Well, first of all, it's a good idea to realize that in-house employees are quite expensive to keep on the payroll-especially when it comes to expert level technical gurus-the kind of people that know SEO inside and out. Even though they still might help you make a profit through your search engine optimization efforts, just think of how much a year's worth of salary, benefits, and other additional employee costs will set you back here. The bottom line is it's just not cheap to have full-time SEO employees on staff.
