Google released “Caffeine” and revealed a new web indexing system
Google launched “Panda” and it started enforcing and regulating its guidelines when it came to “thin” content
Google launched “Venice” and saw “local” search results ranking for more general and broad queries without a geo targeted modifier.
Google launched “Penguin” ” and it started enforcing and regulating its guidelines when it came to low quality links. (Links not relevant, bad neighborhoods, etc.)
Google launched “hummingbird” which revealed a search engine that was more understanding of what users were searching for instead of just indexing results.
