    What is Dofollow Links and Search Engines? | Definition & Guide

    A dofollow link is a standard hyperlink that passes link equity (also called "link juice" or PageRank) from one website to another — signaling to search engines that the linking site endorses the target page and contributing to its authority and ranking potential.

    Definition

    A dofollow link is a standard hyperlink that passes link equity (also called "link juice" or PageRank) from one website to another — signaling to search engines that the linking site endorses the target page and contributing to its authority and ranking potential. By default, all hyperlinks on the web are dofollow unless explicitly marked otherwise with a rel="nofollow", rel="sponsored", or rel="ugc" attribute. The dofollow designation tells search engine crawlers to follow the link, discover the target page, and factor the link into their ranking algorithms as a positive signal of trust and relevance.

    Why It Matters

    Dofollow links are one of the most important ranking factors in search engine algorithms. Google's original PageRank algorithm was built on the premise that links between pages function as votes of confidence — and dofollow links are the links that count as full votes. While search algorithms have evolved far beyond simple link counting, the fundamental principle remains: high-quality dofollow links from authoritative, relevant websites significantly improve a page's ability to rank in search results.

    For B2B SaaS companies, understanding the distinction between dofollow and nofollow links is essential for evaluating link building opportunities and assessing backlink profiles. A link from a major industry publication that uses a dofollow attribute passes meaningful authority to the linked page, while the same link with a nofollow attribute provides referral traffic and brand visibility but limited direct ranking benefit.

    The practical impact is significant. A SaaS company's product page with 50 dofollow links from authoritative domains will, all else being equal, substantially outrank a competitor's page with the same content but only 5 dofollow links. This makes dofollow link acquisition a core component of competitive SEO strategy — particularly for high-intent commercial keywords where ranking positions directly translate to pipeline.

    How It Works

    Dofollow links influence search engine rankings through a well-established mechanism:

    1. Link equity transfer. When Site A places a dofollow link to Site B, a portion of Site A's authority (often conceptualized as PageRank, though Google's actual algorithm is more complex) flows to Site B. The amount of equity transferred depends on Site A's own authority, the number of other outbound links on the page, and the relevance of the linking content to the target page.

    2. Crawling and discovery. Search engine crawlers follow dofollow links to discover new pages and understand the web's link graph. A new page with no dofollow links pointing to it may take significantly longer to be crawled and indexed than a page with several dofollow links from well-crawled domains.

    3. Anchor text signals. The clickable text of a dofollow link (anchor text) provides search engines with additional context about the target page's topic. A dofollow link with the anchor text "B2B SaaS marketing platform" sends a relevance signal that the target page is about B2B SaaS marketing. Diverse, natural anchor text distribution across a page's dofollow link profile strengthens topical relevance without triggering over-optimization penalties.

    4. Link quality evaluation. Not all dofollow links are equal. Search engines evaluate link quality based on the linking domain's authority, the topical relevance between the linking and target pages, the editorial context of the link (was it placed naturally within content or in a blogroll sidebar?), and the overall trust profile of the linking site. A single dofollow link from the Wall Street Journal carries more weight than hundreds of dofollow links from low-authority directories.

    5. Dofollow vs. nofollow in practice. Most editorial links (links within published articles, blog posts, and resources) are dofollow by default. Nofollow attributes are typically applied to user-generated content (blog comments, forum posts), paid placements, press release links, and social media links. Google introduced additional link attributes in 2019 — rel="sponsored" for paid links and rel="ugc" for user-generated content — though Google treats these as hints rather than strict directives.

    6. Link building strategies for dofollow acquisition. Earning dofollow links requires creating content worth linking to: original research, comprehensive guides, free tools, and expert commentary. Guest posting, digital PR, broken link building, and strategic partnerships are common tactics for acquiring high-quality dofollow links in B2B SaaS.
