Re: Internet Explorer problem
Nah, you’re way off base mate.
Your code wasn’t able to be read or validated by a parser, and had 2 Document declarations in it, so instantly it would have affected it’s SEO.
Also a container DIV called Title outside of the HTML acts against your SEO rather than for it, as it’s considered word overloading – something frowned upon by Search Engines for the last 10 years (thats if any search engine read it, given that it was outwith the HTML).
Just stick within the rules of web development and you’ll be fine
