It’s been mentioned previously that AdWords has been going through some serious changes.  Well, it appears that they are also stepping up in their quality check on their advertisers.  Google has taken action by banning some of their advertisers that don’t meet up to standards – permanently.

This is quite major news for several advertisers.  These bans are hitting hard, and the first major revision on AdWords users and who Google will accept was done yesterday, December 3rd.  The Search Engine Roundtable has more information and a good copy of the ban letter that they published today.
