So you may wonder when you see all of those TinyUrl version of links to your site on Twitter if those links actually positively affect your sites page ranking.  If so read on…

The quick answer is mostly no… and the long answer is of course more technically complicated.  First lets delve into TinyUrl.  In case you dont know what TinyUrl is basically it can take any URL and turn it into a shortened “tinyurl” - perfect for microblogging sites like Twitter where you only have 140 ish characters to get what you have to say across and you dont want long urls waisting those preshish 140 characters.

Now the TinyUrls service at the technical end generally does things right.  For example a link to socialguides gets converted to http://tinyurl.com/clpr7g.  And what is happening behind the scene is that when you click on that link it takes your browser instantaneously (so you never know) to the TinyUrl server and they lookup what that URL actually responds to and the forward you off to the real URL before you ever knew your browser went anywhere.

What’s important (from an SEO perspective) about the redirect from TinyUrl is that they do it via a 301 header redirect which tells your browser (in a standard compliant way) that the actually URL has “permanently moved” to the real address.  This is incredibly key as Google passes the pagerank for the original tinyurl not over to tinyurl.com but to socialguides.com, or well whatever the final site is supposed to be. That’s a good thing.

Unfortunately its not all rosey in the land of TinyUrl and Twitter services.  First, because of the nature of tinyurl shortening the link you no longer have anchor tags.  For example if you make a link like this: Techzulu a cool technology blog covering southern california , Google will assoicate the link reference to the Techzulu site with potentially important keywords like “technology blog” and “southern california”.  Now if we look at the TinyUrl version: http://tinyurl.com/ack7de we see that there are no anchor tags and thus less SEO loven.

Now if that wasnt bad enough, when it comes to Twitter the thing I said about the 3o1 redirect that TinyUrl does that allows you to get the “link juice” actually doesn’t even count.  The reason is Twitter takes all URLs found in posts and appends a “nofollow” to each link.  This means that Google will not follow the link at all and thus gives you no credit for said link. This, much like wikipedias implementation, is primarily to avoid spam from blackhat seo folks and the like.

On onehand this really isnt a TinyUrl problem at all so why do I bring it up?  Only because if your link is fully written out on Twitter (in long form) at least you get a little bit of that silly marketers thing called “brand awareness” for your site even if you dont get Google credit for it.  If TinyUrl is used, not only do you not get Google credit for it, you also dont get any brand loven either.

Unfortunately while I understand the Google spam issue, and the reason for nofollow on Twitter it is unfortunate that Google has asked Twitter to implement it that way.  If people are talking about a website then surely that is precisely what Googles pagerank SHOULD be counting to determine popularity/authority/etc.  But that rant is probably for a different post.

So all that said, should TinyUrl still be used?  Probably, because you likely still need to shorten URLs on microblogs and you get what you get.  As for us, we’ll be partnering with a with a very cool company that is still in stealth mode (and arent we all ) in the future that could help resolve some of these shortcomings. Stay tuned.
