Definition
A link exchange, in the Russian SEO tradition often a formal "биржа ссылок", is a marketplace that brokers the buying and selling of backlinks - the advertiser pays, the platform places a link on a participating site, and money and link inventory change hands at scale. Historically these operated on a rental model (pay monthly to keep the link live) or a one-off placement fee, with pricing driven by the donor site's metrics.
Paid link schemes of this kind are a direct violation of Google's and Yandex's link-spam policies. Both search engines have spent years building automated detection for the footprints these marketplaces leave - patterned anchor text, links from sites that sell links, unnatural link velocity, irrelevant donor-target pairings - and links identified this way are neutralised at best and a ranking-suppression trigger at worst.
In context
iGaming is one of the most aggressively link-spammed verticals, and link exchanges are a large part of how that spam is produced. The short-term appeal is obvious - rank a casino affiliate site quickly in a competitive niche - but the risk profile is bad: gambling sites are scrutinised more closely, the marketplaces themselves are known to search engines, and a manual action or algorithmic suppression on a site built this way can wipe out the traffic that the whole business depends on, with a slow and uncertain recovery.
The durable alternative is earned and editorially-placed links: original data and research that industry media cite, genuine partnerships and sponsorships, expert commentary, tools and datasets worth referencing, and digital-PR outreach that pitches something a journalist actually wants. These are slower and more expensive per link but they are defensible, they compound, and they do not carry a latent penalty.
Where paid placements are used at all, the defensible version is treating them as advertising - rel="sponsored" or rel="nofollow" on the link, chosen for referral traffic and brand exposure rather than for passing ranking signal.
Worked example
An affiliate buys 300 rented links through an exchange to push a new casino section. Rankings rise for two months, then fall sharply after a spam-update refresh flags the link pattern.
Recovery requires disavowing the bought links and rebuilding authority through earned coverage over the following year - far more total cost than the earned approach would have been.
