I use a footer.html file for many of my sites, and I use SSI include to put the footer on every page of my site. Obviously, I have to make every page .shtml as well. I was just wondering if search engines can follow my footer and the links in it?
SSI stands for server side include which means visitors (and thus search engines) cannot tell the difference.
Do I have to make each page .shtml? For some reason, that bothers me... Are there any cons with using .shtml?
To use SSI yes you do. Alternatively, you could use PHP includes on normal html pages and in your htaccess add a line to tell the server to parse PHP code.
Way over my head.... Ill just stick with my ssi include and hope that .shtml wont negitavely effect my site.
.shtml will definately not affect your site in a negative way. It doesn't matter what your extention is. The se's will read and rank a .html or .shtml or .php all the same. It's the dynamic url's that screw the se's up and even that has improved a ton.
