Jaaxy analyzes two metric variants to determine the SEO quality of your chosen keyword. The first one is traffic, while the second one is competition. It will then give you a score from 1 – 100. When the number is high, it means that other sites you are competing with have poorly optimized their websites, and you’ll get an acceptable number of visitors. Anything over 80 is really good.
However, this does not mean you cannot topple them. It just takes more of an effort in terms of content as your page has to build the trust. That is why you will see the "Google dance" happening for fresh content from a site that is not yet trusted or is not very authoritative. Google gives your page a chance and measures user click-throughs when it pushes you to certain spots in the SERPs and then measures user engagement levels when the traffic hit your site through those positions in the SERPs.
