We are using the example of "Plumber New York" in this case.
The values displayed under the "Rank" column is based on our internal algorithm. It calculates a rank based on how long the keyword is and how similar it is to your main keyword. In this case, if you want to choose the best potential keywords, you have to exercise the rank factor , the search results/YT competing videos and some basic common sense too.
By looking at the results, you can see that these keywords are most suited to be used:
- licensed plumber new york city,
- master plumber new york,
- emergency plumber new york city,
- licensed plumber in brooklyn
- plumber in new york
These are great keywords because they are long tail keywords (3 or more words), rank is not too high nor too low (something among the middle), and the search results/YT competing videos which represents competitiveness is reasonable.
FYI if the search results/YT competing videos is very high which in this case more then 500,000 then it is bad choice as you will lose against those highly competitive videos. But there are other keywords where the "search results/YT competing videos" shows lower and more reasonable values 146 for "master plumber new york" etc. Clearly this shows this is a more viable choice to make.
In summary - Use the data presented under "Rank" for relevancy guidance, "search results/YT competing videos" for competition guidance purposes. Lastly - exercise common sense to see the keyword itself is suitable to be used in your video title.
Just because a keyword has a low Rank does not mean it's not a good keyword. For example, it can be a long tail keyword that is not strictly related to the main keyword. That means it can be a good keyword, but the rank is not good because it's not similar to the main keyword.
