How to Do Link Building: 12 Tactics (2026)

Why It Matters

Why do backlinks still matter in 2026?

Backlinks are votes of confidence from one website to another. Google’s ranking system uses them as one of its strongest signals for determining which pages deserve to rank. Despite years of algorithm updates, the correlation between backlinks and rankings has held steady. Pages in Google’s top 10 results have 3.8x more backlinks than pages ranking below them, according to Backlinko’s analysis of 11.8 million search results (updated 2025).

Link building is the practice of acquiring hyperlinks from external websites to your own, with the goal of improving search engine rankings, referral traffic, and domain authority.

The data tells a clear story. An astonishing 95% of all web pages have zero backlinks pointing to them (Ahrefs, 2025). For pages that do rank in the top 100, 92.3% have at least one backlink. The gap between “has links” and “doesn’t have links” is the gap between visibility and obscurity. But raw link count stopped being the metric that matters years ago. In 2026, Google evaluates links on relevance, trust signals, and entity associations. A single link from a topically relevant, high-authority publication moves the needle more than 500 links from unrelated directories. Link building cost has increased 20-35% since 2022, according to Editorial.link’s survey of 518 SEO professionals, driven by AI content saturation and stricter editorial standards at publishing sites. What hasn’t changed: 78% of marketers say link building delivers positive ROI, and 89.2% of SEOs see a ranking lift within 1-6 months of acquiring quality links (PressWhizz, 2025). The tactic works. The execution just requires more skill than it did five years ago.

Metrics

What metrics should you track for link building?

Not all links carry the same weight. Before you start building, you need to know how to measure what you’re getting. The two industry-standard metrics are Moz’s Domain Authority (DA) and Ahrefs’ Domain Rating (DR). Neither is a Google ranking factor, but both correlate with ranking performance and give you a quick way to assess link quality.

Metric	Source	What it measures	Best for
Domain Authority (DA)	Moz	Overall ranking potential based on link profile, domain age, and multiple signals	Competitive analysis, prospecting
Domain Rating (DR)	Ahrefs	Backlink profile strength based on linking domains	Link quality assessment, outreach targeting
Referring Domains	Ahrefs / Semrush	Number of unique websites linking to you	Growth tracking, diversity assessment
Trust Flow	Majestic	Quality of links based on link neighborhood	Spam detection, quality filtering
Anchor Text Distribution	Any backlink tool	The text used in links pointing to you	Natural vs. manipulated profile detection
Link Velocity	Ahrefs / Semrush	Rate of new links acquired over time	Campaign monitoring, competitor tracking

DA and DR both use a 0-100 logarithmic scale. Moving from DA 20 to DA 30 is significantly easier than moving from DA 50 to DA 60. The logarithmic nature means each point gets harder to earn as you climb. For practical prospecting, we target sites with DA 40+ and DR 30+ for link placements. Below those thresholds, the link equity passed is minimal. Above DA 60, you’re typically looking at major publications that require digital PR, not email outreach. The metric that matters most for your own site is referring domains, not total backlinks. Having 200 links from 200 different websites is far more valuable than 200 links from 3 websites. Google values diversity of linking sources.

12 Tactics

Which link building tactics actually work right now?

These 12 tactics are what we use across client engagements at ScaleGrowth.Digital. They’re ordered roughly by effort level, from quickest wins to longer-term plays. No single tactic is sufficient on its own. The strongest link profiles come from mixing multiple approaches.

1. Unlinked Brand Mention Reclamation

If someone mentions your brand, product, or founder name without linking, you have a warm outreach opportunity. Set up Google Alerts or use Ahrefs’ Content Explorer to find mentions. A short, friendly email asking for a link converts at 15-25% because the site already knows and trusts you. This is the lowest-effort, highest-conversion tactic available.

2. Broken Link Building

Find pages in your niche that link to dead URLs (404s). Create content that covers the same topic, then email the site owner: “Hey, I noticed your link to [dead URL] is broken. We have a resource that covers the same topic if you’d like to update it.” Tools like Ahrefs’ Broken Backlinks report make finding these opportunities fast. Conversion rates typically run 5-10%.

3. Guest Posting on Relevant Publications

Guest posting works in 2026 when done correctly. The goal isn’t placing a link. It’s contributing genuinely useful content to a relevant audience. Target publications your actual audience reads. Write for them the same way you’d write for your own site. One well-placed guest post on a DA 60+ site can pass more equity than 20 directory listings. Avoid guest post farms or sites that accept anything.

4. Digital PR and Data-Driven Content

Create original research, surveys, or data analyses that journalists want to cite. Digital PR is one of the cleanest ways to earn high-authority links because it aligns with how the web naturally works: you create something newsworthy, journalists cover it, and links follow. We’ve earned links from DA 80+ publications by running industry surveys with sample sizes of 500+ respondents.

5. The Skyscraper Technique

Find content that’s already earning backlinks, create something meaningfully better, then reach out to sites linking to the original. “Meaningfully better” means more current data, better visuals, deeper analysis, or additional sections. Don’t just make it longer. Make it more useful. This technique, popularized by Brian Dean at Backlinko, still converts when the content improvement is obvious.

6. Resource Page Link Building

Many sites maintain resource pages or “best tools” lists in your niche. If you have a relevant tool, template, or guide, pitch it for inclusion. Search operators like intitle:"resources" + [your keyword] or intitle:"useful links" + [your industry] help you find these pages. Conversion rates are 5-15% depending on how relevant your resource is.

7. HARO / Connectively / Quoted.ai

Help A Reporter Out (now Connectively) connects journalists with expert sources. You respond to journalist queries with expert commentary, and if selected, you get a link from the publication. Response speed matters. Journalists often use the first 3-5 quality responses they receive. Set up filters for your expertise areas and respond within 2 hours of a query going live.

8. Podcast Guesting

Getting interviewed on industry podcasts earns you a link from the show notes page, plus the credibility signal of being an invited expert. Most podcast hosts include guest bios with website links. Target podcasts in your niche with 50+ episodes (a sign of commitment and audience). Pitch a specific topic, not a generic “I’d love to be on your show.”

9. Creating Linkable Assets

Build resources so useful that people link to them without you asking. Free tools, calculators, templates, original research, and comprehensive guides all qualify. Our marketing ROI calculator and SEO checklist earn links passively because they’re genuinely useful. The investment is high upfront, but these assets compound.

10. Competitor Backlink Analysis

Use Ahrefs or Semrush to pull your competitors’ backlink profiles. Filter for links from DA 40+ sites. Many of these same sites will link to you if you offer similar or better content. This works especially well for discovering niche directories, industry associations, and publications you hadn’t considered. We call this “gap analysis outreach.”

11. Infographics and Visual Assets

Data visualizations and infographics still earn links when they present original data clearly. The key is original data, not a visual wrapper around generic facts. Create an infographic based on your own survey, client data (anonymized), or a unique analysis. Offer an embed code so other sites can easily place it with attribution. Long-form content (3,000+ words) receives 77.2% more backlinks than short-form (Backlinko, 2025), and visual assets amplify that further.

12. Strategic Partnerships and Co-Marketing

Partner with complementary (not competing) businesses on co-created content. Joint webinars, co-authored research reports, and shared tools all generate natural cross-linking. Each partner promotes to their audience, multiplying distribution. We’ve built partnerships where a single co-authored industry report earned 40+ referring domains for both parties within 3 months.

Outreach

How do you structure link building outreach?

Link building outreach fails when it feels like spam. It works when it feels like a genuine, relevant suggestion. The difference is personalization and relevance. Here’s the outreach process we run at ScaleGrowth.Digital for every client campaign. Step 1: Build your prospect list. Use Ahrefs, Semrush, or Moz to find sites linking to competitors but not to you. Filter for DA 40+ and topical relevance. Export 50-100 prospects per campaign cycle. Step 2: Find the right contact. Don’t email info@ or contact forms. Find the author of the article you’re targeting, the editor of the blog, or the webmaster. Tools like Hunter.io and Apollo help locate email addresses. LinkedIn works for smaller publications. Step 3: Personalize every email. Reference a specific article they wrote. Mention something specific about their site. Show you’ve actually visited their site. Generic templates convert at 1-2%. Personalized outreach converts at 8-15%. Step 4: Follow up once. Send one follow-up 5-7 days after the initial email. Don’t follow up more than once. If they’re not interested after two touches, move on. Aggressive follow-up sequences damage your brand reputation. Step 5: Track everything. Use a spreadsheet or CRM to track prospects, email status, response, and outcome. Measure response rate, conversion rate, and average DA of links earned per month. Without tracking, you can’t optimize.

What to Avoid

What link building tactics should you avoid?

Google’s spam policies are explicit about what constitutes link manipulation. Getting caught results in manual penalties that can take months to recover from. These tactics are not worth the risk.

Buying links: Paying for links that pass PageRank violates Google’s guidelines. This includes paying for guest posts on low-quality sites, PBN (Private Blog Network) links, and link packages from Fiverr or similar platforms.
Link exchanges at scale: “I’ll link to you if you link to me” done systematically is detectable and penalizable. Occasional natural reciprocal links are fine. Organized link swaps are not.
PBN links: Private Blog Networks are sets of websites created solely to build links. Google’s SpamBrain algorithm has become extremely effective at detecting these networks.
Comment spam and forum spam: Dropping links in blog comments, forum signatures, and user profiles provides zero SEO value in 2026. Most are nofollowed, and the ones that aren’t flag your profile as spammy.
Automated link building tools: Any tool that promises “thousands of backlinks” is building spam. These tools submit your site to low-quality directories, article spinners, and web 2.0 properties en masse.
Irrelevant guest posts: Publishing a dental article on a tech blog just for the link is obvious to both Google and readers. Topical relevance between the linking and linked site matters.

94% of link builders say quality matters more than quantity (DemandSage, 2026). This isn’t just a best practice opinion. It’s a risk management decision. One manual penalty from Google can wipe out years of organic growth.

Pro Tips

Pro tips from our link building practice

Track link velocity, not just link count. A steady rate of 10-20 new referring domains per month looks natural to Google. A spike of 200 links in one week followed by silence looks purchased. Consistency beats bursts.
Anchor text diversity matters. If 70% of your backlinks use your exact target keyword as anchor text, that’s a manipulation signal. Natural profiles have a mix: branded anchors (40-50%), naked URLs (20-30%), generic (“click here,” “this article”) (15-20%), and keyword-rich (10-15%).
Link to your best content, not your homepage. Deep links to specific guides, tools, or data pages are more valuable than homepage links. They pass relevance signals directly to the page you want to rank.
Build relationships before you need links. Share people’s content on social media. Comment thoughtfully on their articles. Attend the same conferences. When you eventually reach out for a link, you’re not a stranger.
Set realistic expectations. A new site can expect to earn 5-15 quality links per month with dedicated effort. Moving DA from 15 to 30 typically takes 6-12 months. From 30 to 50 takes another 12-18 months. There are no shortcuts that don’t carry penalties.

Common Mistakes

Common link building mistakes

Prioritizing quantity over relevance. Ten links from relevant industry sites will outperform 100 links from random directories. Every time. Filter your prospect list by topical relevance first, DA second.
Ignoring internal links while chasing external ones. External links bring authority into your site. Internal links distribute that authority to the pages that need it. Neglecting internal linking means your externally-earned equity gets stuck on a few pages instead of flowing to the pages you want to rank.
Not disavowing toxic links. If you discover spammy sites linking to you (especially from negative SEO attacks or legacy link building), use Google’s Disavow Tool. Leaving thousands of spam links unchecked can suppress your rankings.
Sending identical outreach emails. Mass templates get mass-deleted. If your outreach email could have been sent to any website without changing a word, it will be ignored. Spend 3 minutes personalizing each email. It doubles your response rate.
Quitting too early. Link building compounds over time, but the early months feel slow. Most teams give up at month 3. The teams that push to month 6-12 see exponential returns as domain authority grows and each new link carries more weight.

FAQ

Frequently Asked Questions

How many backlinks do you need to rank on the first page?

There’s no fixed number. Pages in Google’s top 10 have 3.8x more backlinks than lower-ranking pages (Backlinko, 2025), but the actual number depends on your niche’s competitiveness. A local service keyword might need 10-20 referring domains. A competitive national keyword might need 200+. Use Ahrefs or Semrush to check how many referring domains your top-5 competitors have for your target keyword, and use that as your benchmark.

How long does it take for backlinks to affect rankings?

Most SEOs see a ranking lift within 1-6 months of acquiring quality backlinks (PressWhizz, 2025). The timeline depends on the authority of the linking site, how quickly Google crawls it, and how competitive your target keyword is. High-authority links from frequently crawled sites (major publications, news sites) can show effects within weeks. Links from smaller sites may take 2-3 months to be fully processed.

Is link building still worth it in 2026?

Yes. 78% of marketers say link building delivers positive ROI (Editorial.link, 2025). Links remain one of Google’s top ranking signals. The tactics have shifted from volume-based approaches to quality-focused methods like digital PR, expert commentary, and original research. The cost has increased 20-35% since 2022, but the returns for quality link building have increased as well, because fewer competitors are doing it well.

What’s the difference between dofollow and nofollow links?

Dofollow links pass PageRank (link equity) and influence rankings. Nofollow links include a rel=”nofollow” attribute that tells Google not to pass equity. Since 2019, Google treats nofollow as a “hint” rather than a directive, meaning they may choose to count some nofollow links anyway. A natural backlink profile includes both types. Nofollow links from high-traffic sites can still drive valuable referral traffic even if they don’t directly affect rankings.

How much does link building cost?

Link building costs vary widely. DIY outreach costs only your time (5-10 hours per week for 10-15 links per month). Hiring a freelancer runs $500-$2,000 per month. Working with a specialized firm like ScaleGrowth.Digital costs $2,000-$10,000+ per month depending on volume and target authority levels. Individual link placements on DA 50+ sites typically run $150-$500 each when outsourced. The key cost driver is the authority level of the sites you’re targeting.
