What do You Know About Google SEO Algorithm Update ?

[Richard]

With all of those algorithms and perhaps the upcoming ones, the key is to make search engines believe that you are not doing SEO as you acquire web presence. That said, you need to:
1. Stop focusing on keywords alone and consider semantics (or synonyms) when doing SEO
2. Vary all links (high PR, low PR, nofollow, dofollow, etc) from all types of sources
3. Vary anchor text
4. Ensure relevancy
5. Interact, share, and connect through social media
6. Internal back linking (pages as opposed to home page only)
7. Competition - if you competition keywords only has 100 links, then you better not have more than 10000! or risk being flagged with overoptimization
8.Vary profiles, IP addresses, and browsers
9. HIGH QUALITY CONTENT for the users
10. Highly compliant website - on page SEO

There are more suggestions but these should get you started.
