Types of Backlinks: Dofollow vs Nofollow, Editorial vs Contextual

A dofollow backlink is the default HTML link type. It passes authority — often called link equity — from the linking page to yours. A nofollow link includes rel="nofollow" in its tag, telling search engines not to treat the link as an endorsement for ranking purposes. Google also uses rel="sponsored" for paid links and rel="ugc" for user-generated content. These attributes are the raw mechanics, but they don't tell the whole story about a link's value.

I see a lot of SEOs dismiss nofollow links entirely. That's a mistake. A nofollow link from the New York Times can drive more referral traffic than a dofollow link from a random blog. And Google has repeatedly said that nofollow links can still influence ranking indirectly — through traffic, brand signals, and natural link velocity. The real question isn't dofollow vs nofollow; it's relevance and placement.

The sweet spot is a link that is both editorial and contextual. That means someone chose to link to your resource because it fit naturally into their article. That type of link carries the strongest relevance signal, and it's the hardest to fake. Most link schemes fail because they skip the editorial layer — they place links for money or exchange without considering whether they actually belong.

Not all backlinks are created equal. Below is my ranking, from strongest to weakest, based on authority passed, acquisition difficulty, and risk. I've excluded pure spam like PBNs and automated comment links because they don't belong in a sustainable strategy.

1. Dofollow editorial contextual links — The benchmark. Earned from a relevant page, within body text, with no paid or manipulative strings attached.
2. Dofollow editorial but non-contextual links — Still high value, but placement in sidebars or resource lists slightly dilutes relevance.
3. Dofollow contextual non-editorial links (e.g., paid guest posts with proper attribution) — Acceptable only if marked with rel="sponsored" and the content is high quality. See guest posting guidelines.
4. Nofollow editorial contextual links — Drive referral traffic and brand awareness. Essential for a natural profile.
5. Dofollow directory and profile links — Low effort, low value. Only useful for niche-specific, curated directories.
6. Nofollow contextual non-editorial links (e.g., forum signatures, blog comments) — Minimal SEO value. Useful only for traffic if the community is active.
7. Automatic or scraped links (e.g., article submissions, bookmarking sites) — Very low value, often flagged by Google. Avoid.

Earning dofollow editorial contextual links requires a strategy that combines quality content with targeted outreach. The most effective methods I've seen include digital PR (pitching data or stories to journalists), broken link building (offering your content as a replacement), and brand mention building (converting unlinked mentions into links).

Guest posting still works if you focus on relevance and value — not on dumping links into low-quality accept-all sites. Same with HARO and similar services: the key is to respond quickly with genuinely useful information. Paid link acquisition has its place, but it must be transparent. I cover that in Buy Backlinks with a warning: never buy links that are marked as dofollow unless the seller explicitly labels them as sponsored.

Google's link spam policies are clear: paid links that pass PageRank must be marked with rel="sponsored". Violations can lead to manual actions or ranking drops. Other high-risk practices include excessive reciprocal linking, using private blog networks (PBNs), and automated link creation.

Even low-risk methods can become harmful if done at scale. A sudden flood of dofollow links from irrelevant sites is a pattern that Google's algorithms detect. The safest approach is to diversify your link profile — mix dofollow and nofollow, include earned and properly attributed paid links, and maintain a natural growth curve. I recommend running regular audits with backlink audit tools to catch problems early.

To build a safe and effective backlink profile, start with relevance over authority. A link from a niche-relevant site with moderate DA is worth more than a random high-DA page from a different industry. Contextual placement matters more than the attribute — a nofollow link inside a well-written article beats a dofollow link in a footer.

Be transparent with paid links. Use rel="sponsored" without exception. Audit your link profile quarterly using backlink profile tools to identify unnatural patterns. And remember: the best link is the one you never had to ask for — because someone found your content genuinely useful. That's the foundation of high-quality backlinking.
