Build a backlink profile Google actually trusts

A backlinks checker shows you every external link pointing to a website — referring domain, exact URL, anchor text used, follow vs nofollow, and the authority of the linking page. It's the foundation of any link building strategy.

For your own site, it surfaces lost links you didn't know about, toxic links you should disavow, and patterns in what's working. For competitors, it's a complete playbook of who links to them and why.

Most paid tools charge $99-$499/month for backlink data. Our free checker covers the same data sources and serves the same use case — just without the dashboard fluff.

A backlink audit identifies links that are actively hurting your site — spammy directories, link farms, PBN footprints, irrelevant foreign-language sites, hacked sites linking to you, and negative SEO attacks.

Google's algorithms generally ignore obvious junk links, but at scale they can still drag rankings down or trigger manual penalties. If you've ever bought links, used a "link package," had a fired SEO agency, or noticed sudden ranking drops, you need an audit.

The tool scores every backlink for toxicity (0-100) based on dozens of signals: domain age, IP neighborhood, outbound link patterns, content quality, anchor text manipulation, and historical penalty patterns. Anything scoring 60+ gets flagged for disavow.

Backlink gap analysis finds websites that link to your competitors but not to you. Every one of those domains is a proven, in-niche link target — they've already shown they're willing to link to sites like yours.

This is dramatically more effective than cold link prospecting. Instead of guessing which sites might link to you, you have a list of sites that demonstrably link to your direct competitors. The pitch is simpler, the response rate is higher, and the links you get are topically relevant (which is what actually moves rankings now).

For most sites, backlink gap turns up 100-1000 link opportunities. Sort by domain authority, filter out spam, and you usually have 20-50 high-quality targets to work through.

Referring domains count the unique websites linking to you — not total links. This is the metric Google actually pays attention to. 100 links from one site = 1 referring domain. 1 link each from 100 different sites = 100 referring domains. The second case is vastly more valuable.

A healthy referring domain profile grows steadily, includes a mix of authority levels (you want some big-name links and some smaller-site links — all big-name looks unnatural), comes from topically relevant sites, and uses diverse anchor text.

This tool lets you check your own profile and any competitor's. The fastest way to improve link building: see which referring domains your top competitors have that you don't, and figure out how to earn the same links.

A link building tool finds high-quality, relevant link prospects, helps you reach out professionally, and tracks every link you earn. It turns link building from a vague aspiration into a measurable process.

The tool surfaces prospects from multiple sources: sites linking to competitors, sites covering your topic, resource pages in your niche, broken links you can replace, unlinked brand mentions, and journalist requests on your topic. Each prospect comes with contact info, domain authority, and a relevance score.

You then run outreach from inside the tool — pre-built email templates, personalization variables, follow-up sequences, and reply tracking. Links earned automatically get tracked and verified.
