Keyword Density Alerts *

With keyword density alerts, you can automatically monitor your website's pages to ensure your copy remains as search engine friendly as possible.

Every day, Readable.io will automatically fetch your alert URLs. It will measure the keyword density for each of your words and phrases, and email you if the density goes below your lower limit, or above your upper limit.
