Think of investing in SEO like buying a nice new pair of leather shoes. The largest investment is the pair of shoes (like the SEO setup fee), but the monthly management is like polishing and repairing the shoe. By taking care of your shoe, they stay useful and nice.
Once you pay the initial setup fee for SEO, you will (and should) be interested in seeing improvements in your company’s overall visibility on the web. Ongoing SEO requires individual attention to each site. It includes adjusting efforts over time, continuing to make site changes, building links, and adjusting keywords based on past search results and statistics.
SEO management allows your web presence and availability to grow over time. After the initial cost, improvements from monthly service can contribute to an ongoing return on investment. Search engines and competitors will continually change, so monthly maintenance ensures a competitive edge.
