So I have a website that has greate Search Engine rankings, and like 500+ html
pages.
I want to unify the header and footer into one file, but don’t want to change the
.html file extension to a .php file extension for fear of an SEO hit.
So I tried:
<!--#include FILE="header.html" -->
And it worked on my server, is there a downside to this?
Like future updates to the godaddy server rendering my header/footer invisible ?
If your server is Apache, you can use mod_rewrite to convert a request for
foo.htmlintofoo.php. But setting up rewrite rules can be tricky, and it sounds like you already found a solution that works, so you should probably just use that.
