Hi guys, adwords question here:

Investor Carrot recommends that I use long-tail keyword phrases. Well, maybe they made that advice before Google made some changes? Because all of my "long" keywords are disapproved for being too low search volume. Keywords like Sell My house as is Dallas, Sell my probate house dallas, sell my inherited house dallas. Also, I made these phrases exact match. 

I don't think those phrases are even that long or specific. I was excited about this strategy because I wanted to save money. I don't need that many leads--in fact, just one lead a time is fine. And so having just a few leads that would have very good conversion sounded perfect. The theory is that long-tail searchers are going to have higher conversion because if they're typing something that specific, then they are serious about finding a solution. 

Why does google even care? If no one is searching for my phrases, then that is my problem, not theirs. If no one searches for them, then the ads will never show up, and that is my problem. I really don't understand it. 

What should I do? Phrases like We buy houses Dallas has a recommended bid of $47!! And then if you use Dallas county as the location, then it becomes $97!!! That is just absurdly far out of my budget. 

Thank you for any help.
