SEO Reseller Programs: Complete Guide for Agencies in 2026

Backlinks are one of the most essential and powerful signals that Google uses to rank any website. There is a study to back this.

According to a Backlinko study, a webpage that ranks 1st on Google has an average of 3.8x more backlinks than webpages that pages that rank No.2 to No.10.

These backlinks serve as a trust signal, a recommendation, or, in essence, a vote of confidence.

It tells search engines,” your website is credible, valuable, and is worth checking out.” The more quality backlinks your website has, the more likely it is to rank higher in SERPs.

Simply put, backlinks are the main reason why some webpages get more traffic than others.

Undoubtedly, backlinks are important, but not all backlinks are good. Some backlinks help you rank higher, while some do nothing, and some backlinks can even hurt your website ranking in the long run. Therefore, it is essential to understand the types of backlinks and on which one you should focus – safe, grey-hat, or harmful. If you build backlinks without understanding it, you could waste your valuable time, money, and invite Google penalties.

In this blog, you will learn about the types of backlinks (safe, risky, and harmful). It will help you build the backlinks that help you rank higher in Google’s search results pages.

So, without further ado, let’s get started.

What are Backlinks?

Backlinks are links that your website gets from other websites. They are called backlinks because they “link back” to your site. Backlinks are also known as incoming or outbound links. It plays a major role in a website’s E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness), which is a key factor in how Google analyze content.

For example, if you run an online clothing store (Site B) and a popular fashion blog (Site A) links to one of your pages, that link becomes the backlink for your website. It not only brings more prospects to your store but also tells search engines that your website is credible and reputable.

Here, if website A links -> website B, it means website B has earned a backlink from Website A.

Backlinks help search engines understand that your website is useful or trustworthy. If trusted websites like Forbes.com are linking to your site, it means your content has value. That’s why Google treat them as a trust signal.

What Makes a Backlink Valuable?

A high-quality backlink will boost your ranking more than many low-quality backlinks. According to John Muller, the quantity of backlinks does not matter, but the quality of backlinks makes all the difference. He said this on Google SEO Office Hours.

Simply put, not all backlinks are equal; some can boost your website’s SEO while others may actually harm your rankings or reputation.

The following criteria define a high-quality backlink.

• Relevance of linking page – Your website should get backlinks from sites that are related to your topic or industry. If you run a lifestyle blog, a link from the credible clothing brand website is more useful than one from any random tech directory.

• Domain authority – A backlink from a website with strong authority, like Forbes.com or HubSpot.com, is more beneficial than a low-traffic website.
• Anchor text quality – Anchor text is the text that users click to visit the link. Backlinks with a relevant keyword or a clear description about the linked page’s topic help Google understand the context and relevancy of the link better.
• Placement in content – Where the backlink appears also matters. If the link is present in the middle of the blog post is more valuable than the one that is placed in a sidebar or footer. Context is also important. The backlink should be embedded naturally within the main content of the blog post. If it is placed in the sidebar, footer, or author bio, it is not that valuable. If the link is paid or placed out of context, it can harm your website’s rank.

• Link Diversity – Your backlink profile should include links from different websites and platforms instead of relying solely on a few dominant sources. It signals search engines that your website is relevant, trustworthy, and popular.

Types of Backlinks by HTML Attributes

If you want to grow your website, it is important to understand the different types of backlinks. Some types of backlinks pass authority while others are just for reference. Knowing types of backlinks helps you understand how Google sees your content and helps you build a stronger backlink profile. Before understanding its types, let us first understand what rel attributes are.

What are rel attributes?

The rel attribute, when applied to the <a> element it provides information to the search engine regarding the nature of the link, how they interpreted and passes ranking signals. Google also use these attributes for crawling and indexing purposes.

Here are four main types of backlinks.

1. Dofollow backlinks

They are the most valuable for SEO. These types of links pass authority (link juice) from the linking page to yours. If your website has more quality backlinks, your content will rank higher. All links are by default dofollow.

For example,

<a href = https://jeenaminfotech.com/> Trusted Link-Building Agency </a>

2. Nofollow backlinks

Nofollow backlinks tell search engines not to pass any authority to the linked page. Such links do not directly boost ranking, but they can still drive traffic and help you build brand visibility. These are useful when you don’t want to endorse any untrusted sites or affiliate links.

For example,

<a href = https://jeenaminfotech.com/ rel=”nofollow”> Read this </a>

3. Sponsored backlinks

Sponsored backlinks are also known as paid links. It indicates that the person inserting sponsored backlinks may get paid for doing it. Google considered them spammy. If you don’t tag sponsored links properly, it can be the reason for Google penalties or a drop in ranking.

For example,

<a href = https://jeenaminfotech.com/ rel=”sponsered”> Visit our website </a>

4. UGC backlinks

UGC backlinks usually come from user-generated content like forums, blog comments, or community discussions. It should be tagged properly to inform the search engine that the content was not published by the website owner.

<a href = https://jeenaminfotech.com/ rel=”ugc”> Read my blog </a>

 UGC links don’t pass much authority, but they can be useful for driving referral traffic or brand discovery when used naturally. 

Types of Backlinks (Based on How They’re Built and Where They Come From)

Not all backlinks are useful. Some can boost traffic significantly, while others can harm your website, and others do nothing. Here we have grouped them into three different categories – the good, the neutral, and the bad.

A. Safe Backlinks (White-Hat)

Backlinks that follow Google’s guidelines and are genuinely earned are safe backlinks. They help you boost your website’s authority over time and positively impact your SEO performance.

1. Guest Posts on Relevant Blogs

Guest post backlinks, you generally get by writing blogs or articles for other websites in your industry. You can provide valuable content to their audience, and in return, you get one or two links back to your own site. It helps you reach a new audience and build authority in your niche. 

For instance, if you are a digital marketing agency and create a blog post on digital marketing, linking it to your landing page, it’s considered a guest post link. Usually, guest post backlinks appear in the author bio or naturally within the post. To maximize your benefits, always choose websites with good authority and real traffic. Your guest post content should be clear, concise, useful, and not overly promotional.

2. Editorial Links from Content

Whenever other websites find your content useful and valuable, they naturally add links to your website. You don’t ask them to do it, but they do it because your content genuinely offers something valuable, which is worth referencing. These are the best backlinks that you can get.

Usually, editorial backlinks come from blogs, news sites, or other industry resources. If you publish original research or unique insights that others want to cite, you can increase your chance of earning editorial links.

3. Contextual Links Within Body Copy

Contextual links are placed into existing content on another website. In this, you don’t write new content, but you reach out and request that they add your link to their webpage. It is also known as link insertions.

For example, if there is a good blog post on link building and your tool fits into that topic, you can ask the author to add your link. It will help you quickly get relevant links from the aged content.

Such link efforts take time, but they bring serious SEO value. You don’t need to be an expert to start; all you need to offer is value and be consistent in that.
