Possibly of interest for followers of this thread... we received a post in Google SEO that reminded me of this discussion. It was a report of a browser testing site that's running a script on distributed computers.
It leaves a footprint similar to what's described here, and it was similarly messing up the poster's AdSense impressions, etc. As the OP described...
Footprints, something to look for:
- many visits in a relatively short amount of time with a 100% bounce rate
- visits extremely varied in terms of browser used and mobile vs desktop.
- IPs and referrers are of no consequence, the IPs change between visit groupings and many IPs are used per event
- entire page is loaded including ads
- all hits will be to the same page but each time the script is run any page can be selected
Magnitude of the effect and other signatures not the same. The thread is now in Webmaster General, and I've cross-linked it to this one. Perhaps the discussion will provide some clues....
