New spider Adsbot-Google to check landing page quality [webmasterworld.com]
tedster's thread includes info about how you must specifically exclude this new bot using its own robots.txt entries if you don't want it to "review" your site in whole or in part.
I haven't seen the bot yet but not having Google's (or anybody's) ads, I don't know if I will.
If you've spotted it, could you post the entire UA string, please? TIA!
