Forum Moderators: open
*Disclaimer: Obviously I don't work for Google. Just got this idea while watching all of us go bonkers wondering when the next dance will start.*
I, personally, think that Google should be more open about it's crawler dates (deep crawl) and the estimated date of the dance in general.
There may perhaps be a value add they could 'sell' that would give you access to detailed information about your site(s) -- keywords, heads-up on 'issues' etc. that could be paid for by a modest yearly fee.
I would love to know what is and is not being regarded as relivant in my sites by Google. Perhaps that's something they can do (and automate!)
