I have a lot of SHTML pages.
If I change these to PHP to add some more functionality (obviously changing stuff like includes to PHP where necessary) will this effect how search engines index my site? (most importantly Google)
Will they still index the PHP files the same as the old SHTML and just as often, etc.?
Will there be any difference?
This is my thinking/reasoning behind this question. We have a lot of shtml pages.
I think it's because Google will index them all.
E.g.: If you have a file individual_page.php and essentialy this page is many pages; individual_page.php?id=39430403 then Google won't index each one right? But if I have static files, they'll index them all, right?
