blannyjeanna,
I guess the question that really must be asked is: are you advertising to English-speaking people? I am not poking fun. I know you're not a native English speaker, but if I came onto a page and it was written like your posts are written, I would probably leave immediately.
If that is the case, you may want to look into hiring a copywriter.
In terms of getting your site to #3 for "bingo", What country are your offers for? Take into consideration that the search volume is high for bingo, but much higher in the UK than in the US. If you're advertising a word that might be more commonly used in a foreign country, but aren't getting leads, it might be because your offers are US only.
Just some things to think about.
