I am developing a static website (don't need any server-side support. I have Basic HTML and JAVAscript) which have a number of pages.
all pages have the same top menu (header) and footer. what is the best practice considering SEO?
I have two options :
Option 1. Should I copy header.html & footr.html code on every HTML page?
Option 2. Should I include header.html & footer.html on every HTML page?
which Option is better? Does any of them affect SEO?
if Option 2 is the right solution then my follow up question is "How to include common header.html and footer.html ?" I don't want to use PHP/ iframe.
