Terms of Service

Last updated: 12 June 2026

Plain-English summary. These Terms are the agreement between you and RankNibbler when you use our website, tools, account or API. They tell you what you can and can't do, make clear that our data and reports are provided "as is" without guarantees, limit what we're liable for, and explain how the agreement can end. Nothing here is legal advice; if anything is unclear, contact us before relying on it.

Please read these Terms of Service ("Terms") carefully. They form a legally binding agreement between you ("you", "your", "Customer") and RankNibbler ("RankNibbler", "we", "us", "our") and govern your access to and use of our website, free tools, user accounts, site scans, dashboards, the API and any related services (together, the "Services"). By accessing or using the Services, creating an account, or clicking to accept these Terms, you agree to be bound by them. If you do not agree, do not use the Services.

If you use the Services on behalf of a company or other organisation, you confirm that you have authority to bind that organisation to these Terms, and "you" refers to that organisation.

1. The Services

RankNibbler provides on-page SEO analysis, website crawling and site audits, rank and visibility tracking, competitor and keyword research, backlink and reputation insights, uptime and cookie scanning, dashboards, reports and a developer API, at www.ranknibbler.com and related subdomains. We are based in the United Kingdom and serve users worldwide.

Some features are free and available without an account; others require a RankNibbler account or a paid plan. We may add, change, or remove features at any time (see section 13). These Terms apply to all of the Services, whether free or paid.

2. Eligibility and your account

• You must be at least 16 years old (or the age of digital consent in your country) and able to form a binding contract to use the Services.
• You are responsible for the accuracy of the information you provide and for keeping your account details up to date.
• You are responsible for safeguarding your password, API keys and any credentials, and for all activity that occurs under your account. Tell us promptly via our contact form if you suspect any unauthorised use.
• An account belongs to the organisation or individual that created it. You may invite team members to a workspace; you remain responsible for their use of the Services and for their compliance with these Terms.
• You may not share, sell, sub-licence, rent or transfer your account or access to the Services to anyone else, except to your own authorised users within your workspace.

3. Free tools, free accounts and fair use

We offer free tools and a free account tier so you can get value from RankNibbler at no cost. Free access is provided on a fair-use basis and may be subject to limits — for example, on the number of scans, projects, tracked keywords, API calls, lookups or reports per day, per account or per organisation. We may set, change or enforce these limits to keep the Services available and affordable for everyone.

We may rate-limit, throttle, temporarily restrict, or decline requests that we reasonably believe are excessive, automated beyond permitted use, abusive, or designed to circumvent our limits (for example creating multiple accounts to exceed a free quota). Free features are provided "as is" and we may modify or discontinue them at any time.

4. Plans, fees, billing and renewals

Some features require a paid plan. Where you purchase a paid plan, the following applies:

• Fees. You agree to pay the fees for the plan you select, at the prices shown at the time of purchase. Unless stated otherwise, fees are exclusive of VAT and other applicable taxes, which you are responsible for paying.
• Billing cycle and renewal. Subscriptions are billed in advance for the chosen period (e.g. monthly or annually) and, unless stated otherwise, renew automatically for successive periods until cancelled. By subscribing you authorise us (and our payment processor) to charge your payment method for each renewal at the then-current price.
• Price changes. We may change plan prices. For a price change affecting a renewal, we will give you reasonable prior notice, and the new price applies from your next renewal. Continued use after the change takes effect constitutes acceptance.
• Cancellation. You can cancel renewal at any time before the next billing date; cancellation takes effect at the end of the current paid period and you retain access until then.
• Refunds. Except where required by law (including certain consumer rights in the UK/EU), fees are non-refundable and we do not provide refunds or credits for partial periods, downgrades, or unused features. Where a statutory right to cancel or to a refund applies to you as a consumer, nothing in these Terms removes that right.
• Overdue or failed payments. If a payment fails or is overdue, we may suspend or downgrade your access until it is resolved.
• Upgrades. Some upgrades are currently arranged manually — you can ask to upgrade via our contact form and the terms of your plan will be confirmed to you before any charge.

5. Acceptable use

You agree to use the Services only for lawful purposes and in accordance with these Terms. You must not, and must not permit anyone else to:

• Use the Services to break the law, infringe anyone's rights, or analyse, attack or probe websites or systems you do not own or are not authorised to assess (see section 7);
• Resell, redistribute, sub-licence, or make the Services or the data/reports they produce available to third parties as a standalone product, or use them to build or operate a competing or substantially similar service;
• Use the Services, their output, or any data obtained through them to train, fine-tune or develop any machine-learning or AI model, or to create a dataset for that purpose;
• Scrape, crawl, harvest, or systematically extract the Services or our website by automated means except through the API in accordance with section 8 and your plan limits;
• Copy, frame, mirror, decompile, reverse-engineer, or attempt to derive the source code of any part of the Services, except to the extent this restriction is prohibited by law;
• Circumvent, disable or interfere with usage limits, rate limits, security, authentication, or access controls, or probe or test the vulnerability of the Services without our prior written consent;
• Introduce malware, conduct a denial-of-service attack, send spam, or otherwise interfere with or place an unreasonable load on the Services or our providers;
• Misrepresent your identity, impersonate others, or use the Services to generate, distribute or facilitate unlawful, deceptive, harmful, hateful, harassing or infringing content;
• Remove, obscure or alter any proprietary notices, or use our name, logo or brand without permission except as allowed by these Terms.

We may investigate suspected breaches and may suspend or terminate access in line with section 14. We may also rate-limit, block or revoke API keys that breach these rules.

6. The data, scores and reports we provide

Important. RankNibbler is an informational tool. Our metrics, scores, estimates, rankings, recommendations and AI-generated content are provided for general guidance only and may be incomplete, out of date, or inaccurate. They are not professional, legal, financial or business advice, and you should not treat them as guarantees of any outcome (such as search rankings, traffic, or revenue). You are solely responsible for any decision you make based on the Services.

Much of the data we surface — including search-engine results, volumes, rankings, traffic estimates, backlink data, AI-visibility signals, reputation and review data, and similar metrics — is derived from third-party data sources, public web pages, and estimation models. This data is provided to us "as is", may change without notice, and is not warranted by us for accuracy, completeness, timeliness or fitness for any purpose. Estimates are modelled approximations, not measured facts.

Where the Services display data attributed to a named platform or website (for example a search engine or a review platform), that attribution identifies the underlying subject of the data, not an endorsement by, or affiliation with, that platform. We are not affiliated with, endorsed by, or sponsored by any third-party platform whose public data may be referenced.

Operational and monitoring features — such as uptime monitoring and alerts — are provided on the same "as is" basis and may produce false positives or false negatives; they are not a guaranteed alerting or availability service, so you should not rely on them as your sole monitor.

7. Sites and URLs you analyse — your authorisation

When you submit a URL, run a scan, or configure monitoring, you instruct us to fetch and analyse the target page(s). You confirm that, for every site, URL or property you analyse, monitor or connect to RankNibbler, you either own it or are otherwise authorised to have it analysed, and that doing so does not breach any law, contract, robots directive that you are bound to respect, or third-party right.

This applies not only to sites you own, but also to any third-party profiles, listings or surfaces you choose to monitor or track through the Services — for example your reviews listings, social profiles, and the AI and search surfaces tracked by AI Visibility. You are responsible for ensuring that monitoring or tracking such third-party profiles, listings and surfaces complies with the relevant platform's own terms.

You are responsible for your use of the crawling, scanning and monitoring features, including the load they place on the sites you target and your compliance with those sites' terms. You will indemnify us for claims arising from your analysis of sites you were not authorised to assess (see section 17). We may decline, limit, or stop any scan at our discretion.

Some scanning features let you choose how our crawler treats a site's robots rules, including an option to proceed without applying them. If you use such an option, you confirm you are authorised to access the target site on that basis, and you are responsible for ensuring that doing so complies with the site's terms, any applicable robots or access directives, and the law. You are likewise responsible for the request rate and load your scans place on a target site.

8. API

If we make an API available to you, you may use it solely to integrate the Services into your own applications, in accordance with these Terms, any API documentation, and your plan's limits. In particular:

• API keys are confidential; you are responsible for all calls made with your keys and must keep them secure;
• We apply rate limits and quotas, and log API requests to operate, secure, meter and bill the Services;
• We may change, deprecate, version, throttle or discontinue API endpoints; we will use reasonable efforts to give notice of material breaking changes;
• You must not use the API to circumvent product limits, to bulk-export data for resale or model-training, or in any way prohibited by section 5;
• We may suspend or revoke API keys that breach these Terms or that we reasonably believe are compromised or abusive;
• The API is provided without any uptime or service-level guarantee unless separately agreed with you in writing, and its availability, endpoints and limits may change.

9. Intellectual property and licence

The Services, our website, software, design, text, graphics, logos, and the compilation and presentation of data and reports, and all related intellectual property rights, are owned by RankNibbler or our licensors and are protected by law. Except for the rights expressly granted to you in these Terms, we reserve all rights.

Subject to your compliance with these Terms (and payment of any applicable fees), we grant you a limited, non-exclusive, non-transferable, non-sub-licensable, revocable licence to access and use the Services, and to use the reports and outputs we generate for you, for your own internal business or personal purposes. You may share reports we generate with your own clients or colleagues for that purpose, but you may not strip our attribution where shown, present the Services as your own product, or otherwise breach section 5.

Your content. You retain ownership of the content you submit to the Services — for example your projects, backlink Remove, Disavow and Keep classifications, team-member records, support messages and monitor configurations. You warrant that you have the rights to submit that content, and you grant us a limited, worldwide, royalty-free licence to host, store, process and display it solely to provide the Services to you. We may remove content that breaches section 5.

Feedback. If you send us feedback or suggestions, you grant us a perpetual, irrevocable, royalty-free licence to use them without restriction, obligation or attribution.

10. AI-generated features

Some features use artificial intelligence to generate summaries, rewrites, suggestions and reports. AI output can be inaccurate, incomplete or unsuitable, may not be unique to you, and should be reviewed by a human before you rely on or publish it. You are responsible for checking AI output for accuracy and for ensuring your use of it complies with applicable law and any third-party rights. As between you and us, and to the extent permitted by law, you may use the AI output we generate for you as part of the reports licensed under section 9; we make no warranty that such output is original or non-infringing.

11. Privacy and data protection

Our handling of personal data is described in our Privacy Policy, our Cookie Policy, and — where we process personal data on your behalf — our Data Processing Agreement, each of which is incorporated into these Terms by reference. By using the Services you acknowledge those documents. Where you provide us with, or instruct us to process, personal data of third parties — for example through the sites you analyse, the contact details you add for outreach, or the third-party listings, reviews and profiles you choose to monitor — you confirm you have a lawful basis to do so.

12. Third-party services and links

The Services may rely on, link to, or interoperate with third-party services, data sources and websites that we do not control. We are not responsible for the availability, accuracy, content, or practices of those third parties, and your use of them may be subject to their own terms. Reference to a third party is not an endorsement.

Reporting infringing or unlawful content. If you believe that content made available through the Services infringes your rights or is otherwise unlawful, you can report it via our contact form, giving us enough detail to identify the content and the reason for your concern. We will review valid reports and may remove the content or suspend the account responsible.

13. Availability, changes and beta features

We work to keep the Services available but do not guarantee uninterrupted or error-free operation. The Services may be unavailable from time to time for maintenance, updates, or reasons beyond our control, and we may modify, suspend, or discontinue any part of the Services (including free features) at any time. Features labelled "beta", "preview", "experimental" or similar are provided for evaluation, may be changed or withdrawn, and are excluded from any service expectations to the fullest extent permitted by law.

14. Suspension and termination

• By you. You may stop using the Services at any time and close your account via the app or by contacting us. For paid plans, see the cancellation terms in section 4.
• By us. We may suspend or terminate your access — in whole or in part, with or without notice — if you breach these Terms, if your use poses a security, legal or operational risk, if required by law, or if we discontinue the Services. Where reasonable and the breach is curable, we will aim to give you notice and an opportunity to fix it before terminating for cause.
• Effect. On termination, your licence to use the Services ends and you must stop using them. We may delete or anonymise your data in line with our Privacy Policy and our retention practices; please export anything you need beforehand. Sections that by their nature should survive termination — including sections 5, 6, 9, 10, 15, 16, 17, 18, 19, 21 and 22 — survive.
• Data export. While your account is active, you can use the available export tools (such as CSV and PDF exports) to retrieve your data, and you may also make a data-portability request via our contact form as described in the Privacy Policy. After termination and a reasonable wind-down period, your data may be deleted or anonymised.
• Dormant accounts. We may close or delete free accounts that have been inactive for an extended period (for example 12 months), after reasonable notice to the account email.

15. Disclaimer of warranties

To the fullest extent permitted by law, the Services and all data, metrics, scores, estimates, recommendations, reports and AI output are provided "as is" and "as available", without warranties of any kind, whether express, implied or statutory, including any implied warranties or conditions of merchantability, satisfactory quality, fitness for a particular purpose, accuracy, title and non-infringement. We do not warrant that the Services will be uninterrupted, secure, or error-free, that defects will be corrected, or that any data, estimate, score or recommendation is accurate, complete, current, or will produce any particular result (such as improved rankings, traffic or revenue). Any reliance you place on the Services is at your own risk.

Nothing in these Terms excludes or limits any warranty or right that cannot be excluded or limited under the law that applies to you — including, for consumers, your statutory rights.

16. Limitation of liability

Nothing in these Terms limits or excludes either party's liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be limited or excluded.

Subject to that, and to the fullest extent permitted by law:

• We will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, business, goodwill, anticipated savings, data, or for any loss arising from your reliance on the Services' data, scores, estimates or recommendations, even if advised of the possibility;
• Our total aggregate liability arising out of or relating to the Services and these Terms, in contract, tort (including negligence) or otherwise, is limited to the greater of (a) the total fees you actually paid us for the Services in the three (3) months immediately before the event giving rise to the claim, or (b) fifty pounds sterling (GBP £50).

Because much of the Services is offered free of charge, you acknowledge that these limitations are a reasonable allocation of risk and are reflected in the price (including a price of zero for free features). Multiple claims do not enlarge this cap.

17. Indemnification

To the extent permitted by law, you agree to defend, indemnify and hold harmless RankNibbler and its officers, employees and agents from and against any claims, liabilities, damages, losses and reasonable costs (including legal fees) arising out of or related to: (a) your use of the Services; (b) your breach of these Terms or any law; (c) your analysis, scanning or monitoring of any site, URL or property you were not authorised to assess; (d) content or data you submit, generate or share; or (e) your infringement of any third-party right.

18. Confidentiality

In the course of using the Services you may come across information about RankNibbler that is not publicly available — for example beta or preview features, non-public pricing, how the API behaves, and details about how the Services are built or secured. You agree to keep any such non-public information confidential, to use it only to use the Services as permitted by these Terms, and not to disclose it to others, except where it has become public through no fault of yours or where the law requires you to disclose it.

For our part, we keep your account information confidential and handle your personal data in line with our Privacy Policy and, where it applies, our Data Processing Agreement.

19. Export controls and sanctions

You must comply with all applicable export, re-export, and economic-sanctions laws. You confirm that you are not located in, and will not use the Services in or for the benefit of, any country or party subject to applicable sanctions, and that you are not on any restricted-party list.

20. Changes to these Terms

We may update these Terms from time to time. The "Last updated" date above reflects the latest version. For material changes, we will take reasonable steps to notify you (for example by email or in-app notice). Changes take effect when posted, or on the date stated in the notice. Your continued use of the Services after the changes take effect constitutes acceptance. If you do not agree to the updated Terms, you must stop using the Services.

21. Governing law and jurisdiction

These Terms and any dispute or claim arising out of or in connection with them or their subject matter (including non-contractual disputes) are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction, except that if you are a consumer resident elsewhere, you may also benefit from any mandatory protections and the courts of your country of residence where the law so requires.

22. General

• Entire agreement. These Terms, together with the Privacy Policy, Cookie Policy and DPA and any plan-specific terms, are the entire agreement between you and us about the Services and supersede prior discussions.
• Assignment. You may not assign or transfer these Terms without our consent. We may assign them to an affiliate or in connection with a merger, acquisition or sale of assets.
• Severability. If any provision is held unenforceable, the rest remains in effect and the provision will be modified to the minimum extent needed to make it enforceable.
• Waiver. Our failure to enforce any provision is not a waiver of our right to do so later.
• Force majeure. Neither party is liable for failure or delay caused by events beyond its reasonable control.
• No partnership. Nothing here creates a partnership, agency or employment relationship between us.
• Notices. We may give notices via the Services, by email, or by posting on our website. You may contact us as set out below.
• Third parties. A person who is not a party to these Terms has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any of its terms.
