Why is topic important?

Different ads pay different amounts!

Advertisers bid on keywords - the more popular the keyword, the more they bid.

If you are writing about some obscure topic like 18th century spoons, not many advertisers will be bidding on those keywords. This means they don't have to pay much to Google and thus your share will be even smaller - perhaps only a few cents per click.

On the other hand, some topics are so popular that you can earn dollars for each click!
