Link Building in SEO: understand everything!

In the constantly evolving world of SEO, link building is a central pillar that continues to influence the way websites are ranked on search engines.

But what exactly is link building? This involves the creation and acquisition of inbound links, commonly called “backlinks”, which point to a website.

These links are interpreted by search engines as votes of confidence, highlighting the relevance and authority of a site. In this article, we’ll explore in depth the importance of link building, how it has evolved over the years, and best practices for effectively integrating this strategy into your SEO efforts.

SEO is based on three fundamental criteria, namely content , technique and popularity . It is on this last point that link building comes into play. “Link building” thus makes it possible to generate more traffic by optimizing the popularity of the page .

Why is link building important and what is its role in SEO then?

The origins of link building date back to the beginnings of the internet. How did this practice evolve to become what it is today?

The Beginnings of SEO and the Role of Links: When search engines first emerged, their primary goal was to index and provide relevant information to users. Links, at that time, were mainly used as references or recommendations from one site to another. Google, from its beginnings, used the PageRank method to evaluate the popularity and relevance of web pages based mainly on links. A site with many links pointing to it was considered a reliable and relevant source, and therefore ranked higher.

Major algorithm changes and impact on link building: Over time, as with any system, malicious actors have tried to manipulate results by creating networks of artificial links. To combat these “black hat” techniques, Google introduced several algorithm updates, the most notable being Penguin in 2012. This update specifically targeted sites that used unnatural or manipulative linking techniques, thus penalizing many sites.

This shift redefined how digital marketers viewed and used linking. It became clear that the quality of links far outweighed their quantity. Additionally, the relevance and authority of the source site have become key elements in assessing the value of a backlink.

Thus, through these developments, link building has transformed: from a game of numbers, it has moved to a strategy focused on quality, relevance and real value for users. Combined with an “internal linking” strategy, we can obtain interesting results thanks to external and internal links.

What is its role then?

In the vast range of SEO techniques, link building occupies a crucial place. But why does a simple link have such an impact on SEO? Here are some reasons that highlight its importance:

1. Links as votes of confidence: Google and other search engines interpret backlinks as votes of confidence or recommendations. When one site links to another, it suggests that it finds the latter’s content relevant and worth sharing. Thus, a site with a significant number of quality inbound links is perceived as having great added value for users. Even better if this link provides added value to the information and meets the search intent.

2. Relevance and authority indicators: Links are not just votes; they also provide clues about the relevance of the content. If a nutrition blog post receives links from recognized medical organizations, it is likely that the content is knowledgeable and relevant. Additionally, search engines use these links to understand what the linked site is about and improve its ranking in relevant search results.

3. Distribution of “Link Juice”: When a site links to another page, part of its authority (often called “link juice”) is passed to that page. This means that inbound links can increase the authority of a page and, therefore, improve its search engine ranking.

4. Discovery of new pages: Search engines use robots to explore the web. During this crawl, they follow links from one page to another, which allows them to discover new pages and index them. So, having inbound links from already indexed sites can help a new page be discovered faster by search engines.

5. Direct Traffic: Apart from the SEO aspect, backlinks also generate direct traffic. When a visitor clicks on a link on an external site, they are taken directly to your site, increasing the number of visitors.

In conclusion, link building is not just about getting a large number of links. It’s a complex strategy that, when executed well, can boost a website’s relevance, authority, and visibility in search results.

A quality backlink: the basis of link building

Today, particularly with the appearance of Google Penguin , quality is premium and massive link creation is penalized. By bringing together all these conditions, we can say that a quality backlink is the main ingredient of an SEO strategy.

Here are some criteria that a quality backlink should meet:

  • Place yourself in content with the same semantic field as the targeted page,
  • Position yourself on popular pages,
  • Have a simple and precise description on the anchor text, (For example if you offer SEO services for health sites you must put a link on the text which describes your activity)
  • Diversify the sources of incoming links on your website,
  • Prioritize older websites,
  • Properly position the links in the editorial content of the page,
  • Opt for links from sectors with significant traffic.

In the incessant quest for better rankings, a fundamental question often arises for SEO specialists: should we prioritize the quality or quantity of backlinks? Let’s dissect this question and highlight the importance of quality in link building.

1. The initial vision of search engines: In the beginning, search engines, particularly Google, evaluated the popularity of a site mainly on the quantity of its inbound links. This has led to a frantic race to acquire as many backlinks as possible, sometimes without regard for their relevance or quality.

2. The evolution towards quality: Faced with manipulation techniques and the proliferation of low-quality links, search engines have refined their algorithms. They started giving more weight to link quality. Today, a single backlink from an authoritative and relevant source can have a much more significant impact than a multitude of low-quality links.

3. How to identify a quality link? – Domain Authority (DA) and Page Authority (PA): These two metrics, developed by Moz, respectively evaluate the overall authority of a domain and that of a specific page. A link from a site with a high DA is generally more valuable. – Relevance of the source site: A link from a site with a similar theme or subject to yours is considered more relevant. – Source Site Traffic: A link from a site with high and active traffic can not only improve SEO, but also drive direct traffic to your site. – Link position: A backlink located in the main content of a page generally has more weight than a link at the footer or in a sidebar.

4. Risks associated with prioritizing quantity: – Search engine penalties: Search engines may penalize sites that attempt to manipulate their rankings by artificially acquiring a large number of low-quality links. – Toxic links: Links from suspicious or penalized sites can harm a site’s reputation and ranking.

The lesson to be learned is clear: in the world of link building, quality takes precedence over quantity. Focusing on obtaining relevant, high-quality backlinks is essential to ensure a successful and sustainable linking strategy.
