Link Intersect: The Fastest Way to Find Link Prospects

5 August 2026 · 8 min read

Link intersect is the fastest way to find link prospects: it shows you the sites already linking to several of your competitors but not to you.Those sites have proven two things — they cover your topic and they give links — which makes them far warmer than any cold list of high-authority domains. Instead of guessing who might link to you, you start with sites that demonstrably link to people just like you. Here's how to run it and turn the output into links.

The short version

Enter two or three competitors; get the sites linking to them but not you, ranked by how many they already link to. Start at the top (most relevant, most link-happy), qualify each by authority, and pitch something worth linking to. It beats cold outreach because relevance and willingness are pre-proven.

1. Why the intersect beats a cold list

Most link prospecting starts from “who has high authority in my space” — and most of those sites never respond, because you have no relevance to them. Link intersect inverts it: a site linking to three of your competitors has already shown it writes about your topic and hands out links. The probability it links to you too is an order of magnitude higher. You're not asking a stranger; you're asking someone who already does this.

2. Run it in three steps

  1. Pick competitors. Choose two or three direct competitors — sites targeting the same audience, not just big names in the industry. Open link intersect and enter them alongside your domain.
  2. Read the ranked gap. The tool returns domains linking to your competitors but not you, ranked by how many of them each already links to. A site linking to all three is your hottest prospect. Seoluma also filters out platforms that link to everyone (blog hosts, social sites) so the list stays actionable.
  3. Qualify before you pitch. Run promising prospects through the authority checker. A relevant niche site at DR 35 is worth more than a generic directory at DR 3 — chase relevance and authority together.

3. Turn the list into links

A prospect list is not links — the pitch matters. The sites that already link to competitors usually do so because of something worth citing: a resource, a data point, a genuinely useful page. Give them the same reason. The strongest, most durable angle is original data or a genuinely useful tool that's better than what they currently link to. Reclaiming unlinked brand mentions and offering a clearly superior resource both convert well.

With Seoluma: the whole workflow is free — link intersect for the prospects, the authority checker to qualify them, and the backlink checker to confirm new links landed. See the wider link-building playbook for what the data says actually moves authority.

4. Why relevance ranking matters

Not every high-authority prospect is a good target. A DR 80 site that links to none of your competitors is a long shot; a DR 40 site linking to all three is a near-certainty. Sorting by proven relevance — competitor overlap — rather than raw authority is what makes link intersect efficient. It points your limited outreach time at the prospects most likely to say yes.

Frequently asked questions

What is link intersect?

Link intersect is a technique that finds the websites linking to several of your competitors but not to you. Those sites have already proven they link out in your niche, which makes them the warmest, most relevant link prospects — far better targets than cold outreach to random high-authority sites.

Why is link intersect better than other prospecting?

Because it filters for proven relevance and willingness. A site linking to three of your competitors clearly covers your topic and clearly gives links. Ranking prospects by how many competitors they already link to surfaces the highest-probability targets first, so your outreach time goes where it converts.

How many competitors should I enter?

Two or three direct competitors is the sweet spot. Requiring a prospect to link to at least two of them filters out sites that link to everyone (which won't be persuadable) and generic platforms, leaving genuinely relevant, reachable targets.

Is link intersect free in Seoluma?

Yes. Seoluma's link intersect is free with no signup, computed from an open index of 7.1 billion links. You enter your domain and your competitors and get the gap list ranked by relevance — the same job paid suites charge for.
