When compting the keyword density on your text, do you also count approximations or just exact matches?
For example if I' targeting the keyword: "chocolate cheesecakes"
but in my text I use "chocolate cheese cake" and "chocolate cheesecake" interchangeably, will the first variation also be considered for keyword density, or just the exact match?
I've done about 5 inconclusive experiments regarding this topic, and I haven't been able to find the right answer on the internet.
I'm not doing SEO for Google, but for specialized search engines (e-commerce) that do take in consideration keyword density to position results.
