Google will offer info on an advertiser's history
 

Have you ever seen an ad for an unfamiliar gadget or clothing label and wondered if it was above-board? You might get a more informed take soon. Google is introducing advertiser pages in the "about this ad" section that not only provide more details about a verified marketer, but show the ads that company ran in the past 30 days. If you're suspicious, it's easier to report an ad.
