There are several different web programming languages available....all with different features and different capabilities...but as far as SEO is concerned,which is the most SEO friendly programming language? Is it PHP,ASP or HTML ?
HTML is a markup language while PHP and ASP.NET are development languages that are used to generate HTML. Whichever backend language you use, they all have the capacity of being equally SEO friendly. However, they also all have the capacity of being not SEO friendly at all. Always follow SEO best practices.
In my own experiences, HTML would be the best for coding a site since you might have known all scripts basing on PHP, ASP or others would offer some kinds of SEO add-ons for transferring dynamic urls into static ones. Of course, search engines would have no problems in dealing with dynamic urls these days. There might be tiny difference between all that programming languages.
