The problem is that about 90% of the work is handed off to the site owner. Basically, the owner is handed a list of sites that require subscriptions and offer link exchanges. Furthermore, the "SEO company" may perform some very minor work to the site but most of the time the work is performed by the owner or the site's webmaster.
While there are legitimate companies that, indeed, help a site increase its rankings, the majority are, unfortunately, pretenders to the throne. Also, it takes months for a site to achieve good rankings if and only if SEO has been performed correctly.
DBDConnect takes SEO very seriously because we realize we are dealing with a company's livelihood. For a fair, honest, and complementary evaluation of your site contact us today. We never accept any SEO project unless we are confident we can achieve 100% of our goals. In addition, we perform complementary SEO on new website projects.
