What chart notes can you display on the "Performance" graph in Site Explorer? Multiple answers may apply.

The "Performance" graph in Ahrefs' Site Explorer allows you to overlay specific events as chart notes to help interpret traffic fluctuations. Google algorithm updates are a crucial factor influencing organic search performance, so displaying these helps correlate traffic changes with known algorithm shifts. Similarly, Ahrefs keyword database updates can impact the visibility and accuracy of the data presented in Site Explorer, making them relevant for understanding changes in reported metrics. Custom user notes are not a standard feature for chart annotations on this graph. New SERP feature releases, while impactful, are not directly displayed as chart notes on the "Performance" graph within Site Explorer.
