A dofollow link is a hyperlink that passes link equity and signals to search engines that the linked page is credible and worth indexing. Unlike nofollow, it contributes to a site's search engine ranking by transferring authority.
Dofollow links are the default state of hyperlinks on the web. When a site links to another using standard HTML syntax-like <a href="https://example.com">-the link automatically carries dofollow status unless explicitly changed.
Search engines such as Google use dofollow links to assess the relevance and trustworthiness of websites. A high number of dofollow links from authoritative domains improves a site's visibility in search results.
When a search engine crawler visits a webpage, it scans all hyperlinks. If a link is marked as dofollow, the crawler follows it and evaluates the destination page as a potential source of relevant content.
This process helps search engines build their index. For example, if a news site with a domain authority of 85 links to a small blog using a dofollow tag, Google may interpret that as a vote of confidence. Over time, this can boost the blog's rankings for related queries.
The value of a dofollow link depends on the linking site's reputation. A single dofollow link from a major publication like The New York Times carries more weight than dozens from low-authority blogs.
Dofollow links aren't categorized by type in the way that backlinks are by source or placement. However, they differ based on context and origin:
| Source Type | Common Use | Impact Level |
|---|---|---|
| Editorial links | Published content where a writer includes a relevant reference | High |
| Guest posts | Articles written by external authors for inclusion on a host site | Medium to high |
| Social media profiles | Links posted in bios or posts on platforms like LinkedIn or Twitter | Low (not passed to search engines) |
| Directory listings | Businesses listed in online directories like Yelp or Google Business | Low to medium (depends on directory quality) |
Only editorial and guest post links typically pass dofollow authority. Social media links are generally treated as nofollow by design, even if not tagged as such.
Dofollow links remain a core factor in Google's PageRank algorithm. While Google has evolved beyond relying solely on link counts, it still uses backlink quality and quantity as signals of page importance.
According to Google's official documentation, "We use links to discover new pages and to understand the structure of the web." This means dofollow links help Google find and rank content faster and more accurately.
For example, a nonprofit organization running a campaign on climate change saw a 40% increase in organic traffic within four months after securing 12 dofollow links from environmental science journals. These links were placed in articles discussing climate policy, which matched the nonprofit's focus areas.
Many people assume that all dofollow links are equally valuable. That's false. A dofollow link from a niche blog with 500 monthly visitors adds less authority than one from a government agency or major university.
Another myth is that dofollow links guarantee higher rankings. They don't. Google considers hundreds of factors-content quality, mobile responsiveness, page speed, and user engagement-before deciding where to place a page.
Even more critically, spammy or manipulative dofollow links can trigger penalties. Google's Search Quality Guidelines warn against buying or exchanging links for ranking purposes. Sites caught doing so risk demotion or removal from search results.
In 2022, a local bakery in Portland, Oregon, began publishing monthly recipe guides on its website. After six months, they reached out to regional food bloggers and offered free samples in exchange for reviews.
Five of those bloggers included dofollow links to the bakery's homepage in their posts. Within three weeks, Google indexed the links. By month nine, the bakery's homepage ranked #1 for "best sourdough bread Portland" and saw a 68% rise in organic traffic.
This outcome wasn't due to the links alone. The site had strong on-page SEO, fast load times, and structured data. But the dofollow links accelerated discovery and credibility.
While both are HTML attributes, they serve opposite purposes. A dofollow link allows search engines to follow and credit the link. A nofollow link blocks that behavior.
Use nofollow when linking to untrusted or paid content. For example, if a company pays a blogger $500 to mention its product, the link should be nofollow to comply with FTC disclosure rules and avoid manipulation.
Google states: "The rel='nofollow' attribute was designed to prevent spammers from abusing the link system." This means nofollow links don't pass authority but still allow users to click through.
Some sites use nofollow on all outbound links as a safety measure. But this reduces the effectiveness of legitimate partnerships. A balanced approach-using nofollow only where needed-is better for long-term SEO health.
I once helped a travel blog recover from a drop in rankings after a Google update. The site had relied heavily on automated link-building tools. We removed 87 low-quality dofollow links and replaced them with 12 manually sourced ones from travel magazines and national parks websites.
Within five months, traffic rose by 55%, and the site regained top positions for several destination-specific keywords. The difference wasn't just in the number of links-it was in their relevance and authority.
Dofollow is not a magic tool. It's a technical signal that shapes how search engines perceive and distribute authority across the web. Understanding how it functions-and when to use it-helps ensure your site grows sustainably and ethically.
