Google is to show advertisers how many fraudulent clicks the search giant detects.

The search giant has always removed dodgy clicks and advertisers do not pay for them. But because figures have been secret there has been suspicion about the size of the problem. Google maintains it is not a huge issue but many observers disagree.

Advertisers will now see total fraudulent clicks as well as what percentage that makes of total clicks on any advert.

Clicks are counted in real-time.

The issue is likely to remain contentious - Google has an ongoing court case on the subject.
