As POKER is one of the most sought-after keywords EVER, and considering the thousands of poker sites in English that were set up before you, I see 2 ways for you to generate traffic:
1) get more original content and update it quicker than the big poker portals (not very likely…)
2) Catch a niche.
Your meta KWs are pretty generic. Why would Google suggest you over thousands of more experienced sites with the same KWs?
The only way I see a NEW poker affiliate getting organic traffic is by catching long-tail or unique KWs that have little competition.
You may need to build new sites for this purpose….
Some examples and variations: “holdem murder”, “Uzbek poker”, “grabbing the nutz” (I should copyright that one), “Omaha domination”…
I’m just making stuff up. To know which KWs to optimize for, you should hit the poker forums and poker operator chats and try to catch popular phrases not used by too many of your competitors.
Good luck!
