Link prospecting: how to find sites worth pitching
Link prospecting means building a list of sites that have a reason to link to you. Start with sites that already link to your competitors, add pages found with search operators, then remove anything that fails a quick quality check before you look for a contact.
In short
- The most reliable source of prospects is the list of sites that link to two or more competitors but not to you.
- Hunter's outreach guide, updated in April 2026, reports that about 1.3% of prospects turn into a link in standard cold outreach, so 10 links can need a list of several hundred qualified sites.
- BuzzStream's June 2026 study rated 96.2% of roughly 257,000 guest post sellers as low quality, which is why vetting belongs inside prospecting and not after it.
- Every prospect needs a recorded link reason, such as a broken link, a resource list or an unlinked mention, because the reason decides the pitch.
- Sort prospects into three tiers so that hand-written emails go to the sites that matter most.
You find sites that might link to you by starting from evidence that they link to pages like yours. The best list is the set of sites that already link to two or more of your competitors. After that come pages that exist to link out, pages that mention your topic or brand without a link, and writers who have covered similar stories.
Prospecting is not collecting as many domains as possible. A prospect is a site, a specific page, and a reason that page would link to you. If you cannot write the reason in one line, it is not a prospect yet.
Start with a link reason
The reason comes before the list, because it decides where you look and what you send. The usual reasons are a broken link you can replace, a resource list you belong on, a statistic you can supply, a mention of your brand with no link, a guest article, or a commercial partnership.
Each reason maps to a tactic with its own page on this site, such as broken link building or unlinked mentions. Pick one or two reasons per campaign. A list that mixes all of them produces a vague email.
Where prospects come from
| Source | What you get | Best for |
|---|---|---|
| Competitor referring domains and link intersect | Sites that link to several competitors but not you | Almost every campaign |
| Search operators | Resource pages, link lists, “recommended tools” pages | Resource and broken link pitches |
| Content search in an SEO tool | Articles that discuss your topic without citing you | Data citations, expert quotes |
| Brand monitoring | Pages that name you without linking | Reclaiming mentions |
| Journalists who covered similar stories | People, not sites | Digital PR |
| Podcast directories and association member lists | Hosts and organisations with a natural reason to list you | Interviews, memberships, partner links |
| Your own customers, suppliers and partners | Sites with an existing relationship | First links for a new site |
The first row deserves the most time. Link gap analysis explains how to run the comparison. A site that links to three competitors has shown it links to your kind of page, which is the strongest signal you can get before sending an email.
The last row is the one people skip. Partner and supplier links need no cold outreach at all, and the partner links page covers how to ask.
Search operators that still work
Operators find pages whose job is to link out. Combine your topic with patterns such as:
intitle:resourcesorinurl:links"useful links"or"recommended tools""write for us"or"guest post", with caution
The third group needs the caution. A public “write for us” page with a price list is one of the plainest signs of a site that sells links to anyone. BuzzStream’s June 2026 study of roughly 257,000 guest post sellers rated 96.2% as low quality and found that 39.6% had no organic traffic at all.
Scraping search results at volume has also become harder. One prospecting tool, Link Hunter, is reported to have shut down after Google removed the option to load 100 results per page. Expect to export smaller batches and lean more on backlink data.
Qualify before you look for a contact
Finding an email address costs time and credits, so remove weak sites first. A five-minute check, drawn from standard publisher vetting practice, is enough at this stage:
- Read three recent posts. Would anyone subscribe to this site?
- Check the organic traffic trend in an SEO tool. Reject sites with none, or with a collapse after a Google update.
- Look at what the site ranks for. A technology blog that ranks for casino and loan terms sells links.
- Open five random posts and count commercial outbound links with exact-match anchors.
- Check for a named author with a real profile.
These are working methods, not guarantees. The full scoring approach is in how to vet a publisher. Do not filter on an authority score alone: relevance was the primary factor for 58.6% of senior SEOs in uSERP’s September 2026 survey, and scores such as Domain Rating can be inflated.
Segment and tier the list
Record four things for every prospect: the page, the link reason, the type of person you will write to, and a tier.
- Tier A: the sites you most want. Each gets a hand-written email.
- Tier B: good sites. A template with one or two personal lines.
- Tier C: acceptable sites. A template with light edits.
Tiering protects your time. It also protects your sender reputation, because the sites most likely to complain about a lazy email are the ones you most want to keep.
How big the list needs to be
Work backwards from the number of links you want. Hunter’s outreach guide, updated in April 2026, reports that about 1.3% of prospects become a link in standard cold outreach. Reply rates set the ceiling: the Backlinko and Pitchbox study of 12 million emails in 2019 found 8.5%, and BuzzStream’s 2025 platform data across 51 million emails is reported at 3.59%.
On those figures, 10 links from cold outreach can need 700 or more qualified prospects. A strong link reason changes the sum. A broken link you have found on the page, or a mention that already exists, converts far better than a guest post pitch. That is why a short list with clear reasons beats a long scraped one.
Tools and what they cost
You need a backlink tool for competitor data and somewhere to keep the list. A spreadsheet works for the first campaign. Dedicated platforms add contact discovery and duplicate checks: in October 2026, BuzzStream listed its Starter plan at $49 a month and Pitchbox listed Pro at $210 a month billed annually. Our BuzzStream review and the outreach tools comparison set out what each plan includes.
Where to go next
Once the list is qualified and tiered, the next step is finding the right contact and verifying the address. For how prospecting fits with pitching, checks and tracking, see how a link building campaign runs. Terms such as referring domain and link intersect are defined in the glossary.
Common questions
What is link prospecting?
It is the research step of link building. You find sites and pages that could plausibly link to you, check that they are worth having, and record why each one might say yes.
How many prospects do I need for one link?
Hunter's outreach guide, updated in April 2026, reports a conversion of about 1.3% from prospect to link for standard cold outreach, which is roughly 75 prospects per link. Warm contacts and strong link reasons convert far better.
Which tools are used for link prospecting?
Backlink tools such as Ahrefs and Semrush for competitor links, search operators in Google for resource pages, and outreach platforms such as BuzzStream or Pitchbox to store and qualify the list.
What search operators find link prospects?
Common ones are intitle:resources, inurl:links, "useful links" and "recommended tools" combined with your topic. They surface pages that exist to link out.
Should I prospect by Domain Rating?
Use it as a filter, not a target. Relevance and real organic traffic tell you more than an authority score, which can be inflated.
