What is a link scheme?

Link scheme, explained

"Link schemes" was Google's long-standing name for this; its current spam policies call it link spam. The definition is the practice of creating links to or from a site primarily for the purpose of manipulating search rankings. Intent is the test: a link that exists because it helps readers is fine, a link that exists to move rankings is not.

Google's policy gives concrete examples. Buying or selling links for ranking purposes, including exchanging money, goods or services for links. Excessive link exchanges, or partner pages built only to cross-link. Using automated programs or services to create links to your site. Paid articles or guest posts with keyword links that aren't qualified. Optimized links stuffed into forum comments or signatures.

Two things are explicitly fine. Advertising links are allowed as long as they carry rel="sponsored" or rel="nofollow". And ordinary cross-linking between related sites is normal; the policy targets excessive exchanges and link-for-link arrangements.

What happens if you're caught up in one? Most often, nothing visible: Google's systems neutralize the links and they stop counting. If your rankings depended on them, they fall. In more serious cases, Search Console shows a manual action for unnatural links, and fixing it means removing or nofollowing the links, disavowing the rest and filing a reconsideration request.

The newer versions are harder to spot because they're packaged as features. Some AI SEO tools include a network where customers' sites automatically link to each other. Some launch platforms give a followed link only if you place their badge with a link back. Each link might look harmless; the pattern across thousands of sites is what matches the policy.

Why it matters for founders

Cheap link programs are easy to buy and easy to rationalize. For a young domain they're also the fastest way to waste months: the links get discounted, and you've built on something that doesn't count.

Example

An SEO tool offers to "automatically build backlinks" by placing links to your site in other customers' articles in exchange for links to theirs. That's both an automated link program and a link exchange under Google's examples.

Common mistakes

• Treating "it's a network of real sites" as proof that an exchange is safe.
• Buying guest posts with keyword anchors and no sponsored attribute.
• Assuming no manual action means the links are working. They may simply be ignored.
• Removing good, natural links out of fear. Normal cross-linking is fine.
