FAQ
Questions, answered.
How is the score worked out?
From the keyword itself: short, broad “head” terms and words with buying intent (best, buy, price) are fought over by big sites, while long, specific or local phrases are easier. It is an estimate — it does not measure the backlinks of the pages that currently rank.
How accurate is it?
Good enough to sort a list into easy, medium and hard before you invest time. For a final decision, search the keyword and look at who ranks on page one.
Is my keyword list stored?
No. The estimate is calculated in your browser.
