SEO drift monitoring for agencies

The site changed. Traffic dropped. Prove it wasn't you.

Somebody ships a redesign, a plugin update, a "quick fix" — and your client's organic traffic pays for it. Driftwitness watches the SEO-critical elements on the sites you manage and hands you timestamped evidence of exactly what changed, when, and what it broke.

White-label evidence for agencies

Evidence your clients can't argue with.

When a client asks "what are we paying you for?" — send the report that answers it. Driftwitness produces client-ready, your-brand evidence of the SEO-critical changes on their site: what drifted, when, what you caught, and what it would have cost if you hadn't.

driftwitness — evidence ledger — example-client.com SIMULATED

Simulated data — illustrative only. This is the product doing its job on an example site.

The Monday-morning problem

Nobody tells the SEO what shipped on Friday.

Dev teams deploy. Plugins auto-update. CMS editors "tidy things up." In documented cases, site migrations have quietly wiped out around a quarter of organic traffic before anyone caught what changed. And when traffic drops, the question lands in your inbox:

from: client · mon 09:12
"Organic is down 30% since last week. What did you change?? We need answers before the board meeting Thursday."

So you burn a day diffing crawls, guessing at deploy dates, and writing a defense with no receipts. Driftwitness is the receipts.

What we watch

The changes that quietly kill rankings.

Not uptime. Not pixels. The SEO-critical elements — checked continuously, diffed semantically, and logged with timestamps you can put in front of a client.

TYPE 01

Title rewrites

A CMS "cleanup" rewrites your optimized titles. Caught, diffed, timestamped.

TYPE 02

Sneaky noindex

A staging flag ships to production and a money page vanishes from the index.

TYPE 03

Canonical changes

A canonical silently points your best page somewhere else.

TYPE 04

robots.txt lockouts

One new Disallow line walls off a section you spent a year ranking.

TYPE 05

Structured data loss

A template update drops the JSON-LD that powered your rich results.

TYPE 06

Orphaned pages

A nav redesign removes every internal link to a page that still "exists."

TYPE 07

Redirect regressions

A 301 flips to 302, a target changes, a chain appears. Equity leaks.

How it works

Three steps to a defensible record.

Add the sites you manage

No code changes, no tags, no access to the client's stack. Read-only monitoring of sites you're authorized to manage — baseline captured on day one.

We watch for drift

Continuous checks on every SEO-critical element, diffed semantically against baseline — and correlated with deploys, so "what changed" comes with "when it shipped."

You get evidence, not noise

A timestamped drift log, an alert within hours — and a white-label evidence report your client actually reads.

What we won't do
  • No alert storms. Query-param churn, rotating timestamps, A/B swaps, cookie noise — suppressed by design. If everything alerts, nothing does.
  • No black box. Every alert links to the exact before/after diff and the crawl that produced it.
  • No vanity metrics. We'll publish our false-positive methodology — and hold ourselves to it.
The deliverable

A report that proves your work — under your brand.

Every incident caught, every fix verified, every quiet week documented. Your logo, your domain, your client's name — our evidence engine. The monthly "what are we paying you for?" conversation, answered in advance.

Be first in line — and shape what we build.

We'll onboard a small group of agencies before public launch. Early-access members lock their launch price and get a direct line to the founders.

Questions

The short version.

Is this another uptime / visual-change monitor?

No. Uptime tools tell you the site is up. Visual tools tell you pixels moved. Driftwitness tells you the SEO-critical things changed — titles, indexability, canonicals, robots.txt, structured data, internal links, redirects — semantically diffed, deploy-correlated, and logged as client-ready evidence.

Do I need access to my client's codebase or CMS?

No. Monitoring is read-only and needs no tags, plugins, or code changes. You confirm you're authorized to monitor the sites you add.

What does "white-label evidence" mean?

Reports carry your agency's brand, not ours. But the point isn't the logo — it's what's inside: timestamped incidents, before/after diffs, catch latency, and quiet periods documented. Proof of work, not a dashboard screenshot.

When does it launch?

Early-access onboarding starts with a small group of agencies; the list is the only way in. We'd rather launch narrow and reliable than wide and noisy.
