We're building the AI agent that ensures no SEO professional ever loses a backlink investment again.
Every year, SEO freelancers and agencies spend thousands of dollars acquiring backlinks — guest posts, niche edits, sponsored placements, and directory listings. But links don't last forever. Pages get deleted, sites get redesigned, sellers quietly remove links after cashing your payment, and anchors get swapped without notice.
Industry research consistently shows that a significant percentage of paid links disappear within a year. Most buyers never find out — because manually checking hundreds of URLs every day is work nobody wants to do.
Sentinel is your AI-powered backlink guardian. It works like having a tireless assistant who checks every single link you've paid for — every day, at 2 AM — and takes action the moment something goes wrong.
HTTP status, link presence, anchor text, rel attributes — every day.
Not just "link lost" — tells you exactly what happened and why.
Before/after screenshots for refund requests and client reports.
Polite, firm, or refund-request emails ready for your approval.
That's why Sentinel defaults to assisted mode — it drafts, you approve. Switch to autonomous only when you're ready.
Sentinel isn't an SEO suite. It's a specialist — monitoring, diagnosis, evidence, and recovery for the links you've already bought.
We never share your backlink data, seller contacts, or pricing with anyone. Row-level security ensures your data stays private.
Sentinel is designed specifically for SEO freelancers, consultants, and agencies who invest real money in backlinks. Whether you manage 25 links for your own site or 5,000 across multiple client domains, Sentinel scales with your portfolio.
