A Googler's Sage Advice on Absolute vs. Relative URLs

Jun 10, 2008 - 7:11 am 2 by

A common question in the SEO space is should I use absolute or relative URLs. Absolute URLs are when you link a URL by using the domain.com portion as well, so linking to my authors page would be a link like https://www.seroundtable.com/authors.php. The relative URL for that authors page would be a link like /authors.php.

As you can imagine, there are pros and cons. JohnMu, a Googler, has an outstanding post in a Google Groups thread with sage advice. It would be a crime if I did not quote the whole post, so here it is:

There are pros and cons to both absolute and relative URLs in links:

Absolute URLs: + help keep the links pointing to your content if someone were to copy it (*) + help keep the links pointing to your domain name if you cannot select a canonical (can't do 301 redirects) + help make sure that you're pointing to the right URL even if you move things around (say for stylesheets or graphics) - cannot be tested on a staging / testing server (eg locally) (unless you insert the links dynamically) - makes it hard to move content (unless the links are inserted dynamically)

Relative URLs: + make it easy to move content around + make it easy to test locally and on a staging server - are easy to break if linking to content that isn't moved as well (stylesheet, graphics, etc) - an evil scraper would have less work (*)

There's a middle ground as well, using absolute links without a domain name, eg: < a href="/resources/green/mostly/page.htm" ...> Personally, I prefer to use relative URLs + some absolute (without domain name) ones to shared resources. The advantage of being able to test things out 1:1 on a staging server can't compete with the pseudo-protection against scrapers.

The only place I would use absolute URLs would be if the site is hosted somewhere where the webmaster can't do a 301 redirect and may have trouble with duplicates. I've seen this a lot with sites hosted on a free account with the ISP; often it will be hosted as http://isp.com/users/~name/site ..., then perhaps http://domain.com/site... and http://www.domain.com/site... . By using absolute URLs in that situation, any value passed to one of the wrong URLs will automatically pass value to the correct URLs as well.

If you have a really good CMS you may be able to change from one to another and use a staging server without much work. In that case, it probably doesn't matter which one is chosen.

Solid advice!
