What is Keywords Everywhere and is it free?

Keywords Everywhere adds search volume, CPC and related keyword data directly inside Google search results and other supported sites. It is a paid tool with usage-based credits rather than a free extension.

It helps. Grammarly checks grammar, spelling and tone as you write ad copy, emails or landing pages directly in the browser, which catches mistakes before content is published or sent.

Are these marketing extensions safe to use with client campaigns?

Most read page content or your own typing rather than sending client data elsewhere, but check each extension's privacy policy, especially for tools like Keywords Everywhere that require an account and credits.

Can I check on-page SEO without an extension?

You can manually inspect a page's source code for titles, meta tags and headings, but Detailed SEO Extension does this in one click and presents it more clearly for a quick pre-publish check.

Do these Chrome extensions for marketers work in Edge?

Most, including Wappalyzer, GoFullPage and Grammarly, are Chromium extensions and install in Microsoft Edge the same way as in Chrome. Check each store listing to confirm.
