There has been a confusing algo update that took more time than usual to stabilize. According to Rank Ranger, it made the most significant impact on the positions 6-10 (not that other positions weren’t affected, but the extent wasn’t as nearly as great). Webmasters didn’t pick this one up as quickly as the tools did, though, and it took them a bit longer to react. The real consequences of this update are yet to be determined.
Local ranking algorithm update
Fluctuations were spotted with Google local results between June 11 and June 18, indicating that they have done some major updates to their local search.
This update probably started on the 17th of May; however, while the tracking tools went bananas, it took quite a while for the webmasters to pick up on this one. There are indications that this has been some sort of a quality-related update.
There was massive volatility on April 17 and 18. The webmasters were quite vocal about their findings, and the tools also picked up on this, which suggests a rather significant update might be on the way.
Guidelines targeting offensive, upsetting, inaccurate and hateful results
New quality rater guidelines are out, specifically updated to tell the quality raters how to detect offensive, upsetting, inaccurate and hateful pages. The purpose of this is to make the algorithm more accurate when penalizing this type of websites.
The so-called “Fred” update is officially confirmed. It affected quite a large number of websites. Google classified it as a quality update. Ad-heavy sites with low-quality content saw the heaviest penalization.
A big one
There has been an update accompanied by wild fluctuations in SERPs. Although unconfirmed, a vast amount of analysis suggests that it’s primarily related to content quality and site usability.
Big in Japan
There was a significant quality-related update targeting only Japanese market. Google Japan confirmed it.
Links and PBN
This update was spotted more by the tools, than on webmaster forums. However, it was discussed on black hat forums. It seems to target links, mostly from PBNs.
There was a small update spotted both by webmasters and the tools. SERP fluctuations have been more pronounced than usual, but not alarming nevertheless.
