4. Vince Update (2009)

Businesses should therefore focus not only on keywords but also on creating a recognizable and trustworthy online presence.

5. Caffeine Update (2010)

The Caffeine Update was mainly a major improvement to Google’s crawling and indexing infrastructure.

It helped Google process and index the rapidly growing amount of information being published on the web.
