Are link exchanges safe for SEO?

What the policy says

Google's spam policies list examples of link spam. One of them reads: "Excessive link exchanges ('Link to me and I'll link to you') or partner pages exclusively for the sake of cross-linking."

The words doing the work are "excessive" and "exclusively". Google does not define either. Nothing in the policy says two businesses may not link to each other. It says links made mainly to manipulate ranking are spam, and gives exchanges at scale as an example.

The same page says buying and selling links is acceptable when the link is marked with rel="sponsored" or rel="nofollow", which tells Google not to count it.

What raises the risk

The policy does not rank these. This is our reading of which patterns are easiest to spot and hardest to defend.

Direct swaps. Site A links to B and B links to A in the same week. It is the plainest footprint there is.

Volume from one place. Dozens of links arriving from the same small group of sites.

No topical connection. A dental practice linking to a crypto exchange. Ask whether a reader of the first page would have any use for the second.

A link dropped into a sentence written to hold it. "For more information, check out [best running shoes 2026]." The sentence exists for the link, and it reads that way.

Keyword-stuffed anchor text. The same commercial phrase as the clickable words, again and again.

Links in places nobody reads. Footers, sidebars, "partners" pages.

The rules our exchange enforces

Here is what the software does, so you can judge it. Each of these is enforced in code, not left to judgement:

• It is opt-in, per site. It is off until you turn it on.
• Two sites with the same owner are never matched.
• Both sites must write in the same language.
• A link may only be made from words already in a sentence of the finished article. If no existing sentence supports the link, the placement is skipped. Nothing is written to hold a link.
• No direct swaps: after A links to B, B cannot link to A for 14 days, and A cannot link to B again in that time.
• At most 12 links in each direction between any two sites in a year.
• Credits move only once the link has been found live on the page, and are returned if the link later disappears.

What those rules do not do

They lower the risk. They do not remove it. An exchange run by software across many sites is the kind of arrangement the policy has in mind, and we cannot promise Google will never treat links from it as ones to ignore. In our reading, the likely outcome of a link Google distrusts is that it is not counted. The worst is a manual action against a site that has leaned on such links heavily.

If you would sooner not carry that risk, leave the exchange off. Everything else in the product works without it.

Links nobody can object to

These are slower, and they are the ones that last.

Publish something worth citing. A number you measured, a tool, a clear explanation of something confusing. We built free tools and ran a small robots.txt study partly for this reason: people link to things they can use.

Get onto the pages that already list businesses like yours. Comparison articles, directories for your trade, review sites. Email the author with one specific reason you belong there.

Be a source. Answer questions in your field under your own name, in forums and for journalists. The link follows the usefulness.

How to vet a site before exchanging with it

Whether through an exchange or by email, look at the other site first. Does it publish for readers, or is every article a container for outbound links? Does it rank for anything? Would its visitors care about your page? Would you be comfortable if a customer saw the link? If any answer is no, pass.
