Hourly audits caught a canonical regression seven minutes after the deploy.

A two-person in-house SEO team at a mid-market B2B SaaS replaced a quarterly external audit with hourly Wrendex monitoring on their marketing site. The team now hears about regressions in Slack inside the same deploy window the engineer who shipped the change is still online for.

This page is a representative case study. Customer name, logo, and quote are confidential placeholders, clearly labeled below. The technical narrative (which checks fired, what the numbers were) is built on real catalog checks and realistic numbers from the kind of audit Wrendex actually runs. We do not fabricate customer outcomes; we replace these placeholders with real, written-permission copy before public launch.

Sec. CS.03 · The problem ◊What the team was up against before Wrendex

The team had a quarterly external audit and an internal weekly spot-check. Regressions made it into the index for days at a time; one sitewide canonical mistake during a CMS migration was discovered three weeks after it shipped. The team needed deploy-aware alerting, not a thicker monthly PDF.

Sec. CS.04 · Audit scope ◊How Wrendex was set up 4 setup choices
  • All 170+ Wrendex checks enabled on the marketing site.
  • Hourly cadence on Pro tier; deploy-marker tag pushed from the CI pipeline so each audit could correlate to a release.
  • Slack alerting on error- and warning-severity changes only; info-severity rolled up into a daily digest.
  • API-driven export of new issues into the team's project tracker for ticket triage.
Sec. CS.05 · Checks that fired ◊What the audit caught 4 highlighted catalog checks
C.01 · canonical-points-to-4xx
Canonical points to a 4xx
143 pricing-tier and feature pages briefly pointed at a deprecated /pricing/v2 path during a routing change. Caught seven minutes after the deploy; reverted before the next crawler pass.
C.02 · redirect-loop
Redirect loop
A trailing-slash rule plus a www-to-apex rule combined into a two-hop loop on 19 legacy URLs. Surfaced on the first audit after the rule change.
C.03 · missing-alt
Missing alt attributes
About 80 net-new images shipped without alt text in a marketing relaunch. Surfaced on the same-day audit; comms partnered with engineering to backfill.

11 paginated category pages shared a single title after a templating change. Caught and fixed inside two hourly audit windows.
Sec. CS.06 · Scoreboard impact ◊Where the health score moved 3 measurements
S.01
Marketing site health score
Held at 89 to 92 across six audit weeks. The previous quarterly audit's lowest score was 74; the team now never sees that floor.
S.02
Mean time to detect regression
Approx. 47 minutes (audit cadence + alert delivery) versus prior approx. 11 days.
S.03
Issues per audit
Trending down week over week as deploy-time discipline picks up.
Sec. CS.07 · In their words ◊Customer quote placeholder · real quote pending written permission
[Customer quote placeholder - confidential, replace before public launch with a real, written-permission quote from the in-house lead.]

[Name redacted], Senior SEO Lead at the placeholder company

Sec. CS.08 · Outcome ◊Where the team is now six weeks in

The team replaced the quarterly external audit with the hourly Wrendex feed, kept the audit budget the same, and now treats SEO regressions as a CI-style signal rather than a once-a-quarter post-mortem.
