Link Building

Links remain one of Google's top three ranking signals. Link building is the practice of earning backlinks from other websites to increase domain authority and page-level ranking power. The goal is not simply to accumulate links - it is to earn citations from authoritative, topically relevant sources that signal trust to search engines. This skill covers ethical white-hat tactics for acquiring links, managing outreach campaigns, and maintaining a clean link profile free of toxic signals.

When to use this skill

Trigger this skill when the user:

• Wants to grow organic search rankings through off-page SEO
• Needs to run a digital PR campaign to earn editorial backlinks
• Is pitching journalists via HARO, Connectively, or similar services
• Wants to find and outreach for broken link building opportunities
• Is planning a guest posting strategy for a domain or niche
• Needs to audit a backlink profile for toxic or spammy links
• Wants to create a Google disavow file
• Is analyzing competitor backlink profiles to find link opportunities

Do NOT trigger this skill for:

• Internal linking strategy - use the content-seo skill instead
• Schema markup or structured data - use the schema-markup skill instead

Key principles

1. Quality over quantity - One editorial link from a domain with genuine authority beats 100 low-quality directory submissions. Google's algorithms have become highly effective at ignoring link spam, and low-quality links carry little to no value.

2. Relevance matters more than raw domain authority - A link from a niche blog with a Domain Rating (DR) of 30 that is closely topically related to your content is often more valuable than a DR 70 link from an unrelated general site.

3. Anchor text diversity looks natural - over-optimization gets penalized - A healthy link profile contains mostly branded anchors, naked URLs, and generic text. Heavy exact-match anchor usage is a reliable Penguin penalty trigger.

4. Link building is relationship building - Sustainable link acquisition comes from genuine relationships with journalists, editors, and content creators. Spray- and-pray mass outreach produces poor response rates and burns bridges.

5. Audit and disavow proactively - Negative SEO attacks and legacy spammy links can drag rankings down. Regular audits catch toxic links before they cause harm. Waiting until traffic drops is too late.

Core concepts

Link equity and PageRank flow - Each page has a certain amount of ranking power (historically called PageRank). Links from that page pass a portion of that equity to the destination. Pages with many strong inbound links pass more equity. Internal links also distribute equity within a site - editorial structure matters.

Dofollow vs. nofollow vs. sponsored vs. UGC - A rel="dofollow" (or absent rel) link passes full equity. rel="nofollow" is a hint to crawlers not to pass PageRank; Google treats it as a hint, not a directive. rel="sponsored" marks paid placements. rel="ugc" marks user-generated content. Nofollow links still drive referral traffic and brand awareness even without direct equity transfer.

Domain Authority vs. Page Authority - Domain Authority (Moz) and Domain Rating (Ahrefs) are third-party metrics that estimate a domain's overall link strength. Page Authority measures individual page strength. Neither is a Google metric, but both correlate well with ranking ability. Page-level metrics matter for link placement - a link from a high-traffic, highly-linked page on a DR 50 site outperforms a link from a buried page on a DR 80 site.

Referring domains vs. total backlinks - Total backlinks count every link including multiple links from the same domain. Referring domains counts unique linking sites. Referring domains is the more meaningful growth metric - getting 100 links from one site has diminishing returns compared to links from 100 different sites.

Anchor text distribution - Healthy profiles contain: branded anchors (your company or domain name), naked URL anchors (just the URL), partial-match anchors (keyword phrase with other words), generic anchors ("click here", "read more"), and a small proportion of exact-match anchors (the target keyword verbatim). Profiles dominated by exact-match anchors are a red flag.

Common tasks

Create a digital PR campaign for linkable assets

Linkable assets are content pieces specifically designed to earn editorial coverage.

1. Choose an asset type based on what earns links in your niche:

   • Original research or survey data (journalists love citing statistics)
   • Free tools, calculators, or interactive resources
   • Comprehensive guides or studies journalists reference
   • Infographics with proprietary data
   • Industry reports with original findings

2. Identify target publications using Ahrefs Content Explorer or BuzzSumo to find journalists and sites that have already linked to similar content in your niche.

3. Build a press list with direct journalist email contacts (Hunter.io, LinkedIn, byline searches). Aim for journalists who cover your topic, not general press lists.

4. Write personalised pitches - reference the journalist's recent work, explain the data angle in the subject line, and keep the pitch under 150 words. Link to the asset; do not attach files.

5. Follow up once after 4-5 business days. More than one follow-up hurts deliverability and reputation.

See references/link-tactics.md for full digital PR playbooks and email templates.

Write HARO/Connectively pitches

HARO (now Connectively) connects journalists seeking expert sources with contributors. Response time is critical - most queries fill within 60 minutes of publication.

1. Set up alerts for your categories (Business & Finance, Technology, etc.)
2. When a relevant query arrives, respond within 60 minutes
3. Structure your pitch: credentials in one line, direct answer to the specific question, quotable soundbite (1-2 sentences), offer to elaborate

A strong pitch answers the journalist's specific question exactly. Do not add marketing language, multiple links, or off-topic context.

See references/link-tactics.md for HARO pitch templates and response frameworks.

Execute broken link building

Broken link building replaces a dead link on someone's page with a working link to your equivalent content.

1. Find broken links - Use Ahrefs Site Explorer on competitor domains or target resource pages, filter for 404 outbound links. Or use the Check My Links Chrome extension on resource pages manually.

2. Qualify opportunities - The page linking out must have real traffic and authority. The dead link's topic must match content you have (or can create).

3. Create or map replacement content - If you don't have equivalent content, create it before outreach. The replacement must be genuinely better than what was linked.

4. Outreach - Contact the page owner. Lead with value: inform them of the broken link (they'll thank you), then offer your content as a replacement. No hard sell.

See references/link-tactics.md for full broken link outreach email templates.

Plan guest posting strategy

Guest posting earns a link by contributing an article to another site.

1. Find relevant sites - Search [niche] + "write for us" or [niche] + "guest post guidelines". Use Ahrefs to check DR and organic traffic before approaching. Reject sites with obvious paid-link signals (e.g., "sponsored post" labels, link farms, irrelevant guest posts).

2. Qualify the site - Check that it has genuine organic traffic (not just DR), real editorial standards, and topical relevance to your domain.

3. Pitch the article idea first - Send a short pitch with 2-3 headline options relevant to their audience. Do not write the article before the pitch is accepted.

4. Write for their audience - The article's value is in the content, not your link. Place your link naturally in context where it provides genuine value to the reader. One link per post is the norm; two is acceptable if highly relevant.

5. Avoid link farms - Sites that accept any guest post without editorial review, have no topical focus, or have a "write for us" page that promises a "dofollow link" are red flags. Links from these sites carry little value and risk penalty.

Audit a backlink profile for toxic links

1. Export your full backlink profile from Ahrefs, Semrush, or Google Search Console
2. Flag links matching these toxic signals:
   • Domains with spam scores above 60% (Moz) or very low trust flow (Majestic)
   • Links from sites in unrelated niches (gambling, pharma, adult for non-related sites)
   • Mass anchor text patterns (hundreds of exact-match links from the same text)
   • Sitewide footer or sidebar links from low-quality sites
   • Links from known PBN patterns (thin content, multiple domains pointing to same IP)
3. Segment flagged links into: ignore, contact for removal, or disavow
4. Attempt manual removal for the worst offenders before disavowing

See references/link-audit.md for the full audit process, scoring criteria, and disavow file creation.

Create a disavow file

A disavow file tells Google to ignore specific backlinks when evaluating your site.

Format:

# Disavow file for example.com - Last updated 2025-01-15
# Toxic domains identified in Jan 2025 audit
domain:spam-site-example.com
domain:another-bad-domain.net
https://specific-page.com/specific-bad-link

• Prefer domain: entries over individual URL entries for efficiency
• Upload via Google Search Console under the Disavow Links tool
• Only disavow clear spam - do not disavow legitimate links or links you simply didn't earn yourself

See references/link-audit.md for full disavow guidance and when not to disavow.

Analyze competitor link profiles for opportunities

1. Enter a top-ranking competitor URL into Ahrefs Site Explorer
2. Go to Backlinks report - filter by DR 40+, dofollow, one link per domain
3. Look for patterns: resource pages, roundups, directory listings, mentions in studies or guides
4. Identify link types you can replicate: if competitors were linked from a niche directory or resource page, you can pitch those same pages
5. Run the same analysis on 3-5 competitors and merge the lists
6. Prioritize by: topical relevance, page traffic, ease of replication

Anti-patterns / common mistakes

Gotchas

1. DR/DA metrics are easily gamed - Domain Rating (Ahrefs) and Domain Authority (Moz) are third-party estimates, not Google metrics. Link farms actively inflate these scores with cross-linking schemes. Always verify organic traffic in Ahrefs/Semrush before targeting a site - a DR 60 site with 500 monthly organic visitors is worthless for link equity.

2. Disavowing legitimate links causes ranking drops - Over-disavowing is a real risk. Disavowing a genuine editorial link (even from a slightly spammy-looking site) removes that link's equity permanently. Only disavow links you are confident are either manipulative or from clearly deindexed/penalized domains.

3. HARO pitches need to land in the journalist's inbox within minutes, not hours - Most queries receive 50-200 responses. Journalists read the first batch that arrive and stop when they have their sources. A 4-hour response time is effectively no response. Set up email filters and push notifications; otherwise the platform is useless.

4. Anchor text diversification requires active monitoring, not just upfront planning - Your anchor text profile is shaped by how other sites link to you, not just what you ask for. Run quarterly anchor audits in Ahrefs and flag exact-match ratios above 15-20% of your total followed link profile before they become a pattern Google notices.

5. Broken link building yield is lower than it appears - Finding a broken link on a relevant resource page does not mean the webmaster will replace it with your link. Response rates of 5-10% are typical. Scale the outreach list accordingly; working from a short list of 20 opportunities is not enough to see meaningful results.
