Google link spam policy
Google's link spam policy is the published section of its search spam policies defining link practices Google considers manipulative — buying or selling links for ranking purposes, excessive link exchanges, large-scale automated link building, and requiring links as a condition of an agreement.
Also called: link schemes, paid links, Google webmaster guidelines links
The policy's organizing idea is intent. It does not prohibit outreach, guest contributions, or PR; it prohibits arrangements whose primary purpose is to move rankings rather than to serve a reader. This is why two superficially identical guest articles can sit on opposite sides of the line depending on whether the placement was bought and whether the content exists for its audience.
Paid links are permitted so long as they do not pass ranking credit — the required disclosure is rel="sponsored" (rel="nofollow" is also accepted). The violation is not payment; it is payment for ranking credit without disclosure. Enforcement ranges from links being ignored, which is the usual outcome, to a manual action against a site, which is rarer and visible in Search Console.
For anyone running outreach at volume, the sentence that matters most is the one about scale: link building conducted through automated programs or services is named directly. The distinction that keeps a program on the right side is whether each contact is genuinely relevant and personal, or whether volume is doing the work.
Common questions
Is cold outreach for links against Google's guidelines?
No. Asking someone to consider linking to something genuinely useful is not a violation — Google's policies target buying links for ranking credit, link exchanges at scale, and automated large-scale link building. What matters is whether the outreach is relevant and the resulting link is an editorial choice.
Are guest posts against Google's link spam policy?
Guest posting is not banned. Google's policy targets guest articles published at scale primarily to obtain links, especially with keyword-rich anchors, rather than contributions written for a publication's actual audience. A single well-matched, genuinely useful contribution is not what the policy is aimed at.

Private blog network (PBN)
A private blog network is a group of websites created or bought by one owner for the purpose of linking to a target site. PBNs are a direct violation of Google's link spam policies.
Toxic backlink
A toxic backlink is a link from a site whose only apparent purpose is to manipulate search rankings — link farms, private blog networks, hacked pages, or directories with no editorial standard. The term is an SEO-industry label, not a Google classification.
Editorial link
An editorial link is a link someone chose to add because it was useful to their reader, with nothing given in exchange. It is the category of link search engines are trying to reward.
Guest posting
Guest posting is writing an article for someone else's publication, usually including a link back to your own site. It remains a legitimate tactic when the article is written for that publication's audience rather than produced primarily to place a link.
