I'm updating a site that is currently static html (i.e. index.html). I'd like to pull in blog posts into the page and only know of SimplePie to accomplish this.
Question 1 - If I update the site from .html to .php is there a hit in SEO while the Search Engines re-index?
Question 2 - Is there a way to use Server Side Includes to include a .php file of my SimplePie results, or another way to pull blog posts directly into a .html file?
I'd appreciate advice.
