Changing Metatags

Metatags certainly aren’t what they used to be, and in AdSense they’re
barely anything at all. There’s a good chance that when it comes to deciding
ad relevance, your metatags have no effect whatsoever.

I’ve already mentioned that the title of your page will have an effect. It’s also
very likely that the description does too.

But that doesn’t mean that your metatags are completely irrelevant when it
comes to AdSense. They aren’t. They’re only seem to be irrelevant when it
comes to serving ads; they still play a role in search engine optimization and
getting your site indexed faster.
