SEO - Changing file extension
Is SEO effected when URL changes from .php to not including .php? For example, if you change a URL from http://www.example.com/about.php to http://www.example.com/about, do you lose the earlier SEO impact?
I am replacing an older website, and want to keep the URL the same for SEO purposes. The problem is that the older URL includes .php at the end.
I'm replacing the website with a new wordpress site, and when I add the (.php) to the URL, the formatting is disrupted. I can create a URL that is the same, but I can't add the .php at the end.
Does anyone know how I could add .php to the URL without having the format be interrupted?
