Website Speed and Core Web Vitals

Slow sites are usually slow for specific, findable reasons: too many third-party scripts, unoptimized images, a page builder loading everything at once, or apps and plugins that were installed once and never removed.

I measure before I change anything, work through the actual causes, and measure again afterwards. I do not promise a particular score, because scores move with network conditions, traffic and the tools you have installed.

01 / Fit

Who I usually help

  1. 01Ecommerce stores where mobile pages feel slow to real customers
  2. 02Sites whose Core Web Vitals are failing in Search Console
  3. 03Stores carrying years of app or plugin buildup
  4. 04Businesses that want a clear explanation of what is slow and why

02 / Problems

What usually brings people here

  1. 01Largest Contentful Paint is slow because of hero images or render-blocking assets
  2. 02Layout shifts as fonts, banners and app widgets load
  3. 03Interaction delays caused by heavy JavaScript
  4. 04Page builders adding large CSS and JS payloads to every page
  5. 05Third-party tracking and chat scripts loading in the wrong order
  6. 06Unoptimized images and missing width/height attributes

03 / Scope

What I can do

  1. 01Core Web Vitals review using field and lab data, not just a single test run
  2. 02Shopify theme audits: script cleanup, app leftovers, section-level JavaScript
  3. 03WordPress audits: plugin load review, caching setup, theme and builder overhead
  4. 04JavaScript and CSS reduction, deferring and removing what is not used
  5. 05Image optimization, modern formats, responsive sizing and correct loading attributes
  6. 06App and plugin auditing with a recommendation on what can go
  7. 07Caching configuration and CDN/Cloudflare setup and tuning
  8. 08Database cleanup where it is genuinely part of the problem
  9. 09Mobile-specific performance work, since that is where most of the traffic is
  10. 10Before-and-after measurement so you can see what changed

04 / Process

A direct, careful process

  1. 01

    Measure first

    Current numbers on key templates, mobile and desktop, plus what field data exists.

  2. 02

    Find the causes

    A short written list of what is costing the most, in order.

  3. 03

    Fix in passes

    Biggest wins first, tested as I go, so a regression is easy to trace.

  4. 04

    Measure again

    Same templates, same conditions, so the comparison is honest.

Questions

Frequently asked questions

Can you guarantee a 90+ PageSpeed score?

No, and I would not trust anyone who does. Scores depend on your apps, tracking scripts and testing conditions. What I can do is remove the real bottlenecks and show you the before and after.

Will I lose features to make the site faster?

Sometimes there is a trade-off, usually around apps or third-party scripts. I will tell you what each one costs and let you decide.

Do you work on Shopify and WordPress performance?

Both, and the approach is similar even though the specifics differ.
