hello.. what's the impact of changing the file name of your html files when it comes to indexing? the site has been indexed by google before but when the file name were changed and when i edited the index file... it was gone on google's index??? i have submitted the site on google to crawl 2 weeks ago but i haven't seen any changes til now... hope you can help... thanks!
if i change the file name of a page i keep a copy of the old page on the server for a few months. This way google has time to index the new page and can still send traffic to the old page.
It is always better to redirect the user from the old page to the new page. If its a server side script you can redirect through 302 (etc) Moved headers and google will automatically reindex the new page, or you can provide link to the new page in the old one plus META Refresh redirect to the new page.
