I'm a bit confused, and these questions might be basic, but I can't find an answer. 1. When we talk about keyword density and usage, is that exact match only? If my main keyword is "best microwave ovens", but I also wish to target "microwave oven best" and "the greatest microwave oven". One of the secondary keywords is the same as the main one, but with singular instead of plural and the words re-ordered, and the other one is also the same, but using synonyms instead. Say you wanted to include all of these keywords on the same page, would you try writing 1% keyword density for each of these three? My guess is no, but then would you do 1% keyword density for the main keyword and then just include the other two somewhere in the article? Or would the two secondary keywords be included in the ranking automatically when just using the main one in the article, because they are so closely related? The last thing I can think of is to have a 1% keyword density of all these three combined? Please don't get hung up on the "1%" as this is just an example to illustrate what I mean. 2. How do you use awkward keywords in h1 page titles? Say your main keyword for the article is "tractor pedal for wife", would you try using this exact phrase in your h1 title? Or would it still work just as good if adding for example "best tractor pedal for your wife". The exact match keyword is then no longer completely connected in successive order, but separated by one word in between. 3. Does singular and plural of the same keyword count together for the density? For example, would 1% of "tractor shoes" and 1% "tractor shoe" add up as 2% of this keyword, or count as separate?
