set back into sites[site].
Corrected line:
sites[site] = sites[site].concat( moreSites[site] );

Hi Aza,
Should mozilla fix the bug or a user has noscript, there is a javascript-less browser history leak technique that could be implemented.
Paul Irish
Aza,
I’m a big fan of much of your interaction design techniques, but a little unsettled by your lack of transparency on this project.
This work is certainly derivative and I think you should call out and give credit to all relevant previous work:
- Jeremiah Grossman and Robert Hansen discovered the technique in August 2006.
- Spyjax wrapped this up into a nice script in May 2007
- Niall Kennedy proposed using this technique to improve user experience in February 2008 (unfortunately the site is down, atm)
I’m hoping you at least considered linking to Niall, but perhaps decided not to as his site is currently dead?
:-/
ddunlop
Nice idea although I would personally just like to see people remove these buttons altogether.
few notes:
your documentation in the file says to call History() but it actually needs to be SocialHistory().
and you may consider adding http://www.facebook.com/home.php to the facebook sites to check
Aza Raskin
@Kim Sullivan: It wasn’t. I first learned of the leak from the Virgil Griffith, of Wikiscanner fame. He got it, I think from Jeremiah Grossman, who just commted on this post ;)
@coldclimate: Yes, yes you can. And “interest” in other “subversive” ideas—communism and terrorism.
@ddunlp: Agreed. I’d like to see them off of most sites. I also fixed the documentation bug.
@Arcao: Thanks! I’ve fixed it.
Aza Raskin
@Jeremiah: Yep. In my script, I don’t actually check colors. I do display:none/display:inline. If I wanted to be evil and yoink information about the user’s history and send it back to my servers, I’d go for a full CSS solution with an background-image. That gives maximum coverage–no script would have no effect.
@All: I just updated the script to automatically check variations on the URL, adding or removing the “www” subdomain as necessary.
Sean
Definitely a cool trick, but I think it’s way overkill for this type of use. You put digg, reddit, delicious, and mixx on your share list, and if the user users ANY type of social site, I’d say there’s >95% chance they use one of those four. Is it really worth this much trouble to go after that extra 5%?
Jan
That’s a great idea! I love it.
Richard Tallent
Looks like the trackback worked, but not the abstract…
I came up with a variation that solves two problems: it doesn’t require Javascript, and it doesn’t require a hard-set landing page to test.

@Paul: Thanks for the kind words about interaction design. Giving credit where credit is due is a great point. I should have done more research into those that had come before me.

This site sells a service that will alter your site depending on what sites you visited. (I didn’t check but I can only assume that he’s checking the color of the visited link).
Is Mozilla working to close this hole? Can’t that property be made writable but not readable?

Is enables you to detect which social bookmarking sites your visitors use. It cannot enable you to see all of the user’s history. It checks, in a 20-questions style, if the user has been to a particular URL: It’s hit or miss. Social History.Is has a big list of the most popular social bookmarking sites which it checks against.

thx for the article just got a new computer and forgot to install no script in this firefox now i have it so cheers

Cool, I use Facebook and Last.fm, and the script picked up both.

It overestimates the sites I visit. I get: “Digg, Reddit, Facebook, Del.icio.us, MySpace, Technorati, Songza, Slashdot, Ma.gnolia, Furl, Blogger, Last.fm, Fark, and Mixx.”
In reality, I only visit facebook, del.icio.us, songza, blogger and fark. I’m sure I’ve checked out the others at some point to see what the fuss is about. Perhaps you could decrease the false positives by checking for 2 or 3 different urls from a domain instead of just the home page?

Thanks for reminding me why I use NoScript and CookieSafe.

Firefox has options to change link colors to suit the user. Would this work if I set unvisited to, say, green, and visited to blue?
Anthony
“I know that you visit: “… MySpace … and Fark.”
If by “you visit”, you mean “I have been there once, and fled as soon as possible”, then you are correct. But you got the other 6 right. 6/8 Isn’t bad.

How does it help you with me – I use POPURLS.COM
never use or see the sites it links from – to be honest I see
Reddit and Digg as just mental masturbation – the users go on and on endlessly about nothing – just give me links and i stay happy no need for endless blather with endless people who could all be the same person for all I know
=^. .^=
Iphigenie
Clever idea, but only works if you can establish an URL per service that everyone visits – easy for some, trickier for others
Nathan
This isn’t useful. In fact, I consider it an invasion of privacy. Kudos to you for figuring it out and putting this together. But this seems blatantly irresponsible. The only information you should have about a user is what they choose to give you.
jQuery Lover
Great idea.
Sometimes all you need to do is look outside of the box and I guess you did just that when discovered this CSS bug :)
Thanks man.

For a newbie, tech person such as myself, what are the actual steps to implement such code.
Gennick
Hello. And Bye.
Ryan Evans
Very cool. Wondering how long the list of urls could you practically use?
Dean
I must be missing something. I understand what you’re trying to do, but doesn’t CSS of:
#socialLinks a { display: none; }
#socialLinks a:visited { display: block; }
…for something like…
digg
delicious
unvisited
…achieve what you want?

Thanks Aza Raskin! This code is just too sweet, thank for sharing with us all, it’s a blessing. I love the work you do with/for Mozilla.

There is too much information being collected on these web sites that should be kept private. i don’t think people realize how many of our privacy we share without even knowing.

Excellent idea there can be some great modifications to this.
Mark
I’m sort of lost implementing this. I put the code into a page but doesn’t seem to do anything. Does someone have a working example code of this so I can get it working. Thanks so much. Mark.
Donna Liens
Yes me too, i want to put your code in my page but i does nothing, can you explain the “newbies” tutorial about placing those codes in the web page.
I really appreciated.

Donna

Social networking sites are still a good way to promote your blog, website, posts and articles. I use some of great networking services for promotion of my blog and I get really good results. I suggest my friends to promote their blogs on social networking sites.
John Print
A real eye-opener. Guess I need to look more closely at my website……
Alex
Great idea. You’re missing one of the biggest social networks, Twitter.

They stood watching the crane. The lights and the flowers. What were you talking about? It cost eight million dollars. His voice sounded faintly impatient. But I cant issue a public denial! The mind is powerless against them. It is not a combination of interests one encounters nowadays.

This time, Jarak bowed from the waist, his long white ponytail spilling over one shoulder. He stood still, letting them look their fill as they slowly filed into the room. The bowl and spoon remained, but the girl and infant were nowhere to be seen. That was the logical thought. Past Radins shoulder, she spied her parents watching closely, concern utmost on their faces. They sat on the dusty floor of a wide cavern. That Hyle was fascinated by all things magical had brought them even closer together. As She had told her to do, Eyrhaen gave herself into pleasuring Hyle. They had always done all they could for her, even when she was difficult. Ive treated you all miserably in the past, because I could, because you let me. Not that it moved him. Brevin sat on the side of the bed, leaning casually on one arm. Gritting her teeth, she glared up at Lanthan, who was watching her with obvious amusement. They didnt seem to mind. At least, not that she was aware of. She narrowed her eyes and looked back at his face. Radin turned his head to look toward her, smiling. Irin had been beside herself with the news. Youd allow me to breed with another man? No more magic than whats natural?

Thanks for this. Although, it is a bit … wrong. It says I visited “Technorati, Slashdot, and Last.fm. “. I haven’t been there. Don’t like Slashdot attitude, Technorati is new to me (until now), and Last.fm – never been there.

Please add: “delicious.com”! del.icio.us redirects to this url these days…

Hi, I am a new search engine optimizer and I work for infrawebtechnologies.com. this company is in website design and developmennt in India, delhi.
I just started this website promotion through search engine optimization.

If any body can help me in that regard:
point 1: How can I find a large list of website which do free link exchange.
point 2: how can i verify that my website http://www.infrawebtechnologies.com, is performing well and has a good back links?

Hey there. Also one of the annoying ones. I have been to or used Facebook, Digg, StumbleUpon, Del.icio.us, and Diigo, but it says you don’t see me using any of those sites. Currently running the Flock 1.2 beta.

Does not work for me (Firefox trunk).

I use Facebook, Del.icio.us, Reddit and Twitter. Some of those are open right now.

Wow, now that’s impressive!

Brilliant! Apparently D.Baron fixed it long before I read this article, so the upside is that people can guard against it by using Firefox, but users of all other browsers can still see the “cleaner, more aware pages” while giving up a little privacy. :D

It’s an excellent idea, I had thought for a second that it was less useful than it could be because it doesn’t detect that I’ve used my delicious pluggin.
However, there isn’t much point in showing me the icon when I use a pluggin – so it doesn’t impact the usefulness.fvbh
