There are many ways to look for a good kw which means a keyword that easy to rank on the first page of Google or even rank on top 3 or #1. Many expertize in SEO referring newbie to look at the first 10 sites on first page of Google. Forget about numbers of intitle, alltitle, "keyword", keyword when search in google bar. Just look at 10 sites of PR, age, Title, Description, keyword in domain, SEMOZ inbound back links.
I recommended a good kw may have: at least 3 pr0 sites and max pr4 all 10 sites, age = not really matter, max 3 exact titles and descriptions in 10 sites, max 2 sites exact keyword in domain, at least 3 sites 10 BLs below. You can download SEOquake to see manually on Google search page.
These keywords are not really easy to find but not impossible and also it usually has low exact Local search term there you need to consider depending on your pockets money and time to chase small hanging fruits or big lots of fruits but high SEO competition. One more point, if you used the site for adsense remember to look at least medium Advertiser competition.
