Link exchanges and sponsored posts: what Google allows

Swapping articles and buying placements are normal marketing — until they are done to manipulate rankings. Here is where Google draws the line, in plain language.

What the rules say

Google's spam policies treat link schemes as spam: links meant to manipulate search rankings. The policy names, among others, buying or selling links that pass ranking credit, excessive link exchanges ("link to me and I'll link to you") and large-scale article or guest-posting campaigns with keyword-rich links.

What is allowed

Paid and exchanged placements are fine when the links are marked so they don't pass ranking credit:

• rel="sponsored" — for paid placements, sponsorships and anything exchanged for value.
• rel="nofollow" — when you don't want to vouch for the link.
• rel="ugc" — for user-generated content such as comments.

The article itself can still bring readers, brand recognition and mentions in AI answers — none of that depends on ranking credit.

Why direct swaps are the risky pattern

Two sites linking to each other over and over is the easiest scheme to detect. If you exchange articles, prefer circular exchanges (A writes about B, B about C, C about A), keep volumes low, write for readers, and label the links. That's the model behind the Satelo exchange: links are sponsored by default and articles are labelled as partner content.

Labelling for readers

Besides search engines, advertising laws require that sponsored content is recognisable to readers (for example the FTC rules in the US, and ad-marking rules in Russia). A short "Partner content" or "Sponsored" line at the top of the article is the simplest way to comply.

A safe checklist

• Paid or exchanged link → rel="sponsored".
• No exact-match keyword anchors at scale; use the brand or the URL.
• One mention, where it genuinely helps the reader.
• Few such articles per site per month.
• Never promise or buy "rankings".
