A WebmasterWorld thread has an advertiser complaining that Google’s AdWords spider appears to be lowercasing the destination URLs they have. The thing is, the lowercase URLs for this webmaster don’t work with the site and they don’t have the time right now to implement 301 redirects for each URL.

jdMorgan, WebmasterWorld’s AdWords moderator, asked:

The advertiser seems convinced that it is AdWords and not a rogue spider.

The thread is actually turning out to be pretty good with some great details and deeper insight into AdWords crawling behaviors.
