I've just had a thought and interested to hear peoples thoughts.
Does it make a difference to SERP's whether or not the urls to internal pages are relative or absolute?
i.e. if you had a page located at www.mydomain.com/products.htm and you wanted to link to a file called 'services' in the same directory - would it make any difference if the link path was '/services.htm' or www.mydomain.com/services.htm.
I realise that there is no need to use absolute paths to internal pages but it is apparent that some content managment systems require this.
The question to ask is would it in some way improve the results of the search engines to make a distinction? In this case, I can't imagine it would - so ther eis very little chance any engine implements it.
I took over a web site 2 months ago that had 86,000 listings in Google, and top 3 listings in all its industry-specific keywords. I was astonished at how successful the former webmaster had been at promoting the web site. You guess it, every link had been coded as an absolute address.
Incidentally, the domain name had to be changed on the web site, and it took 6 hours of an automated search-and-replace operation to change the URL's on all the pages.
The domain name was three keywords separated by hyphens... not sure if this strategy is as effective as it used to be, but I wasn't about to change it...
