SEO CHECKLIST FAQ

Auditing principles & methodology

Got questions? We have clear answers. If your question is not listed here, feel free to reach out directly.

We recommend a quarterly technical audit for active web applications, paired with instant pre-launch and post-deployment checklist verifications whenever releasing major design revamps, CMS migrations, or CMS route refactors. Crawlability, broken canonicals, and Core Web Vitals can decay rapidly during routine code updates.
