Is there any way to use an include (like an ssi or inc...or maybe something else?) in a plain old static html (or htm) page, instead of turning it into an asp, shtml, php, or cgi page?
Reason: I have a lot of static html pages that are ranking well at the search engines, and I'd hate to change their actual address and lose their ranking and associated traffic.
But....because we keep coming up with new content, we need more navigational ease. Using a universal include would give us three big benefits: a consistent look & feel, easy to manage nav structure, and a shorter header for maximizing our potential with the search engines.
At this point, I'm thinking: don't touch the pages that are doing well in the engines. Apply SSI or INC or a js nav file to everything else in the future.
Or is there another alternative that we should consider?
