Let's compare SEO to fixing a car. If you have the time, know-how, and tools needed to do the job, then you can certainly do it yourself. But many people choose to hire mechanics instead, because they trust the expertise and long practice of those professionals. Similarly, businesses often hire companies like Wpromote to handle their SEO efforts due to the amount of knowledge required to effectively run an SEO campaign, not to mention the time required to do so. SEO is also ever-changing, and keeping up with the shifts in algorithms prevents the best practices of yesterday from becoming the cause of penalties tomorrow. Running a business is a full-time job, and SEO is no different. Oftentimes, business owners find that they are better off concentrating their efforts on growing and managing their company, and leaving tasks like SEO and web design to those who specialize in providing these services.
