Website Testing
Website testing operated as six health pillars, not one Lighthouse run
QAble runs website QA as engineering practice: functional, performance, SEO, accessibility, security and cross-browser covered as one engagement, reported as one website posture.

The problem
Why website testing has to be its own discipline
Websites are tested in fragments: Lighthouse for performance, axe for accessibility, Postman for forms, Sitebulb for SEO. Each tool is right; the seams between them are where quality posture silently drifts.
Without structured website coverage
01
Lighthouse passes locally but Core Web Vitals slip in real-user metrics: lab data and field data tell different stories that the deploy pipeline never reconciles.
Performance gap02
SEO regressions ship silently: title, canonical, schema, or robots changes break ranking weeks before analytics surface the cause.
SEO drift03
Browser-specific bugs surface in production analytics rather than QA, because the test matrix runs on one engine and ships to three.
Cross-browser04
Accessibility lives in the marketing checklist but never in the release gate, and the audit finding lands later and costs more to fix retroactively.
A11y posture05
Forms, search, and conversion paths are tested once at launch and forgotten between releases, accumulating silent regressions across every deploy.
Regression riskThe QAble solution
Website testing done well treats the deploy pipeline as the gate. Functional, performance, SEO, accessibility, security and cross-browser pillars wired in upstream: regressions caught at PR or pre-deploy, not in real-user metrics three weeks later.
Six-pillar coverage
Functional, performance, SEO, accessibility, security and cross-browser covered as one engagement, not six separate tools.
Real-user signal validation
CrUX, RUM and field data alongside lab data: performance evidence that matches what real users experience.
Release-gated pillar checks
Website pillars wired into the deploy pipeline: regressions caught at PR or pre-deploy, not in production analytics.

Coverage areas
Website testing disciplines we deliver
Six disciplines applied as one website engagement, selected and combined depending on whether it is a health sprint, a pre-launch programme or continuous website QA.
01
Functional & UX testing
Charter-led functional and UX coverage: navigation, forms, search, content rendering, conversion paths, and the long-tail interactions content sites accumulate.

Methodology
The QAble website testing methodology
A six-stage rhythm that takes website QA from health audit to continuous posture, with documented evidence at every stage.
01
Health02
Test03
Run04
Triage05
Website06
ContinuousHealth audit
Baseline website health across the six pillars with risk and severity register.
Test plan
Design the test plan: automation suite, real-user signals, accessibility scripts, SEO checks and cross-browser matrix.
Run coverage
Execute coverage across all six pillars with Playwright, Lighthouse, axe, schema, security headers and assistive-tech runs.
Triage and gate
Triage findings against severity rubric, route to engineering and wire pillar checks into the deploy pipeline.
Website posture
Single website posture report: pillar-by-pillar status, regression trend and release readiness recommendation.
Continuous stewardship
Quarterly website QA review: refresh device matrix, retire stale checks and absorb new product surface and locales.
Health pillars
The QAble website health pillars
Six pillars, each with measurable evidence and a release gate. Coverage becomes engineering practice when website health is decomposed instead of averaged into a single tool score.

Risk patterns
Website testing mistakes a structured engagement removes
These are the patterns QAble replaces when taking over a website QA function. Each one quietly converts marketing investment into ranking, conversion or audit loss.
Critical01
Lighthouse-only performance
Performance validated only in lab: Lighthouse green, real-user metrics red. CrUX, RUM and field data tell a different story than the engineering branch ever sees.
Critical02
Silent SEO regressions
Title, canonical, robots, schema, or redirects changed during release with no QA gate: ranking drops show up in analytics weeks later, by which time the cause is hard to trace.
High03
Single-browser QA
Coverage runs on one browser engine: escapes show up disproportionately on Safari or WebKit, exactly the segments paid acquisition often lands on.
High04
A11y as marketing statement
Accessibility claimed in the website footer but never tested with real assistive technology: the audit finding lands later and is more expensive to fix retroactively.
Medium05
Third-party sprawl
Tag managers, marketing pixels, A/B tools and chat widgets accumulate over time: the resulting third-party impact is the largest single performance regression and is never owned.
Medium06
No continuous posture
Website tested at launch, never afterwards: every release ships with the assumption that what was good is still good, until analytics or audit say otherwise.

FAQ
Questions buyers actually ask.
Direct answers to the questions we get on the first advisor call.
How is website testing different from web application testing?
Both share functional, performance, accessibility and security pillars. Website QA puts more weight on SEO posture, Core Web Vitals as ranking signals, content rendering and cross-browser visual fidelity: the surfaces that determine traffic and conversion. Web application QA puts more weight on stateful workflows, API integration and authenticated session behaviour.
Do you cover Core Web Vitals as a release gate?
Yes. Core Web Vitals (LCP, INP, CLS) are gated against engineering targets in the deploy pipeline, with both lab data (Lighthouse, WebPageTest) and field data (CrUX, RUM) feeding the gate. Regressions surface at PR or pre-deploy, not in analytics three weeks later.
How do you validate technical SEO?
Technical SEO is a dedicated pillar. The audit covers robots, sitemap, canonical tags, meta, structured data (Schema.org), redirects, internal linking and pagination. Where appropriate, schema is validated through Google Rich Results test. Critical SEO checks are wired into the deploy pipeline so silent regressions are caught at the gate.
What about accessibility testing on websites?
Accessibility is a release-gated pillar aligned with WCAG 2.2. Coverage uses automated scans (axe-core, WAVE, Pa11y) for breadth and manual sessions with NVDA, VoiceOver and JAWS for depth. The accessibility release sign-off is part of every continuous engagement.
How do you decide which browsers and devices to cover?
The cross-browser matrix is built from your real audience analytics: browser, OS, device and screen-resolution distribution from your own GA, Mixpanel or RUM data. Coverage is sized to the segments that drive traffic and conversion, not assumed from market share.
How quickly can a website engagement begin?
Most website engagements begin within one week of scope agreement. The first few days build the pillar coverage map and audience matrix; active testing begins in the second week. For urgent launch windows, engagement can be accelerated with a focused kick-off scoped to the highest-risk pillars first.
