correlation
Relevance not only considers the optimization effect, but also aims at achieving a better user experience. Our headline writing must be closely related to the theme of the website.
terse
When writing a title, we need to focus on a theme. Too long a title will dilute the keyword density.
Keyword frequency
Personally, I think it is better for the main keyword to appear 2-3 times in the title, and it is better for the secondary keyword to appear once.
Keyword position
The higher the keyword, the higher the weight given by the search engine, so when combining a title, the core keyword can lean forward.
segregator
Use vertical bar |, space, comma or horizontal separator to separate and combine the main and auxiliary keywords in the title content to achieve the best theme effect.
