SEOTesting

On-page SEO information for the page you are viewing, plus test details from SEOTesting.com, arrive through this Chrome extension. It shows current page queries and the status of any test running on that page, so you can read the numbers without switching tabs. The test data requires a SEOTesting account. It is aimed at SEOs who run split tests on their pages and want quick context on queries and test progress as they browse their own pages, instead of jumping between the reporting dashboard and the live URL. Its description lists on-page SEO details and test information as the two things it shows, and nothing else. Anyone without that account will see only the on-page details, so it is best treated as a companion to the paid service.
