Website Speed & Core Web Vitals Services That Actually Pass

A 100 score in PageSpeed Insights is not the goal. Passing Core Web Vitals on real user data is. We fix the LCP, INP, CLS, and TTFB problems in Google’s field data, so your pages load faster for real visitors, rank higher, and convert more, on WordPress, Shopify, and custom sites alike.

Ranking

Core Web Vitals is a confirmed Google ranking signal tied to real user experience.

What Are Core Web Vitals?

Core Web Vitals are Google’s set of metrics for measuring the real speed and stability that people experience on your site. Every Chrome browser records how fast each page loads, how quickly it responds to a tap or click, and whether the layout jumps around while loading, then reports that back to Google. That real-visitor dataset, the Chrome User Experience Report, is what Google uses to judge your site, and it is a confirmed ranking factor.

There are three Core Web Vitals: Largest Contentful Paint (load speed), Interaction to Next Paint (responsiveness), and Cumulative Layout Shift (visual stability). Time to First Byte sits underneath all of them as the server-response foundation. To pass, at least 75% of your real visitors need a “good” score on each. We optimize all of them, and we optimize for the data Google actually uses.

LCP

Largest Contentful Paint — load speed

How long until the largest visible element, usually a hero image or heading, finishes loading. This is how fast the page feels to arrive.

INP

Interaction to Next Paint — responsiveness
How quickly the page responds visually when a visitor clicks, taps, or types. It replaced First Input Delay as the interactivity metric.

CLS

Cumulative Layout Shift — visual stability
How much the layout moves unexpectedly while loading, like a button jumping just as you go to tap it. It is a computed score, not a time.

TTFB

Time to First Byte — server response
How quickly your server starts responding. It is not a Core Web Vital itself, but a slow TTFB drags down LCP and every other metric.

A 100 PageSpeed Score Is Not a Core Web Vitals Pass

You can score 100 in PageSpeed Insights and still fail Core Web Vitals. The score is a lab test on one simulated load. The pass or fail comes from field data: your real visitors, on their real devices and connections.

Field Data (what we optimize)

Real visitors, from Google’s CrUX report

Lab Data (the score most chase)

One simulated load, from PageSpeed / Lighthouse
Some providers guarantee a 100 score by only partially loading the page until a user interacts, which cheats the test and can make the site slower and harder for Google to crawl. We do not chase the score. We fix the real bottlenecks so your field data passes and stays passing.

Our Website Speed & Core Web Vitals Services

Every engagement starts with your real field data, then works down the stack, from your server to your scripts, fixing what actually moves the metrics.

Core Web Vitals Audit

A full audit using Search Console, CrUX field data, and lab tests to pinpoint exactly which LCP, INP, CLS, and TTFB issues are failing your real visitors.

Largest Contentful Paint (LCP)

We fix slow hero images, render-blocking CSS and JavaScript, slow fonts, and lazy-loaded above-the-fold content so your main element appears fast.

Interaction to Next Paint (INP)

We break up long JavaScript tasks, defer third-party scripts, and reduce main-thread work so your site responds instantly to taps and clicks.

Cumulative Layout Shift (CLS)

We reserve space for images, ads, and embeds, fix font-swap jumps, and stop late-loading elements from pushing your content around.

TTFB & Server Response

We tune caching, edge and CDN routing, database queries, and hosting so your server responds fast, the foundation every other metric depends on.

Image & Asset Optimization

Modern formats, correct sizing, compression, lazy loading below the fold, and preloading key assets to cut page weight without losing quality.

Code, CSS & Script Cleanup

We remove unused CSS and JavaScript, defer and minify assets, and tame heavy third-party scripts like chat widgets, trackers, and video embeds.

Monitoring & Regression Watch

Field data takes weeks to update, so we track it after each fix and watch for regressions from new plugins, themes, or content that slow you back down.

Deliverables You Can Actually Use

No vanity dashboard. Every speed engagement produces work your team and your developers can act on and verify.

The Speed Problems We Solve

If any of these sound familiar, your field data is likely failing even if a tool says your speed is “fine”.

How We Get Your Site Passing

A clear, low-risk process. We plan and discuss risky changes before we make them, and we verify against field data, not just a score.

Measure Real Speed

We pull your CrUX field data, Search Console Core Web Vitals report, and lab tests to see how real visitors experience your site and which metric is actually failing.

Diagnose the Bottlenecks

We trace each failing metric to its real cause: a heavy image, a blocking script, a slow server, or a shifting layout, and rank the fixes by impact and risk.

Fix, Safely

We take a full backup, test risky changes on staging where needed, and implement incrementally so nothing breaks. We agree on a rollback plan for any higher-risk change in advance.

Validate the Fix

We re-test in the lab immediately, then watch the field data over the 28-day window to confirm your real visitors are now passing, not just a single test.

Monitor & Maintain

Speed is not set-and-forget. New plugins, themes, and content can slow you back down, so we keep tracking field data and flag regressions before they cost rankings.

The situation

The store passed Lighthouse on desktop but failed Core Web Vitals on mobile field data. Heavy hero images, a bloated page builder, and a slow shared host were dragging every metric down for real visitors.

What we did

Results vary by platform, theme, hosting, and starting speed. Core Web Vitals field data takes up to 28 days to fully reflect a fix in Google’s report.

Why Businesses Choose Us for Speed

We fix field data, not scores

We optimize the real-visitor data Google uses to rank you, so your pass sticks instead of evaporating the moment a real user loads the page.

No broken layouts

We back up first, test risky changes on staging, and keep your design and functionality intact. Faster should never mean broken.

Any platform

WordPress, WooCommerce, Shopify, or custom, we work down the whole stack from hosting and caching to code and images, not just plugin toggles.

SEO, dev, and hosting in one team

Speed is a technical SEO problem. We build sites, host them on tuned servers, and do the SEO, so fixes do not stall across three vendors.

Website Speed & Core Web Vitals: Your Questions Answered

What are Core Web Vitals?

Core Web Vitals are Google’s three metrics for real user experience: Largest Contentful Paint (load speed, good is under 2.5 seconds), Interaction to Next Paint (responsiveness, good is under 200 milliseconds), and Cumulative Layout Shift (visual stability, good is under 0.1). To pass, at least 75% of your real visitors need a good score on each. They are collected from real Chrome users and are a confirmed Google ranking factor.

Because they measure different things. A PageSpeed or Lighthouse score is lab data: one simulated load on a test device. Core Web Vitals pass or fail on field data: your real visitors, on their real devices and connections, collected over 28 days. It is entirely possible to score 100 in the lab and fail the field data your visitors actually experience, which is the data Google ranks on.
Yes. Core Web Vitals is a confirmed Google ranking signal, and a slow site also hurts you indirectly: more than half of mobile visitors abandon a page that takes over three seconds, which lowers engagement and conversions. Speed affects rankings, user experience, ad quality scores, and revenue at the same time.
The fixes themselves are usually implemented within days to a few weeks depending on scope. Lab scores improve immediately, but Core Web Vitals field data takes up to 28 days to fully update in Google’s report, because it is a rolling 28-day average of real visitors. We verify against that field data, not just the instant lab result.
No. We take a full backup first, test any higher-risk change on a staging copy, and make incremental changes with a rollback plan agreed in advance. Our goal is a faster site that looks and works exactly like it did before, just without the elements that were slowing it down.
No. WordPress and WooCommerce are common, but we also optimize Shopify, custom, and headless sites. The metrics and the approach are the same across platforms: measure real field data, find the true bottleneck, fix it at the right layer, and verify. The specific tools change, the method does not.
Time to First Byte is how quickly your server starts responding to a request. It is not a Core Web Vital by itself, but it is the foundation under all of them: a slow TTFB delays Largest Contentful Paint and everything after it, and a slow response to Google’s crawlers can hurt indexing too. A good TTFB is under 0.8 seconds, and we tune hosting, caching, and CDN routing to get there.
Speed helps indirectly. AI Overviews and answer engines favor pages they can crawl and parse quickly and reliably. A fast, stable page with a healthy TTFB is easier for both search engines and AI systems to fetch and process, so the same speed work that helps you rank also supports your visibility in AI-generated answers.
A one-time speed audit typically runs a few hundred to around fifteen hundred dollars, and audit-plus-implementation is usually a few thousand depending on your platform and how many templates need work. Ongoing monitoring retainers start lower and scale with site size. We give you a fixed quote after the free audit, based on your actual site.
