About Spark SEO by seoClarity
Spark SEO is seoClarity's browser plugin that puts SEO data for any webpage a click away. For the page you are viewing it shows the keywords it ranks for, checks key on-page elements, identifies technical issues on the fly, reveals backlinks, surfaces the key topic and reports Core Web Vitals. It pairs with seoClarity's Content Optimizer and is built for everyone in an enterprise, from content writers to technical SEOs. After years in development it is now freely available to anyone, so you do not need a seoClarity account to try it. Results appear in the browser for the page you are on, so a writer can check a draft's topic while a technical SEO checks Core Web Vitals, with no separate dashboard.
