Mobile Web is now the mainstream. As a fact, everyone is launching their own versions of mobile websites. As such, there is a need to transform the usual SEO into mobile search engine optimization to cope with the web evolution.

"Mobile optimization and user experience are the same," said David Harper, an SEO guru. But to make it clearer, every SEO expert must have clear-cut views of doing it. Here are some tips to aid you in optimizing your website for mobile search:

1. Your site must link out
2. Use 100% valid XHTML code
3. Adhere to mobile Web best practices (from both the WC3 and dotMobi)
4. Design a simple site structure with clear labels
5. Keep the content clean, short and easy to read on a cell phone
6. Don't build the mobile site past two or three layers
7. Use redirects for mobile users -- Try to have one URL for all online properties but when a mobile user comes to your site, try to redirect them to the mobile-centric site with a redirect
8. Submit your mobile site map to Google

Harper also added other significant mobile SEO tips:

1. Optimize for keywords and short phrases
2. Make sure there are keywords in title tag, H1 tags, H2's, and the content itself
3. Think bookmarks
4. Use keyword rich anchor text for internal links
