Keyword Density: This is how often a keyword appears in a text. For example, if a word appears ten times in a 100-word text, its keyword density is 10%. But remember, using a keyword too much can hurt your website's search engine ranking.

Keyword Consistency: This is about using your keyword in different parts of your webpage, like the title, headings, and body text. It helps search engines understand what your page is about. But just like with keyword density, using a keyword too much can be harmful.

So, keyword density and consistency help your webpage appear in search results, but only when you balance them with making your content valuable and interesting to people.
