Maybe this question can't be answered, but I had to ask just in case. What is highest CPC search term on Adwords? (*And therefore the most profitable keyword(s) to write for on a niche site?) For example, "insurance" is OK, but "auto insurance price quotes" has a much higher CPC. I discovered this by spot-checking. Is there a way to reverse engineer the Keyword Planner, or use any other online tools, to figure out what the highest CPCs are right now? *Is this assumption even correct? I am starting from scratch on a new niche blog and want to choose the most valuable niche possible. My traffic source is not Google searches, so it doesn't bother me if the related search results are already saturated.
