Welcome to WebmasterWorld Guest from 220.127.116.11
Hoping someone can throw a little light on a little query.
I'm redeveloping a site and implementing php into it.
Every page is remaining in the same location.
What I want to know is will my current search engine rankings ( especially google :P) be affected in any way if I went live with the change? My initial feeling is no but just wanted to check with those who are much more savvy than me!
well, no page is actually staying in the same place, if you change the extension it's a different place
your rankings will probably tank
your best plan would be to keep the exact same urls and just enable php parsing for the html extension.
forget mod_rewrite for this, just don't change the extensions
