What is the 80/20 rule for SEO?

The 80/20 rule in SEO means roughly 80% of your traffic or rankings usually come from about 20% of your pages or keywords. A handful of pages carry most of the weight, and the rest support them.

In practice, that means finding which pages already pull traffic and doubling down there, rather than spreading equal effort across every page on the site.

This is sometimes called the 80/20 rule, the Pareto principle, or just '80 20 SEO,' but it's the same idea: a small share of your pages usually drive most of your results.
