What it is

The AdSense crawler. It reads a page so AdSense can choose relevant ads for it, and it is a special-case crawler that ignores the robots.txt * group.

What blocking it costs you

Pages it cannot read get generic, lower-value AdSense ads or none at all. This is the one block on this list that costs you money directly if you run AdSense.
