Guide to Understanding the Different Types of Backlinks
Quick answer: Backlinks are links from other websites pointing to yours, acting as a signal to search engines that your content is credible and worth ranking. Not all backlinks are equal — editorial links from reputable, relevant sites carry the most value, while manipulative tactics (buying links, link schemes, excessive reciprocal linking) can violate Google’s spam policies and hurt rather than help your rankings. This guide covers the main backlink types, which are safe to actively pursue, and which carry real risk.
Key Takeaways
- One genuinely high-quality backlink from a reputable, relevant site outweighs many low-quality ones.
- Editorial backlinks — earned because your content is genuinely useful — are the most valuable and lowest-risk type.
- Manipulative link-building tactics (paying for links, badge-for-link schemes with no editorial merit, spammy comment links) can violate Google’s spam policies.
- A natural, diverse anchor text profile looks far more organic to search engines than heavily repeated exact-match phrases.
Search engines evaluate your website partly by the company it keeps — the sites linking to you. Google’s systems look for links connecting to genuinely high-quality, relevant content as one signal among many for how a page should rank. Here’s how the main types of backlinks work, and how to build them without running into trouble.
What Backlinks Actually Do
A backlink (or inbound link) is a clickable link from another website to yours. When multiple relevant, reputable sites link to your content, it signals to search engines that your page is worth reading and citing — contributing (alongside many other factors) to how your site ranks.
- Backlinks are also called inbound links.
- They’re clickable — users can navigate from one site to another through them.
- Quality matters far more than quantity — one link from a genuinely authoritative, relevant site typically outweighs dozens from low-quality ones.
The Main Types of Backlinks
1. Editorial Backlinks
An editorial backlink is a link another site includes naturally, within its own content, because your page genuinely adds value. This is the highest-value, lowest-risk type of backlink because it’s earned rather than requested or paid for. Common triggers include:
- Another site cites your article, data, or infographic as a source
- A publication quotes someone from your business
- Your site is included in a curated “roundup” of resources on a topic
Building a genuine reputation for editorial backlinks means consistently publishing content that’s genuinely worth citing — original research, clear explanations, or useful data — rather than chasing links directly.
2. Guest Blogging Backlinks
Writing genuinely useful guest articles for relevant, reputable sites in your niche — with a natural link back to your own site included where it adds value — remains a legitimate way to build backlinks. The key distinction from a link scheme is quality and relevance: a well-written guest post on a topically related, reputable site is very different from mass-submitting low-effort articles to dozens of unrelated sites purely for the link.
3. Acknowledgement Backlinks
These occur when your company is mentioned in connection with sponsoring an event, speaking at a conference, or similar public involvement in your industry. Because the link sits within a genuine acknowledgement rather than a paid placement, it tends to carry real value — but this type of backlink is earned through actual industry participation, not manufactured.
4. Dofollow Backlinks
Dofollow is the default link type — when no special attribute is added, a link tells search engines “I trust this destination enough to pass authority to it.” Most organic, editorially earned links are dofollow by default.
5. Nofollow Backlinks
A nofollow link includes the HTML attribute rel="nofollow", which tells search engines not to pass ranking authority through that specific link — commonly used for sponsored content, user-generated comments, or links a site owner doesn’t want to formally endorse. A healthy backlink profile naturally includes a mix of both dofollow and nofollow links, since an all-dofollow profile can look artificially engineered.
6. Backlinks from Free Tools or Resources
Creating a genuinely useful free tool, template, or resource can naturally attract backlinks from people who find and want to reference it. This works because the resource itself provides real value — not because of any link-exchange arrangement — making it one of the more sustainable, low-risk link-building strategies.
7. Badge Backlinks — Use With Caution
Some businesses create “award” or “featured” badges for other brands to display, with a link back to the issuing site. This can work when the recognition is genuine and the badge is optional for the receiving site to display — but if it’s primarily a mechanism for generating backlinks rather than genuine recognition, it risks resembling a link scheme under Google’s spam policies. If you use this approach, make sure the recognition itself has real substance and the link isn’t the main point of the exchange.
8. Comment Backlinks — Use Sparingly and Genuinely
Leaving genuinely relevant, substantive comments that happen to include a link can occasionally be acceptable — but comment links added purely for SEO value, especially at volume, read as spam to both readers and search engines, and can actively hurt your reputation and rankings rather than help them.
Backlink Types at a Glance
| Type | Value | Risk Level |
|---|---|---|
| Editorial | Very high | Very low — genuinely earned |
| Guest blogging (quality-focused) | High | Low, if genuinely relevant and well-written |
| Acknowledgement | High | Low — tied to real industry participation |
| Free tool/resource | High | Low — earned through genuine utility |
| Badge exchange | Moderate | Moderate — risky if link-motivated rather than genuine |
| Comment links | Low | Moderate–high if overused or irrelevant |
| Paid/manufactured links | Low or negative | High — can violate Google’s spam policies |
Anchor Text: Why the Linking Words Matter
Anchor text is the clickable phrase used for the link. It gives search engines a strong contextual clue about what the linked page is about, which is why anchor text diversity matters: if every backlink to your site uses the exact same keyword phrase, it looks engineered rather than natural — a pattern search engines are specifically designed to detect and discount.
When reviewing your backlink profile, ask:
- Is the anchor text genuinely relevant to the page it links to?
- Would a reader find real value clicking through, or does it look purely transactional?
A natural backlink profile includes a healthy mix — brand names, generic phrases (“click here,” “this article”), partial matches, and only occasionally exact-match keyword phrases — rather than the same target phrase repeated across every link.
Quality and relevance matter more than volume in backlink building. Focus on creating content genuinely worth citing, build real industry relationships, and treat any tactic that feels like it’s manufacturing links rather than earning them as a risk to your long-term rankings, not a shortcut to them.
Frequently Asked Questions
-
What are backlinks in SEO?
Backlinks, also called inbound links, are links from one website to another. They act as a trust signal to search engines about your content’s credibility and relevance.
Why are high-quality backlinks important?
Backlinks from reputable, relevant sites signal that your content is valuable and trustworthy, contributing to better search rankings — while low-quality or manipulative links can do the opposite.
How do editorial backlinks benefit a website?
Editorial backlinks are earned naturally within another site’s content because your page adds genuine value, making them the highest-value, lowest-risk type of backlink.
What is the difference between dofollow and nofollow links?
Dofollow links (the default) pass ranking authority to the linked page, while nofollow links (marked with rel=u0022nofollowu0022) explicitly tell search engines not to. A natural backlink profile includes both.
Can guest blogging still help SEO?
Yes, when done on genuinely relevant, reputable sites with well-written content — mass guest posting purely for links, on the other hand, resembles a link scheme and carries real risk.
What are acknowledgement backlinks?
Links from other sites that mention your brand in connection with genuine industry participation, such as event sponsorship or conference speaking.
Are comment backlinks a good SEO strategy?
Only in moderation and when genuinely relevant — comment links added purely for SEO value, especially at scale, read as spam and can hurt your reputation and rankings.
Why does anchor text diversity matter?
Search engines can detect when the same exact-match phrase is used across most backlinks, which looks engineered rather than natural — a diverse mix of anchor text looks more organic and is safer long-term.
Are all types of backlinks treated equally by Google?
No — editorial and genuinely earned backlinks carry significant value, while paid links, link schemes, and manufactured badge exchanges carry real risk of violating Google’s spam policies.
What’s the safest overall approach to backlink building?
Focus on creating content genuinely worth citing, build real relationships in your industry, and treat any link-building tactic that feels manufactured as a long-term risk rather than a shortcut.
