Why Adsense Earnings Drop?

Very often, we might find that our adsense earnings suddenly take a plunge during certain days. Why does this happen?

For me, the most common explanation that I can find is that the latest post or article that I have published tends to attract low paying ads. This is very obvious especially when you start to see ads that have little relevance to your site popping up at your homepage or whereever your latest posting is at.

With low paying ads, the same number of clicks translates to a lower ad revenue. The trick then is to make sure that you publish another post or article that will attract high paying ads. Keywords in your blog posts and articles are especially important if you want high paying ads to display on your site.

Example:

You are running a personal finance site and your latest article happens to be about travelling. Well, that will of course attract lots of travel ads which might not be very high paying. The simple option then would be to make sure that you post another article that deals with personal finance so as to draw back the high paying ads. Afterall, readers are more likely to visit your most recent posting.
