Powered by live search data. ## How It Works 1 ### Enter a competitor Not your own site. You already know what links to you. 2 ### Ignore the total The list of sources is the part worth reading. 3 ### Mark the local ones Those are the ones you can plausibly approach. ## What a backlink actually is A link from another website to yours. Search engines read it as a signal that somebody thought you were worth pointing at, which is why a handful from real local organisations counts for more than a long list from directories nobody opens. ## Links against referring domains Links counts every individual link. Referring domains counts the separate websites they came from. The second number is the more honest one, because a hundred links from one site is a single relationship, not a hundred. ## Why volume is the wrong target Chasing a link count leads straight to the kind of links that do nothing. One link from a local organisation with a real audience is worth more than a thousand from a network built to sell links, and it is usually easier to get than people expect. ## Explore More Free Tools & Services [All Free SEO ToolsBrowse our full toolkit](/tools/)[Domain Authority CheckerCheck the authority score](/tools/domain-authority-checker/)[All Free ToolsDone-for-you rankings](/tools/)[Check My RankingSee how to grow your authority](/tools/google-rank-checker/) ## Frequently Asked Questions **Q: How many links do I need?** There is no number. A few genuine local links beat hundreds of directory entries, and the directory route creates work you have to undo later. **Q: Can I look at competitors?** Yes, and that is the main use. Their sources show you which local organisations link to businesses like yours. **Q: Should I buy links?** No. It risks a penalty and it addresses the wrong thing for local search, where profile quality and reviews carry more weight. **Q: What is a spam score?** An estimate of how manipulative a link profile looks. A high one on your own site is worth investigating before it becomes a problem. ## The finding is easy. The asking is the work. Seeing who links to a competitor takes a minute. Approaching them takes persistence, and that is the part most businesses never start.

The chamber of commerce, a supplier page, the club you sponsor, the local paper that covered something you did. Looking at a competitor's links is the fastest way to find yours, because most of those sources will link to any local business that asks. They are not competitive. They are simply unknown to you until you look. Volume is the wrong measure. A hundred links from directories nobody visits are worth less than one from a local organization with a real audience, and the second kind is usually easier to get than people expect. ## How to use it - Enter a competitor domain rather than your own. - Ignore the total. Read the list of sources. - Mark the local ones you could plausibly approach. - Ask. Most local link sources say yes to anybody who bothers. ## Why it matters Link building for a local business is mostly a research problem. The opportunities exist within a few miles and the obstacle is not knowing they exist. ## Questions people ask ### How many links do I need? No number. A few genuine local links beat hundreds of directory entries nobody reads. ### Should I buy links? No. It risks a penalty, and for local search it addresses the wrong thing entirely. ### What is the easiest local link? Organizations you already deal with. Suppliers, trade bodies, clubs you sponsor. They tend to say yes because you already have a relationship. ## Related tools - [Domain Authority Checker](/tools/domain-authority-checker/) - [Local Citation Checker](/tools/local-citation-checker/) - [Website Traffic Checker](/tools/website-traffic-checker/)
