SEO Services that generate a true return on your investment must deliver two critical results and they must do so consistently.  They must deliver Page 1 rankings and a measurable and attributable increase in traffic. Doing one without the other delivers only half the job and will likely leave you well short of any reasonable ROI targets.
What you spend on SEO services must be considered an investment, not an expense.  If it\’s an expense there are better ways to spend your hard earned money. As an investment, the amount you commit must generate a superior return when compared to other areas you could be investing in.  If your SEO Service provider doesn\’t understand this change them now!
