Paid Guest Posts: What Google, Bing, YouTube and the FTC Actually Require

Four Rulebooks, Four Different Questions

Buying a guest post feels like one transaction, but it is judged four times. Search engines ask whether the link was paid for and whether it says so. Google also asks whether the article belongs on the site that hosts it. Video platforms ask whether the sponsorship was declared. And consumer-protection regulators such as the US Federal Trade Commission ask whether readers were told. A placement can pass one test and fail another, so it helps to read each rule as written rather than as it is retold in sales pitches.

Google: Paying Is Allowed, Passing Ranking Credit Is Not

Google's spam policies do not forbid sponsored content. What they list as link spam is "advertorials or native advertising where payment is received for articles that include links that pass ranking credit", together with optimized anchor text placed in articles and guest posts on other sites. Payment is read broadly: the same list includes "exchanging goods or services for links" and sending someone a product in exchange for a write-up that includes a link.

The way out is a link attribute. Google introduced rel="sponsored" in September 2019 for links that are part of advertisements or paid partnerships, alongside rel="ugc" for user-generated content. From 1 March 2020 it began treating nofollow, sponsored and ugc as hints about which links to crawl and how to weight them, rather than as strict commands. Its current documentation tells site owners to mark advertisements and paid placements with sponsored.

In practice that means two things for a buyer. First, a paid link that is correctly marked is within the rules, but it should not be expected to pass ranking credit; what you are buying is the audience and the association. Second, a seller who promises a "dofollow" paid link is promising something Google's policy treats as spam, and the risk of that falls on both sites.

Google's Second Rule: The Host Has to Make Sense

A link attribute does not fix a placement that does not belong. Google's site reputation abuse policy targets third-party pages published on a strong site chiefly to borrow its ranking signals. In Google's words, "the goal of this tactic is for the content to rank better than it could otherwise on its own". Its examples are pointed: sponsored payday-loan reviews on an educational site, and a low-quality "best casinos" page on a medical site.

The same policy lists what is not abuse, and the list matters to guest post buyers. It includes "columns, opinion pieces, articles, and other work of an editorial nature", and advertorial or native-advertising pages "where the purpose is to share content directly to readers". In November 2024 Google added that first-party involvement or oversight does not by itself exempt third-party content published to exploit a site's signals. So the test is purpose and fit, not who pressed publish: an article written for that publisher's readers, on that publisher's subject, is in the safe group.

Bing: No Safe Harbour Written Down

Bing's Webmaster Guidelines treat bought links as manipulation without qualification. They name link buying alongside link spamming, private networks and fake social promotion, and say links "should be earned organically". The consequences listed run from lower rankings and lost eligibility for Copilot grounding to removal from the Bing index.

What the guidelines do not contain is Google's escape route. The page we read on 9 October 2026 does not mention nofollow or sponsored at all. That is not evidence that Bing penalises a correctly marked paid link, but it does mean there is no written assurance that marking it is enough. Bing's results also feed other products, from partner search engines to AI assistants, so its silence is worth taking seriously.

YouTube: The Placement Is the Video

On YouTube there is no article to place; the paid product is a creator's video. YouTube requires creators to use its paid promotion declaration for any content influenced by a brand in return for something of value, shows viewers a disclosure label, and can remove or age-restrict undeclared promotions or affect the channel's monetization. Some categories cannot be promoted at all, from weapons to essay-writing services, and others, such as gambling and financial services, are restricted.

The link side is weaker than many buyers assume. In Shorts, URLs in descriptions and comments are not clickable, and long-form descriptions only carry clickable links once the channel has advanced features. If a sponsorship pitch is built around "the link in the description", check which format the video will be.

The FTC: Disclosure Is for People, Not Crawlers

A sponsored attribute is invisible to readers, and that is where the FTC comes in. Its endorsement guidance says a disclosure is needed when there is a connection between the endorser and the brand that a significant minority of consumers would not expect. The disclosure has to be clear and conspicuous, placed where people will not miss it rather than buried in a description box, a comment or behind a link. Bloggers paid or given products must disclose it in each post, because readers may land on any single post on its own. The FTC's own suggested wording is as short as "#ad".

The FTC regulates the US market, and other countries have their own advertising rules. The common ground is simple: a reader who reaches the article from anywhere should be able to see that it was paid for.

Three Seller Claims, Checked Against the Rules

"Our links are dofollow, that is what you are paying for." Google's spam policies describe paid links that pass ranking credit as link spam, and warn that sites which violate the policies "may rank lower in results or not appear in results at all". A seller advertising the absence of a sponsored attribute is advertising the violation, and the risk is shared by the site you are trying to promote.

"A nofollow link is worthless." Not quite. Since March 2020 Google has treated nofollow and sponsored as hints about how to weight links rather than as blanket instructions to ignore them. More to the point, a placement on the right publisher is read by that publisher's audience whatever its link attribute says. Pay for the audience and the association; do not pay for ranking credit you are not entitled to.

"Google can't tell that a post was sponsored." No one outside Google can promise that. Google says it detects violations "both through automated systems and, as needed, human review that can result in a manual action". A placement that only works if nobody looks closely is a poor long-term buy.

The Four Rules Side by Side

A Buying Routine That Satisfies All Four

1. Agree the link attribute in writing before you pay: sponsored for a paid placement. If the seller refuses, you have learned what you are buying.
2. Agree a visible label. "Sponsored" or "Paid partnership" at the top of the article covers the reader, which the link attribute does not.
3. Keep anchor text descriptive, not engineered. Your brand name or the page title reads naturally; an exact-match money keyword is what the spam policy describes.
4. Buy on topic. Choose a publisher whose recent articles your piece would sit among comfortably. Our category hubs group publishers by subject for this reason.
5. Treat free products as payment. A review copy or free service in exchange for a linked write-up is covered by the same rules as cash.
6. For video, ask for the declaration. Confirm the creator will use YouTube's paid promotion setting and say it out loud in the video.
7. Keep the paperwork. Save the brief, the agreed attribute and the published URL, so you can show what was agreed if a question comes up later.
