Search Engine Optimization and php
I am currently building a website to sell my art online. Specifically, I am customizing and setting up the shopping cart and downloading software I bought for it. It is written in php. I have just been thinking, will the fact that it is php confuse the search engines? I am thinking of integrating the rest of the site (the info about me, links section, and so on) into that same engine, since it will be simpler for the users.
Any ideas on how to optimize php code for the search engines? Or is it the same approach as optimizing html code?
