Definition
Guest posting is publishing an article on someone else's website, typically in exchange for a byline and one or more links back to your own site. As a legitimate practice it is a form of content marketing and PR: contributing genuinely useful writing to a relevant publication reaches its audience, builds author and brand reputation, and can earn an editorially justified link.
As a manipulative practice — "guest posting at scale" with thin articles placed purely for links, often paid, on sites that accept anything — it is a link scheme that Google names explicitly and acts against.
The line between the two is drawn by intent, relevance and editorial standards: is the content something the host site's readers would value, is the host site topically relevant with real traffic and standards, is the link contextual and earned rather than the whole point, and would the placement exist if links carried no SEO value. Large-scale, low-relevance, paid-for guest posting fails all of these.
In context
iGaming is a niche where manipulative guest posting is rampant and heavily policed. Link vendors offer "gambling guest posts" on generic sites, on real sites' unmonitored sections, and on networks built for the purpose; buying these is exactly the pattern behind many unnatural-links manual actions in the sector.
The short-term ranking bump is real but fragile, and cleaning up after a penalty (audit, removals, disavow, reconsideration) costs far more than the links were worth.
The defensible version for an iGaming affiliate or operator is narrow and slower: contributing genuine expertise — regulatory analysis, market data, responsible-gambling perspective, industry commentary — to legitimate gambling-industry, marketing, sports or finance publications that have real editorial oversight, where the piece stands on its own and the link is incidental. This overlaps with digital PR.
Practical safeguards: treat any offer priced per link or promising a number of placements as a scheme; check the host site for real traffic, editorial standards and topical fit; keep anchor text natural and mostly branded; disclose paid relationships where required; and diversify so the link profile is not dominated by guest-post links. If a placement would only be worth doing for the link, it is not worth doing.
Worked example
An affiliate declines a vendor package of 20 "gambling guest posts" at a fixed per-link price. Instead its head of compliance writes an analysis of new advertising rules for a recognised iGaming trade publication; the piece is edited, published on merit, and links once to the affiliate's regulation guide.
It is one link, but an editorial one that will not trigger a manual action.
