Hello Everyone. I need little help here. Just want to ask if the link extension .php ,could still be crawled by Search engines? Is this a good practice of SEO? sample link is "http://www.popout.com/one/friendship.php" instead of http://www.popout.com/one/friendship.html I know .html is crawlable but what about .php ?? Oh anways, the links given are just sample links it's not existing..
Probably will be OK seeing you have no "variables" in the link. When you start seeing those, you "might" have a problem. If you have an Apache system, you could put a ModRewrite in the .htaccess file and convert PHP htmls to htm(l) extensions if you so desired. Ex: Options +FollowSymlinks RewriteEngine on RewriteRule ^(.*)\.php $1.html [nc] This should not be used if you have session info or variables in your site though. It can however be done with variable info in URL's, but requires a more complex ReWrite...
The server side programming language to render the HTML is not a factor in crawling, they all render HTML to web browsers and search engine crawlers, hell you could make your own unique file extension and still be crawled just fine, just set .htaccess to parse accordingly if you choose to do so.
