Last month, some people reported seeing the Green Ad Label yet again in their SERP. The Green Ad Label had been changed to black earlier last month. The SEO Community were no fans of the change. Hence, the news that Google might be testing to bring back the Green Ad Label was welcome.
Google had made no official statement regarding the same. However, recently Danny Sullivan tweeted on the matter. He said that they were not testing to bring back the Green Ad Label. It was visible to a selected few. Those of you who were able to see it constituted the small percentage of searchers. You were left to do some last bit of testing.
He said the Green Ad Label will be fully rolled out in the upcoming weeks. None of you will be able to see it. As of now, Google has left some percentage for gathering data for a subset of searchers.
