Now I understand the whole 'we believe in our products' but this is just insane.

I searched for 'Google Chrome' (I am not sure if Google has a standard URL for its products - I guess they do follow the google.com/product but you won't always get it right. For instance it's google.com/talk and not google.com/gtalk) and I got the above SERP.
Now why would they have a Sponsored Listing when they can have such a strong Organic Listing. Well it's alright to have an ad when there are other advertisers (not sure if Chrome is Trademarked or not so not sure if they can block other advertisers from show in - they can't in the United States because their Trademark Policy is different for US/Canada but I searched in India).
Even if they do have a marketing budget that they have to exhaust, they shouldn't use it on the brand term but rather on generic terms.
Also is isn't like someone who is looking for Chrome will settle for some other browser. So even if there are other advertisers, I don't think searchers would sway just because they saw ads (unless the ads said and the landing page proved that the browser being advertised is better than Chrome. But I still don't think that that is good enough to sway a user looking for a Chrome download).
Well it doesn't make sense to me. Let me know if it makes sense to you.
I am not even going to get started about the Ad Copy. I am sure they get brilliant CTRs on this ad but the CTR will have little or nothing to do with the copy of the ad.
