In hist most recent video, Matt Cutts from Google answered the following question “If you were an SEO of a large company, what would you include in your 2011 strategy?”
Here is the short summary.
1. Website Optimization
Page loading time is a factor in Google rankings. Studies show it also affects visitor behavior on the site (faster site = more sales).
If you use WordPress, I wrote an extensive guide on WordPress Optimization which also covers general website optimization. Also check out browser tools for on page optimization like YSlow, PageSpeed and SEO Doctor.
2. Internal linking
Use relevant keywords for internal linking. Be consistent with internal linking, and do not lose opportunities. Check your links for 404 errors.
3. Social Media Marketing
It is not Search Engine Optimization vs Social Media Marketing – the two work in synergy. Spreading good content on Twitter, Facebook, Digg, Reddit, Stumbleupon creates natural link building possibilities.
