Google Stop Showing Adverts To People Who Don't Click Them
Google are testing out a new way of displaying adverts on their search results pages. It turns out, According to a post at webmasterworld, That if a user makes multiple searches, But clicks no adverts, The adverts that would appear at the top of the page in the blue box are moved to the right to make more room for the organic results.
This is a pretty good move by google. It means if a user has no intention of clicking an advert they will not be shown them. Advertisers will also like this because it means they wont be paying for visitors who have clicked out of frustration of not being able to find what they want.
At present i believe this feature only exists on a few datacenters, I tried earlier by searching the term "SEO" and after 5 searches of the same term the adverts at the top of the page were removed.
