Link Juice and Dumping Factory : What is it and why is it important for SEO?

The concept of “link juice” is fundamental to understand how links affect the authority and positioning of a web page in search engines. In this article we will explore what link juice is, how it is distributed and why it is so important to improve a site’s visibility in google and other search engines.

What is link juice?

Link juice, also known as “link juice”, is a term used in the SEO world to describe the value or authority that a link conveys from one web page to another. When one site links to another, some of its authority is transferred to the linked site, increasing its relevance and potentially improving its position in search results.

Link juice can come from both internal and external links. External links are those that come from other domains, while internal links are those that connect pages within the same site. Both types of links are important, as they help distribute value in a way that favors the structure and hierarchy of the content.

How link juice works?

To understand how link juice works, it is useful to think of a page’s authority as a resource that can be shared with others. When a page with a high authority links to another page, it is sharing some of that authority, which can contribute to improving the ranking of the linked page. Google and other search engines consider these links as “votes” of confidence that indicate the relevance and quality of the content.

However, not all links are of equal value. Factors such as the quality of the source site, the number of links on the page and the relevance of the linked content play a crucial role in the amount of link juice that is transferred. A link from a high authority page with related content will have much more value than a link from an unreliable or irrelevant site.

Dumping factor in seo

The “dumping factor” in SEO refers to the probability that a user arriving at a web page loses interest and leaves the page, either by navigating to another site or by closing the browser. This factor is expressed with a value between 0 and 1, where a higher value indicates a higher probability of abandonment.

In SEO, the dumping factor is related to pagerank and link juice, or the internal strength of a URL, which depends on its location in the website structure and the ease with which Google bot can access it. Each time Google bot accesses a new page, it follows the available links, and the authority of each URL decreases as the depth of navigation increases.

According to the dumping factor theory, each link passes on approximately 85% of the authority of the source page, which means that the strength of the authority decreases with each level of depth. Although the value tends to decrease, it never reaches zero; in terms of pagerank it is estimated to be equal to 1-d, where d = 0.15.

How is the dumping factor calculated?
To illustrate the calculation of the dumping factor, let’s consider a typical example of an e-commerce site:

• A: This is the main page (homepage) of an online store. This is the source URL and is at level 0 depth.
• B: This is the category page, which is accessed from the main menu of the homepage. It is located at level 1 depth.
• C: This is the product page, accessed via a link on the category page. It is at depth level 2 (requires two clicks from the home page).

To calculate the dumping factor and the authority lost on each link, we would do the following calculations:

• A (pagerank = 1) → B (pagerank = 1 * 0.85) → C (pagerank = (1 * 0.85) * 0.85)
• That is:
  • A: It keeps all its internal strength and its PageRank is 1.
  • B: It needs one link to reach it, so it keeps 85% of the internal strength, i.e. 0.85.
  • C: It needs two links to reach it, so its strength is 0.85 * 0.85, i.e. 0.7225.

Factors affecting link juice

There are several factors that determine how link juice is distributed between pages:

1. Authority of the origin site: Links from sites with high authority, such as those with a good domain (trust flow and domain authority), transmit more value. A link from a site such as a university or a major news portal will have a greater impact than a link from a blog with no reputation.
2. Content relevance: Links that come from pages with content related to your site convey more value. Google interprets these links as more relevant, which increases the credibility of your content.
3. Number of links on the source page: If a page has many outbound links, the amount of link juice transmitted to each one is diluted. Therefore, links from pages that contain only one or two links may have more value than those from overlinked pages.
4. “NoFollow” attribute: Links with the “nofollow” attribute do not transmit link juice. This attribute is used when you do not want a link to pass authority, such as in the case of sponsored links or links in comments.

Strategies to make the most of link juice

To take advantage of link juice effectively and improve the SEO of a website, it is important to follow some key strategies:

1. Optimize Internal Links: Use internal links to guide link juice to the pages you want to improve rankings. Be sure to link to the most relevant pages and those you want to highlight.
2. Get Quality Links: Work on getting quality links from sites with high authority and related content. Strategies such as creating valuable content that others want to share, guest posting and networking with other sites can help.
3. Avoid Excessive Linking: Don’t overload your pages with outbound links, as link juice will be divided among all of them. Concentrate on keeping relevant and quality links to maximize their value.
4. Adequate Redirects: If a page is removed or moved, make sure to use 301 redirects to keep the link juice that may be associated with those links. This is crucial to maintain the site’s authority.

Importance of link juice for SEO

Link juice is important because it is a key way in which search engines determine the relevance and authority of a page. By having a good link building strategy and optimizing the distribution of link juice within your site, you can increase the chances of your important pages ranking higher.

Quality external links act as votes of confidence that support your content, while internal links help distribute that value within your site and guide both users and search engines to the most relevant pages.

Conclusion

Link juice is an essential concept for any effective SEO strategy. Understanding how authority is transmitted between pages and applying strategies to maximize link value can help to significantly improve a site’s visibility in search results. Link smart, get quality links and optimize your internal structure to make the most of link juice.
