Link Prospecting: How to Build a List of Sites Worth Contacting
Link prospecting is the research step of link building: finding websites that could plausibly link to you, checking each one is worth a link, and recording why they would link and how to reach them. Outreach only works as well as the list behind it.
Link prospecting means finding and vetting websites that have a genuine reason to link to you, before any outreach email is written.
Sort prospects by the reason they would link (a listing, a relationship, a mention, a dead resource, a story) because each reason needs a different approach.
Your competitors' backlinks are the richest prospect source: a site linking to several of your rivals is part of your market.
Qualify every prospect on relevance, real traffic, a believable reason to link, a working route in and how carefully it links out; domain rating comes last.
A short, checked list of a few dozen prospects beats a scraped list of thousands that nobody can work through.
Most link building fails before the first email goes out.
The problem isn't the pitch. It's the list.
Link prospecting is the research step that decides who you contact, and a weak list makes good outreach look bad.
Below: the five prospect types, where to find them, how to qualify each one and what a usable list looks like.
What Is Link Prospecting?
Link prospecting is the process of finding websites that could plausibly link to yours, checking each is worth a link, and recording the reason they would link and how to reach them.
It sits between strategy and outreach.
Strategy decides what you're offering. Prospecting finds who would want it. Outreach makes the ask.
Here's a quick example:
A roofing firm wants more local links. Prospecting turns up a town business directory listing four of its rivals, a builders' merchant that features "recommended contractors", and a local news site that covered a storm-damage story last winter.
Three prospects. Three different reasons to link. Three different approaches.
What Link Prospecting Is NOT
It isn't exporting a list of high-authority domains in your niche.
It isn't buying a "guaranteed placements" spreadsheet.
And it isn't outreach. If you're writing emails before you know why each site would link, you've skipped prospecting.
Why Does Link Prospecting Matter?
Prospecting matters because the quality of your list caps the results of everything after it.
Here's why I spend more time on the list than on the emails.
Relevance Beats Volume
A link from a site your buyers read does two jobs. It can send visitors, and it tells search engines where you belong.
A link from a random high-authority site does neither well.
Bad Prospects Burn Time and Reputation
Every email to someone with no reason to link is wasted effort.
Send enough of them and your domain starts looking like a spammer's to inbox filters.
Some Prospects Are Risks, Not Opportunities
Google's spam policies list "low-quality directory or bookmark site links" and excessive link exchanges as examples of link spam.
Good prospecting filters those out before anyone is tempted.
The Five Types of Link Prospect
I sort every prospect by the reason it would link.
That reason decides the approach, so it's the most useful column in the sheet.
Prospect type
Why they'd link
How you get the link
Directories and listings
They exist to list businesses like yours
Sign up, sometimes pay
Relationships
You already work together
Ask: suppliers, partners, associations, clients
Existing mentions
They already name you
Ask them to add the link
Dead or weak resources
Their page links to something broken or outdated
Offer a genuine replacement
Editorial
You have a story, data or expertise
Pitch: expert comment, data, guest articles
Directories and Listings
These are the easiest wins, because no persuasion is needed.
Resource pages and guides in your niche that link to pages which no longer exist.
These only work if you have a true replacement. Broken link building covers the method.
Editorial
Publications, trade titles, podcasts and blogs your buyers read.
These need something worth covering: data, a strong opinion or a real story. That's digital PR territory.
Where Do You Find Link Prospects?
The best prospect sources are your competitors' backlinks, targeted Google searches and your own business relationships.
Here's how I use each.
Your Competitors' Backlinks
Start here.
Export the referring domains of the five to ten businesses that outrank you, merge them, and count how many competitors each domain links to.
A site linking to one rival might be a coincidence.
A site linking to most of them is part of your market, and you should probably be there too.
This is also how you find "best X in [town]" listicles that feature your competitors and not you. My guide to competitor backlink analysis goes deeper on reading those profiles.
Targeted Google Searches
Search operators find prospects no backlink tool will show you, especially for small towns and niche trades.
A few patterns I use:
[your trade] [town] directory for local listing sites
[your trade] intitle:resources for resource pages
[your town] "local businesses" for community and council pages
[your trade] association "find a member" for trade bodies
"[competitor name]" -site:competitor.com for pages mentioning rivals
Keyword tools hold very little data for a trade plus a small town. Searching Google directly fills that gap.
Your Own Relationships
Open your accounts system and your supplier list.
Every organisation you pay, get paid by or belong to is a potential prospect. These convert at a far higher rate than cold prospects in my experience, because the person already knows who you are.
How Do You Qualify a Link Prospect?
You qualify a prospect by checking five things: relevance, real traffic, a believable reason to link, a working route in and how it links out. Authority scores come last.
Here's the checklist I run on every row:
Check
Pass
Fail
Relevance
Covers your topic, trade or area
Unrelated niche, or covers everything
Real traffic
Has organic visitors and ranks for real searches
No traffic, or traffic only from spammy terms
Reason to link
You can say in one sentence why they'd link
"They have high authority" is the only reason
Route in
A sign-up form, named editor or contact
No contact details, or only a "write for us, fees apply" page
Link practice
Links out with care, to sources readers would want
Pages stuffed with unrelated outbound links
The traffic check removes dead directories and abandoned blogs fast.
The link practice check catches sites selling links. If every article links to a casino, a CBD shop and a payday lender, move on.
Domain rating measures how strong a site's own backlink profile is. It says nothing about whether your buyers read it.
Sort by authority and the top of your list fills with big general sites. Sort by competitor overlap or relevance and the sites that matter to your market rise instead.
Paid Placements
If a prospect asks for payment, that's advertising.
A good prospect list is one someone else could pick up and work through without asking you a single question.
These are the columns I use:
Domain and exact page where your link would sit
Prospect type (listing, relationship, mention, resource, editorial)
Reason to link, in one sentence
Competitors linked, a count, where relevant
Traffic note, enough to prove it's alive
Route, the sign-up URL, contact name or form
Cost, free or paid, with the price if published
Status (not started, contacted, live, declined)
Keep it short.
Thirty checked prospects with a reason on every row will produce more links than three thousand scraped domains.
Tip: sort the finished list by effort. Listings and relationships first, because they're quick. Editorial last, because it needs an asset and a pitch.
Prospecting Mistakes I See Most
Sorting by authority. Pushes your market's real sites down the list.
Skipping the traffic check. Fills the list with dead directories.
Prospecting with nothing to offer. Resource and editorial prospects need a page worth linking to.
One template for every type. A directory needs a sign-up, a supplier needs a friendly ask.
Never rechecking. Competitors keep earning links. Rerun the competitor step every few months.
Build Your First Prospect List This Week
Start with the quickest source: export the referring domains of your top five competitors and count the overlap.
Then add your own relationships and a handful of Google searches for your trade and town. Qualify every row against the five checks, and you'll have a list worth working before you write a single email.
The directory and listing layer is the part I've automated. My link prospecting automation pulls competitors from real search results, collects and filters their referring domains, finds each sign-up route and labels it free or paid, then I check every row by hand.
What is the difference between link prospecting and link building?+–
Link prospecting is the research stage: finding and vetting sites that might link to you. Link building is the whole process, which also includes creating something worth linking to, outreach, follow-up and tracking. Prospecting decides who you contact. Get it wrong and even a well-written outreach email goes to people with no reason to reply.
How many link prospects do I need?+–
Fewer than most people think. In my experience, a checked list of a few dozen prospects is often enough for a quarter of work for a small or local business. Volume matters less than fit. A list where every row has a clear reason to link will out-perform a list of thousands scraped from a tool and sorted by authority score.
What tools do I need for link prospecting?+–
A backlink tool that exports competitors' referring domains, Google search for operator queries, and a spreadsheet. Ahrefs, Semrush and Moz are common examples of backlink tools. A free option is to start from your own relationships and Google searches only, which works for local businesses but misses much of what competitors have.
Should I prospect for guest post opportunities?+–
Only on publications your buyers actually read, where you have real expertise to share. Google's spam policies list advertorials that include links passing ranking credit as link spam, and keyword-stuffed guest posts placed purely for links sit close to that line. Prospect for publications, not for link slots.
Can link prospecting be automated?+–
Parts of it can. Pulling competitors' referring domains, counting overlap, filtering out sites with no traffic and classifying which sites accept listings are all repeatable. Judging whether a site is a genuine fit, and what to say to the person who runs it, still needs a human. I automate the first part and check every result by hand.
