By definition, Rank Tracker's Keyword Difficulty metric shows how hard it's going to be to rank in top 10 results for any given keyword in Google or any localized versions of your target search engine.
The algorithm behind the Keyword SEO Difficulty value is dead simple. Basically, the keyword tool analyzes top 10 ranking pages for a certain keyword according to a wealth of important SEO metrics like:
A competitive keyword with high ranking difficulty may take years to rank in organic search. Measure Keyword Difficulty scores in combination with Search Volume metrics, and you will find keywords that have the highest chances of bringing you tons of organic traffic and don't require much optimization effort to rank for. And of course, Rank Tracker is the best of free SEO tools for estimating your traffic potential.
As a matter of fact, keywords with a score below 60 are the most difficult to find but the easiest to rank for. The lucky finds are low-competition keywords with considerable search volume. They become perfect keywords to optimize your pages for.
You may also have a look at KEI, visibility, and CPC parameters for a deeper analysis. The most typical picture is that high-volume keywords have higher competition. To improve the keyword rankings for them, you will need great content plus strong domain authority. This will require much on-page SEO in combination with link building from high-quality domains.
Keywords with low search volume are usually long-tail keywords that will be easier to rank for. They are less effective in terms of bringing much traffic to your site. However, you will need them to kick off and build up your domain authority. Besides, long-tail keywords enjoy a higher click-through rate from organic search.
Keyword SEO Difficulty is the very first parameter to look at when comparing your pages to best-performing competitor domains. Now Rank Tracker lets you compare your top 10 ranking competitors' pages for every SEO keyword.
You will get an instant overview of the keyword competition, with domain authority for the ranking pages, and the strength of their link profile. Such domain rating estimates how much on-page and link building effort it will take to occupy a position amidst the top 10 ranking domains.
If you've just collected a large number of new keyword suggestions and want to get an accurate Keyword Difficulty score for all of them in a bulk, there's good news for you. With Rank Tracker, you can check and compare the difficulty index of the whole keyword list. This feature is especially useful for those who carry out keyword research and have to deal with a large amount of data.
Being an SEO, the last thing you probably want is to drown under a huge number of rubbishy keywords that have no chance to bring traffic to your site and are too hard to rank for. So the only right solution is to filter them with an appropriate SEO difficulty index, prioritizing keywords that have the potential to maximize your SEO results and can be worked on.
With super fast-changing competition landscapes, Keyword Difficulty is the kind of metric that needs to be constantly monitored. The good news is, Rank Tracker can get your scores calculated (together with a number of other SEO stats in bulk) completely on autopilot. Note that the automated tasks are supported in the Enterprise version, but there is always a free trial to test it.
