What is a Backlink Checker?
A Backlink Checker is an SEO tool that shows you which other websites are linking to a particular domain. Backlinks are one of the most important ranking factors for Google – they act as votes of confidence. By analysing a domain's backlink profile, you can see how authoritative it is, identify toxic links, and find opportunities for your own link building. This free backlink checker uses the SEO Review Tools API to retrieve real backlink data, including the source URL, anchor text, domain authority (DA), and page authority (PA).
How to Check Backlinks for a Domain
- Enter the domain name you want to check (e.g., "nyxbo.com").
- Provide your API key from SEO Review Tools (or use the demo key for testing).
- Click "Check Backlinks" – the tool fetches the backlink profile from the API.
- Review the summary stats (total backlinks, referring domains) and the detailed table.
- Use the data to analyse your link profile or spy on competitors.
