Competitor Backlink Gap Analysis — Finding and Closing Link Deficits

Competitor Backlink Gap Analysis

A backlink gap analysis compares the client's link profile to 3-5 competitors to identify sites that link to competitors but not to the client. These existing linking sites are the highest-priority link acquisition targets because they have already demonstrated willingness to link to similar content.

Why Start With Competitors

Cold outreach to unknown sites has a 1-5% conversion rate. Outreach to sites that already link to competitors in the same niche has a 10-20% conversion rate — the site is already a proven linker in the category.

Tools Required

• Ahrefs — most comprehensive backlink data, Link Intersect feature
• Majestic — alternative, strong for UK and international sites
• SEMrush — Backlink Gap tool built in
• DataForSEO — API-accessible, best for automation at scale

Step 1 — Identify 3-5 Competitors

Select competitors who:

• Rank on page 1 for your primary target keywords
• Are in the same geographic area (for local SEO)
• Have comparable or slightly higher DR than the client
• Are not using exclusively black-hat tactics (inflated link counts with no real traffic)

Step 2 — Run the Link Intersect

In Ahrefs:

1. Go to Link Intersect (under Competitive Analysis)
2. Enter client domain in "But doesn't link to" field
3. Enter 3-5 competitor domains in the "Links to" fields
4. Export results

This generates a list of domains that link to at least one competitor but do not link to the client.

Step 3 — Prioritize Targets

Score each gap site on:

| Criteria | Weight | |---|---| | Number of competitors linked to (more = higher priority) | 40% | | Domain Rating (DR 30+ preferred) | 25% | | Topical relevance to client niche | 20% | | Traffic (non-zero Ahrefs estimated traffic) | 15% |

Filter out:

• Sites with DR under 15 (too weak to matter)
• Sites with zero estimated traffic (likely link farms)
• Sites in completely unrelated niches
• Sites that are themselves clients of a competitor agency (conflict)

Step 4 — Identify the Link Context

For each priority gap site, determine HOW they link to the competitor:

• Resource/links page? — pitch a similar resource
• Guest post? — pitch a guest post on the same site
• Editorial mention? — pitch a story angle or HARO-style expert quote
• Directory listing? — submit the client for the same directory
• Scholarship page? — create a scholarship page and apply

Matching the link context to the outreach angle is the highest-leverage tactic for closing the gap.

Step 5 — Outreach

Template (for resource page links):

Subject: Resource suggestion for [page title]

Hi [Name],

I was reviewing your [page title] resources and noticed you link to [competitor]. I wanted to suggest [client] as an additional resource — they [specific differentiator compared to competitor].

Here's the URL: [client URL]

Let me know if it's a fit.

[Name]

Key: Never frame this as "my competitor is there, add me too." Frame it as an additional resource that benefits their readers.

Reporting Gap Analysis Progress

Track monthly:

• Total gap sites identified
• Outreach sent
• Links acquired from gap sites
• Remaining gap vs competitors (DR of links the client still lacks)

The goal is not to match every competitor link — it is to close the specific gap that is suppressing rankings for the target keywords.
