When comparing the web report and its export for large sites with millions of backlinks, there can be slight differences in the data. The export can have some data that are not in the web report and vice versa. 

This is because a time-out is implemented when exporting data and our algorithm tries to get as much data as it can within this period. 

Fetching data to be displayed in the front end is a separate action from fetching data for export, hence the slight difference.
