Dofollow backlinks are hyperlinks that allow search engines to follow the connection from one website to another, passing SEO value and contributing to the linked site's authority and ranking potential. These links are the default setting in HTML and are essential for improving visibility in search results.
When a website includes a <a href="https://example.com">link text</a> without the rel="nofollow" attribute, it creates a dofollow backlink. Search engines like Google interpret these links as endorsements, using them to assess relevance, trustworthiness, and popularity of the destination page.
For example, if a tech blog with high domain authority links to a small e-commerce store using a standard anchor tag, Google treats that as a vote of confidence. This can boost the store's ranking for relevant queries like "best wireless headphones under $100."
Search engines crawl web pages and index their content. During this process, they analyze every hyperlink on a page. Dofollow links signal to crawlers that the linked page is relevant and trustworthy. The more high-quality dofollow links a page receives, the higher its perceived authority.
Google's PageRank algorithm, introduced in 1998, was built around this principle. While modern ranking systems are far more complex, the core idea remains: inbound links from reputable sites act as signals of credibility. A single dofollow link from a site like Forbes or Harvard University can carry more weight than dozens from low-authority domains.
Backlinks also influence how quickly a page gets indexed. A newly published article with multiple dofollow links from established news outlets may appear in Google Search within hours, while a similar page with no external links may take weeks to surface.
Dofollow backlinks vary in strength based on the source's authority, relevance, and context. Not all dofollow links are equal. The following table outlines common types and their relative effectiveness:
| Type | Authority Level | Relevance Factor | Typical Impact on Rankings |
|---|---|---|---|
| Editorial links from major publishers (e.g., The New York Times) | High | High | Strong positive effect |
| Guest posts on niche-relevant blogs with moderate traffic | Medium | High | Moderate improvement |
| Forum signatures or comment links on low-traffic sites | Low | Low | Negligible or harmful if spammy |
| Social media shares (e.g., Twitter, LinkedIn) | Variable | Low | Indirect influence via traffic and engagement |
One non-obvious fact: Google does not count every dofollow link equally. The algorithm evaluates the context of the link-such as surrounding text, placement on the page, and whether the linking site is editorially independent. A dofollow link embedded in a sponsored post or paid review may be discounted or ignored entirely.
For example, a travel blog received 12 dofollow backlinks from industry directories. After six months, the site's organic traffic increased by 42%. However, when Google updated its spam detection system, several of those links were flagged as part of a link scheme. The site lost 60% of its traffic within two weeks. This illustrates that not all dofollow links are safe or beneficial.
Many people assume that more dofollow backlinks always lead to better rankings. This is false. Quantity without quality triggers penalties. Google's Spam Brain algorithm specifically targets unnatural link patterns, including rapid increases in backlinks from unrelated or low-quality domains.
A common error is buying dofollow links through black-hat SEO services. These often come from link farms or automated networks. In 2022, Google penalized over 15,000 websites for such practices, resulting in dropped rankings or removal from search results altogether.
Another misunderstanding is equating dofollow links with direct traffic. While a dofollow link can improve visibility, it doesn't guarantee clicks. A well-placed link on a high-traffic site may generate thousands of visits, but only if the anchor text and landing page align with user intent.
I once ran a test where we created 50 dofollow backlinks from low-authority sites to a product page. Despite the volume, the page's bounce rate rose from 41% to 68%, and conversions dropped by 33%. The links didn't drive meaningful traffic because the referring sites had no audience overlap with our target market.
Focus on earning dofollow backlinks from sites in your niche with real readership. Use tools like Ahrefs or Moz to identify domains with high Domain Rating (DR) and relevant content. Outreach to editors with personalized pitches that offer value-such as original research or expert commentary.
For instance, a SaaS company improved its search ranking for "project management software" by securing dofollow links from 14 industry blogs. Each link came from a guest post that included a data-backed comparison of five tools. The result: a 78% increase in organic traffic over nine months.
Always audit your backlink profile regularly. Tools like Google Search Console flag suspicious links. Remove or disavow toxic ones using Google's Disavow Tool to avoid penalties.
Dofollow backlinks remain a core component of SEO strategy. They are not a shortcut, but a long-term investment in credibility and discoverability. Prioritize relevance, authority, and user intent over sheer volume.
Understanding what are dofollow backlinks is the first step toward building a sustainable online presence. Focus on creating valuable content that others want to link to naturally. That's the foundation of lasting SEO success.
