What Are Backlinks? A Complete Guide to Getting Quality Backlinks

Backlinks are one of the oldest and most powerful concepts in SEO — and in 2026 they matter more than ever. They still help decide who ranks at the top of Google, and they now also influence whether AI answer engines like ChatGPT, Perplexity, Gemini and Google’s AI Overviews trust and cite your site. This guide explains what backlinks are, which ones actually count, and 12 proven, white-hat ways to earn them.

Backlinks, Explained

A backlink (also called an inbound link or incoming link) is simply a link from one website to another. When Site A links to Site B, Site B has earned a backlink from Site A. For example, if this article links out to Wikipedia, Wikipedia gains a backlink from SaveDelete.

The easiest way to think about backlinks is as votes of confidence. Every time a reputable site links to yours, it is effectively vouching for your content — telling search engines and readers, “this page is worth visiting.” The more relevant, trustworthy sites that vouch for you, the more authority your site accumulates.

The Role of Backlinks in SEO and AI Search

Backlinks matter for three big reasons in 2026:

• Search rankings. Links remain among Google’s strongest ranking signals. Pages with more high-quality backlinks tend to rank higher, because links help Google understand which pages are the most authoritative on a topic.
• Authority and trust (E-E-A-T). A healthy backlink profile from respected sites builds your site’s overall domain authority and reinforces Google’s Experience, Expertise, Authoritativeness and Trust signals.
• Referral traffic. A link on a popular, relevant page sends real visitors to your site — traffic that often converts better than search traffic because the reader already trusts the source.

The newest reason is AI visibility (sometimes called GEO, or generative engine optimization). Large language models and AI search tools decide who to cite partly based on how often — and alongside whom — your brand is mentioned and linked across the web. When your site appears in body copy, resource lists, podcast show notes and reputable roundups next to trusted names, AI systems start to treat you as a credible peer worth citing. In other words, the same links that help you rank in Google increasingly help you get named in AI answers too.

Types of Backlinks (and Which Ones Count)

Not all backlinks are equal. The two categories people talk about most are defined by a link’s rel attribute:

• Dofollow links pass “link equity” (often called link juice) from the linking page to yours, directly helping your rankings. A standard editorial link is dofollow by default.
• Nofollow links use rel="nofollow" and tell search engines not to pass full authority. Google now also uses rel="sponsored" (for paid/affiliate links) and rel="ugc" (for user-generated content like comments). Google treats these as hints rather than strict rules, so nofollow links can still carry some value.

It also helps to think about how a link was earned:

• Editorial links — given naturally because someone genuinely found your content useful. These are the gold standard.
• Manual / outreach links — earned by asking (guest posts, digital PR, resource-page requests). Legitimate and effective when done well.
• Self-created links — profiles, comments, directories and forum signatures. Mostly low value, and easy to overdo into spam territory.

Anatomy of a High-Quality Backlink

A single link from a respected, relevant site can be worth more than hundreds of weak ones. Here is what separates a great backlink from a worthless one:

12 Proven Ways to Get Backlinks in 2026

There is no shortcut to a strong backlink profile, but these white-hat tactics reliably earn quality links. Start with one or two, do them consistently, and compound the results over time.

1. Create genuinely link-worthy content

The foundation of all link building is content people want to reference: in-depth guides, clear tutorials, and pieces that solve a real problem better than anything else ranking. If your content is the best resource on its topic, links follow far more easily.

2. Publish original research and statistics

Data is link magnet. Surveys, studies, benchmarks and “state of” reports give writers and journalists something concrete to cite — and every time they cite your stat, you earn a link. Even a small original data set can attract links for years.

3. Build free tools and calculators

A genuinely useful free tool — a calculator, generator or checker — earns links naturally because people link to tools they recommend. SaveDelete’s own free online tools are a good example of link-worthy utilities.

4. Write guest posts for the right sites

Contributing high-quality articles to reputable, relevant blogs earns you a contextual link and puts your name in front of a new audience. Focus on relevance and genuine value, not just the link — low-effort guest posts on irrelevant sites can do more harm than good.

5. Use digital PR and source-request platforms

Journalists and bloggers constantly need expert quotes and data. Platforms like Featured, Qwoted and Connectively (formerly HARO) let you respond to reporter requests; a good answer can land you a link from a major publication. Pairing this with a newsworthy angle or data point is one of the highest-authority ways to earn links today.

6. Reclaim unlinked brand mentions

People often mention your brand, product or content without linking to it. Search for those mentions and politely ask the author to add a link — it’s one of the easiest wins in link building because they already know and referenced you.

7. Try broken-link building

Find broken (404) links on relevant pages, create or point to equivalent content on your site, and suggest your working link as the replacement. You help the site owner fix a dead link and earn a backlink in return. You can also reclaim links pointing to your own dead pages.

8. Get listed on resource pages

Many sites maintain curated “resources” or “useful links” pages in your niche. If your content genuinely fits, a short, personalized outreach email asking to be included is often all it takes to earn a relevant, editorial link.

9. Earn “best of” and roundup mentions

Getting your product, tool or content included in “best X” lists and expert roundups earns links from pages that already attract traffic and trust. Identify the roundups ranking for your topic and pitch why you belong on the list.

10. Guest on podcasts and get interviewed

Podcast appearances almost always come with a link in the show notes — and increasingly, those show notes and transcripts are exactly the kind of content AI engines read and cite. Interviews on other blogs work the same way, building both links and authority.

11. Replicate your competitors’ backlinks

Use a tool like an SEO backlink checker to see which sites link to your competitors. Many of those sites will link to you too — if they linked to a competitor’s guide, resource or tool, they may well link to your better version.

12. Refresh and re-promote old content

The “skyscraper” approach: find popular content in your niche, create something more current, more complete and more useful, then reach out to the sites linking to the outdated version. Updating and re-promoting your own aging posts also wins back lost links and keeps them relevant.

Link-Building Tactics to Avoid

Some shortcuts can get your site penalized or even deindexed by Google’s spam systems (Penguin, now part of SpamBrain). Steer clear of:

• Buying links or paying for dofollow placements without a rel="sponsored" tag — a direct violation of Google’s guidelines.
• Private blog networks (PBNs) and link farms built solely to manipulate rankings.
• Automated or bulk link schemes, spammy directory blasts and mass comment/forum links.
• Over-optimized anchor text — stuffing the same exact-match keyword into every link looks unnatural.

The risk almost never outweighs the reward. A handful of clean, relevant links will do far more for you than thousands of toxic ones.

Checking and Monitoring Your Backlink Profile

You can’t improve what you don’t measure. Keep an eye on your backlinks with:

• Google Search Console — free, and shows the sites and pages linking to you under the “Links” report.
• Ahrefs, Semrush or Moz — paid tools that reveal your full backlink profile, new and lost links, anchor text and competitor links. See our guide to the best AI SEO tools for options.

Review your profile at least quarterly. If you spot a pattern of genuinely toxic, spammy links you didn’t build, you can use Google’s Disavow tool — but use it sparingly, as most sites never need it.

Frequently Asked Questions

What is a backlink in simple terms?

A backlink is a link from another website to yours. If another site links to one of your pages, you have a backlink from that site. Search engines treat backlinks as votes of confidence, so links from trusted, relevant sites help your pages rank higher.

Do backlinks still matter for SEO in 2026?

Yes. Backlinks remain one of Google’s strongest ranking factors, and they now also influence AI search tools like ChatGPT, Perplexity and Google’s AI Overviews, which use links and mentions to decide who to trust and cite. The emphasis has shifted from sheer quantity to quality, relevance and context.

What’s the difference between dofollow and nofollow backlinks?

A dofollow link passes authority (“link juice”) to your site and directly helps rankings. A nofollow link uses rel="nofollow" and tells search engines not to pass full authority. Google treats nofollow as a hint rather than a strict rule, so nofollow links can still send traffic and add value — and a natural profile includes both.

How many backlinks do I need to rank?

There is no magic number — it depends entirely on your niche and how competitive the keyword is. A handful of high-quality, relevant links can outrank a competitor with hundreds of weak ones. Focus on earning quality links steadily rather than chasing a target count.

Are nofollow backlinks worth getting?

Yes. Nofollow links from popular sites drive referral traffic, build brand awareness and make your backlink profile look natural. Some of the most valuable mentions — from big publications, social platforms and Wikipedia — are nofollow, and they still contribute to visibility and trust.

Is it safe to buy backlinks?

No. Buying links to manipulate rankings violates Google’s guidelines and risks penalties or deindexing. If you pay for a placement, it should be marked with rel="sponsored" and treated as advertising, not SEO. Earning links through great content and outreach is safer and far more durable.

How long do backlinks take to affect rankings?

Usually a few weeks to a few months. Google has to crawl the linking page, register the link and reassess your page’s authority, and rankings tend to improve gradually rather than overnight. High-authority links from frequently-crawled sites often take effect faster.

Do backlinks help with AI search engines like ChatGPT and Google AI Overviews?

Increasingly, yes. AI answer engines decide who to cite partly based on how often your brand is mentioned and linked across trustworthy sources, and whether you appear alongside other credible names. Earning quality backlinks and mentions — in articles, resource lists, podcast notes and roundups — improves your chances of being cited in AI-generated answers.

The Bottom Line

Backlinks are still the backbone of SEO in 2026, and now do double duty by shaping your visibility in AI search too. The winning formula hasn’t really changed: publish content genuinely worth linking to, then use white-hat tactics like digital PR, broken-link building, guest posting and unlinked-mention reclamation to earn relevant, editorial links. Avoid the shortcuts, monitor your profile, and let quality links compound over time. For more, see our guides to building backlinks, domain authority and the best AI SEO tools.
