Quick answer: The main types of backlinks are editorial, guest post, directory, social, comment, and forum links – split further into dofollow and nofollow. Editorial links earned naturally from trusted, relevant sites carry the most ranking power, while spammy or paid links can hurt you. Quality and relevance matter far more than quantity.
What are backlinks and why do they matter?
A backlink is simply a link from one website to another. When a site links to you, it’s essentially vouching for your content – Google treats it as a vote of confidence.
The more high-quality sites that link to you, the more authoritative your site appears, and the higher you can rank. But here’s the catch: a single link from a respected industry site can be worth more than a hundred links from random, low-quality pages.
That’s why understanding the different types of backlinks matters. Chase the wrong ones and you waste time – or worse, get penalised.
It also helps to think of backlinks as part of a bigger picture. Google weighs them alongside your content quality, technical health, and user experience. Links amplify a strong site, but they can’t rescue a weak one. So while this guide focuses on links, treat them as one pillar of SEO rather than a magic shortcut.
What are the main types of backlinks?
Let’s break down the most common backlink types and how much ranking value each typically carries.
| Backlink type | What it is | SEO value |
|---|---|---|
| Editorial | Earned naturally when a site links to your content because it’s useful | Very high |
| Guest post | A link inside an article you write for another relevant site | High (if the site is quality) |
| Business / niche directory | Listings in reputable industry or local directories | Medium |
| Social media | Links shared on platforms like LinkedIn or Facebook | Low (mostly nofollow, but useful for visibility) |
| Forum & community | Links from genuine discussion contributions | Low to medium (high if spammy) |
| Comment | Links left in blog comments | Very low (often spammy) |
| Paid / link scheme | Links bought to manipulate rankings | Risky – can cause penalties |
Editorial backlinks
These are the gold standard. Another site links to you because your content genuinely deserves it. They’re hard to earn but carry the most weight – and they look completely natural to Google.
Guest post backlinks
You write a helpful article for a relevant site and include a link back to yours. Done well, on quality sites, these build authority. Done at scale on low-quality sites, they look like spam.
Directory backlinks
Listings in trustworthy directories – especially industry-specific or local ones – add legitimacy, particularly for local SEO. Avoid mass-submission to junk directories; those add no value.
Social and forum backlinks
Most are nofollow, so they don’t pass authority directly. But they drive traffic, boost visibility, and can lead to natural editorial links down the line. They’re worth it for reach, not for raw ranking power.
Dofollow vs nofollow: what’s the difference?
This is one of the most important distinctions in link building.
- Dofollow links pass authority (often called “link juice”) from the linking site to yours. These are the links that directly help your rankings.
- Nofollow links include a tag that tells Google not to pass authority. They don’t directly boost rankings, but they still drive traffic and keep your link profile looking natural.
Here’s the key insight on dofollow vs nofollow: a healthy backlink profile has a natural mix of both. If 100% of your links are dofollow, it looks unnatural to Google. Don’t obsess over only chasing dofollow – real websites earn both.
Which backlinks actually help you rank?
Beyond the type, three factors decide whether a link helps:
- Authority of the linking site. A link from a respected, established site is worth far more than one from an unknown page.
- Relevance. A link from a site in your industry signals real topical authority. An off-topic link means little.
- Placement and context. A link inside the main content, surrounded by relevant text, beats one buried in a footer or sidebar.
The takeaway: prioritise relevant, authoritative, editorially placed links. That’s where real ranking power lives. Building these is a core part of our SEO services, because they’re slow to earn but compound over time.
Which backlinks can hurt your rankings?
Not all links are good news. Some can trigger a Google penalty or quietly suppress your rankings:
- Paid links intended to manipulate rankings (against Google’s guidelines).
- Private blog networks (PBNs) – fake networks built just to pass links.
- Spammy comment and forum links dropped en masse.
- Links from irrelevant, low-quality, or foreign-language sites with no connection to yours.
- Exact-match anchor text overload – too many links using the same keyword looks manipulative.
If you’ve inherited a toxic profile, Google’s disavow tool can help – but prevention is far easier than cleanup.
What does a healthy backlink profile look like?
Google doesn’t just look at individual links – it looks at the overall pattern. A natural, healthy profile shares a few traits.
- A variety of link types. Real sites earn editorial links, directory listings, social mentions, and more – not just one kind.
- A mix of dofollow and nofollow. An all-dofollow profile looks engineered. Natural profiles have both.
- Diverse anchor text. Some links use your brand name, some use the page URL, some use descriptive phrases. Too many identical keyword-rich anchors look manipulative.
- Steady, gradual growth. Links earned over time look natural. A sudden spike of hundreds of links raises red flags.
- Relevant, authoritative sources. Most of your links should come from sites related to your industry.
If your profile checks these boxes, you’re building authority the safe way – the way that lasts through algorithm updates.
How do you check your backlinks?
You can’t improve what you can’t see. Before building new links, audit what you already have.
Google Search Console shows your links for free under the “Links” report – a solid starting point to see who links to you and which pages attract the most links. For deeper analysis, paid tools like Ahrefs, Semrush, or Moz reveal link quality, anchor text, and potentially toxic links.
When auditing, look for two things: opportunities (pages earning links you could replicate) and risks (spammy or irrelevant links you may need to disavow). A quick audit often reveals easy wins – like a high-authority site that mentions your brand without linking, which you can simply ask to fix.
Practical link building tips that work
Effective link building in 2026 is about earning links, not buying them. Try these:
- Create link-worthy content. Original guides, data, and tools naturally attract editorial links.
- Guest post on relevant, quality sites. Focus on audience fit, not just domain metrics.
- Get listed in trusted directories. Especially industry and local ones for local SEO.
- Build genuine relationships. Networking with others in your industry leads to natural mentions.
- Reclaim unlinked mentions. If a site names your brand without linking, politely ask for a link.
- Be patient. A steady trickle of quality links looks natural; sudden spikes raise flags.
Quality always beats quantity. Ten relevant, authoritative links will outperform a thousand junk links – and they won’t put your site at risk.
Common backlink mistakes to avoid
- Buying links in bulk. Cheap, fast, and dangerous – a common cause of penalties.
- Chasing quantity over quality. A high link count means nothing if the links are weak.
- Ignoring relevance. Links from unrelated sites add little and can look manipulative.
- Over-optimising anchor text. Vary your anchors so they look natural.
- Neglecting your own content. The best links are earned by content people want to reference.
Build links that last
The different types of backlinks aren’t equal – and chasing the wrong ones wastes effort or risks penalties. Focus on earning relevant, authoritative, editorial links through genuinely useful content and real relationships. That’s slower than shortcuts, but it builds an asset that keeps lifting your rankings for years. Safe, strategic link building is one of the pillars of our SEO services.

Backlinks remain one of Google’s strongest ranking signals – but the link-building advice online is full of myths. Some links lift your rankings; others can quietly drag your site down.

Frequently asked questions
What are the most valuable types of backlinks?
Editorial backlinks – earned naturally when a trusted, relevant site links to your content – carry the most value. High-quality guest post links come next. The common thread is authority and relevance: a link from a respected industry site beats dozens from random, low-quality pages.
What is the difference between dofollow and nofollow links?
Dofollow links pass authority from the linking site to yours and directly help rankings. Nofollow links include a tag telling Google not to pass authority, so they don’t boost rankings directly – but they still drive traffic and keep your link profile looking natural with a healthy mix.
Can backlinks hurt my SEO?
Yes. Paid links, private blog networks, spammy comment links, and links from irrelevant or low-quality sites can trigger Google penalties or suppress your rankings. If you’ve inherited toxic links, Google’s disavow tool can help, but earning clean links from the start is far safer.
How many backlinks do I need to rank?
There’s no magic number. Rankings depend on the quality and relevance of links, not the count. A handful of authoritative, on-topic links can outrank a competitor with hundreds of weak ones. Focus on earning quality links steadily rather than hitting an arbitrary target.
Are nofollow links worthless for SEO?
No. While nofollow links generally don’t pass ranking authority, they drive referral traffic, boost brand visibility, and keep your link profile natural. They can also lead to editorial dofollow links later when new audiences discover and reference your content. They’re valuable, just in a different way.
Should I buy backlinks to rank faster?
No. Buying links to manipulate rankings violates Google’s guidelines and is a common cause of penalties. The short-term gain rarely lasts and the risk is high. Invest instead in link-worthy content, guest posting on quality sites, and genuine relationships that earn links safely.
