Welcome to the Q&A Forum

Have you confirmed that Googlebot is being redirected as well and it's for sure a 301 redirect? If the redirects are IP based, it's possible Google figured out that there is an IP redirect (which is NOT recommended) and therefore, for a brand search, are giving the main domain with the US content - which is all they can see with an IP based redirect. For your third question: Stop the redirect. Use a JS prompt to ask people to set a location preference and set a cookie based on that. Use sitemaps to push all country content to the SEs. Think about a responsive site rather than an m.domain.com - but if you must have that, make sure to make a separate sitemap for that and claim it in Webmaster Tools. Ensure that your mobile content is marked up correctly and if needed, the right canonicals are in place.

SHTML is an old-school way to use SSI (server side includes) in what is otherwise a static HTML page. Stack Overflow talks about this in more detail here: http://stackoverflow.com/questions/519619/what-is-shtml Web servers know that if the page is .shtml, then it's okay to run inline php code, for example. My guess is that your .shtml files are older remnants of SSI files. I'm not a big fan of changing URLs just to clean up things, because if you change links you will need to use a 301 redirect, and that will keep about 85% of the SEO value of the original link. If you do want to use inline php code on .html pages, I agree with Travis, above. You can modify your .htaccess file with: addhandler x-httpd-php5-cgi .htm addhandler x-httpd-php5-cgi .html (This will allow you to run php in static HTML files, without having to change the file extension to .php) Hope this helps!
