So I always thought by KW density was the number of times the Primary/Focus KWs repeated divided by the total word count.
WHAT I`VE BEEN DOING:
So with that understanding, I`ve been using similar to relevant KWs as secondary KWs for my articles and pages.
1. Now is this considered to be KW dumping if I use 100s of KWs for a page, but they aren`t all the same and they all translate directly/partially to the page topic?
2. Out of all the similar KWs, I pick the one with the highest search volume & relevancy to be the Primary KW.
Is the above an okay approach or should I limit myself to 3-5 LSIs and Secondary KWs?
What is the main criteria for picking the Primary/Focus KW?
