Moz: Google’s diversity update was pretty minor
Moz’s findings. “While Google technically improved site diversity, the update was narrowly targeted and we had to dig to find evidence of improvement,” wrote Moz’s Pete Meyers. “The impact of the site diversity update doesn’t feel on par with a pre-announcement and the PR it received. Regarding the state of site diversity in SERPs, Google has made minor improvements but still has work to do,” he said.
Just to be clear, this looked at the company’s 10,000 keyword data set, it did not look at the infinite number of queries this may have impacted. Also, brand or navigational queries were probably the exceptions to the rule when Google said they may indeed show more than two results from the same query. Someone searching for a specific brand likely wants to see more results from the official site and Google likely will show that company’s domain more than two times.
But there was improvement. Moz dug into its data and said, “between June 6th and 7th, average diversity did improve marginally, from 90.23 percent to 90.72 percent (a 0.49 percent improvement).” The chart below is zoomed into the data at 10 times and he said “improvement hardly seems impressive.” Here is that chart zoomed in:
