All URL shorteners created equal? Not!

[PhilipSEO]

We all use URL shorteners these days, but what are their implications for SEO? Do they pass link juice? What extra capabilities do they offer?

The best URL shorteners, like tinyurl.com and bit.ly, use a 301 redirect (which passes most of the link juice if the link is "dofollow") and also provide tracking.

For a detailed comparison of the most popular shorteners, I have found this article helpful:

PhilipSEO, I have had a question swirling around my head the
last few days.

What is "seen" as the referring page in respect to using bit.ly?
Does it look like the referring page is bit.ly or the site the link is on?

^Yeah I'm wondering the same thing. And I always use bit.ly so I guess I'm using the right stuff

I was one of the developers of BudURL (I no longer have any relationship with the company BTW) - and had some early conversations with the creator of Pretty Links. And no, there is a serious misunderstanding of how web servers, browsers, and corporate proxies see redirects.

Which is why both BudURL and Pretty Links offer a 307 Redirect.

And I have seen first-hand Googlebot encountering a 301 and never revisiting that URL again.

See: The anatomy of a server sided redirect: 301, 302 and 307 illuminated SEO wise and BudURL University: 307 Redirects | Power to Grow

@pbarnhart Thank you for this information and for the references (yet to be checked out). But could you please elaborate on your experience with this (as well as on when this took place)? It would seem to be silly of Google et al. to ignore shortened URLs for discovery purposes, seeing how popular they have become (not least because of Twitter and such).

@Paul and Charlie, regarding whether the shorteres show up as referring URLs, I am not sure myself. I am testing this now and will report the results tomorrow!

Nice post Philip. I always assumed they were all fairly equal. Glad I've only been using bit.ly

Who needs ugly: .../rUoI3x - type URLs?
It's always struggle to type them (some magazines use them) and they never give a hint on what link is about unless it comes with description nearby.
I am using the right shortener - I registered my own pretty lovely domain: toprate.org and put all my shortened links in it with the names i want, with redirects I need and on my terms.
I crafted tiny PHP script on it to handle everything.
It's not the shortest domain name in the world but i love it.
There are plenty of lovely short domains available for creative "own" URL shorteners.

Well, they make it very easy to copy and paste.....

I use them for twitter, which when using a canonical blog (and you should) like
blogspot, the url gets very, very long depending on the title. does not fit
in twitter along with a by-line in 140 characters. The blog url alone has
almost 50 characters, including the http bit.

Even if you don't blog, your urls should look something like:
http:// www. my domain .com/keyword-keyword-keyphrase . php
Even some of those could get quite long. Not twitter friendly.

Obviously, if you don't twitter, and blog or use long tail canonical urls,
you have no need.

I use it for something else at the moment, testing something, and that's why I
am looking at getting to the root of what the history is on a redirect. If it is a 310
redirect, I am assuming that the bit.ly would not show up in any history, but
search engines might catch it as a middle man, so to speak. That's what I would
like to find out.

I heard twitter is creating their own and that may spell doom for bit.ly.
Something of an auto-shortener.

301 redirects will not show up as the referrer - the original site will. So, if a user clicks on a bit.ly link on a twitter page, Twitter will show up as the referrer.

Googlebot has no/little need to visit a 301 redirect again. 301s are permanent redirects. So, once Googlebot finds the destination URL, that is the page they will continue to visit. Now, I would expect (but haven't confirmed) that amply linked-to 301 URLs get visited from time-to-time just at a far lower frequency than the actual pages with content.

bit.ly lets you rename them to whatever you want...

Thanks for the info. I have never used those before, but may have need in the future.

Thanks, Paul, for asking this: I wasn't sure of the answer myself, but I have now tested it. And here are the results:

1. 301-based URL shortener without preview: the original site (not the URL shortening site) shows up as referrer in Google Analytics

2. 301-based URL shortener with preview: the URL-shortening site shows up as referrer in Google Analytics (not the original site)

I hope this is of interest!

No, this is incorrect. Google admitted earlier this year that 301 redirects degrade the link juice to some degree. Moreover, since the MayDay and Caffeine updates, 301s appear to further weaken the link juice passed, at least when the 301 is from one website to another.

Yes that is of interest.

I was thinking the same thing on the 301 redirect. This is actually a very good
thread that morphed into some 301 info. I thought maybe on some basis, the
301 redirect would show, but then how could it, logically speaking. There would
be no page load to put in any history. I thought maybe clever google would
see it and detect something from it, just what I could not come up with. I wondered
how they saw the incoming links.

The preview makes a little sense, but one would have to go past the preview, right?
I've used the once-popular hello.to/keyword in that past and now they put that
in an iframe or frame, so your site looks like the short url. hello.to is one of the
coolest looking url "changers." I just checked one I made 10 years ago and it
still works!

i know that tinyURL works exactly as a 301 redirect so it pass the pr, however when you do 301 redirect you lose some link juice.

still ranking affiliate links on google is not easy. i used to have few affiliate links on google 1st page, ibuild hundred back links to them and after a while they lost their positions. so for the long run it doesnt work, i spent lot of time on it just to understand that it is better to rank with your review page than your affiliate link
