Website Speed and Core Web Vitals Sprint

A faster site on mobile, with your Core Web Vitals problems found, fixed and measured before and after.

A slow mobile page can lose visitors before they read a word, and a failing Core Web Vitals report is hard to act on alone. This sprint finds what slows your Shopify, Webflow, Framer, HubSpot, Next.js or custom site and fixes it. We measure up to ten key pages, agree the fixes with you, make up to fifteen of them and measure again.

  • Field and lab data reviewed for your ten key pages
  • Up to fifteen fixes for images, fonts, scripts and apps
  • A before-and-after PageSpeed and Core Web Vitals report

What it is

Website Speed and Core Web Vitals Sprint is a one-time project for Shopify, Webflow, Framer, HubSpot, Next.js and custom sites. We review field and lab data for up to 10 key pages, agree a fix list, make up to 15 speed fixes and deliver a before-and-after PageSpeed Insights report. WordPress sites go to webcare24.

Why businesses buy it

Speed tools give you a score and a long list of warnings, but rarely say which fixes matter on your platform or how to make them safely. Hosted platforms add their own limits, and apps or tags pile up over time. This sprint starts from real visitor data and lab tests, then agrees a short, prioritized list with you. We fix images, fonts, scripts, apps and layout shifts without removing tools your business relies on. Every changed page is tested on mobile and desktop, and you get a before-and-after report rather than a promise.

Problems this solves

Pages feel slow on mobile and visitors leave early

We measure up to ten key pages from field and lab data, then fix what slows them most. Every changed page is re-tested on mobile and desktop.

Search Console flags Core Web Vitals issues nobody on the team understands

The fix list explains each problem in plain terms and ranks it with you. The written handover report shows how to keep watching Core Web Vitals after the sprint.

Apps, tags and scripts have piled up over the years

We clean up apps and defer scripts that are not needed straight away. Tools on your must-keep list stay in place.

Images and fonts load heavier than they need to, and pages jump

Image formats, lazy loading and font loading are among the up to fifteen fixes. Layout shifts are corrected so pages stop jumping as they load.

A good fit if

Your site runs on Shopify, Webflow, Framer, HubSpot, Next.js or custom code and feels slow on mobile.
Search Console shows Core Web Vitals problems you have not had time to work through.
Apps, tags and scripts have piled up, and you are not sure which ones cost the most speed.
You want a measured before-and-after record, not just another list of warnings.

Not the right fit if

Your site runs on WordPress. Speed work there is handled by webcare24, our WordPress care brand.
Your Shopify store is slow because it has outgrown its template. See Shopify Custom Theme.
Your search problems are redirects, indexing or canonicals rather than speed. See Technical SEO Fix Sprint.
Pages load fine but visitors still do not buy. See CRO Audit.

How it works

  1. You share website or code access, Search Console access and the apps, scripts and tags your business needs.
  2. We review field data and lab tests for up to ten key pages, on mobile and desktop.
  3. A prioritized fix list is agreed with you, ranked by the expected effect on each page.
  4. Up to fifteen fixes are made, such as image formats, lazy loading, font loading, script deferral and app clean-up, each approved before it goes live.
  5. Every changed page is re-tested on mobile and desktop, and you get a before-and-after PageSpeed Insights report.
  6. A written handover report explains the fix log and shows how to watch Core Web Vitals in Search Console.

What you provide within 72 hours

Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.

  • Website or code access by invite or a key you control.
  • Search Console access, shared by invite.
  • The list of apps, scripts and tags your business needs to keep.
  • One person who approves changes before they go live.
The 72-hour rule. Send everything on your checklist, including access, within 72 hours of ordering so your build starts on time.

Expected benefits and how to measure them

  • Can make key pages load faster on mobile
  • Helps Core Web Vitals move toward passing in Search Console
  • Gives your team a clear record of what changed
Largest Contentful Paint
Compare lab results in the before-and-after report, then field data in Search Console a month later.
Layout shift
Check the Cumulative Layout Shift figures in Search Console's Core Web Vitals report before and after.
Mobile engagement
Compare engagement rate on the key pages in analytics for the month before and after the sprint.

Before you start: Export Search Console's Core Web Vitals report and run PageSpeed Insights on your key pages before work starts.

These are things to track, not promised results. Outcomes depend on your data, your team and your market.

Running costs

There are no running costs. Fixes use your platform's own settings and code, so nothing new is billed each month. If a fix would need a paid app or service, we explain why first and only add it with your approval, from your own account.

Ask about running costs

Custom requirements

Add a note at checkout if you need something specific. If it fits within the Scope Card it is simply included. If it goes beyond it, you get a written Change Quote within two working days, and that work starts only once you accept it, with its time added to your delivery date.

Request a custom version

Keep it running

This is a one-time sprint, so there is no ongoing fee. New apps, tags and images slowly add weight again, so the Search Console walkthrough shows your team what to watch. If search visibility is the wider goal, SEO Essentials can keep an eye on site health each month.

Questions about this product

Can this sprint speed up a WordPress site?

No. WordPress speed and Core Web Vitals work is handled by webcare24, our WordPress care brand, because on WordPress the fixes depend on hosting, caching and plugin choices. This sprint is built for Shopify, Webflow, Framer, HubSpot, Next.js and custom-coded sites, where the fixes depend on each platform's own settings and code.

Will the speed sprint guarantee a passing Core Web Vitals score?

No. Nobody can honestly promise a score, because field data comes from real visitors and depends on their devices, networks and your content. The sprint fixes what slows your key pages most and shows the change in a before-and-after report. Search Console's field data then updates gradually over the following weeks.

What is the difference between field data and lab data for site speed?

Field data comes from real visitors using Chrome, collected over recent weeks, and is what Search Console reports as Core Web Vitals. Lab data comes from a single controlled test, such as PageSpeed Insights, and shows why a page is slow. The sprint uses both: field data to choose the pages and lab data to find the fixes.

Which speed fixes can you make on Shopify or Webflow?

Usually image formats and sizes, lazy loading, font loading, deferring scripts, removing unused apps and fixing layout shifts. Hosted platforms control their own servers, and hosting or server changes are outside the sprint on any platform. If the theme itself is the main cause, we tell you, and a rebuild is quoted separately.

Will you remove apps or tracking tags my business needs?

No. You list the apps, scripts and tags your business needs at intake, and those stay. We may suggest loading some later or removing ones nobody uses, but every change is approved by your named approver before it goes live. Removing tools your business relies on is never part of the fix list.

How is the speed sprint different from the Technical SEO Fix Sprint?

This sprint is only about speed and Core Web Vitals: images, fonts, scripts, apps and layout shifts. Technical SEO Fix Sprint covers crawl and indexing problems such as redirects, canonicals, sitemaps and robots.txt, with only speed basics. If Search Console shows both kinds of problem, the two sprints work well one after the other.

What happens if a speed fix breaks part of my site?

We undo or correct it. Every changed page is tested on mobile and desktop, and your approver signs off before changes go live, which keeps the risk low. If something still slips through, it is covered by 14 days of post-launch support, and the fix log shows exactly what changed and where.

What do I get at the end of the Core Web Vitals sprint?

A before-and-after PageSpeed Insights report for every changed page, a fix log of what was done and a written handover report. The handover report shows how to watch Core Web Vitals in Search Console. You also get 14 days of support for questions, and you can remove our access as soon as the sprint ends.
