Ever since the first Panda update back in 2011, the world of SEO has never been the same. What followed could only be termed subtly as a nightmare for every blogger, internet marketer and SEO agency. However Google’s intention to clean up the spam started working out for the greater good (though one could still argue about its alterior motives, Adwords?) but nevertheless spam has decreased and webmasters now focus on producing better content and an overall better user experience from their websites. So how about a timeline of these animal updates (panda and penguin) from Google? Well, folks at marketingsignals.com have designed an interesting Infographic just on that. Let us know what you think of it in the comment section. Feel free too share this IG on your blog as well.
