Last week, Google launched the Search Analytics report to all users but there were these two vertical lines that read "update" in the analytics chart that people had no clue what it meant.
Some savvy SEOs and webmasters dug into the code and found a broken link linking to the Data anomalies in Webmaster Tools page but now you no longer need to be a sleuth to find the link, Google updated the chart to add a "learn more" link when you hover over the two dates that have the update line:
Here is what each data anomaly is:
- April 21 -Mobile usability introduced as a ranking signal. Mobile-friendly websites get a boost in Google search results.
- March 31 - A logging error incorrectly reported a drop in impressions and clicks. No actual drop occurred.
