"Health" report on AdSense main page

The report does not seem to be 100% accurate, or at least slow in getting things right. It took several weeks for it to tell me that I am fully optimized for revenue, even though I haven't changed anything from when the report first showed up and told me I was barely optimized for revenue. So take what it says with a grain of salt.

A grain of salt? I would ignore it completely.

The inference behind producing it is clear but as far as I know there is absolutely no connection between the score results and anything else - earnings, SERPS etc.

Indeed, if you have more than one site on an account, how does big G report your "health"? And if there is some logic to that "health" reporting then G is not letting me in on the secret for sure.

It's typical frightening tactics but G simply doesn't have the ability to actually do anything with the results.

I never pay attention to it.

They give you a bad report if you don't have image ads. They report erroneous spider errors. They make a big fuss over certain things that don't matter.

You should enable Google+ on all sites if you can, however.
