It must be frustrating to search for your own name on Google and find things you would rather not be in the public domain.

This is what happened to Mario Costejo González in Spain, when he discovered a newspaper article about his eviction in 1998 online.

Taking his complaint to the court, he has won the "right to be forgotten" online - and his complaint was not against the newspaper, but rather against Google.

The implications of this for the search giant are enormous - and the true scale of the issue is to be played out over the coming months.

Below the fold... it's a term borrowed from newspaper advertising. When a broad sheet newspaper was folded in half and then stacked on a newsstand, you could only see the top half of the front page. Everything else was, well... below the fold.

The internet has borrowed this term to describe ads which are on the web page being browsed, but not visible unless the user scrolls down, and there has been a lot of talk over the past few months about whether Google should count an ad which is never seen as an impression. It's along the lines of trees falling in forests and no one hearing them....

When there is a problem that needs fixing - start your checks with the most likely cause. That's good advice in general - but even more so with Google AdWords.

More than once I have found myself delving deep into account structure and global settings to "fix" a problem only to have a Homer "D'Oh" moment... here are a few of mine, and in this show and tell post, I'd like to hear some of yours!

So you start an AdWords campaign and you start to get traffic. You're doing all the things they tell you to do - you've got Google Analytics installed and you've got conversion reporting configured. You know exactly which keywords and ads are working and which are not - so now you can start really optimizing your account. How long will it take you to paint yourself into a corner?

If you're not careful - it could be quicker than you might think.

Google have just made a big announcement about the big announcement they are going to make about AdWords on the 22nd April - and there are a bunch of predictions about what is likely to be included.
