Yesterday I was searching abnout landing page testings. When I search the query “landing page testing” , I was wondered that the search engine result page contains the following screen shot. Here I have circled that different feature in SERP.

It has two different options that PROMOTE and REMOVE. when I clicked on REMOVE, that particular site was disabled from the search engine result page. When I click on PROMOTE for a particular url, that site is one position moved into above the SERP.

PROMOTE is represented here as upward arrow.

REMOVE is represented as cross symbol.

I don’t know whether it is google’s algorithm changes? If anybody see the same changes in your SERP means you can share your thoughts over here. Comment me if anything from my side is wrong or right.
