What are Backlinks in SEO?

In terms of Google SEO, websites with 100+ backlinks rank 3x higher compared to those that have fewer than 10 links. This piece of information comes from Ahrefs and serves as a good piece of data to confirm the suitable creativity of backlinks in SEO. But what is the actual definition of backlinks and why do they rise above your website’s search engine rankings?

To put it simply, backlinks are the links from one webpage to another. These herein called “votes of confidence” by Google prove the page’s authenticity and quality. When a well-known website links to your page, Google considers it to be a sign of quality, authority, and value, thus it is displayed at the top of search results.

However, it is not a universal truth that every backlink has the same influence on the position of the page. A single link from a highly regarded site such as The New York Times can shoot up the rankings by over 100 links from low-quality, spammy domains. This is why you have to know what a “good” backlink is and what are the ways of creating them in the right way.

Why Backlinks Matter More Than Ever

Google’s algorithms never stand still, and the March 2024 Core Update further increased the link quality and relevance criteria. Gone are the days when only the number of links was of the utmost importance. Nowadays, Google highly regards authoritative quality, relevance, and trustworthiness—attributes that are directly influenced by your backlink profile.

For example, if you are a fitness blog owner, a backlink from Men’s Health, a famous health magazine, will be way more valuable than if you got a random link from a blog about car repairs. This is because Google thinks that topical relevance and linking domain authority are the main determining factors.

So if you’re ready to harness the full power of backlinks and to elevate your SEO game, then just stay with me and I will provide you with the ‘know-how,’ the tools, and the strategies necessary to make it happen.

The Science of Backlinks 

Backlinks are the core of search engine optimization (SEO), and to use them effectively, you should know the underlying facts of what they do. In this chapter, we’ll explain how search engines use backlinks, the different types of backlinks, and how to find and get rid of bad links that are bad for your rankings.

1. How Search Engines Use Backlinks

Google’s PageRank Algorithm

At the basis of Google’s grading scheme is the PageRank algorithm, which was named after the co-founder of Google, Larry Page. PageRank operates on the premise of evaluating the quantity and quality of backlinks that link back to a webpage. Here is a simple explanation of how it works:

• Every single backlink is like a “vote” for your page.
• All the votes are not equally important. For example, the links that come from highly-rated Ph.D. students and medical professionals are heavier and thus more beneficial than the links from low-rated YouTube or irrelevant websites.
• Google has a complex formula that decides which page will be on top of the search. It is called a “page score” that is produced by this formula that calculates the search ranking of the page accordingly.

Visual Explanation: Think of a popularity contest, and every vote is checked by the reputation of the person who gives it a try. A vote from a top site (high-authority site) is given a higher score than the one from an unknown site (low-authority site).

Authority Transfer: Domain Authority (DA) vs. Page Authority (PA)

When a party wins you to their website, they then take a part of their authority to yours. This authority is calculated with metrics like:

• Domain Authority (DA): A score (0-100) predicting the website’s performance of matching the search engine’s measurements.
• Page Authority (PA): The possibility for a respective page to be ranked can be predicted with the help of the score (0-100).

Case Study: From #15 to #1 with 10 Editorial Backlinks

An e-commerce site that specializes in eco-friendly products found itself at a standstill at position #15 for its target keyword, “sustainable water bottles.” The website’s ranking surged to #1 two months after obtaining 10 editorial backlinks from high-authority blogs in the sustainability sector. 

Key Takeaways:

• Quality is more important than quantity.
• Editorial links (earned naturally) are the most powerful.

2. Types of Backlinks

Every backlink is different. Being familiar with the different kinds will help you to create a diverse and efficient backlink profile.

1. Editorial Links (Earned Naturally)

These are the gold standard of backlinks. Editorial backlinks denote that another website is talking about your web page because it is valuable, informative, or newsworthy.

Example: A blogger creates a post with the title “Top 10 Eco-Friendly Products” and then links to your sustainable water bottle page.

2. Manual Links (Guest Posts, Outreach)

Well, such links come to your directory through an enthusiast when he uses your anchor text on a different website of his or hers. This can happen through conversation or as a part of the content of another web page.

• Guest Posts: Write articles for other blogs in your niche and include a link back to your site.
• Outreach: Pitch your content to influencers or bloggers and ask for a link.

Pro Tip: Concentrate on domains with high authority and relevance to your niche.

3. Self-Created Links (Forums, Silos – Use with Care)

These are the links that you add such as forum signatures, directory submissions, or blog comments. However, not all that simple is good; they can be dangerous if used heavily, as they do not bring much SEO value or even damage the site.

To get the best results, use self-made links only a few times and only on well-established websites.

Anchor Text Breakdown

Anchor text, underlined text with links to another part of a website, is an important element in search engine optimization. It lets search engines know about the content your linked page is providing.

• Branded: This is the type of anchor text that is related to and contains your brand name (e.g., “EcoBottle”).
• Generic: This anchor text does not provide any particular information and instead includes generic phrases such as “click here” or “learn more.”
• Exact-Match: Anchor text of this type is written around the target keyword to increase the webpage’s SEO score.

Recommended Ratio:

• 50% Branded
• 30% Generic
• 20% Exact-Match

Overuse of exact-match links might result in duplicate content and penalties from Google. Hence, you should strive to achieve natural distribution when building links.

4. Toxic Backlinks: How to Spot and Disavow Them

Wrong links can do more harm than good. Instead of improving your site’s position, some of them may cause your website to be penalized and banned. This is how you can find them and effectively manage them with coping strategies.

Red Flags of Toxic Backlinks

• Spammy Domains: Links having low domain authority, inappropriate content, and spam records are the ones to be avoided.
• Irrelevant Links: Links of this category are basically not in any way related to your area of coverage, say, a gambling site and your eco blogs.
• Over-Optimized Anchors: Over-optimizing your anchor text to the extent of continually repetitive use of the exact-match anchor text is no good for your link anchor texts

Tools to Identify Toxic Backlinks

• SEMrush Backlink Audit: This tool will highlight risky backlinks that are damaging your site’s SEO ranking and display them back to you.
• Google Disavow Tool: This is the link disavow tool from Google where you can suggest to it sites that you do not want to be linked with.

Case Study: Recovering from a Penalty

One of the travel-related blogs that I came across recently is the one that went from a high-ranking site to an inexplicable low-ranking site just because they managed to acquire a total of 500+ spammy links within a period of a few weeks. However, with the help of SEMrush, the site owner was able to detect the penalizing links and thereafter he transmitted a disavowal file through the Disavow Tool. After a short period, all the rankings were back again.

Steps to Disavow Toxic Links:

1. Use a service like SEMrush or Ahrefs to export your backlink profiles.
2. Recognition of harmful links with the red flags that were given above.
3. Develop a disavow file, which is a plain text file containing URLs or domains you need to disavow.
4. Send your disavow file to the Google Disavow Tool.

Pro Tip: Regular monitoring of your backlinks will help you detect toxic links at an earlier stage.

Backlinks 101: Trust, Authority, and Optimization

Backlinks are an important factor in rankings and are responsible for giving trust and authority signals to search engines.

You would focus on earning links with editorial knowledge and creating manual links to outreach and guest posting.

Rid yourself of the toxic backlinks that follow up by regular audits of your backlink profile and use the likes of SEMrush and Google’s Disavow Tool.

In the science of backlinks, you get to become an expert in building a stronger, healthier backlink profile that moves up the rankings and drives traffic. 

How to Build High-Quality Backlinks 

Link building is one essential component of a successful SEO strategy. In this chapter, we will review content marketing, outreach, and partnership ways that are proven to increase your authority. We will also address unethical techniques that can damage relying on being quick and easy.

1. Content-Driven Strategies

Skyscraper Technique 2.0

The Skyscraper Technique, which was coined by Brian Dean of Backlinko, concentrates on the production of the best possible content for the particular topic to be ranked for. Here’s how it’s done:

1. Pick the Best Content: The quickest way to uncover the best page ranking for your keyword is to utilize tools such as Ahrefs or SEMrush.
2. Make it Even Better: Present an additional section or include some recent information or visuals.
3. The Offer to Backlink Sources: Give the backlink sources to the page of the updated content and ask them to redirect the link to your originated content.

Original Research

One of the most important methods of getting quality backlinks to come to your site is writing and publishing original research. Besides the page views and citation reports from the homepage, such issues can be easily shared and cited by other sites, e.g., .com. or .org.

For instance, a digital marketing company issues a survey on the topic titled “2024 Survey of 1,000 Marketers” and through it, it manages to get backlinks from .edu and .gov legit domains.

Steps to Create Original Research:

1. Firstly, focus on choosing a topic that is in your direction or niche.
2. Start with assessing the data, which was conducted through surveys, experiments, or in the case of industry reports.
3. Another way of presenting the information is by providing thorough details in the format of an interactive chart or a PDF.

Visual Assets

Data in the form of graphics helps to teach people about subjects and can be more readily used in blog posts, media, and for sending information wirelessly from one mobile device to another.

For example, a corporate wellness platform publishes a “Calorie Burn Calculator” wherein people get linked to over 50 different health and wellness sites.

Tips for Creating Visual Assets:

Canva and Piktochart make infographics very compelling and easy to create.

Let your domain URL be explicit in the content too.

Along with this, there are next things you have to consider which are the outreach and social media that you will use for the promotion of it.

HARO (Help a Reporter Out)

HARO is a platform that makes the contact of journalists and experts easy, for quotes, and insights. Besides, high-authority news sites can offer you backlinks if you position yourself as an expert.

How to Use HARO:

1. the first is to help sign up at HelpAReporter.com.
2. consider providing helpful responses to questions that concern a particular topic.
3. Make sure the backlink leads to your site when you get the answer.

Example: A nutritionist responds to a query about “Healthy Eating Trends” and earns a backlink from Healthline.

2. Partnerships and Collaborations

Co-Marketing Campaigns

Work together with influencers or related brands to form content which are of mutual benefit.

Example: A SaaS company collaborates with a marketing influencer for a webinar on “SEO Trends 2024.” They both promote the webinar, gaining incoming links from the participants and industry blogs.

Guest Post Swaps

Just collaborate with other sites that are in different niches and are not your direct competitors to negotiate a guest post swap. With this, you gain access to other audiences and get backlinks as well.

Example: A travel blogger pens a guest post for a photography blog this way, linking back to the respective websites.

3. Avoiding Black-Hat Tactics

Risks of PBNs (Private Blog Networks)

PBNs are connected groups of websites that are built mainly for the purpose of providing links. Although they can immediately bring about outcomes, they are against the policies set by Google, thus, penalties are likely to happen.

Example: A website implementing PBN to enhance rankings was penalized; the site lost 80% of its organic traffic overnight.

Link Exchanges and Automated Tools

An overabundance of exchange of links and automation in building links can also cause sanctions. Focus on earning links organically by producing excellent content and reaching out to others.

Metrics to Prioritize

• Domain Rating (DR): A score (0-100) that estimates the ability of a domain to rank.
• Referral Traffic Potential: Is the linking site where visitors are coming from?

The “Trifecta” Test

A high-quality backlink should be:

• Trusted: A reputable, authoritative source, should it be.
• Relevant: Relating to your niche or topic, it should be.
• Authoritative: The site has a high DR or PA, right?

3. Link Building for E-A-T

In the Google algorithm, E-A-T (Expertise, Authoritativeness, and Trustworthiness) is the most essential criterion. E-A-T can be greatly enhanced by the links you get from educational or governmental sites.

Example: A health blog gains a high-quality link from a .edu domain increasing its authority and rankings.

Future of Backlinks and SEO 

The world of SEO is always on the move, and backlinks are still the most important factor in these terms. In this chapter, we’ll explore how AI, Google’s algorithm updates, and emerging trends are shaping the future of backlinks and SEO.

Impact of AI on Link Building

AI-Generated Content vs. Human Outreach

AI tools like ChatGPT are undoubtedly a game-changer in terms of generation of content, but they are not able to replace the human touch in link building.

• AI-Generated Content: Useful for creating drafts or brainstorming ideas, but lacks the nuance and creativity of human-written content.
• Human Outreach: Essential for building relationships and earning high-quality backlinks.

Example: On the one hand, an AI-generated guest post might get published, but on the other hand, a personalized outreach email will be more likely to secure a backlink from a top-tier site.

Google’s Evolving Focus on Topical Authority

Google is in the process of replacing domain authority with a different system called topical authority. This trend can be seen to denote that informational websites that can show authority in some topics will fare better than their peers, even though the overall power of domains is lower.

How to Adapt:

• Create in-depth, niche-specific content.
• Earn backlinks from sites within your niche.
• Focus on E-A-T (Expertise, Authoritativeness, Trustworthiness).

Example: A blog about “Vegan Recipes” earns backlinks from vegan influencers and nutritionists, boosting its topical authority.

Predictions for 2025

1. Voice Search Optimization

The more voice search expands, the more voice-friendly site backlinks (like FAQs, and how-to guides) will become in demand.

Actionable Tip: Make your content voice search-friendly by including conversational keywords and getting linkbacks from voice search directories.

2. Entity-Based SEO

Google is becoming an entity-based search engine that catches on to concepts instead of just words by doing so.

Actionable Tip: Get massive amounts of brand-building backlinks from the sites that are your entities’ extensions (like Wikipedia and your industry directories).

3. Video Backlinks

As video content began to take over, the value of backlinks to YouTube and TikTok became ever greater.

Actionable Tip: Prepare video content and embed it in your site so that you can attract video backlinks.

Keywords Integration

By addressing the primary questions while creating the guide we’ve managed to highlight our main focus online, what they are, and how they function:

1. What are Backlinks in SEO? Backlinks refer to hyperlinks that are linked from one website to another, that are acting as “votes of confidence” helping to increase rankings.
2. What’s Domain Authority? It’s the evaluation scale that shows how well a site will perform in the search engine results which are based on its link profile (the stronger the more the site carries the weight of the link with the higher authority).
3. The Positives of Backlinks: The most important ones are the improved search position, attracted visits, and recognized authority.
4. How to Get Backlinks: The most common ways are using techniques like the Skyscraper Technique, outreach, and partnerships, which are the most efficient methods.
5. SEO Backlinks Strategy: The Golden Rule here is that you should never sacrifice the first two qualities for a higher quantity. Quality content is always king!–for this reason, the principal considerations should be whether the information is worth crafting and whether am I qualified to express it.
6. Dofollow vs. Nofollow Backlinks: Dofollow links denote that the search engines are allowed to monitor, index, and pass a part of the PageRank flow to the linking pages, while nofollow links are those that signal to the search engines not to follow them, although they are still good for driving visitation.
