What's the use of this tool? When product layout keywords, you can use this tool to query whether the keywords have other names, and find products that have a large search volume but are not so competitive. As shown in the figure below, we take the word "customize" as an example, we can find the following similar words. The darker the color, the more similar the display.
It's a bit like an introduction to a word in a dictionary. I usually use this tool to write articles that are semantically related. For example, if the topic of an article is about weight loss, then I actually need to add "exercise" to the article. The words "oatmeal" and "calories" help search engines to understand the content of this article
