Google continues to constantly refine its algorithm to deliver more relevant results.
This makes sense as consumers would likely start using an alternative if every search yielded poor results. According to some estimates, the search giant changes its algorithm hundreds of times a year. But occasionally major updates are rolled out that affect the results in significant ways.
Last year, Google started globally rolling out an update that makes mobile friendliness a ranking factor. This meant that rankings for a site would suffer in the mobile search results if it was not optimised for mobile devices.
Now it appears that Google is testing various changes to its ranking algorithm.
Here are graphs from a number of tools that track fluctuations in rankings:
So what exactly is going on?
Google making updates to its ranking algorithm is nothing new of course. But the recent fluctuations is an indication that the search giant is indeed testing new changes or making core updates. Google has yet to officially confirm the update but many are speculating that it is a new version of Penguin.
