How Many SEO Keywords Should a Page Really Target?
Here’s what we recommend: pick just one primary keyword and enough secondary keywords to cover a given topic in full.
In the rest of the article, I’ll explain why and how.
Going forward, we’ll differentiate between two kinds of keywords.Â
The primary keyword, also called the target keyword, is the main topic of a page. It’s also the single keyword to optimize a page for.Â
Secondary keywords are any keywords closely related to the primary keyword that you’re targeting with your page.Â
Synonyms, subtopics, and long-tail keyword variations can be considered secondary keywords. But the best use of secondary keywords for SEO is as relevant subtopics—this is what I’ll focus on in this article.Â
So to sum up the difference, if the primary keyword is the topic of the book, you can use secondary keywords as subtopics.Â
