I have a website with a "tips" section administered using WordPress (the rest of the site is made up of basic HTML files).
For multiple reasons (including security and the fact I rarely add content now), I am now going to be removing WordPress and am manually preparing .php files with hidden extensions etc so that I can re-upload the content in the exact same location as it is at present. Everything is sorted; theme, content, etc; it's all identical to how it is on WordPress but just as standalone pages.
I just want some reassurance that once I've deleted WordPress and re-uploaded the standalone PHP files that nothing "should" change in the SERPS? In the search engine's eyes, the content is the same, the URLs are the same, internal links haven't changed, etc - the only changes are in the backend with htaccess re-writes to "hide" the .php extensions, etc.
