Link prospecting

Link prospecting is the research step of link building: finding the specific websites and pages that could plausibly link to you, then filtering them down to the ones worth contacting. It decides most of what outreach can achieve, because no message rescues a pitch to the wrong site.

Also called: backlink prospecting, link prospect research

A prospect is not a website; it is a page and a reason. "Sites in our niche" is a list. "This article cites a 2019 statistic that our new survey replaces" is a prospect. The more specific the reason, the more likely a person on the other end agrees that a link belongs there.

Prospecting usually takes more time than any other part of link building, and it is the part most often rushed. Teams that pull a few thousand domains from a database, filter them by an authority score and start sending are prospecting by metric instead of by fit - which is why their reply rates are low and their links come disproportionately from sites that sell them.

Link prospecting methods

Each method finds a different kind of reason to link, and most programs use several:

  • Competitor backlink gaps. Sites that link to two or three of your competitors but not to you already link to your subject. A backlink tool's link-intersect or backlink-gap report finds them.
  • Links to similar resources. If you have a guide, a tool or a study, find who links to the best existing ones on the same subject. Those pages are the natural audience for a better one.
  • Search operators. Queries such as intitle:resources plus your topic, or "write for us" plus your topic, surface resource pages and publications that accept contributors. Plain search is free and still one of the best prospecting tools there is.
  • Broken links. Dead pages that many sites still link to are prospects for a replacement pitch - if you have something that genuinely replaces them.
  • Unlinked mentions. Pages that already name your brand, product or research without linking to you. These are the warmest prospects there are.
  • Journalist requests. Source-request services such as HARO and Qwoted deliver prospects who have stated exactly what they need, with a deadline attached.
  • Real relationships. Partners, suppliers, associations and events you are genuinely involved with often have pages where a link to you is simply accurate.

How to qualify a link prospect

Qualifying is where most of the value is created. A short list of strong prospects beats a long list of weak ones on every number that matters, including the health of the mailbox you send from. Five questions do most of the work:

  • Is it relevant? Does the page cover your subject, and would its readers plausibly want your resource? This is the test that matters most.
  • Does it have a real audience? Does the site attract search traffic and readers of its own? Third-party traffic estimates are rough, but an impressive authority score with no visible audience is a warning sign.
  • Does it have editorial standards? Real authors, edited content, outbound links chosen with care. A site whose recent posts are a wall of unrelated guest articles with commercial anchors is selling links.
  • Does it link out at all? Some publications never link to outside resources, or nofollow everything. Better to know before you write.
  • Is there a person to reach? An editor, author or owner you can actually contact. A prospect with no reachable human is not a prospect yet.

Tools produce candidates, not prospects

Whichever tools you use, what comes out is a list of candidates. Turning a candidate into a prospect - deciding that this page, for this reason, should hear from you - is the judgement the whole program rests on, and it is the step that cannot be skipped by buying a bigger database.

Common mistakes

  • Filtering on authority alone. Domain Rating or Domain Authority thresholds select for sites that optimize their own score - a group that overlaps heavily with link sellers. Use the score to triage, then judge relevance.
  • Prospecting domains instead of pages. The pitch is about a specific page. A domain on a list tells you nothing about what to say.
  • Ignoring history. Pitching a site a colleague contacted last month, or one that already links to you, wastes the relationship.
  • Trusting "write for us" pages. Some belong to real publications; many more front link-selling operations. Read the site's recent posts before adding it.
  • Skipping the person. A list without named contacts produces generic emails to generic inboxes, which is how outreach gets ignored.

Common questions

How many link prospects do I need?

Fewer than most tools will hand you. A campaign is limited by how many well-matched pages exist for one resource, not by how many domains a database returns, and a short, highly relevant list consistently does better than a long, loose one. Size the list to the resource, then stop.

Can I do link prospecting without paid tools?

Yes. Search with operators, Google Alerts for brand mentions, Search Console's Links report for the links you already have, and free source-request emails such as HARO cover a great deal. Paid backlink indexes mainly add competitor link data and speed.

Related terms

Link building outreach

Link building outreach (often just "link outreach") is contacting the people who run other websites - editors, writers, site owners, journalists - to give them a genuine reason to link to your content. It is how most deliberately earned links begin, and it succeeds or fails on relevance rather than volume.

Domain Rating (DR) and Domain Authority (DA)

Domain Rating (DR) and Domain Authority (DA) are third-party scores that estimate the strength of a website's backlink profile on a 0–100 scale. DR is Ahrefs' metric and DA is Moz's; neither is a Google metric and neither is used by Google to rank anything.

Broken link building

Broken link building is finding links on other sites that point to pages which no longer exist, then suggesting your own working page as the replacement. The pitch works because you are reporting a real defect on someone's page, not asking a favor.

Unlinked mention

An unlinked mention is a place where a website names your brand, product, or research in its text without linking to you. Asking for the link to be added is one of the highest-conversion requests in link building, because the endorsement already exists.

Toxic backlink

A toxic backlink is a link from a site whose only apparent purpose is to manipulate search rankings - link farms, private blog networks, hacked pages, or directories with no editorial standard. The term is an SEO-industry label, not a Google classification.
