Most of the time, more than you could possibly dream. Many of our clients increased their online sales by 1000 percent in just 16 months, resulting in a ROI of more than 20 times. The real benefit of SEO is that the leads and traffic you generate last for a very long period. For instance, our SEO experts ran the numbers, and they found that a plumber in New Jersey might make over 25X their investment back in profit over the next 12 months via a unique 12-month SEO strategy. But after a year, when they stop investing in SEO, their ROI increases by up to 50 times!
