SEOquake Review 2026: Honest Pros, Cons and Pricing

SEOquake is a free browser extension built and maintained by the Semrush team. it runs in Chrome, Firefox, and Opera and overlays SEO metrics directly onto search engine results pages. there are no paid tiers, no trial periods, no credit limits. you install it, connect it to a Semrush account if you want deeper data, and it starts surfacing domain authority, backlink counts, indexed page estimates, and traffic signals right inside Google or Bing.

the product has been around since roughly 2008, which makes it ancient by software standards. its longevity is partly explained by how narrow the problem it solves actually is: give SEOs a quick-read dashboard inside SERPs without forcing them to open a separate tool. it targets freelancers, in-house SEOs doing competitive research at scale, and anyone who wants to qualify pages while browsing rather than copy-pasting URLs into a separate app.

the headline verdict is this: SEOquake is probably the best free SERP overlay available, and it does its specific job well. but it is not an all-in-one SEO platform. if you are hunting for a rank tracker, a site audit crawler, or a keyword database with filter controls, you will need something else alongside it or instead of it. for operators who already pay for Semrush and want a lightweight companion in the browser, it’s a no-brainer. for everyone else, the gaps are real.

what SEOquake actually does

the core feature is the SERP overlay. when you run a search on Google, Yahoo, or Bing, SEOquake injects a row of metrics beneath each organic result: Semrush rank, estimated organic traffic, number of backlinks, number of indexed pages, and a few configurable extras. you can toggle which parameters show up. you can sort SERP results by any of these columns. for competitive research on a new niche, this saves the manual step of checking each URL individually.

the SEO bar is a persistent toolbar that activates on any page you visit. it shows the same core metrics for whatever domain you’re currently on, along with a quick count of internal and external links. click through to the “page info” panel and you get a more structured breakdown: meta title, meta description, headers in order, canonical tag, schema presence, og tags, and a basic robots/index status check. this is genuinely useful for doing on-site audits across competitor pages one at a time.

the keyword density tool scans the visible text on any page and ranks terms by frequency. it isn’t particularly sophisticated but it gives a fast signal when you’re evaluating whether a page has its target term appropriately distributed or stuffed. you can export the density report to CSV.

the comparison feature lets you stack up to 10 URLs side by side using the same Semrush-sourced metrics. for SERP snapshots during a pitch or a competitive audit, the ability to export this comparison to a clean CSV in one click is one of the more practical things SEOquake does.

SEOquake does not have a rank tracker. it does not crawl your site. it has no keyword research database with filters, search volume, or difficulty scores on its own. it has no backlink explorer beyond showing a count. it has no API. what you get is a browser-layer inspection tool, nothing more and nothing less.

pricing

SEOquake is free, as of 2026, with no premium tier. the extension itself costs nothing. there are no data credits, no seat limits, and no usage throttle imposed by SEOquake independently.

the important caveat: the underlying data comes from Semrush. if you run SEOquake without a Semrush account, you still get metrics but they are capped. the more detailed competitive data, traffic estimates, and some advanced parameters are only fully visible when the extension is authenticated with an active Semrush account. Semrush plans start at roughly $139.95 per month (as of 2026) for the Pro tier. so while SEOquake itself is free, squeezing its full value out of it has a cost attached elsewhere.

for operators who already pay for Semrush at any level, SEOquake is a pure bonus that adds no incremental cost.

what works

it’s actually free. not free-with-asterisks like most “freemium” tools. the extension installs, it works, it surfaces data. if you do competitor research in Google and want an at-a-glance read on domain authority and link counts without opening a second tab, SEOquake delivers that with zero friction.

SERP overlays save real time. the ability to scan ten organic results at once and compare backlink counts, traffic estimates, and indexation numbers without leaving the results page is where SEOquake earns its keep. for niche research workflows where you’re qualifying fifty SERPs a day, this matters.

the on-page audit is solid for a free tool. the page diagnosis panel catches the basics: missing meta descriptions, duplicate titles, header structure, canonical status. it’s not a Screaming Frog crawl, but for a quick one-page check on a competitor’s landing page, it’s faster than loading Chrome DevTools.

export is clean. the CSV exports for SERP comparisons and keyword density reports are formatted properly and open without cleanup in Excel or Google Sheets. this sounds trivial but a lot of free tools produce exports that require reformatting before they’re usable.

Semrush data infrastructure. the underlying data source is one of the larger SEO databases available. for high-traffic or well-indexed domains, the traffic and backlink estimates are in the right ballpark. you’re not working from a thin or obscure data set.

what doesn’t

no rank tracker. this is the single biggest gap. SEOquake tells you where a URL ranks right now in a SERP you happen to be looking at. it does not track your rankings over time, does not send alerts on movement, and does not let you set up a keyword list to monitor. for any operator running a site, this means you still need a dedicated rank tracker regardless of whether you use SEOquake.

backlink data lags. the backlink counts shown are from Semrush’s index, which historically updates on a multi-week cycle for lower-profile domains. if you’ve just built a batch of links and want to verify pickup, SEOquake is not the right check. it’s a number that tells you roughly where a domain stood a few weeks ago.

thin data on small or new domains. for domains with limited traffic or a short history in the Semrush index, the metrics often come back blank or show zeroes that clearly aren’t accurate. this is a known Semrush limitation that SEOquake inherits. if your niche is dominated by smaller sites, the competitive data loses accuracy fast.

no API, no automation. there is no way to pull SEOquake data programmatically. you cannot script SERP snapshots, feed the output into a database, or integrate it with any other workflow tool. for operators who run at scale, this makes SEOquake useful only for manual spot checks. anything systematic requires a paid platform with API access.

zero site crawl. common complaints in SEO communities point out that SEOquake markets itself adjacent to full SEO suites but can’t actually crawl a site. you get one page at a time in the browser. there is no way to scan a thousand-page site for broken links, duplicate content, or crawl depth issues.

who should buy / who should skip

good fit:

• SEOs who already pay for Semrush and want the SERP overlay without logging in to the web app constantly
• freelancers doing competitive research inside Google who want a faster qualification loop
• content teams that want a quick on-page check before publishing or updating a page
• anyone who wants a free second opinion on a domain’s rough traffic and authority while browsing

not a good fit:

• operators who need a rank tracker with historical data and keyword lists; look elsewhere
• technical SEO specialists who need crawl-based audits; SEOquake won’t replace Screaming Frog or a site audit module
• agencies or teams that need API access to pull data into dashboards or reporting pipelines
• operators focused on affiliate or lead-gen sites with newer or smaller domains where Semrush data is thin

alternatives to consider

Semrush is the obvious upgrade path. if you are already using SEOquake and finding yourself wishing it did more, paying for the full Semrush platform gets you rank tracking, site audit, keyword research, and backlink analysis on top of the same underlying data. it is expensive, but it is a complete workflow rather than a browser layer.

Ahrefs SEO Toolbar is the closest direct competitor. it overlays Ahrefs data into SERPs instead of Semrush data. if your primary backlink research tool is Ahrefs, the toolbar is more coherent than mixing Ahrefs with SEOquake’s Semrush numbers.

MozBar covers the same browser-extension niche using Moz’s Domain Authority and Page Authority scores. the DA/PA metrics are widely cited in outreach and link-building contexts, which makes MozBar specifically useful for prospecting. the free tier is more restricted than SEOquake’s.

verdict

SEOquake is a genuinely useful free tool for a specific, limited job: getting a fast read on SERP competition without leaving the browser. it does that job better than most alternatives at the same price point. the gaps are real and documented: no rank tracker, no crawl, no API, thin data on smaller sites. treat it as a supplementary layer on top of a paid platform, not a standalone solution, and it earns its place in the workflow. if you are expecting it to replace a full SEO suite, it won’t.
