Change over time covers all sites, not just the sites visitors scanned.
These lines count the sites scanned in each calendar month, so a month's figure can differ from the headline figures above, which use each
site's latest scan from the last three months. The “All sites” column is every site scanned that month, including sites added since, so a
change there can be a different crowd being scanned.
“Same sites” is every month for the one group of sites scanned in both the first month with a figure and the latest month, so a change
there is the sites themselves changing.
