Trust and engineering hygiene
Website best practices test for modern baseline quality
Best practices sound abstract until they become incidents—mixed content warnings, outdated libraries, or missing HTTPS. This test surfaces engineering hygiene issues that often sit upstream of performance and SEO work.

What “best practices” includes here
In Lighthouse terminology, best practices focus on security and correctness signals that reduce risk and prevent subtle breakage as browsers evolve.
- HTTPS usage and avoidable mixed content patterns when detectable.
- Console error signals that may indicate broken scripts or resources.
- Browser feature usage that may be deprecated or risky.
- General quality checks that do not fit strictly under performance or accessibility.
Why baseline quality is a business topic
Trust erodes quickly when browsers show security warnings, console errors flood developer tools, or third-party scripts fail silently. Many of these issues are inexpensive to prevent once you can see them in one place.
If you are improving performance, best-practices fixes often unlock safer caching and script loading strategies. See also our dedicated performance and SEO tests for adjacent signals.

Website best practices test FAQ
Is this a security audit?
No. It surfaces common automated signals, not penetration testing or threat modeling. Treat results as a hygiene checklist.
Why might my score differ between environments?
Staging sites, password protection, or different CDN rules change what the lab can fetch. Test the public URL customers actually use.
Do third-party scripts affect the score?
Yes. Tags for analytics, chat, ads, or A/B testing can introduce warnings. The report helps you decide which partners are worth the tradeoff.
How often should I re-run?
After releases that touch templates, dependencies, or global headers—monthly for stable sites, weekly for active product teams.
