On the left of the table you have the phrases for which people search on Google. Let your eyes wander to the other side of the table and you will see the conversion rate, and how many leads (or how much revenue for all you e-commerce bods) that phrase has driven for your business.

Looking at those top performing terms, you clearly deliver answers to the questions that your potential customer is asking. You might be able to improve that conversion ratio further - consider setting up specific Ad Groups with optimised Landing Pages for those terms which are already winning.
If there are search terms there which aren't turning into leads or revenue, but in your gut, you know they SHOULD be, then something's wrong with the journey your customer is taking on your website. You can try setting up optimised Ad Groups and Landing Pages for these too - it might fix stuff in the short term. It's also worth taking a critical look at your website, though. Get someone unconnected with your company to take a look, like a friend or family member. Or failing that, get it looked at by some professionals who have a monkey in their logo ;)
