I don’t know why you would think Lycos somehow treats poker differently than other terms, but the idea is absurd anyway. How are they supposed to know that “omaha big blind play” is a poker term?
For another source, Rank Pulse tracks both online poker and texas holdem in its top 1000, in addition to poker (and betting and gambling and…).
The point again is that this is not a business of one term, even the best one.
I think a problem here is expectations. 1000 visitors a day to one site for one term is huge. Overture bids for “poker” ran over $22 a click at one point, and were about twelve bucks when they stopped. That’s over $10k a day from one term, for one site. (1000 is low anyway but that hardly matters.) How many humans a day would you think would take the time to search for poker or whatever in a day? How many people does anybody think their website should attract, for free, from search engines in a day? (What would you expect???) You can get a helluva lot, but if you are thinking of a million people a day, you are crocked. And if you are thinking in terms of one search word, then you are crocked too. Thousands of people from thousands of terms is possible, but not if you just think of one term.
