A 3-way link exchange (also called ABC linking) is a deal between three sites where Site A links to Site B, and Site B’s owner pays that back with a link from Site C to Site A. Nobody links straight back to anyone, so it looks less like a swap. That’s the whole point of the setup.
Here’s the short answer most people are after: it’s still a link exchange. Google’s spam policies list “excessive link exchanges” and “partner pages exclusively for the sake of cross-linking” as link spam, and adding a third site doesn’t change what the deal is. Below I’ll explain how these swaps work, why the benefits are usually oversold, and what I’d do instead.
How a 3-way link exchange works
In a normal two-way swap, two sites link to each other. That pattern is easy to spot, so the three-way version spreads the links across more sites:
| Type | Who links to whom | How easy it is to spot |
|---|---|---|
| Two-way (reciprocal) | A links to B, B links to A | Very easy. The links point straight back at each other. |
| Three-way (ABC) | A links to B, C links to A. The owner of B usually also owns or controls C. | Harder at a glance, but the same sites keep showing up together. |
| Natural link | A links to B because B’s page is useful. Nothing is owed. | Nothing to spot. This is what Google wants links to be. |
Most of the 3-way offers I see come from cold emails. The sender has a “money site” they want links to, plus a few blogs they use as the “C” site to pay you back. If you’ve ever had an email saying “I can’t link back from the same site, but I’ll give you a link from one of my other blogs,” that’s a 3-way exchange.
Why people still do them
The appeal is easy to see. Links still matter for rankings, earning them takes time, and a swap feels free. The pitch usually promises three things:
- Higher rankings from more inbound links
- Referral traffic from the partner sites
- Better authority scores in tools like Moz or Ahrefs
The problem is that each of these is weaker than it sounds.
The real risks
It breaks Google’s rules
Google defines link spam as creating links mainly to manipulate rankings. A link you only placed because someone promised one in return fits that definition, whether it comes back from Site A or Site C. Google can respond with a manual action, or more often, simply ignore the links. Google has said its SpamBrain system is used to detect sites buying links and sites set up to pass outgoing links, and to neutralize those links.
The links often count for nothing
Even when nothing visibly bad happens, swapped links may just be discounted. You’ve spent time on outreach and given away a link from your own site for no measurable gain.
The “C” sites are usually weak
The site you get the link from is often a thin blog that exists mainly to sell or trade links. It may have decent-looking metrics but little real traffic, and its outbound links point to a messy mix of unrelated topics. That’s not a neighbourhood you want to be in.
You hand out links to sites you don’t control
Your side of the deal is a link from your site to theirs. If that site later turns spammy, gets sold or goes off-topic, your page is linking to it.
Authority scores aren’t Google
Domain Authority (Moz) and Domain Rating (Ahrefs) are third-party estimates. Google doesn’t use them. Swaps can push those numbers up without doing anything for your actual rankings.
How to spot a 3-way exchange offer
- The email offers a link from “another site I manage” instead of the one they want a link to.
- They ask for a link to a page that has nothing to do with your topic.
- They mention DA or DR scores but never traffic or audience.
- The site they offer has posts on dozens of unrelated subjects, each with a few outbound links.
- They want a specific anchor text, often an exact keyword.
Any one of these is a warning sign. Two or more and I’d simply not reply.
Is any link exchange OK?
Yes, some linking between sites that know each other is normal. A supplier linking to a stockist, two local businesses that refer customers to each other, or a partner page listing real partners are all fine. The difference is that the link exists because it helps visitors, not because it was traded for rankings, and it isn’t done at scale.
If a link is part of a paid or sponsored deal, Google’s guidance is to mark it with rel='sponsored' or rel='nofollow'. That keeps the relationship visible without trying to pass ranking credit.
What to do if you’ve already done 3-way exchanges
- List them. Check your backlink tool and your own outbound links for sites you swapped with.
- Remove or qualify your outbound links to sites that are low quality or off-topic. You control those, so start there.
- Check Google Search Console for a manual action under Security & Manual Actions.
- Only disavow if you need to. Google’s advice is to use the disavow tool when you have a lot of spammy or artificial links that have caused, or are likely to cause, a manual action. For most small sites, it isn’t needed.
- Stop making new deals and put the time into links you earn instead.
Safer ways to earn links
These take more effort than a swap, but the links last and you won’t have to worry about them later:
- Answer journalist requests. My guide to HARO link building covers how to pitch and where to find requests.
- Publish something worth citing. The skyscraper technique is one way to find topics people already link to.
- Get your local listings right. For local businesses, local citations and real community links often help more than any swap.
- Turn real relationships into real links. Suppliers, associations, sponsors and partners you actually work with often have pages where you belong.
If you’d rather hand this off, my link building service focuses on earned links only, no swaps or paid placements. You can get a rough idea of what ongoing SEO support involves with the SEO cost calculator, or get in touch if you’re unsure whether links you already have are a problem.
FAQ
What is a 3-way link exchange?
It’s an arrangement where Site A links to Site B, and in return Site A gets a link from a third site, Site C, usually owned or controlled by Site B’s owner. It’s designed to look less like a direct swap.
Are 3-way link exchanges safe?
Not really. Google’s spam policies treat link exchanges made for ranking purposes as link spam, and a three-way setup is still an exchange. At best the links get ignored. At worst they contribute to a manual action.
Is a 3-way link exchange better than a reciprocal link?
It’s harder to spot at a glance, but it’s the same deal with an extra step. It also usually means getting a link from a weaker site than the one you’re linking to.
Can Google detect 3-way link exchanges?
Google doesn’t publish exactly how it detects link schemes, but it has said its systems look for sites buying links and sites used to pass outgoing links. Networks that keep linking to the same group of sites leave patterns.
What should I do instead of exchanging links?
Earn links through useful content, press and expert quotes, local citations, and real business relationships. They’re slower, but they keep working.
