We produce this table by checking your campaign keywords only in your primary search engine and seeing which pages are returned first.
The first page it lists is normally your home page. It will be unusual if this is not the case and may point to an issue with your home page which may need to be looked at.
If your critical site pages like e-commerce pages or key product or service pages are not listed in the upper echelons then you should look at your site navigation and structure, and your internal link structure to see what can be done to improve the profile of this page.
