Link exchanges: what Google says, and what people actually do

Two sites linking to each other is normal and always has been. A spreadsheet of swaps between forty founders is what Google's link spam policy calls excessive link exchanges. The difference is whether the link would exist if the other one disappeared, and this page is about telling the two apart.

The policy, in Google's words

Google's link spam policy names "excessive link exchanges" and describes them as arrangements of the form: link to me and I will link to you. It sits in the same list as buying and selling links that pass ranking, large-scale article campaigns with keyword-rich anchors, and automated link programmes.

Two words carry the weight. Excessive means the exchange is the point and the reader is not. And links that pass ranking means the policy is about ranking signals, not about the existence of a link.

Where the line actually sits

One question separates the two cases: would this link exist if the other side removed theirs tomorrow.

ArrangementReading
Your integration page links to their docs; their integrations page lists youBoth links help a user with a real task. Fine.
You cite their study in a guide; they cite your tool in theirsTwo editorial decisions that happen to point both ways. Fine.
A group chat where members post URLs and everyone links to everyoneAn exchange scheme. The pattern the policy describes.
"We will add you to our resources page if you add us to yours"The link is the payment. A swap.
A three-way arrangement so the links are not reciprocal on paperStill an exchange, and a familiar pattern to a spam system.

The three-way version deserves a note because it is sold as the clever workaround. Site A links to B, B links to C, C links to A. It is a scheme with an extra step, and the extra step does not change what it is.

What gets neutralised, and how you would know

You will not get a message. The usual outcome of an exchange network is that nothing happens at all: the links sit there, nobody clicks them, and the rankings do not move.

  • The links are live and indexed, and your positions are unchanged over months.
  • The referring domains chart goes up while impressions stay flat.
  • No traffic ever arrives from any of them, because nobody reads a page of outbound links.
  • In the rare case of a manual action, Search Console's Manual actions report says so explicitly.

That flatness is the signal. It is also why the exchange feels harmless: nothing visibly breaks. The cost is the weeks spent and the pages of outbound links now sitting on your own site, doing nothing for your readers.

The safer version of the same idea

The impulse behind an exchange is sound: you know other founders, and you want to help each other. Keep the impulse and drop the accounting.

  1. Build the integration

    If your products connect, document it on your side. Then ask to be listed on their integrations page. Both pages exist because users need them.

  2. Cite properly

    When their study, tool or documentation is the best reference for a paragraph you are writing, link it. Tell them you did, once, without asking for anything.

  3. Recommend to people, not to crawlers

    Introduce their product to a customer it suits. Recommendations travel further than links and often end up as one anyway.

  4. Share an audience instead

    A joint study, a webinar, a newsletter swap that goes to human subscribers. The link that follows is a byproduct of something real.

Worked example. PingFox monitors uptime; a rival product publishes status pages. PingFox writes a guide on status page reliability and cites their documentation because it is the clearest explanation available. Their team notices, and later lists PingFox on their integrations page because customers ask for it. Two links, no negotiation, both useful to a reader.

How to answer an exchange request

You will get these emails weekly. A short honest answer takes ten seconds and keeps the relationship open.

Hi, thanks for the note. We do not do link exchanges, but I am happy to
link to your guide on retries if it is the best reference when we next
write about that, with no expectation either way. If our products ever
connect properly, an integration page on both sides makes more sense.

  • Do not argue about policy. Say no and offer the version you would do.
  • If they are a genuine peer, the offer is real: add them to your reading when they earn it.
  • If the email lists forty sites and a spreadsheet, do not reply at all.
  • Never agree to a swap because the other site has a high third-party metric. That number is a tool's model, not Google's.
