# What Is Link Building?

Link building is the process of earning backlinks from other websites to improve your site's search engine rankings and organic visibility, and it is the foundation of off-page SEO. Every link counts as a vote or reference from one page to another; links from authoritative, relevant sites raise your credibility. What matters is not the number of links but their quality.

## In short

In practice, link building is done through linkable content, digital PR, broken link outreach and coverage in industry publications. Links help search engines judge a page's authority and topic, so the anchor text and the relevance of the linking site both matter. Buying links or trading them in schemes breaks Google's spam policies and can lead to penalties. For example, a company that publishes original industry research can earn natural links from news sites and blogs that cite its data.

## Key points

- Google treats every link on the web as a 'vote' or reference from one page to another; the more quality references a site has, the more its value rises.
- A single link from a leading site in your industry is worth far more than links from hundreds of irrelevant, low-quality sites.
- Links are not just an authority signal: bots crawl the web by following links, which helps new content get discovered and indexed faster.
- A link on a relevant page that gets traffic also brings qualified referral traffic directly.
- The most sustainable method is earning links naturally through content marketing; comprehensive guides, original research, data-driven reports, infographics and free tools work like link magnets.
- Digital PR, guest blogging and getting listed on resource pages are other effective routes; buying links or dumping links on forums are outdated tactics considered spam.
- In broken link building you find a link returning a 404 on a relevant site, let the site owner know and suggest a similar, more up-to-date resource on your own site as a replacement.

Link building is the process of earning hyperlinks (that is, [backlinks](https://www.roicool.com/en/glossary/link-building)) from other websites to your own in order to improve your site's search engine rankings and organic visibility. It is the foundation of the search engine optimization (SEO) discipline known as off-page SEO.

In Google's eyes, the internet is a giant network of billions of interconnected pages. Every link in that network counts as a "vote" or "reference" from one page to another. A link from a respected, authoritative and relevant site raises your site's credibility and authority. The more quality references you have, the higher your value in Google's eyes.

But the key word here is **"quality"**. Google focuses on the quality of links far more than on their quantity. A single link from a leading site in your industry is worth much more than links from hundreds of irrelevant, low-quality sites.

## Why Is Link Building Still a Cornerstone of SEO?

Over the years many SEO tactics have changed and become obsolete, but the importance of link building has never faded. Here's why:

- An authority and trust signal: ever since the foundations of Google's PageRank algorithm, links have been one of the most fundamental metrics for measuring a site's authority. Quality links prove your site is an expert on its subject.
- Discoverability and crawling: search engine bots crawl the web by following links. When you get a link from a new site, it helps bots discover your site faster and [index](https://www.roicool.com/en/blog/what-is-index) your new content sooner.
- Referral traffic: link building isn't only about SEO. A user on the site hosting the link can click it and come straight to your site. If the link sits on a relevant, high-traffic page, it brings you a qualified, targeted audience.

## Modern, Effective Link Building Strategies

Leave aside the old tactics now considered spam (buying links, dumping links on forums and so on). Successful link building is built on creating value and building relationships.

### 1. Earning Links Naturally Through Content Marketing

This is the most powerful and most sustainable link building method. You produce content so valuable, informative or entertaining that other websites, writers and journalists naturally want to link to you.

- How to do it: create comprehensive guides, original research, data-driven reports, infographics or free tools. Content that solves a problem in your industry acts as a link magnet. This forms the foundation of a [digital marketing strategy](https://www.roicool.com/en/blog/digital-marketing-strategy-guide).

### 2. Digital PR

Digital PR is the process of earning backlinks from high-authority sites by creating an interesting story about your brand and pitching it to online news sites, industry publications and bloggers.

- How to do it: prepare a press release about a major achievement, a new product, compelling research or an expert opinion from your company, and get it to the right people.

### 3. Broken Link Building

This tactic involves finding links on other websites in your industry that no longer work (that return a 404 error).

- How to do it: you find a broken link on a relevant website. You email the site owner to point out the broken link. To be helpful, you suggest a similar, more up-to-date resource on your own site (a blog post, a guide and so on) that could replace it.

### 4. Guest Blogging

This means offering to write an article for a respected blog or online publication in your industry.

- How to do it: within the article you write, you link naturally to a relevant resource on your own site. This lets you reach a new audience and earn a quality backlink. What matters is offering genuinely valuable content, not just getting a link.

### 5. Resource Page Link Building

Many websites have pages such as "resources" or "useful links" that list the best resources they've found for their users.

- How to do it: find resource pages like these in your industry, reach out to the site owner and ask them to add your own comprehensive guide or tool, which you believe will add value to their list.

## Conclusion: Not Link Building, but Relationship Building

Link building is no longer a mechanical process. The key to success is to stop asking "How can I get more links?" and start asking "What can I create that is valuable enough for people and other sites to want to link to?"

Modern link building means creating outstanding content, building real relationships with others in your industry and laying your brand's reputation online brick by brick. Every link earned this way not only lifts your [SEO](https://www.roicool.com/en/services/seo-agency) rankings but also strengthens the foundation of your brand's long-term success and authority.
