Buyer's guide

How to choose seo chrome extensions

An SEO extension reads the page you are on, or the results page you are looking at, and shows the data without opening another tool. The list starts with products that are extensions first. Below them are SEO platforms that ship an extension alongside their web app, where the extension is usually a window into the paid account.

Free on-page checkers

For a quick look at a page's title, meta description, canonical, robots directives, headings and structured data, three extensions cost nothing. Detailed SEO Extension and SEO Pro Extension are free for Chrome and Firefox, with no paid tier. SEOquake runs its core reports without an account, and a free Semrush account adds Authority Score and referring domains. These cover most day-to-day checks.

Extensions that pull data from a paid index

Link and authority metrics come from a vendor's own crawler, so the extension is free and the numbers behind it often are not. MozBar shows on-page elements with no account at all. Its premium features come with a Moz Pro plan, which starts at $99 a month. The Ahrefs SEO Toolbar does on-page and redirect checks for free, adds Domain Rating and URL Rating with a free sign-in, and shows full Ahrefs metrics on a paid plan from $29 a month. Keywords Everywhere puts search volume, CPC and competition next to Google, YouTube and Amazon results on a credit plan. SEO Minion, which used to be free, now needs a Keywords Everywhere Silver plan, $14 a month billed yearly.

Beyond SEO

Wappalyzer identifies the CMS, frameworks, analytics and ecommerce stack a site runs on. That is useful for audits and competitor research. The extension is free, and a free account gives 50 technology lookups a month.

What to check before you install one

Which browsers it runs in. Most support Chrome and Firefox. Edge and Safari support varies, and each tool page lists the platforms the vendor names.
What needs an account. Free extensions often show the basics and lock link metrics behind a sign-in or a plan.
When it was last updated. A stale extension can break when Google changes its results page. Check the store listing's last-updated date before you rely on one.
What it can read. An extension that reads every page you visit sees a lot. Install the ones you use and remove the rest.
