Seoquake Firefox
Shows on-page SEO metrics and audit data for any page or search result you view, directly inside Firefox.
If you have ever treated its keyword density report as a ranking signal rather than a diagnostic hint, you already know the tool shows data, not causes.
Key points
- Use the SEO Audit feature for a quick technical check, but never rely on it as a full site crawl.
- Treat link counts and keyword density as clues, not ranking guarantees.
- Download the extension only from Mozilla Add-ons to avoid outdated or misleading third-party listings.
- Cross-check SERP overlay data with a dedicated SEO X-Ray tool or your own logs before making changes.
A quick competitive check that saved a rewrite
You are researching a keyword for a client's landing page. With SEOquake open in Firefox, you scan the top three results: one has a title tag of 58 characters, another uses the exact keyword in its H1, and the third has 12 internal links pointing to the page. You note that none of these metrics alone explain the ranking order, but together they suggest the page with the shortest title and fewest links still ranks first because of external authority. You decide to focus on backlinks instead of rewriting the title.
Three ways it goes wrong
- Outdated metrics Old tutorials mention PageRank, Alexa Rank, or MSN Index counts. These are no longer meaningful for modern SEO and can mislead your analysis.
- Third-party confusion App store pages outside Mozilla Add-ons may describe subscription fees or features that do not match the current free version. Always check the official listing.
- Over-reliance on quick checks Using this SEO extension for a fast SEO audit is fine, but ignoring deeper site crawl data, logs, or server-side issues leaves critical problems invisible.
Three things to check before acting
- Extension source Download only from Mozilla Add-ons to ensure you get the latest, accurate version without conflicting descriptions.
- Metric relevance Verify that the metric you are looking at (e.g., keyword density) is still used by search engines today. Some legacy features are obsolete.
- Browser compatibility SEOquake also works on Chrome and Opera, but behaviour may differ across browsers. Test on Firefox for consistency.
Common questions
Is SEOquake free for Firefox?
Yes, it is free on Mozilla Add-ons. Third-party listings may suggest otherwise, so rely on the official add-on page.
Can I use SEOquake for mobile SEO?
No, it is a desktop browser extension. For mobile SEO audits, use server-side tools or mobile-specific crawlers.
Does SEOquake still show PageRank?
No, PageRank was removed years ago. Any mention of it in tutorials or third-party pages is outdated.
