Sales impact
How much a keyword matters for your sales, from search volume and relevance. High where both are high; small long-tail keywords still count, just less.
Sales impact combines the two things that decide what a keyword is worth to you: how often shoppers search for it each month, and how relevant it is, meaning how much of the top 10 organic results are products like yours. A keyword with many searches and a top 10 full of products like yours scores high. A big keyword with only some products like yours stays in the middle. A small long-tail keyword where everything fits scores low, but never zero, because many small keywords together sell too. A keyword where no product like yours makes the top 10 has no sales impact. Search volume counts on a log scale: going from 1,000 to 10,000 searches adds as much as going from 10,000 to 100,000. The value is the same in Research and in Tracking, whatever other keywords you have.
