I was just reading an article by a reputable search engine optimization resource that gives instructions on using mod_rewrite to make search engine friendly links to ones website. For example, the new URL link would be website.com/keyword/keyword2/keyword3 instead of website.com/page.php?id=keyword¶meter=keyword2
I used this code in the .htaccess file of my site to test it out, and the new pretty links did go to the page, but once you got to the page on the website the URL in the address bar had reverted back to the website.com/ page.php?id=keyword¶meter=keyword2 etc... instead of the simplified link URL.
My question is, does this really help my search engine ranking? if the URL once the site loads has converted to the one with all the messy parameters being passed?
