So, When you do some keyword research with google adwords some keywords might have a high competition, some of them can be low. As far as I understand this reflects the bidding people put in for paid results, not organic results. I keep reading that when trying to choose for keywords, those with low competition are easier to rank for than those with high competition. But how do they relate? Intuitively I understand that when people are willing to pay a lot of money to use a certain keyword for CPC then that same keyword might also be desirable for organic search results improved with SEO. But is there a real quantitative relationship between competition and how easy you can get good rankings for keywords? Anyone got some numbers, correlations? Thanks!!
