SEO Book Rank Checker
Checks where a domain ranks in Google, Bing, or Yahoo for specific keywords using a Firefox extension that runs locally on your machine.
If you have ever treated a single rank check as a complete SEO verdict, you already know the number is not the whole story without location, device, and personalisation context.
Key points
- Install the extension in Firefox and restart the browser before it works.
- Enter one URL and multiple keywords at once for faster batch checks.
- Export results to CSV if you need to analyse rankings outside the tool.
- Treat each check as a snapshot, not a trend — it does not track changes over time.
- Compare positions with Google Search Console data to account for measurement differences.
The same keyword, three different scores
An SEO runs the SEO Book Rank Checker for the query 'organic dog food' on a client site. From a Firefox browser in London, the page ranks position 4 on Google UK. Switching the search engine version to Google US shows position 12. Adding a second keyword 'best grain-free dog food' returns position 7 on Bing but position 19 on Google. The tool reports all three positions correctly, but none reflect mobile rankings or personalised results for logged-in users. The SEO exports the CSV and notes the context alongside each number.
Three situations where this changes your decision
- Quick spot check You need to verify whether a new page ranks for its target query without waiting for a full tracking tool. This extension gives an instant answer.
- Competitor comparison Enter a competitor's URL alongside your own to see where each domain appears for the same keyword. Useful for gap analysis.
- International ranking test Switch the search engine version to a different country to see how your page performs in that market before investing in local SEO.
Three ways it goes wrong
- Ignoring personalisation The tool reports a raw SERP position, but logged-in users see personalised results. Your number may not match what most visitors see.
- Missing device context It checks desktop rankings by default. Mobile and tablet positions can differ significantly, especially for local queries.
- Overlooking SERP features A position 1 ranking may be pushed below a featured snippet or knowledge panel. The tool reports the organic slot, not the visible area.

Is the SEO Book Rank Checker free?
Yes, it is described as free and runs locally on your computer rather than as a hosted service.
