What Is Link Building and Why Does It Matter?
Link building remains one of the most powerful yet misunderstood aspects of search engine optimization. Despite countless algorithm updates and the rise of AI-powered search, backlinks continue to serve as the web's primary trust signal--the digital equivalent of a recommendation from another website.
Link building is the process of acquiring hyperlinks from other websites to your own. These backlinks act like "votes of confidence" from other sites, signaling to search engines that your content is valuable and trustworthy.
How Search Engines Use Backlinks
Search engines crawl the web through links. When they discover a backlink pointing to your site, they follow it to your page, evaluate the linking domain's authority and relevance, and use that data to determine how much "link equity" or value to pass to your site. LinkyJuice's guide on link equity explains this process in detail.
The State of Link Building in 2025
Google's Helpful Content Update has fundamentally changed link building. Quality now trumps quantity, and spammy tactics no longer work--they can actually harm your rankings. The focus has shifted toward earning links through genuinely valuable content that demonstrates E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness). BuzzStream's analysis of post-update strategies shows how successful link builders have adapted.
For businesses looking to improve their search visibility, understanding modern link building is essential. Combined with our comprehensive SEO services, effective link building can significantly boost your organic rankings and drive qualified traffic to your website. Our web development team also ensures your site is technically optimized to maximize the value of every link you earn.
Understanding Link Quality and Metrics
Backlinks vs. Internal Links vs. External Links
Understanding the three types of links is fundamental to an effective SEO strategy:
- Backlinks (incoming links): Links from other websites pointing to your site. These are the primary focus of link building efforts.
- Internal links: Connections between pages on your own website. These help users navigate your site and distribute link equity throughout your content.
- External links (outbound): Links from your website to other domains. When used naturally, they build context and credibility with both users and search engines.
A comprehensive SEO strategy incorporates all three link types strategically. While backlinks from external sources build authority, internal linking ensures that authority flows to your most important pages.
Domain Rating vs. Domain Authority
Domain Rating (DR), developed by Ahrefs, and Domain Authority (DA), created by Moz, both estimate a website's backlink profile strength. While useful for evaluating link opportunities, these are third-party metrics--not actual Google ranking factors. LinkyJuice's explanation of DR vs DA clarifies how to use these metrics appropriately.
A backlink from a smaller, highly relevant niche website often delivers more value than a random high-DR link with no connection to your industry. When evaluating link prospects, prioritize relevance and raw metric scores.
Anchor Text: The Clickable Signal
Anchor text is the clickable keyword or text in a hyperlink. Google pays close attention to anchor text when determining page relevance. LinkyJuice's anchor text guide outlines the various types and their SEO implications.
Types of anchor text include:
- Branded: Your company name (e.g., "Digital Thrive")
- Exact match: Target keyword exactly (e.g., "SEO services")
- Partial match: Includes keyword variation (e.g., "professional SEO services")
- Generic: Vague phrases like "click here"
- Naked URL: The raw URL as anchor
The key is maintaining a natural distribution. Over-optimization with exact-match anchors can trigger algorithmic penalties, so vary your anchor text to match what organic linking patterns would naturally produce. Our SEO specialists can help you develop an anchor text strategy that balances keyword targeting with natural diversity.
Core Link Building Strategies
Foundational Links: Building Your Base
Every new website needs foundational links to establish credibility. These include:
- Google Business Profile: Essential for local SEO and discoverability
- LinkedIn Company Page: Professional credibility signal for B2B audiences
- Social Media Profiles: Brand presence across relevant platforms
- Industry Directories: Relevant, trusted listings in your niche
These foundational links help search engines understand what your business is about and establish initial trust signals. Sendible's link building guide emphasizes starting with these quality foundations. When building a new website, our web development experts ensure these foundational elements are properly implemented from day one.
Guest Posting and Contributor Writing
Guest posting remains an effective link building strategy when done correctly. The key is providing genuine value to the host site's audience while earning contextual links back to your content. Sendible's guest posting best practices outline how to approach this tactic effectively.
Best practices for guest posting:
- Target relevant, high-quality publications in your niche
- Pitch unique angles that haven't been covered extensively
- Create genuinely helpful, well-researched content
- Include links that genuinely add value for readers
- Build relationships with editors for ongoing opportunities
Avoid low-quality article submission sites and focus on publications where your target audience actually consumes content.
The Skyscraper Technique
The Skyscraper Technique, popularized by Brian Dean, involves finding link-worthy content in your niche and creating something significantly better. Sendible's technique breakdown provides implementation details.
Steps to execute:
- Find popular content with many backlinks using tools like Ahrefs or BuzzSumo
- Create an improved version with more depth, updated information, and better design
- Reach out to sites linking to the original content
- Suggest they link to your improved resource instead
This technique works because you're solving a genuine problem--outdated or incomplete content--for site owners who want to provide their readers with the best resources.
Broken Link Building
Broken link building is a "win-win" strategy where you find broken links on relevant pages and offer your content as a replacement. Sendible's broken link building guide explains the methodology.
Process:
- Find broken links on authoritative pages in your niche using tools like Screaming Frog
- Create or identify content that serves as a good replacement
- Contact the site owner or editor with a polite replacement suggestion
- Provide value by helping them maintain a quality user experience
This approach is so effective because you're genuinely helping website owners fix a problem while earning a link in the process.
Resource Page Link Building
Many websites maintain curated resource pages linking to valuable tools and information in their industry. Getting featured on these pages can provide quality backlinks and ongoing referral traffic.
How to approach resource page link building:
- Identify relevant resource pages in your industry through targeted searches
- Create genuinely useful resources worthy of inclusion
- Reach out with a brief, value-focused pitch
- Follow up respectfully if you don't hear back initially
Resource page links tend to be stable and relevant, making them valuable for long-term SEO success.
The most sustainable link building comes from creating content that others want to link to without being asked.
Original Research and Data Studies
Unique data and insights that journalists and bloggers cite as authoritative sources. Original research earns high-quality editorial links naturally.

What Makes Content Newsworthy
- Original research: Data studies and surveys that reveal new industry insights

Expert Positioning and Quote Pitching
Positioning yourself as an expert source is one of the most efficient ways to earn quality links. Platforms like HARO (Help A Reporter Out) connect experts with journalists seeking sources. BuzzStream's expert positioning strategies detail how to succeed on these platforms.
Tips for successful expert pitching:

Internal Link Building: Maximizing Your Existing Link Equity
While backlinks from other sites are crucial, internal linking maximizes the value of links you already have. Strategic internal linking helps distribute page authority throughout your site. Sendible's internal linking strategies explain best practices.
Internal links help search engines discover and understand your content hierarchy while guiding users to relevant resources. A strong internal linking structure amplifies the impact of your external link building efforts. When combined with our AI-powered automation services, you can scale content creation to support your link building efforts efficiently.
Internal Linking Best Practices
- Create logical navigation pathways that mirror user intent
- Use descriptive, keyword-relevant anchor text for internal links
- Link from high-authority pages to priority content that needs a ranking boost
- Ensure important pages are no more than 3 clicks from the homepage
- Avoid orphan pages with no internal links connecting them to the rest of your site
- Update content with new internal links when you acquire backlinks to related pages
Combining content marketing services with strategic internal linking creates a powerful SEO ecosystem where every piece of content supports and amplifies others.
