Link Prospecting: How to Find Quality Link Opportunities for Your Site

Link prospecting is the process of identifying websites and pages that are potential sources of inbound links. It is the stage of link building that most practitioners underinvest in — and the stage that most determines campaign quality. A well-qualified prospect list of 100 sites will produce better results than an unqualified list of 1,000.

This guide covers the prospecting methods that work for UK SMEs, the qualification criteria for evaluating prospects, and how to prioritise your outreach list for maximum SEO impact.

Prospecting Methods

There are five primary prospecting methods. Each produces a different type of prospect and is suited to different campaign types.

Competitor backlink analysis

Ahrefs / Semrush

Analyse the backlink profiles of your top-ranking competitors to find sites that have already linked to similar content. These are warm prospects — they have demonstrated willingness to link to content in your topic area. Filter for sites that link to multiple competitors but not to you (the 'link gap') — these are the highest-priority prospects.

Best for: Resource-based outreach, guest posting

Topical search prospecting

Google search operators

Use Google search operators to find sites that publish content in your topic area. Queries like 'intitle:SEO consultant London resources', 'inurl:blog/seo-london', or 'site:*.co.uk SEO consultant resources' surface sites that are topically relevant and may have resource pages or roundup articles that could include your content.

Best for: Resource page link building, roundup inclusion

Link intersection analysis

Ahrefs Link Intersect

Identify sites that link to two or more of your competitors but not to you. These sites have already demonstrated topical relevance and editorial willingness to link — they are the most efficient prospects because you know they link to similar content. The link gap is the most actionable output of competitor analysis.

Best for: All campaign types

Brand mention monitoring

Google Alerts / Ahrefs Alerts

Monitor for unlinked mentions of your brand, products, or key personnel. When someone mentions your business without linking to it, a simple outreach asking them to add a link converts at very high rates — they have already demonstrated awareness of and interest in your brand. This is the easiest link acquisition available.

Best for: Unlinked mention conversion

Industry publication research

Manual research

Identify the key publications, blogs, and resource sites in your industry. For a London SEO consultant, this includes UK SEO publications, business press, and industry-specific trade publications. These are the highest-authority prospects and require the most tailored outreach — but the links they produce carry the most weight.

Best for: Digital PR, expert commentary, guest posting

Qualification Criteria

Not every site you find through prospecting is worth pursuing. Qualification filters your raw prospect list down to the sites that are genuinely worth the outreach investment.

Topical relevance

The site covers topics related to your content. A link from a topically relevant site carries more weight than a link from a high-authority but irrelevant site.

Threshold: Direct or adjacent topic coverage

Domain Rating / Authority

The site has sufficient authority to pass meaningful link equity. For most UK SME sectors, DR 30+ is a reasonable minimum threshold.

Threshold: DR 30+ (Ahrefs) / DA 25+ (Moz)

Organic traffic

The site receives genuine organic traffic. A high DR site with zero organic traffic may have a manipulated link profile and is not worth pursuing.

Threshold: 500+ monthly organic visits minimum

Editorial standards

The site publishes original content and does not sell links indiscriminately. Sites with 'write for us' pages that accept any submission, or that clearly sell links, are not worth pursuing.

Threshold: Original content, no obvious link selling

Link opportunity

There is a plausible reason for the site to link to your content — a resource gap, a relevant article, or a news story you can contribute to.

Threshold: Clear, specific link opportunity identified

Contact availability

You can find a specific contact — a journalist, editor, or site owner — to pitch to. Generic contact forms have very low response rates.

Threshold: Named contact or direct email available

From Our Practice

The prospecting method that produces the most consistent results for London SMEs is competitor backlink analysis combined with link intersection analysis. Starting with sites that have already linked to your competitors eliminates the topical relevance question — you know they link to content in your space. The link gap (sites that link to competitors but not to you) is the most actionable output of this analysis.

The qualification step that most practitioners skip is organic traffic verification. A site can have a high domain rating from historical links while receiving zero current organic traffic — often a sign of a penalised or abandoned site. Links from these sites carry little value and can occasionally be harmful. Always verify organic traffic before adding a prospect to your outreach list.

Frequently Asked Questions

What is link prospecting in SEO?

Link prospecting is the process of identifying websites and pages that are potential sources of inbound links. It involves finding sites that are topically relevant, have sufficient authority, maintain editorial standards, and have a plausible reason to link to your content.

What makes a good link prospect?

Four characteristics: topical relevance, domain authority (DR 30+ typically), editorial standards (original content, no obvious link selling), and a clear link opportunity. Sites that fail on any of these criteria are generally not worth pursuing.

How many link prospects do I need?

For a typical campaign: 100–300 qualified prospects to produce 10–30 links. Conversion rates vary by campaign type — resource outreach 5–15%, digital PR 10–25%, expert commentary 15–30%. A well-qualified list of 100 outperforms an unqualified list of 500.
