What is a Backlink?

A backlink is simply a link from another website to your own. Search engines use backlinks as a factor to determine the ranking of websites on their search results pages (SERP).

In short, the more high-quality backlinks pointing to your site, the better your chances are of ranking well in the SERP.

How Does a Backlink Appear in Source Code?

When one site links to another, it uses a link tag in its HTML code.

This link tag includes the URL of the page the link points to, along with additional information like the anchor text (the text that appears on the linked page) and/or the title attribute (extra text that describes the link).

Here's an example of a backlink pointing to my site from a website mentionning SerpSEO:

<a href="https://www.serpseo.io/"> <b>stat now with a ctr bot<b> </a>

Breakdown:

  • <a>: link tag
  • href=: link attribute

Why Are Backlinks Important in SEO?

A backlink is a link that points from one website to another. If someone links to your website, you earn a backlink!

Backlinks are crucial for SEO because they help search engines understand the popularity and authority of a website.

With a good link-building campaign, your website's ranking can improve. This is why there are platforms for buying backlinks and agencies specializing in link building.

How Does Google Highlight Sites in Its Index?

Google uses several factors to assess the quality of a site and its ranking.

First, the quality of the content is taken into account by the algorithm. Second, there's the aspect of link building.

What is "PageRank"?

PageRank is the algorithm used by Google to rank websites in its search engine results pages. It's named after Larry Page, one of Google's co-founders.

The PageRank algorithm considers the number and quality of links to a website to determine its ranking. As mentioned earlier, the more and higher quality the links, the higher the page score and its potential ranking.

Which Links Have the Least Value to Google?

Understanding SEO Authority:

The authority of a backlink is directly linked to the PageRank of the linking page. A higher PageRank means the link comes from a more authoritative source and therefore has more value.

Natural vs. Artificial Backlinks:

Natural backlinks are earned organically through the content you produce, while artificial backlinks are intentionally generated through various methods.

In SEO, there's much debate about the value of natural vs. artificial backlinks. Many believe natural backlinks are more valuable, while others disagree. However, no studies have proven that artificial backlinks are less effective.

What is a "nofollow" Link?

A "nofollow" link includes the attribute rel="nofollow". This tells Google not to consider these links in its algorithm.

While Google says it uses nofollow links for contextual purposes and to understand the destination pages better, they are not supposed to be a bonus for the receiving sites.

Criteria for Acquiring Backlinks

The Link Profile of the Referring Domain:

When acquiring backlinks from quality websites, it's crucial to focus on the link profile of the referring domains.

A quality link profile means the domain has high authority and will pass on strong SEO juice.

SEO Traffic and Domain Positions:

When seeking backlinks, it's also important to focus on domains that receive a lot of search engine traffic.

If a site ranks well on Google and attracts organic traffic, it means the search engine deems it relevant, returning to the fundamental notion of domain authority.

Link Placement on the Site:

A backlink in the footer of a website is not as valuable as a link in the middle of themed content. Google considers the quantity of links, but their context also plays a role in thematic PageRank.

Thus, it’s better to position your links within themed paragraphs, aligned with the topic of your destination page.

Popular Techniques for Obtaining Backlinks:

Technique | Description | Effectiveness

Ninjalinking:Acquiring backlinks from directories, comments, or petitions. These formats often allow users to easily insert their links. However, these links often have nofollow or ugc attributes, making them less effective for Google ranking.

Link Exchange:Exchanging links with another website. This method is often used by webmasters to quickly acquire backlinks. But beware! If Google detects this, your site could suffer.

Linking with Partners:If thematically aligned with your site, your partners' websites can link to yours. You can reciprocate by adding a link to their site in your footer or content.

Guest Blogging:Writing articles on other blogs to acquire backlinks. This method is very effective, provided the links are placed in themed articles, not just in the author bio.

Buying Links:You can buy links from other sites, but this is strongly discouraged by Google. However, if done correctly, this technique allows total control over your link profile.

Key Takeaways:

To acquire quality backlinks that will improve your SEO, regardless of the technique used, it's important to consider the link profile of referring domains and focus on websites that receive substantial search engine traffic.

Best Tools for Link Building:

Difference Between Link Building and Internal Linking:

Internal linking involves connecting one page of your website to another. This offers several benefits:

  • It helps search engines understand the structure of your site and find new pages more easily.
  • It allows you to distribute "link juice" (internal PageRank) across your site.
  • It helps keep visitors on your site longer.

To do this, simply insert links in your content to other pages on your site or in your navigation menu. And as with link building, always consider the semantic proximity between pages!
