Chrome SEO extensions compared: SEOquake, SEO Minion, Detailed and Optia (2026)

Disclosure first: I built Optia, the fourth extension in this comparison. It is my product, it is the newest and smallest of the four by a wide margin, and I have described the other three the way their own listings describe them. Every figure below comes from each extension's Chrome Web Store listing or the maker's own site, read on October 22, 2026 and re-checked on October 31, 2026. The sources are listed at the end, with dates.

I wrote this because the question I get from small-business owners is rarely "which extension is the most powerful". It is "which one tells me what to fix on my own site without a week of reading". The answer depends on what you already pay for and how much interpretation you want to do yourself.

The short version

Prices and store figures as of October 31, 2026.

SEOquake: the audit and results-page overlay

SEOquake is Semrush's free extension. Its listing describes:

• On-page checks: title tag, meta description, headings, canonical tag, indexability and word count.
• A page-level audit covering content, mobile and technical issues.
• A SERP overlay that puts position numbers and Semrush metrics on the Google results page, plus an AI Overview source analysis.
• The SEObar toolbar for traffic and backlink metrics.
• Internal and external link analysis, including broken links.
• A keyword density report, side-by-side URL and domain comparison, and PDF and CSV export.

The core reports work without an account. An optional free Semrush account adds features such as Authority Score. Its last update was October 15, 2026, the most recent of the three extensions I did not build. It carries a 3.5 rating from 2.6K ratings.

Suits: someone who already thinks in Semrush numbers and wants them on the results page while searching, or who wants a full audit report to export.

SEO Minion: included with Keywords Everywhere

SEO Minion's listing describes:

• On-page analysis and broken link checking.
• A SERP preview and a Google search location simulator.
• An hreflang checker and structured data analysis.
• SERP data copying and downloading, HTML versus DOM comparison, and link highlighting.

On paper it lists checks the other three do not, such as the location simulator and the HTML versus DOM comparison.

The catch is in the listing itself: "SEO Minion is available only to customers of Keywords Everywhere's Silver or higher plan." Keywords Everywhere's pricing page puts Silver at $14 a month, billed annually, which is $168 a year. Its setup page says the Bronze plan and the free tier do not include it. There is nothing to buy separately. You buy Keywords Everywhere, and SEO Minion unlocks with the API key.

Two more facts from the listing: the last update was February 22, 2026, and the rating is 1.6 out of 5 from 797 ratings. The privacy section lists personally identifiable information and location as data the extension handles.

Suits: someone who already pays for Keywords Everywhere Silver or above. If you do, it is included and worth installing. If you do not, the alternatives section below maps its features to free tools.

Detailed SEO Extension: a quick read of a page

Detailed's extension does one thing and does it in a click: it shows what a page says to Google. The maker's page describes:

• An overview tab with page-level insights, including the X-Robots HTTP header and a sitemap quick link.
• A headings tab that indents the headings to show structure and copies them all to the clipboard.
• A links tab that flags nofollow and sponsored links, and an overview tab that exports every link on the page.
• An images tab that exports image URLs as a CSV.
• A schema tab that shows structured data, including hreflang views and hreflang status codes.
• An advanced tab that extracts People Also Asked questions from search results, switches the user agent so you can view a site as Googlebot, and adds site: searches.
• A right-click menu that opens the current page in Ahrefs, Moz, Majestic, Archive.org, SimilarWeb or Semrush.

The maker's page says "100% free" and "No upsells. No tracking." The store listing agrees on data: the developer states it will not collect or use your data. The store lists the developer as Ahrefs. The rating is 4.8 out of 5 from 233 ratings, with 600,000 users and an update on June 2, 2026. The maker's own page shows three different user counts, so I use the store's.

Suits: anyone who wants the facts of a page without a score or an opinion attached. It is the one I would hand a developer.

Optia: a score and a to-do list

Optia is mine, so weigh this section accordingly. The listing describes:

• A free on-page SEO checker with a 0 to 100 score.
• Keyword usage tracking.
• AI suggestions for the title, meta description, H2s and alt text.
• High and Medium priority labels.
• A side panel with light and dark themes.

The idea is simple. You type the keyword you want the page to rank for. The panel lists what is missing, High priority first, and drafts a title, meta description, H2 or alt text you can paste.

Pricing: the free tier includes 25 AI recommendations a month. Optia Pro is $5 a month or $50 a year with 1,000 recommendations a month, and it is billed through Stripe, not the Chrome Web Store. The checks themselves, the score and the priorities, do not use the AI quota.

The honest numbers: version 1.2.0, updated October 27, 2026, 9 users and one rating on the store as of October 31. It went live on the Chrome Web Store in August 2026. On data, the privacy section lists authentication information (for Pro sign-in), user activity and website content. The overview says only relevant page snippets are sent to the AI service, and only when you ask for a recommendation. Since version 1.2.0 it also sends one usage number at most once a day: how many pages you analyzed this month, tied to a random install ID rather than your name or account, with no URLs or page content. You can turn that off in Options. The source is public on GitHub.

Suits: a business owner or a freelance builder who wants a prioritized list and a draft to paste, rather than a set of reports to interpret. Not a fit if you want backlink metrics, SERP overlays or a full-site crawl; it looks at the page you are on.

If you are looking for an SEO Minion alternative

Map the features you used to the free tools:

• Broken links and link lists: Detailed's links tab flags nofollow and sponsored links, and its overview tab exports every link on the page; SEOquake's link analysis includes broken links.
• Structured data and hreflang: Detailed's schema tab shows both, including hreflang status codes.
• Keyword density and word count: SEOquake.
• A prioritized fix list with draft titles and descriptions: Optia.
• The SERP preview and the location simulator: none of the three replaces these exactly. For a snippet preview, the search results themselves are the test; for location, Google's own search settings cover most cases.

If you are looking for a SEOquake alternative

If the results-page overlay or the reliance on Semrush's metrics is the problem, Detailed gives you the page facts without the overlay. Optia gives you a score and a list without any third-party metrics. If what you want is the audit report, SEOquake is still the one of the four that produces it.

Which one for a small-business website

• One site, a handful of pages, and you want to know what to fix first: run Optia on each page, or run Detailed and work through my on-page SEO checklist. Detailed is free; Optia's checks and score are free, with 25 AI recommendations a month.
• You already pay for Keywords Everywhere Silver or above: SEO Minion is included, use it.
• You do SEO for clients and want Semrush numbers on the results page: SEOquake.
• You want someone else to do it: that is what my Baltimore SEO page is for, including the section on when you do not need it.

None of these replaces Google Search Console. The extensions tell you what a page says; Search Console tells you what Google did with it.

If you want to try mine, Optia is on the Chrome Web Store, and the Optia page has the demo video.

How I checked

Every figure in this post was read on October 22, 2026, and re-checked on October 31, 2026, from these pages:

• SEOquake: its Chrome Web Store listing (rating, users, version, update date, feature overview, privacy section).
• SEO Minion: its Chrome Web Store listing and the Keywords Everywhere pricing page and SEO Minion setup page for the plan requirement and prices.
• Detailed SEO Extension: its Chrome Web Store listing and detailed.com/extension for the feature list.
• Optia: its Chrome Web Store listing.

Store ratings, user counts and version numbers change. If a figure here no longer matches a listing, the listing is right and this post is out of date.
