About keyword research...

You might get it wrong. For example if prevoius month was 230 millions searches for football and merely 5 milions for footballs it would be better to optimize for football. Now, even if you got worse position it would generate you more traffic since it's over 45 times more searches. Unless you fear you have no chance to show anywhere close enough to gather traffic because competition is too strong for you.
