We offer quality services. However, we want to be honest with our customers and don’t offer unrealistic guarantees.
In the real world there is uncertainty about the future. You can’t predict what will happen, despite of (mostly) deterministic laws of physics.
Since we make hard work to improve the web presence of our customers and our profit margin is not big enough to deal with non-paying customers, we don’t offer “positive ROI” (“money back”) guarantee.
Be cautious when searching for SEO services, because some Internet marketing companies offer unrealistic guarantees, such as №1 ranking on search engines, but don’t specify on which search engines (so Google may not be one of them).
