Today I read this cool blog post entitled “Top 3 reasons to use clean URLs“.
In my opinion it is not so big difference for the search engines what kind of URLs you use, but it is cool to have clean url structure mostly for your users. For example I prefer to see a url like web2announcer.com/go/123 instead of web2announcer.com/red/go.php?id=123. It looks better and it makes more sense (people can even memorize a clean url)
As for SEO it seems that clean urls get faster pagerank, but I am not sure how significant is the pagerank in our days….
Anyway this was a nice read, so I just bookmarked it 🙂
