SEO work involves repeatedly checking the same on-page elements and researching the same kinds of keyword data, often across dozens of pages a day. These two extensions cover the most common checks: a fast on-page audit for any page you're viewing, and search volume and CPC data layered directly into Google's own results.
One-click on-page audits
Detailed SEO Extension shows a page's title tag, meta description, headings, canonical tag and other on-page elements as soon as you click its icon, without needing to view source or open a separate crawler. It suits a quick pre-publish check or a fast audit while reviewing a client's existing pages.
Keyword data inside Google search
Keywords Everywhere adds search volume, CPC and competition data directly next to Google search results and on other supported sites, which speeds up keyword research since you don't need to copy terms into a separate tool. It runs on a paid, credit-based model rather than a free unlimited tier.
Combining audits with keyword research
Using an on-page audit extension alongside a keyword data extension covers most day-to-day SEO checks: confirming a page's title and headings match its target keyword, then checking that keyword's estimated volume and competition without leaving the search results page you're already looking at.
