What Is Follow In SEO

A follow link in SEO is a standard hyperlink that search engines can crawl and treat as a normal editorial signal. It is the default type of link on the web, carrying no special attribute that tells crawlers to ignore it. The term is often used interchangeably with “dofollow,” but dofollow is SEO shorthand, not a real HTML attribute.

The reason the distinction matters is that beginners frequently try to add a “dofollow” tag to their pages, or buy “dofollow backlinks,” without realizing there is nothing to add. What matters is what is not on the link. If a hyperlink has no restrictive rel attribute, search engines treat it as follow by default.

This guide clears up the misconception, walks through how follow links actually work, and explains where they differ from nofollow in practice.

‘Dofollow’ Is a Nickname, Not a Real HTML Tag

Walk into any SEO forum and you will see “dofollow” used as if it were an attribute you can paste into your HTML. It is not. The HTML specification, as documented by MDN’s reference for the anchor element, defines a small set of rel values such as nofollow, sponsored, and ugc. There is no dofollow value. The word is a piece of SEO shorthand that took on a life of its own.

A link qualifies as “follow” only by the absence of restrictive rel attributes. An <a href="..."> tag with nothing else attached is a follow link. Add rel="nofollow", rel="sponsored", or rel="ugc", and you change what crawlers are told to do. Search engines evaluate the lack of a restrictive hint, not the presence of a positive “dofollow” signal. MDN’s documentation on the rel attribute covers this directly.

The practical takeaway is straightforward. Stop trying to add a tag that does not exist. Focus instead on whether your links need a rel value at all, and if so, which one fits the link’s purpose.

How Follow Links Work Behind the Scenes

Search engine crawlers discover the web largely by following links from page to page. A follow link is simply a normal step in that discovery loop. When a crawler hits your page, it parses the HTML, extracts every outbound link, and decides what to do with each one based on its attributes and the surrounding context.

For a follow link, the crawler can fetch the destination URL, parse its content, and consider it for indexing. The link is also recorded as a connection between the source page and the destination page, which feeds into how search engines model relationships, relevance, and authority across the web. The general sequence looks like this:

Crawl the source page → parse its links → identify follow links → fetch destinations → record the connection → evaluate the destination for indexing and ranking.

Where the link sits changes what it does. Internal follow links shape how crawlers move through your own site, which pages get discovered, and how topical structure is communicated. External follow links act as editorial citations, one site pointing at another because the content genuinely references it. In both cases, the anchor text matters: it gives the crawler a topical signal about what the destination page is actually about.

Follow vs Nofollow: Where They Actually Differ

The difference between follow and nofollow lives entirely in the rel attribute and how search engines interpret it.

What the rel attribute actually changes

A follow link is an <a> tag with no restrictive rel value. A nofollow link adds rel="nofollow" to that same tag. That is the only HTML-level difference. The rel attribute is a hint to crawlers, not a firewall, as described in Google’s documentation on qualifying outbound links. Search engines can still see, crawl, and in some cases index a nofollow link. Google has publicly stated that nofollow, sponsored, and ugc are treated as hints rather than absolute rules.

What this means in practice

Translated into real-world SEO impact, the two behave differently in three concrete ways.

• Follow links can be freely crawled and may be considered as part of link-based ranking signals.
• Nofollow links still send referral traffic, brand visibility, and indirect SEO value, even when they do not behave as standard editorial endorsements.
• A natural link profile usually mixes both, because real editorial citations are not uniform.

Nofollow links are not worthless. They can drive real clicks from real readers, expose your brand to new audiences, and sometimes lead to follow links later. The myth that they offer zero value causes marketers to ignore placements that would have helped them.

When to Use Follow Links (and When Not To)

Use follow links for genuine editorial references, internal navigation, and resources you actually stand behind. Most links on a typical site should be follow by default. The decision changes when the link is not purely editorial, which is when a different rel value earns its place:

• Sponsored when the link exists because of payment, advertising, or affiliate compensation.
• UGC when the link is user-submitted in comments, forum posts, or similar areas.
• Nofollow selectively, for untrusted external content or links you do not want to endorse editorially.

One common mistake is over-tagging internal links with nofollow, which can hide important pages from crawlers and quietly damage site architecture. Google’s link spam policies make clear that paid or affiliate links should be marked accordingly, but ordinary editorial and navigational links should not.

The One Thing to Remember About Follow Links

A follow link is just a normal link. There is no special tag to add, no toggle to flip, and no SEO attribute that makes a link “more follow.” The real work is choosing the right rel value for links that are not editorial endorsements, not chasing a dofollow label.

Next step: open a few of your most important pages, inspect the HTML on your outbound and internal links, and confirm that genuine editorial links are plain follow while paid, affiliate, and user-submitted links are properly tagged. That single audit usually surfaces more SEO wins than any backlink campaign.
