Definition:
A DoFollow link is the informal name for a regular HTML link that does not use rel values to limit or qualify how search engines treat it. There is no standard rel="dofollow" attribute: if the link is crawlable, Google may discover and analyse its destination and consider it among its signals, without guaranteeing indexing or higher rankings.

How a DoFollow link is represented
In HTML, a regular link only needs a destination and linked text. For example: <a href="https://. Because it does not include nofollow, sponsored or ugc, it is commonly called a DoFollow link in SEO.
The word DoFollow distinguishes it from qualified links, but it does not add a special instruction to the code. It is also unrelated to whether the link opens in the same tab or a new one: attributes such as target="_blank" control browser behaviour, not the relationship communicated to a search engine.
What it can provide to search engines
A crawlable link connects two resources and provides context through the source page, destination and anchor text. Its treatment is involved in several distinct stages:
- Discovery: A search engine may find a URL that it did not previously know.
- Crawling: A crawler may request the linked resource when its systems and technical directives allow it.
- Interpretation: The link helps relate topics, pages and entities across the web.
- Evaluation: Search systems may consider the link alongside many other signals, but there is no fixed or guaranteed transfer of authority.
Discovering a URL does not mean it will be crawled immediately, crawling does not guarantee indexing, and one link does not determine rankings by itself.
Differences from NoFollow, Sponsored and UGC
Google documents several rel values for explaining the relationship with a destination. The appropriate choice depends on the origin and nature of the link, not on a predetermined ratio:
- Regular link: It needs no
relvalue when Google is expected to crawl and interpret it without qualifications. - NoFollow: It is used when the other values do not apply and the publisher would rather Google did not associate the site with, or crawl, the linked page from that link.
- Sponsored: It identifies advertising, sponsorships and other paid placements.
- UGC: It identifies links added by users, such as those published in comments or forums.
These values can be combined when appropriate. According to Google’s documentation on qualifying outbound links, qualified links will generally not be followed, although the destination URL may be discovered through sitemaps or other links.
Use in internal and external links
The DoFollow label can apply to both internal and external links. In either case, the link should be accessible through an <a> element with a resolvable href attribute.
- Internal links: They connect pages on the same site, support navigation and help represent its architecture and hierarchy.
- External links: They lead to another domain and may attribute a source, extend an explanation or connect related resources.
- Inbound links: From the receiving page’s perspective, an incoming external link is a backlink.
A reciprocal link exists when two sites link to each other. Reciprocity describes the relationship between the two links, but it does not determine whether either one is qualified or regular.
In SEO, the term link juice is used as a simplified description of the influence that a link may pass. It is not an observable or constant percentage: search engines assess factors such as relevance, context, source, anchor text and the overall quality of a link pattern.
Regular links form part of link building, but their value does not depend only on the absence of nofollow. A relevant editorial link may support discovery, context and referral traffic; a link created to manipulate rankings may be ignored or result in action against a site.
Qualification and manipulative practices
The technical classification of a link does not make every acquisition method legitimate. Four situations help explain its correct treatment:
- Editorial reference: A link chosen for its usefulness may remain a regular link.
- Commercial relationship: Paid, sponsored or advertising links should be identified with
sponsoredor, where appropriate,nofollow. - User-generated content: Links added by third parties may use
ugc, either alone or combined withnofollow. - Manipulation: Buying links for rankings, excessive exchanges and automated link creation are among the link spam practices described by Google.
There is no universal ratio of DoFollow to NoFollow links that guarantees a natural profile. What matters is that each link reflects a genuine relationship, is qualified correctly and is useful in context.
