I am just learning SEO and i found this article very useful for beginners like me. Here are some points that i found useful as well:

1. Never forget to add alt tag in image.
2. Never think that google can’t read CSS in your hidden DIV.
3. It is not compulsory to your URLs in .html.
4. A html sitemap is not only for google boot. It is for human as well.

Thanks for sharing. Search engine optimization is indeed one of the most crucial areas in Internet marketing, it is a perfect bridge between technology and business….
