I did this for several companies as a freelancer and improved their page ranking!
The Problem
For many companies, there is a lot of competition for the first page of Google search results. Usually, common words are very competitive, while niche words and phrases don't get a lot of attention from potential clients.
Many companies also don't invest in proper SEO, resulting in lower page rankings and thus, lower profits.
The Solution
Every company requires unique solutions. For many smaller companies, I had to focus on niche phrases and local SEO strategy development so their business could produce consistent profit. After that, I went for higher competitive phrases that similar companies used. By publishing good, creative, and insightful content, their rankings rose higher, resulting in more revenue!
