Built by the people it happened to.

The estate that forced us to build it

SEO Sink wasn't a market-gap whiteboard exercise. We operate a 2,444-domain betting-affiliate estate — one of the most competitive, most-attacked verticals in search, where the difference between rank 3 and rank 9 is measured in tens of thousands of dollars a month per keyword. In October 2025 that estate came under industrial negative-SEO attack: churn-farm link waves, forged-referer floods, botnet verification loops, and anchor text designed to make the spam look self-inflicted. While fighting it, we swept our own domains and found 56 of them serving third-party scam redirects — hijacked through dangling DNS, invisibly, for months. Nobody knew. Nobody was watching.

So we built the watcher, then the sink, then the attack graph. The numbers the machinery produced are public, because we publish them: 57,302 verified hostile domains on The Attack Graph, ~48,000 forged-referer hits a month across 10 sites, 2,842 botnet challenges a day from a single cloud-hosted botnet, 352,571 hits sunk in the first week live. All of it, honestly labelled, on the real attacks page.

Who's behind it

The operator side of the team has been in online betting affiliate marketing since the early days — online poker around 2000, the first online bookmakers before that, affiliate programs ever since. Two decades of watching this industry attack itself is why the product looks the way it does: we didn't learn negative SEO from blog posts. It cost us money, then it taught us its playbook. (One more symmetry we couldn't have invented: seosink.com itself is an aged domain whose past life was an SEO backlink service. The name used to be what it sinks — Google's index remembers, the farm's graph remembers, and we're the rehabilitation case study either way.)

What we believe

• Honesty is the differentiator. We publish our own attack data two-sided — including the properties still declining. Where a competitor is genuinely the better tool (backups, cleanup, full SEO suites), we say so and link it.
• Measured in public. "Median hours from first hostile signal anywhere in the network to protection everywhere" is a number we expose, not a slogan.
• No absolutes. Verdicts are observed evidence at a point in time, never "you're 100% safe". Anyone selling certainty in this space is selling fiction.
• Humans on the marginal calls. Clear spam sinks automatically; anything ambiguous gets reviewed by us, with our recommendation — approve or sink stays with you.
• Condemned, not disseminated. What we sink is identified, attributed and abuse-reported — not quietly redirected to become someone else's problem. Why the name works that way.

What we make

One product: proactive negative-SEO and hostile-bot defence at the edge — one CNAME, no plugin, any platform. Live sites, parked domains, whole estates. It starts free: the 10-second check that found our own 56 hijacked domains. If it flags something, you'll hear what it means from a human.
