Strata
Surface 03 · Site Audit

A technical audit your engineers will actually merge.

Strata crawls your property from headless Chrome, grades every rendered URL across comprehensive checks, and produces a prioritized changeset ordered by traffic impact, not another PDF nobody opens.

How it works
START / 01
Headless-Chrome crawl

We render every page the way Google does, including JavaScript-generated content, lazy-loaded images, and hydration timing.

02
Impact-ranked output

Every issue carries an estimated traffic-delta. Your backlog is sorted by what moves the needle, not by what's easy to count.

03
Patches, not paragraphs

Fix suggestions come as code diffs your developers can paste into a PR. Where possible, we open the PR for you.

Changesets your team can actually ship

Each finding includes a fix, an owner suggestion, and an 'apply via PR' button when the change is mechanical (meta tags, canonical URLs, hreflang loops).

FAQ
How large a site can Strata audit?

We have customers on 14M-URL properties. Crawl completes in roughly eight hours for that scale, with streaming results as URLs finish.

Can I run an audit on staging?

Yes. Pass HTTP basic-auth or a header-based token in your crawl config. We never retain credentials beyond the crawl.

Do you support crawling behind a VPN or WAF?

Yes. Static egress IPs are available on Business and Enterprise.
