SEO Sink vs Semrush
Semrush is the all-in-one SEO suite, and its Backlink Audit is the best-guided disavow workflow in the category: 45+ toxicity markers, a 0–100 score per link, one-click export. It is, start to finish, a report — an excellent one. Nothing in it touches the attack. While you review the spreadsheet, the farm's bots are re-crawling its links to confirm they're live. That loop is what we sink.
What SEO Sink does that Semrush doesn't
| SEO Sink | Semrush | |
|---|---|---|
| Sinks spam-link waves before they register in Google | ✓ core product | ✗ no |
| Forged-referer flood protection — your analytics stay human | ✓ sunk at the edge | ✗ no |
| Tarpit for hostile crawlers — starves the farm's verification loop | ✓ quicksand | ✗ no |
| Campaign attribution — which farm, first seen when, who else it hits | ✓ full graph | ✗ no |
| Enduring Network Protection — one tenant's attack is sunk for every tenant within the hour | ✓ within the hour | ✗ no |
| Parked & idle domain hijack watch (registry, DNS, content) | ✓ hourly | ✗ no |
| Human review of marginal links, niche-calibrated keep lists | ✓ approve / sink | ✗ no |
| Measured in public on a real 2,444-domain attacked estate | ✓ see the data | ✗ no |
| Built, reviewed & versioned disavow with evidence ledger | ✓ done-with-you — you upload; Google allows no vendor a way in | ~ exports a file — the rest is you |
| Works on any platform — one CNAME, no plugin | ✓ | ✗ n/a — reporting SaaS |
Where Semrush honestly wins
| SEO Sink | Semrush | |
|---|---|---|
| Keyword research, rank tracking, site audit, PPC data | ✗ not our product | ✓ full suite |
| Large third-party link index | ✗ we consume indexes, we don't sell one | ✓ |
| Guided toxicity scoring (45+ markers) | ✗ our verdicts come from the live attack graph | ✓ |
| Reporting breadth for agencies | ✗ | ✓ |
The one-line verdict
Semrush describes the wave beautifully and hands you the paperwork. SEO Sink sinks the wave, starves the farm that fired it, and tells you which farm it was.
If you need a full SEO suite, buy Semrush — genuinely. Then ask what the toxicity score does. A flagged link is still live, still pointing at you, still being verified by the farm every night. That's the gap we fill.
