Hey all, I was wondering what is the best coding language for google, I have multi sites in html, xhtml, php, css - but which does google prefer?
The markup language that you use like HTML, XHTML doesn't really matter much. However, make sure that your code is W3C compliant. The programming language that you use like php or asp also doesn't matter since the code is not shown to google. However, again make sure that your output is W3C compliant and the urls are optimized for search engines.
It doesn't matter what server side programming language you use, they all render HTML\XHTML the same. You should choose by your needs for your website.
I've used html and php both with the same results. Focus on linking and content more than anything else.
