Hello,
When I look at the rank history for a particular keyword, there are missing gaps in the data. For example, the keyword was fluctuating around rank 10-20 from Jan 2022 to July 2022. Then suddenly the line on the graph disappears. It starts tracking again in Oct 2022 starting at rank 16.
It almost appears as if Moz lost track of the keyword for some time. Other tracked keywords did not experience the same issue during this time. Then as a result, Moz reporting will say the tracked keyword moved up in ranking 40+.
What is happening here? I'm unsure how to explain this activity to my clients.
