Three changes have been reported in the SEO world this week, and these changes are mainly about tests and updates carried out by Google.
1. Google may have made a March update.
In the past few weeks, many have been speculating about the possible arrival of a Google update. No confirmation has been made yet, but current data on search rankings have shown that there have been significant signs of an update.
2. Google has been using images in SERPs.
Have you noticed thumbnail images showing in the search results listings? Many believe that this is a sign that Google has been testing the use of images in their SERPs.
3. Google added extra filters in their image search.
Google introduced color filter buttons in image search. The buttons will allow users to filter results by categories, similar to a search feature traditionally seen in Pinterest.
