When people search, they aim to answer a question. They just search in the truncated version of that question. Keyword research is largely data-driven around the popularity of the terms in their question. Keyword research in semantic search will have to focus on what that person actually means when searching for that keyword.
For example: Yoga. What could people mean they search “yoga?”
What is yoga?
The different types of yoga
How to do different yoga positions
The best fit of yoga pants
Yoga exercise videos
The possibilities are endless. When you’re framing your content in a semantic search world, it has to be around answering the specific questions people have as it relates to that keyword. With every sentence you write, ask yourself: How does this answer the searcher’s question? You will have to focus on the natural language even if those users are still focusing on keywords.
