There are two kinds of link strategy: one based on "intuition" — where you think you should have links. And one based on data — where you've already seen it work for competitors. The second one wins every time.
Competitor backlink analysis isn't just another technique — it should be the first step in any SEO plan. Why search alone for what works when your competitors have already done the work?
Step 1: identify the real competitors
SEO competitors ≠ business competitors
The links that move your rankings come from sites that rank for your keywords — not from those you think compete with you commercially.
The common mistake: a car-rental site only looks at other car-rental sites. But on its SERPs, the top results aren't always business competitors — sometimes they're Booking.com, TripAdvisor, and travel blogs.
How to identify:
- Pick 5 keywords that are critical to your business.
- Search them on Google in incognito mode.
- Note the top 10 results for each keyword.
- Find the sites that repeat — those are your real SEO competitors.
Step 2: export the link profile
Ahrefs / Semrush — the basic export
Open one of the tools, enter the competitor's domain, and go to "Backlinks" or "Referring Domains". Export to CSV.
What to export:
- Referring domains (linking domains — not individual links).
- DR of each domain.
- Anchor text used.
- Target URL (which page the link points to).
- Link status (whether it's still live).
Do this for 3–5 competitors. You'll end up with 1,000–5,000 links in total.
Step 3: filter for replicable opportunities
Link Intersect — the gold of the analysis
Look for domains that link to 3+ competitors but not to you. These are the highest-probability opportunities.
Ahrefs has this in the "Link Intersect" tool. Semrush calls it "Backlink Gap." Both give you the same thing: domains that link to several of your competitors, but not to you.
The logic: if a domain links to 3 of your competitors, it's highly likely to link to you too. They've already shown they're open to linking to your niche.
Further filtering — which opportunities are most valuable?
| Attribute | Recommended threshold |
|---|---|
| Domain DR | 30+ |
| Organic traffic | 1,000+/month |
| Links to 3+ competitors | Yes |
| Link type | Content (not a directory) |
Step 4: sort by ease and value
Effort × Value Matrix
Different links require different effort and return different value. Place them in quadrants and start from the bottom-left.
Common categories, from easier to harder:
- Resource pages ("Best tools for X") — the easiest. Send a pitch — there's a good chance of being added.
- Broken links — you find a broken link on a site, propose your replacement. High success rate.
- Guest posts — requires writing but reasonable response rates.
- Mentions without a link — the site mentioned you without linking. Send a friendly pitch — most will add a link.
- Editorial / news — requires PR pitch or press relations. Hardest, but most rewarding.
Step 5: action — outreach or exchange
Personalized templates
Outreach success comes down to personalization. Never send a generic mass email.
A pitch structure that works:
- Subject line: specific to their page. Not "linkbuilding inquiry".
- Opening: a genuine compliment about something specific they did (not "I love your site").
- Opportunity: what you're proposing — a complementary link, supporting content, a guest post.
- Value: why this is good for their reader, not just for you.
- CTA: a specific question, not a general ask.
Alternative: exchange instead of outreach
If the link is on a blog / site with a private owner who's also building their SEO — propose an exchange. Response rates are 3–5× higher. The complete link-exchange guide explains how.
Outreach is a numbers game. If your response rate is 3% — you'll need 100 emails to get 3 links. Triangular exchange brings that up to 15–25%.
FAQ
How many competitors should you analyze?
3–5 is the optimal number. Fewer = thin data. More = noise. Start with three, then add 1–2 as needed.
Can you do this without Ahrefs / Semrush?
It's hard. There are free tools (Moz Link Explorer free tier, Ubersuggest) but the data is shallow. The investment in Ahrefs ($99/month for two weeks to a month) pays off for any serious project.
How long does it take to analyze 5 competitors?
The analysis itself: 2–3 days. The outreach growing out of it: 2–6 ongoing months. The impact on rankings: 4–8 months.
What if my competitors are buying all their links?
Then they're vulnerable too — identify the suspect sites (PBNs) and don't replicate them. Only replicate the organic links. In that case, systematic exchange creates a long-term advantage for you.
