This is excellent and does exactly what it says it will do. I've used it to check out all the competitors for our local business clients and it's picked up companies who I didn't know were advertising.

Now we can see what they're doing and exactly what they are saying in the ads without messing about using Google's disclosure option.

The only thing I had reservations about was the lack of national geographic targeting, but they've now added this so that I can use it for our own company as well as our clients.

Highly recommended.
