RTA Labels and Google...?
 

can having an RTA label / meta tag affect your page rank in a bad way?

Interesting question. Will hang around for the answer

I haven't noticed any penalty from Google using the RTA label. I have it on every single adult site I publish and have since they started.

I have it on my site as well, and traffic is well. The only downside (it's more of a good thing!) is that users with Internet filtering programs can't visit your site because of the meta tag.

I don't think so... but maybe there is a SEO expert that can answer this

No penalty. Tested and verified.
