Businesses pay an SEO agency to maximize the ROI of their marketing campaigns. One way they do this is by engaging with SEO services (avoiding penalties such as Google Panda). An SEO company can improve your ROI by thinking like a business and being in tune with what people search for and what people want to buy. This engagement can even lead to more qualified leads, increased conversions per visitor, higher conversion rates, lower bounce rates, better rankings on the first page of Google- all of which result in a high rate of return.
