Google Algorithm Update Checker

Update impact analysis

The main output of the checker is a graph with google organic traffic with the dates of the updates superimposed. Updates where the likelihood of an effect is high are highlighted. The determination of the likelihood of an impact relies on deep analysis, including seasonality adjustments and ruling out other reasons for any traffic change.

An update which is not highlighted likely has no effect, even though there might be a traffic drop. If it is unclear why an effect has not been highlighted, investigate the traffic year over year and check for Google Analytics tracking issues.

Page-level drill-down

Some updates have a page-level effect which might not be visible on the overall level. Including only particular pages in the analysis, or excluding some pages might produce more accurate results in such cases. Obviously, this would apply mostly to larger websites and especially if different sections of it have significantly different qualities.

In-depth investigation

Once an impact is determined, the tool shows a graph demonstrating the before and after difference that makes it easier to spot if there was an organic traffic drop or increase.

The detailed update description which is available for all updates also helps in determining the reason for the impact and therefore to determine the best course of action, if any.
