Dofollow or nofollow: what actually changes

A link either passes authority or it does not. An eight-letter attribute in the HTML separates a placement worth three months of negotiation from a mention that brings a handful of visitors. None of it is visible on screen: you have to look at the page source, which is exactly why a link switching over almost always goes unnoticed.

What the attribute does

A normal link looks like this:

<a href="https://your-site.com">your brand</a>

Add rel="nofollow" and the page is telling search engines: I am linking to this, but do not treat it as an endorsement.

<a href="https://your-site.com" rel="nofollow">your brand</a>

Nothing changes for a human. The link is the same colour, in the same place, and clicking it works exactly as before. The difference is invisible on screen and decisive for your ranking.

The full family, and what each value signals

Since 2019 search engines have treated these attributes as hints rather than orders. The nuance matters less than it sounds: in practice a marked link is very rarely counted as an endorsement.

Those last two values appear constantly on perfectly followed links. Mistaking them for a nofollow is the most common analysis error there is, and it causes a lot of pointless panic.

When nofollow is legitimate

It is not an insult, and a partner who uses it is not aiming at you.

• User-generated content: comments, forums, profile fields. Without nofollow, any site with an open form becomes a target.
• Paid placements: advertising, sponsorship, affiliate links. Search engines expect these to be marked, and it is the failure to mark them, not the payment, that gets sites penalised.
• Pages the site does not vouch for: a link inside a quote, a source it disagrees with, a screenshot of something it is criticising.
• Industrial volume: a site publishing a hundred outbound links a day cannot vet each one, and a blanket nofollow is its only reasonable defence.

Checking in thirty seconds

Three methods, from fastest to most reliable:

curl -s https://example.com/article | grep -o '<a[^>]*your-site\.com[^>]*>'

The command returns the whole tag, attributes included. Without a terminal, the page source in your browser and a search for your own domain name gives the same answer. A browser extension that colours nofollow links is fine for a glance, but it keeps no record, which is the point where manual checking stops being enough.

Whatever the method, write the answer down somewhere with the date. A check whose result you do not keep tells you the state today and nothing at all about the change, and the change is the entire subject of this article. Two identical observations three months apart are worth more than one very thorough audit.

Why a switch matters more than a placement

Getting a link is a project. Losing its value is an accident, usually someone else's.

The typical sequence: a partner installs a security plugin that adds nofollow to every outbound link. Or a new editor changes the CMS default. Or the site is rebuilt and the template no longer carries the original attributes. Your link survives the change; its value does not.

Nobody tells you. The partner does not know it happened. The search engine simply adjusts your position over the following weeks. You notice, if you ever do, months later, while looking for something else entirely. This is precisely the pattern backlink monitoring exists to catch, and the one an occasional eyeball check never recovers.

What a nofollow does not destroy

This needs saying, because panic is the wrong reflex.

A nofollow link still sends traffic, and traffic is not up for debate: those are people. It still puts your brand in front of readers who did not know you. It is still a discovery path for crawlers. And on a heavily read site it is often worth more than a followed link on an empty page.

A nofollow link in an article read by twenty thousand people is not a failure. A followed link on a "partners" page nobody opens is, and that is the real question about the quality of a link.

The particular case of paid links

A link that was bought and marked sponsored is in order. A link that was bought and left as an ordinary link is a bet: it pays as long as nobody notices, and it costs a great deal the day somebody does. The imbalance is structural, since the risk sits with the buyer and not with the seller.

Two practical consequences. First, a seller promising "guaranteed dofollow" is really selling the act of not declaring a paid link, which is exactly the practice search engines are looking for. Second, a paid link that switches to sponsored one day is not recoverable: that is the seller coming into compliance, not an oversight on their part.

If paid links appear in your tracking, mark them as such from day one, with the amount and the date. A spreadsheet holds that kind of record very well, better than any automated tool, because that information exists nowhere on the page.

Three ideas that still circulate

"Nofollow is useless." It is useful to the site placing it, which is reason enough for it to exist. It deprives you of a signal, not of a reader.

"A profile with a lot of nofollow looks suspicious." The opposite is closer to true: a profile where absolutely everything is followed looks constructed. Comments, forums and press mentions naturally produce marked links, and their complete absence is more noticeable than their presence.

"Making internal links nofollow saves something." That practice was useful fifteen years ago, inside a mechanism that no longer exists. Today it does exactly one thing: it cuts circulation inside your own site.

What to do about it

Check the attribute, not just the presence of the link. A monitoring tool that only asks "is the link still there?" will report that all is well on the day your best placement quietly stops counting.

Record the value you found, get an alert when it changes, and then decide case by case. Asking the partner works better than people expect, provided you do not talk about SEO:

Hello, I noticed the outbound links in your articles now carry a nofollow, probably since a security plugin was installed. Not a problem at all, but if the link to our guide still seems useful to your readers, it would be better off as an ordinary link.

Above all, do not treat a nofollow as a toxic link. A marked link has nothing to do with a harmful one, and the disavow file has no business with it.

The attribute is only one of the three signals that travel with every link. Recording one of them and guessing at the other two is how people end up surprised. The other two are whether it deserves to be there and what its anchor text says about you: recording all three at once costs the same effort as recording one.
