Possibly good news for many members here who have been discussing a noticeable drop in average ranking positions since July 13 or 14....
If this was Google Search Console data, the reported drop in average positions doesn't necessarily mean that your rankings have fallen. It could be indicating instead that Search Analytics has improved how it logs data. Report of the GSC change is here....

>>July 14 - onward
An incremental improvement in Google's logging system now provides better accounting for results in lower positions. This change might cause increase in impressions, but also a decrease in average positions. This change only affects Search Console reporting, not your actual performance on Google Search.
The above change was announced by Gary Illyes in Twitter [twitter.com
...] and reported Wednesday morning by Barry Schwartz in Search Engine Land [searchengineland.com
...] Thanks to Barry for staying on top of the story.
For some, though, according to discussion in our "July 2017 Google Updates and SERP Changes" thread [webmasterworld.com
...] ...there may have been actual ranking changes as well. In light of the Google announcement, it's hard to know from various comments in our thread which were ranking changes and which were reporting changes. "Average positions" can be a very fuzzy term.
