Evidence first. Fixes next.

One crawl. Twelve views of launch readiness.

Search visibility is only one part of a launch. LaunchChecker reads the technical, distribution, trust and conversion signals that decide whether people can find your product—and whether the experience works when they do.

See what a finding looks like

SEO

Indexability, canonicals, sitemap coverage, redirects and broken links.

AEO

AI crawler access, server-rendered content and answer-ready structure.

Metadata

Unique titles, descriptions, robots directives and page-level signals.

Social

Open Graph images, Twitter cards, image reachability and favicons.

Structured data

JSON-LD types, required fields and markup that search engines can read.

Compliance

Privacy, imprint, consent ordering, external fonts and regional pages.

Email

SPF, DKIM, DMARC and MX records that determine whether mail arrives.

Security

TLS, HSTS, CSP, cookie flags, mixed content and exposed dependencies.

Accessibility

Alt text, labels, headings, zoom behaviour and accessibility statements.

Performance

Compression, document weight, render blockers and oversized assets.

Conversion

Contact routes, signup paths, analytics, pricing clarity and trust cues.

Technical basics

HTTPS, certificates, host coverage, 404 behaviour and response health.

Every result is tied to evidence from the live site. Checks that cannot be measured are marked as skipped, never guessed.

Check my site

A report that gets you to the fix.

Each finding shows what was detected, why it matters and the implementation path for your stack. The example is illustrative; your report is generated from your site.
