how to build seo authority using backlinks

You have optimized your on-page SEO, published high-quality content, and fixed technical site issues, but your site still is not ranking on page 1 of Google. The missing piece is almost always SEO authority. SEO authority measures how trustworthy search engines deem your website, and backlinks remain one of the top three ranking factors Google uses to evaluate that trust. Learning how to build seo authority using backlinks is the difference between page 10 and page 1 rankings for competitive keywords.

Backlinks act as votes of confidence from other websites. When a reputable site links to your content, it signals to search engines that your site is a reliable resource in your niche. Not all backlinks are created equal, though. Low-quality, spammy links can hurt your rankings, while high-quality, relevant links will grow your authority steadily over time.

This guide will walk you through proven, white hat strategies to build SEO authority with backlinks. You will learn how to audit your existing backlink profile, create content that attracts links naturally, execute targeted outreach campaigns, and avoid common penalties. We will also share a real-world case study, a step-by-step action plan, and recommended tools to streamline your efforts.

What Is SEO Authority, and Why Do Backlinks Drive It?

SEO authority is a score that measures how trustworthy and ranking-worthy search engines consider your website. While Google does not use third-party metrics like Moz’s Domain Authority (DA) directly, Google’s algorithm evaluates similar trust signals, including expertise, experience, authoritativeness, and trustworthiness (E-E-A-T). A site with high SEO authority will outrank a lower-authority site with identical on-page optimization for the same keyword.

Backlinks are the primary driver of SEO authority because they act as independent endorsements. When a reputable website links to your content, it vouches for the quality and accuracy of your information. For example, a local roofing company with DA 48 will rank #3 for “roof repair Chicago” over a competitor with DA 12 and identical on-page SEO, simply because of its higher authority from quality backlinks.

Short answer: What is SEO authority? SEO authority is a search engine or third-party assigned score that measures your website’s trustworthiness and ability to rank for competitive keywords, driven primarily by backlink quality, content expertise, and user trust signals.

Start by establishing a baseline for your current authority. Use our free domain authority checker to view your current DA, total backlinks, and referring domains. This will help you track progress as you execute your link building strategy.

Common mistake: Obsessing over third-party DA scores instead of Google’s actual trust signals. A site with DA 30 that is highly relevant to your niche and has consistent user engagement is more valuable than a DA 60 site with spammy content and no real traffic.

The Core Rules of High-Quality Backlinks

Not all backlinks contribute to SEO authority. Google’s spam policies explicitly penalize manipulative link building tactics, so following core quality rules is non-negotiable. Every backlink you earn must meet three criteria: relevance, authority of the linking site, and natural placement.

3 Non-Negotiable Backlink Quality Rules

• Relevance: Linking site must be related to your niche or the topic of the linked content.
• Authority: Linking site must have DA 40+ and real organic traffic.
• Natural Placement: Link must be embedded contextually in body content, not footers or sidebars.

Relevance means the linking site is related to your industry or the topic of the content being linked. For example, a backlink from a marketing blog to a digital marketing agency is relevant, while a backlink from a gambling site to the same agency is not. Authority refers to the trustworthiness of the linking site, measured by its own backlink profile and traffic.

Short answer: What makes a backlink high quality? A high-quality backlink comes from a relevant, authoritative website, uses natural anchor text, is placed contextually in body content, and is part of a natural link profile mix of dofollow and nofollow links.

Always prioritize link quality over quantity. Ten backlinks from DA 40+ relevant sites will grow your authority faster than 100 backlinks from DA 10 spam sites. You can evaluate linking site authority using Moz’s Domain Authority tool before pursuing a link.

Common mistake: Chasing high DA sites that are completely unrelated to your niche. A backlink from a DA 80 news site for a niche knitting blog adds little authority value, even if the DA is high.

Create Link-Worthy Content: The Foundation of Authority Growth

You cannot build SEO authority with backlinks if no other site wants to link to your content. Link-worthy content, also called linkable assets, is content that provides unique value no other page offers. Common types of linkable assets include original research, ultimate guides, free tools, and data-driven reports.

For example, HubSpot’s annual State of Marketing report earns thousands of backlinks every year because it provides proprietary data that marketers cannot find anywhere else. A small business can create similar linkable assets by surveying their customers, compiling industry statistics, or building a free tool like a mortgage calculator for a real estate site.

Actionable tip: Create one linkable asset every quarter. Promote it to your email list and social media followers first, then use it as the basis for outreach campaigns. Pair this with our content marketing for SEO strategy to maximize reach.

Common mistake: Creating “me too” content that is identical to top-ranking pages. If your guide to SEO tips is exactly the same as 10 other guides already ranking, no site has a reason to link to you over them.

Use the Skyscraper Technique to Outrank Competitors

The Skyscraper Technique is a proven link building strategy developed by Brian Dean of Backlinko. It works by finding top-performing content in your niche, creating a better version of that content, then reaching out to sites that link to the original to suggest your improved version.

4 Steps to Execute the Skyscraper Technique

1. Find top content with 100+ backlinks in your niche using Ahrefs.
2. Improve it by adding more value, fresh 2024 data, or better design.
3. Export all backlinks to the original content using Ahrefs.
4. Send personalized outreach to each linking site offering your updated version.

For example, if the top-ranking guide for “small business marketing tips” has 10 tips and was published 2 years ago, you could create a guide with 20 updated tips, add original data, and include better visuals. You then use a tool like Ahrefs to find all sites linking to the original guide, and send a personalized outreach email: “Hi, I loved your post linking to [original guide]. I just published an updated, more comprehensive version here [your link] that includes 2024 data. Might be useful for your readers!”

Common mistake: Not improving the content enough. Simply copying the original guide and adding one paragraph of new content will not convince site owners to switch their links to your page.

Leverage Unlinked Brand Mentions for Quick Wins

Unlinked brand mentions are instances where a website mentions your brand name, product, or founder but does not include a link back to your site. These are low-hanging fruit for backlink building because the site already knows who you are and has a positive impression of your brand.

For example, a food blogger might write a post saying “I used Scale SEO’s content marketing strategy to grow my traffic by 50%” but forget to link to your site. You can reach out to the blogger: “Hi, loved your recent post! Thank you for mentioning Scale SEO. Could you add a link to our site so your readers can learn more about the strategy you used? Thanks!” Most site owners will happily add the link.

Actionable tip: Use Google Alerts or Ahrefs Brand Alerts to monitor mentions of your brand name, product names, and founder names. Check for new mentions weekly to catch opportunities quickly.

Common mistake: Being pushy or demanding in outreach emails. Keep requests short, polite, and focused on helping the site owner’s readers, not just your own link building goals.

Build Authority with Guest Blogging (The Right Way)

Guest blogging remains one of the most effective ways to build SEO authority with backlinks when done correctly. The key is to target high-quality, relevant sites that have real traffic, not “guest post farm” sites that accept any content for a fee.

For example, a SaaS company that sells project management software could guest post on a marketing blog with DA 50, writing a unique post about “How to Use Project Management Tools to Streamline Content Calendars”. The post includes a contextual dofollow link back to the SaaS company’s pricing page, earning a high-quality backlink and referral traffic.

Actionable tips: Only pitch unique content ideas that have not been covered on the site before. Avoid over-optimizing anchor text: use branded anchors like “Scale SEO” or generic anchors like “click here” instead of exact-match keywords. Limit guest posting to 1-2 posts per month per site to keep your link profile natural.

Common mistake: Guest posting on low-quality sites that exist only to sell backlinks. Google penalizes both the guest poster and the site for this tactic, which can wipe out your SEO authority entirely.

Broken Link Building: Reclaim Lost Link Value

Broken link building involves finding broken links on relevant websites, creating content that replaces the broken resource, and reaching out to the site owner to suggest your content as a replacement. This strategy works because site owners want to fix broken links to improve user experience, so they are often happy to update the link.

For example, a web design blog might have a resource page linking to a 404 page about “free web design tools”. You could create an updated list of free web design tools, then reach out to the blog owner: “Hi, I noticed your resource page links to a broken page for free web design tools. I just published an updated list here [your link] that includes all the latest tools. Might be a good replacement!”

Actionable steps: Use Ahrefs Broken Link Checker to find broken links on sites in your niche. Filter for links related to your content topics. Reach out to site owners with a polite, concise email offering your replacement content.

Common mistake: Offering irrelevant content as a replacement. Only suggest content that is a direct match for the broken resource, or site owners will ignore your outreach.

Partner with Publications via HARO for High-Authority Links

Help a Reporter Out (HARO) is a free platform that connects journalists and bloggers with industry experts. Reporters send out queries for expert sources, and you can respond with insights to be quoted in their articles. If you are selected, you typically earn a backlink from a high-authority news or industry site.

For example, a personal finance expert might respond to a HARO query for “top budgeting tips for college students” from a reporter at U.S. News & World Report. The expert is quoted in the article, with a link back to their personal finance blog. This earns a high-authority backlink and exposure to a large new audience.

Actionable tips: Sign up for HARO as a source, and set alerts for queries related to your niche. Respond to queries within 2 hours of posting, as reporters work on tight deadlines. Keep responses concise, 2-3 paragraphs, with clear, actionable insights.

Common mistake: Sending generic, copy-pasted pitches to every query. Reporters receive hundreds of pitches, so personalized, relevant responses are the only ones that get selected.

Resource Page Link Building: Target Curated Industry Lists

Resource pages are curated lists of helpful links on a specific topic, created by industry sites to provide value to their readers. These pages are highly relevant, so earning a spot on a resource page is a great way to build SEO authority with backlinks.

For example, a freelance writer could search for “freelance writing resources” and find a DA 45 blog with a resource page linking to top writing tools, job boards, and guides. The writer could reach out to the blog owner: “Hi, I love your freelance writing resource page. I just published a guide to pitching freelance clients that would be a great addition to your list. You can view it here [your link].”

Actionable steps: Search Google for “[your niche] + “resource page” + “links” to find relevant resource pages. Evaluate the page’s authority and how recently it was updated. Reach out to the site owner with a short pitch offering your content.

Common mistake: Targeting resource pages that have not been updated in 3+ years. These pages are less likely to be actively maintained, so site owners may not respond to your outreach.

High-Quality vs Low-Quality Backlinks

Distinguishing between high-quality and low-quality backlinks is critical to avoid penalties and grow SEO authority. The table below outlines the key differences between the two, based on Google’s spam policies and Ahrefs backlink research.

Regularly audit your backlink profile to remove low-quality links. Use Google Search Console to identify spammy links, and disavow them if necessary using the Google Disavow Tool.

Nofollow vs Dofollow Backlinks: Do You Need Both?

Dofollow backlinks pass authority from the linking site to your site, directly contributing to SEO authority growth. Nofollow backlinks include a tag that tells search engines not to pass authority, but they still provide value. A natural link profile includes a mix of both dofollow and nofollow links.

For example, a link from a New York Times article about your business will likely be nofollow, but it still drives high-value referral traffic and signals to Google that your brand is noteworthy. A link from a niche blog’s body content will typically be dofollow, passing direct authority.

Short answer: Do nofollow backlinks help with SEO authority? Nofollow backlinks do not pass direct authority, but they contribute to a natural, trustworthy link profile and can drive referral traffic that improves user engagement signals, indirectly boosting rankings.

Actionable tip: Do not turn down a nofollow link from a high-authority, relevant site. The referral traffic and brand exposure are valuable, even if no authority is passed directly.

Common mistake: Only pursuing dofollow backlinks. A 100% dofollow link profile looks unnatural to Google, and can trigger a manual review or penalty.

Common Mistakes to Avoid When Building SEO Authority with Backlinks

Even with the best intentions, it is easy to make mistakes that hurt your SEO authority. Below are the most common errors to avoid:

• Buying backlinks from Fiverr or link farms: This is a direct violation of Google’s spam policies, and almost always results in a penalty that wipes out your rankings.
• Over-optimizing anchor text: Using exact-match keywords for 50%+ of your anchor text looks manipulative. Stick to 10% or less exact-match anchor text.
• Ignoring your backlink profile: Spammy sites may link to you without your permission. Monitor your backlinks monthly and disavow harmful links.
• Building links from unrelated niches: A link from a pet store to a law firm adds no authority value, and may be flagged as spam.
• Using automated link building tools: Tools that auto-generate backlinks create low-quality, spammy links that will hurt your authority.

Reference Google’s official spam policies to ensure all your link building tactics are compliant.
