Continuous monitoring
Your site won't wait for its next audit to break.
A deploy, a DNS change, a lapsed certificate, a competitor winning your AI answer — these happen between scans. SEOLZ keeps watching after the scan is done, and tells you the moment something changes for the worse. It's not an uptime monitor — it watches whether your site still works, ranks, converts and gets cited, not just whether the server responds.
Most days it's quiet — that's the point. You hear from it when something moves.
Find. Fix. Watch.
An audit is a photograph — true the second it's taken, stale by the next deploy. SEOLZ is the third step most tools skip: it keeps watching, so the work you did to fix your site stays fixed, and anything new that breaks surfaces while it's still cheap to fix.
Find
One pass across six surfaces — SEO, accessibility, security, AI visibility, tracking and site health — resolved into one prioritized list.
Fix
Every finding comes with platform-specific, paste-ready steps for your CMS, cart and plugins. Not a list — a plan.
Watch
Then it doesn't stop. Between scans, SEOLZ re-checks the fragile, revenue-critical things and alerts you the moment one regresses.
What we watch, between every scan.
Five surfaces where a silent regression costs you customers, rankings, citations — or draws a demand letter. One place tells you the moment any of them moves.
Accessibility
We re-drive your critical flows by keyboard — not just scan the markup.
- ✓A keyboard trap or lost focus that appears on checkout, login, cart, search or contact
- ✓Interaction failures a static scanner can't see — the kind ADA complaints are built on
Security
The posture that protects your visitors and your brand's email — watched for drift.
- ✓A security header (HSTS, CSP…) that disappears after a deploy
- ✓A component with a known CVE loaded on your pages
- ✓A subdomain pointing at a dead third-party service an attacker could hijack
- ✓A certificate issued for your domain by a CA you don't use
- ✓SPF/DMARC weakened, TLS downgraded, or HTTPS broken
AI visibility
Whether the AI answer still names you — or started naming a rival.
- ✓You drop out of an AI answer you used to win
- ✓A competitor is cited in your place, per engine
Findability (SEO)
New structural problems that quietly cost you rankings and citations.
- ✓A new critical issue — duplicate titles, missing canonicals, broken structured data
- ✓Ranked by the pages and traffic actually affected
Site health
The lifecycle basics that take a site fully offline when they lapse.
- ✓An SSL certificate or domain registration approaching expiry
- ✓Insecure (mixed) content, or an end-of-life server
The checks, spelled out.
Not a vibe — a list. Each check we run between scans, its cadence, and exactly what trips an alert.

The things only SEOLZ can tell you.
Uptime pingers watch if your site is up. Overlays claim to watch accessibility. Neither catches these — because they read markup, not behaviour, and they watch one thing, not the whole surface.
- ✓We re-drive your checkout by keyboard and tell you the moment it breaks — overlays and static scanners can't.
- ✓We name the components on your pages that carry known CVEs, and the version to update to.
- ✓We flag a subdomain that's become hijackable before an attacker finds it.
- ✓We watch certificate-transparency logs and warn you when a cert appears for your domain that you didn't request.
- ✓We tell you when a competitor takes an AI answer you used to hold — and which engine.
- ✓And when several of these move in the same window, we connect them: one deploy, three regressions.
One feed, not five tools
Ranked by what it's costing you — not by alphabetical severity.
Everything that changes lands in one activity feed, ordered by likely impact: how severe it is, how many pages it hits, and — when Search Console is connected — the traffic riding on it. The checkout regression on the page a fifth of your revenue flows through rises to the top; the cosmetic warning sinks.
And you get oneconsolidated alert when things change — not one email per subsystem. Most days there's nothing to send. That silence is the product working.
- ✓A single activity view across all five surfaces, impact-ranked
- ✓Each item: what changed, what it affects, and the one thing to do about it
- ✓Resolutions tracked — see it caught, and see it fixed
- ✓One digest, deduplicated, so a busy day can't bury the signal
- ✓A per-domain health read at a glance: what's clear, what needs attention
When three things break at once, we tell you it was one deploy.
We can't see your deploys — but we can see when your accessibility, security and structure all moved in the same window. SEOLZ groups them into a single incident so you chase one root cause, not three separate fires. That connection is something no single-purpose monitor can make.
Find it. Fix it. Then never wonder if it broke again.
