Full SEO platforms are useful for ongoing tracking, but many day-to-day checks don't need one: confirming a page's title tag, checking heading structure, or glancing at search volume for a keyword you just typed into Google. SEO extensions handle these smaller, faster checks from the toolbar.
Run a quick on-page SEO audit
Detailed SEO Extension checks a page's title, meta description, headings, canonical tag, hreflang and links, then flags common issues, all in one click. It's built for fast checks while browsing rather than an ongoing crawl, which makes it useful during content reviews or when auditing a page a client just published.
See keyword search volume inside Google
Keywords Everywhere is a paid tool that overlays search volume, cost-per-click and competition data directly on Google search results and other supported sites. This saves you from copying keywords into a separate research tool every time you want a quick volume check while browsing or researching content ideas.
Free vs paid SEO extensions
Free extensions like Detailed SEO Extension cover on-page audits well because that data comes from the page itself. Keyword volume and competition data, by contrast, comes from a paid API behind tools like Keywords Everywhere, which is why volume-focused extensions typically require a paid credit balance.
