A “link” refers to a hyperlink or URL connecting one web page. These links are essential for both user navigation and search engine rankings.
What Is a Link?
A link, or hyperlink, is a clickable element—typically text or an image—that directs users from one web page to another. It can point to a different page on the same website (internal link) or to a page on a completely different website (external link).
For example, linking from a homepage to a blog post is internal linking. Linking out to a source like Google’s SEO Starter Guide is external linking.
Links are fundamental to how the web functions. Search engines like Google use them to crawl, index, and rank content. They serve as pathways for both users and search bots.
If you’re unsure how internal linking affects your rankings, explore our internal links glossary article for a deeper explanation.
Why Links Matter in SEO?
Links are one of the most important ranking signals in Google’s algorithm. When one website links to another, it’s interpreted as a vote of confidence—a signal that the content being linked to is valuable, credible, and relevant.
This idea is rooted in Google’s original PageRank algorithm, which treated backlinks as endorsements. Although the algorithm has evolved, the core principle still applies: quality links drive authority.
Not all links are equal. A backlink from a high-authority domain (like Forbes or Moz) holds more weight than a link from a random blog. That’s why link building is such a core part of SEO strategies.
If you’re looking to assess the health and authority of your backlinks, our competitor link analysis service offers a strategic advantage by identifying gaps and opportunities.

Types of Links in SEO
Understanding the different types of links is key to building a strong SEO strategy. Each type serves a unique purpose and can impact rankings in different ways.
Dofollow vs. Nofollow
- Dofollow links pass authority (link equity) and can directly improve search rankings. These are the default link types unless specified otherwise.
- Nofollow links contain a rel=”nofollow” tag, signaling search engines not to pass authority. While they might not boost rankings directly, they still drive traffic and build credibility.
More on this in our nofollow and dofollow glossary entries.
Sponsored and UGC (User-Generated Content)
Google recommends using rel=”sponsored” for paid links and rel=”ugc” for user-submitted content, such as blog comments or forum posts. This keeps link intent transparent and avoids penalties.
You can learn more directly from Google’s link attribute documentation.
Editorial Links
These are the gold standard—earned naturally when others link to your content because they find it valuable. Our article on editorial links explains how to get more of them.
Anchor Variations
- Branded anchor: Uses the brand name (e.g., Shrushti Digital)
- Exact match: Uses the target keyword (e.g., “technical SEO audit”)
- Partial match or generic: Includes a mix of words (e.g., “check our guide here”)
Using a healthy mix keeps your backlink profile natural and avoids penalties related to over-optimization.
Internal Linking
Internal linking refers to hyperlinks that connect one page on a website to another page on the same domain. This structure helps both users and search engines navigate your site more effectively.
Why It Matters
Internal links distribute page authority, guide users to relevant content, and help search engines crawl and index more pages. They also play a key role in user engagement by reducing bounce rates and increasing time-on-site.
For instance, linking from a blog post to your technical SEO audit service or blog post optimization service guides users further down the funnel.
Best Practices
- Use descriptive anchor text (avoid “click here”)
- Link only when contextually relevant
- Prioritize high-performing or conversion-focused pages
- Don’t overdo it—too many links dilute value
For a practical breakdown, our post on page-wise SEO recommendations gives tips on where and how to internally link for the most SEO benefit.
You can also learn from Moz’s guide to internal links, which explores this topic from a technical standpoint.
Backlinks and Authority Building
Backlinks—links from other websites to yours—are one of the strongest indicators of a site’s authority. The more high-quality backlinks your site earns, the more credible it appears to both search engines and users.
Why Backlinks Matter?
Google uses backlinks as trust signals. When reputable sites link to you, it signals that your content is valuable. These “votes” boost your domain authority and can significantly improve rankings.
Our team at Shrushti helps agencies and brands acquire high-authority backlinks through white-label link building services and guest post services.
How to Earn Quality Backlinks?
- Publish unique, well-researched content
- Contribute guest articles to trusted publications
- Build relationships with industry influencers
- Create resources that others want to cite, like case studies or stats
A great resource to explore this further is the Ahrefs guide to backlinks, which explains both strategy and tactics in depth.
Additionally, you can read about real-life strategies in our Bamboo Ave SEO case study to see how backlinks drive growth in practice.
Link Building Strategies
Effective link building is more than just getting any link—it’s about earning links that are relevant, trusted, and placed in the right context. Google is smarter than ever, so spammy tactics no longer work.
Tried-and-Tested Methods
- Guest Posting
Contribute valuable content to relevant websites in your niche. It helps build brand awareness and earns you contextual backlinks. Check our guest post services if you need help scaling this. - Resource Pages & Link Roundups
Get your content listed on curated pages by reaching out to site owners who regularly feature helpful tools or blogs. - Broken Link Building
Find dead links on relevant websites and suggest your content as a replacement. Tools like Ahrefs or Screaming Frog can help identify these opportunities. - Link Bait Content
Create data-driven posts, tools, infographics, or unique insights that naturally attract links. Our content strategy company can help you develop content that earns links on its own merit. - Local Citations and Directories
Especially for local businesses, getting listed in relevant directories like Yelp or Google Business Profile boosts visibility. For support, check our local citation building services.
Avoid These Pitfalls

Google’s Spam Policies clearly outline what could get your site penalized.
Monitoring and Managing Links
Building links is just the beginning. Ongoing monitoring ensures your backlink profile remains healthy, free from spam, and aligned with Google’s quality guidelines.
Why Link Monitoring Matters?
Unnatural or toxic backlinks—like those from link farms or irrelevant sites—can harm your rankings. Regular audits help you spot and disavow harmful links before they trigger penalties.
You can explore how we handle this in our link audit service, which includes manual checks, anchor text review, and disavow file preparation.
Tools for Link Tracking
- Google Search Console: Offers a basic view of sites linking to yours.
- Ahrefs and SEMrush: Provide comprehensive link tracking, toxicity scores, and historical data.
- Shrushti’s SEO Dashboard: If you are one of our agency partners, we offer white-label reports that track link quality and growth over time. Learn more under white-label SEO dashboards.
If a bad link does make it through, use Google’s Disavow Tool responsibly. But be cautious—it’s a last resort, not a fix-all.
When to Take Action?
- Sudden spike in backlinks from shady domains
- Anchors unrelated to your content or brand
- Manual actions in Search Console
A consistent cleanup strategy keeps your SEO efforts secure and future-proof.
Links remain one of the most powerful ranking factors in Google’s algorithm—but quality always outweighs quantity.
Building a trustworthy, diverse backlink profile takes time. It involves smart content creation, strategic outreach, ongoing audits, and knowing when to disavow. Most importantly, it should align with your broader SEO goals—not just quick wins.
If you are struggling with this balance, consider hiring a link building expert to guide your strategy. Our team at Shrushti has helped businesses and agencies secure placements on top-tier publications while maintaining clean, penalty-free link profiles.
