Implementation-first service

WordPress cold TTFB spikes with WP Rocket, Cloudways, cache, or CDN issues

For WordPress sites where cached pages feel fast but first hits, uncached URLs, product/category pages, or key landing pages spike into multi-second TTFB.

Sprint shape

Clear scope before implementation, one controlled sprint, and written verification at the end.

The first pass is meant to move the actual problem, not generate vague theory or generic audits without implementation.

Typical issues

  • Cache misses on important landing pages.
  • Fragmented cache by query string, language, cookie, or user agent.
  • WP Rocket preload not warming key pages.
  • Varnish, WP Rocket, Cloudways, or CDN behavior fighting each other.
  • Plugin invalidation clearing cache too aggressively.
  • Heavy uncached dynamic render on first request.
  • Server cron, preload, or origin resource issue.

Sharper symptoms

Start with the exact failure if it already has a name.

These narrower pages map the same service lane to a more specific failure path, input set, and first-sprint shape.

Core Web Vitals heavy JavaScript ecommerce

When ecommerce product or category pages are slowed by third-party scripts, GTM overhead, widgets, long tasks, and template code.

What I check first

  • Cold versus warm TTFB on representative URLs.
  • WP Rocket, Cloudways, Varnish, CDN, and Cloudflare settings that affect cache eligibility.
  • Headers and cache status across repeat requests.
  • Plugins, parameters, cookies, language rules, or preload gaps that fragment the cache.

What the first sprint includes

  • Baseline cold and warm TTFB checks.
  • Cache miss isolation across important templates.
  • Safe first-pass fixes in cache, preload, plugin, or CDN settings where access allows.
  • Repeated cold and warm verification plus a written handoff.

What I need from you

  • One or more slow URLs and one fast comparison URL.
  • Hosting, cache plugin, CDN, and Cloudflare status.
  • Recent plugin, theme, cache, DNS, hosting, or CDN changes.
  • Access level for WordPress admin, hosting panel, CDN, and Cloudflare if available.

Pricing expectation

Most WordPress TTFB/cache sprints land between $850 and $1,500 depending on stack complexity and verification window.

What you get

A WordPress cache-path sprint that separates cold and warm behavior, identifies why important pages miss cache, applies safe first-pass fixes, verifies repeated runs, and documents the remaining risk.

Best fit

Best fit when the stack is specific enough to test: WordPress, hosting, WP Rocket or similar cache layer, CDN or Cloudflare, and a short list of representative URLs.
