Link spam, in Google's spam policies, is any link intended to manipulate rankings rather than to genuinely reference or endorse a resource: buying or selling links that pass ranking signals, excessive link exchanges, large-scale article and guest-post campaigns done for links, automated link creation, requiring links as part of a partnership or terms of service, and low-quality directory or bookmark links.
Definition
Link spam, in Google's spam policies, is any link intended to manipulate rankings rather than to genuinely reference or endorse a resource: buying or selling links that pass ranking signals, excessive link exchanges, large-scale article and guest-post campaigns done for links, automated link creation, requiring links as part of a partnership or terms of service, and low-quality directory or bookmark links. Google's link-spam systems aim to neutralise these links (discount them so they neither help nor, usually, hurt), and manual actions can be applied to sites with a pattern of manipulative link building or selling.
The policy's core is the distinction between links that are editorially given because a resource is worth referencing and links that exist because of payment, reciprocity, automation or coercion. Paid and affiliate links are allowed but must not pass ranking signals — they should carry rel="sponsored" or rel="nofollow".
In context
For iGaming affiliates, the link-spam policy is central because the niche's link economy has historically run on exactly the practices it targets: bought guest posts, paid "gambling links" packages, PBNs, expired-domain link sources, and link exchanges. Google's link-spam updates and manual actions have repeatedly hit gambling affiliate sites, and a link profile built on these methods is fragile — the links get discounted, and cleanup (audit, removals, disavow, reconsideration) costs far more than the rankings were worth.
The defensible link strategy in this vertical is narrow and slower: digital PR that earns editorial links through original data and expertise, link reclamation, genuine broken link building, and being a resource worth citing (original research, a substantive glossary, tested guides). Any outbound affiliate link must be marked rel="sponsored" so the site is not seen as selling ranking signals.
For affiliate-facing content, the framing is that manipulative link building no longer produces durable rankings and carries real penalty risk, that the only reliable approach is earning links by being genuinely useful and referenceable, and that a clean link profile plus strong own-domain content is what withstands link-spam enforcement and core updates.
Worked example
After a link-spam update reduces its rankings, an affiliate audits its backlinks, finds a paid guest-post network behind hundreds of referring domains, attempts removals, disavows those domains, and files a reconsideration request. Going forward it invests only in digital PR and reclamation, and marks all affiliate outbound links rel="sponsored".
Rankings recover over two quarters.
