Brad Fogel: No, it does not affect SEO. It stands for "active server pages" which is Microsoft's first server side scripting engine that enables you to make dynamic and interactive web pages. You could just as well use html language if you are not doing any scripting.
Caroline Prideaux: Thanks +Brad Fogel, we don't have any dynamic pages so may as well remove the .asp. Will removing this from the URL damage our page rankings we've achieved so far?
Brent Wildman: Yes it will. If you change the file extension or permalink structure of your website you must 301 redirect the old pages to the new pages. If you don't do this you will lose all of the authority and "juice" that your current .aspx pages have.
Caroline Prideaux: Thank you for your help +Brent Wildman. A 301 redirect will keep all the authority?
Brad Fogel: Yes, it will affect SEO then AFTER changing. If the site has been up using .asp extension AND THEN YOU CHANGE, note +Brent Wildman ;answer.
Tony McCreath: 301 transfers most of the PageRank. Personally I would not make changes like that just for cosmetic reasons.
Marie Dalia: +Brad Fogel ;+Brent Wildman ;Do the same rule apply to .php extension?
Tony McCreath: Yes. The change of a single character in the URL means it's a new page and to keep the ranking you will need to set up 301 Redirects. Even a case change.
Caroline Prideaux: Atm, our URL structure is very poor with no obvious ;hierarchy or no dashes between words. Is it worth changing these URLs and doing a 301 redirect? Or do you think we should we just leave it?
Marie Dalia: +Caroline Prideaux ;Do you ;get traffic for theses ones?
