No, and that’s a good thing. Google itself warns business owners to beware of SEO agencies that guarantee specific ranking results. SEOs that promise guaranteed results–or better yet, guaranteed and fast results–are probably relying on either risky black-hat techniques or sneaky loopholes to deliver on that promise (like promising first page results with one keyword, but the catch is they get to choose the keyword, not you).
There are plenty of reasons why guaranteeing ranking results is a bad idea, including the baseline instability of rankings in general (based on location, personal account info, etc.). But the real truth is that the primary metric of successful SEO is traffic, not search rank. Moving your company up the search results for high value keywords is certainly an important tool to increase traffic, but it shouldn’t be the end goal in and of itself. We can confidently state that our expert advice will increase overall search traffic to your site, which is much more valuable.
