We observed a hit dated 16th and 20th Sept, was it another Google algorithm update?

We closely observe search engine algorithm monitoring tools and recently we observed these tools going nuts on 16^th & 20^th September. We also noticed considerable traffic change on our website on 16^th September & 20^th September 2017.

You may know that recently Google’s Gary Illyes said that search engine algorithm monitoring tools get the report right most of the time, especially MozCast. He said that MozCast usually get it more right than the other tools and this is why we assume that something happened on 16^th and 20^th September.

These third-party tools show high temperature on 16^th & 20^th September. Many webmasters complained about high bounce rate, the downfall of Traffic, low page per session etc. There may be a minor (or major?) Google algorithm update.

Let’s get a closer look at the reports of these tools for 16^th & 20^th September.
