Both Google and Yahoo claimed that Internet gambling ads would be removed from their search results by the end of April. However, even after almost a week, it has been discovered that users still can access unauthorized sponsored links to gambling sites in sites such as About.com which has a partnership with Google, even earlier this week.

Prior to the censorship, a typical search result on say 'online gambling' or even last week's Kentucky Derby and 'horse racing' threw up Google AdWords, and displayed text ads for Internet betting sites.

After few media outlets, questioned Google about the ads, the search engine has now removed the ads from search results. Google automatically posts ads that pass its automated filters, and eventually subjects those ads to human inspection. Any changes to the search firm's system affect result listings on its site, as well as links and ads it serves to partner sites. Google officials, declined to comment on this issue.

'It appears that Google doesn't like to do anything manually; they want to have it be automated. People are just reposting their ads ... They're making hay while the sun shines,' explains Brad Fallon, CEO, Smart Marketing Inc. Fallon, who runs an interactive marketing consultancy adds that as a result of Google's ad ban, some advertisers that sell things that appeal to a wide audience, like online shopping sites are taking advantage of depreciated bid prices by purchasing web gambling-related keywords to advertise their unrelated offerings.
