The keyword difficulty tool is a keyword analyzer that helps you to find the keywords that will work best for your SEO and SEM campaigns.
The higher the score, the more difficult it is to get high rankings for that keyword. If you have a new website, it's usually better to start with keywords that are less difficult.
Prioritize your keywords based on how much effort it will take to rank for them vs. how much potential traffic they can bring. Focus on the best keywords and save a lot of time and money.
The keyword suggestion tool in SEOprofiler shows a competition value. That competition value shows you how many other websites advertise for a keyword.
These two values enable you to find the best keywords for both SEO (search engine optimization) and SEM (search engine marketing).
