Situation

WordPress site with degraded performance, inconsistent SEO configuration, and risk from plugin sprawl and scattered settings.

Task

Find root causes of slowness/errors, clean technical SEO, and propose a realistic phased improvement plan without breaking production.

Action

1) Audit with Query Monitor: timings, queries, hooks, conflicts. 2) Plugin review: redundancy, impact, alternatives, and safe removal. 3) Recommended cache tuning (server + WP) and asset handling (selective minification). 4) Technical SEO review: robots.txt, sitemap, canonicals, indexation, thin pages. 5) Hardening: permissions, exposed endpoints, updates, and best practices.

Outcome

Average TTFB 1.2s -> 520ms
Home CLS 0.18 -> 0.06 after fixing images and fonts
Recurring 404/500 down -70% after cleaning plugins/routes
Indexable coverage stabilized after cleaning sitemap/robots

Summary

Technical WordPress audit focused on performance, security, and technical SEO.
