Performance &Core Web Vitals
A site that takes 4 seconds to load loses 25% of visitors. Every second is money.
That's not a guess — it's Google's data. Another one: 53% of visitors abandon a site that takes longer than three seconds to load. Another: every 100ms improvement in speed increases conversions by 1%.
Performance isn't a "nice to have." It's Google, it's customers, it's money. We build fast sites. Green PageSpeed scores, metrics that meet every Google requirement, and load times under one second. No magic — a method.
01 / Why it matters
Why it matters
Performance moves four things you actually measure: rankings, conversions, mobile experience, and competitive position.
02 / The metrics
What are Core Web Vitals?
The three metrics Google actually measures. There are more (TTFB, FCP, TTI) — but these are the three that decide rankings.
03 / What we do
What we do
Optimization at every layer — from the browser to the database. Performance breaks everywhere, and we fix it everywhere.
04 / Tools

05 / How we work
How we work
- 01
Performance audit
We pull real data: PageSpeed, Lighthouse, and field data from Real User Monitoring. No guessing.
- 02
Prioritize by impact
Not every issue is equal. We start with the 20% of fixes that deliver 80% of the result.
- 03
Fix in code
Not a "plugin that fixes everything." Real fixes — code, images, queries, caching strategy.
- 04
Measure after every change
We don't estimate — we measure. Before and after, in a real user environment.
- 05
Continuous monitoring
Sites change. A new feature can slow everything down. We track performance over time and alert if something regresses.

FAQ
Frequently asked questions
Go to PageSpeed Insights and enter your URL. If the mobile score is below 90 — there's work to do. Below 50 — there's a lot of work to do.
LCP under 2.5 seconds. INP under 200ms. CLS under 0.1. All three green = you're fine. One red = you take a ranking penalty.
There is no honest flat price for performance work: the budget follows scope. The drivers are how much of the problem is in the hosting and caching layer versus the frontend code, how many templates share the same issues, and whether the fix is a targeted sprint or an architectural change. We scope the work first, then give a fixed, itemized quote — what is included, what is excluded and what would change the number. An audit with Lighthouse and real-user data comes first and the quote follows from it.
Quick wins (images, basic caching) — one week. Comprehensive optimization — 2 to 4 weeks. Architectural upgrade (SSR, edge) — 4 to 8 weeks.
Yes. WordPress can be fast with the right setup, but it has a ceiling. For maximum performance, custom development or Headless WordPress will give a better result.
Shopify is reasonably fast out of the box, but there's significant room to improve — mainly in the theme, third-party apps, and image optimization.
Yes. Core Web Vitals are an official ranking factor. They're not the only factor — content and links still matter more — but bad performance can bury a good site.
Continuous monitoring + CI/CD checks that test performance on every deployment. We implement this in your pipeline.
It's a separate but related domain. The same idea applies (App Start Time, Frame Rate, Memory Usage), and we handle it too.
Instead of a single origin server answering every request from one region — adding 100–300 ms for users on the other side of the country or the world — the response is served from the edge, physically close to the user. For a customer on the West Coast hitting an East Coast origin, that is a visible difference on every page.
Often yes. Unused libraries, plugins that load the whole system, chat widgets and analytics tools all running together — that's one of the main reasons sites are slow.
