Fewer visitors giving up
Every second of waiting is a chance for someone to close the tab. A site that shows its main content quickly and responds to the first tap keeps more people moving toward the form, the call or the cart.

Website speed optimization and Core Web Vitals, measured before and after
Core Web Vitals work on sites you already own — measured before, measured after.
01 · Overview
Our website speed optimization service is for sites you already own that take too long to load. A slow site costs visits, sales and Google rankings, especially on phones over mobile data, which is where most of your traffic lives. We measure the real problem, fix it, and prove the difference with numbers.
The work centres on Core Web Vitals, the metrics Google uses to judge loading experience: LCP of 2.5 seconds or less, INP of 200 milliseconds or less, and CLS of 0.1 or less. We profile your site on real hardware, not just a lab score on fibre, and combine that with what your actual visitors experience in the field.
You get a prioritised list with the estimated cost and expected gain of each fix, so you can decide what is worth doing before we start. Then we do the work. It does not matter whether your site runs on WordPress, Shopify or custom code, or whether another agency built it. We work from San Juan with sites in Puerto Rico and beyond.
We profile the real thing on real hardware, not a lab score on fibre. Render-blocking resources, oversized images, layout shift, third-party scripts nobody remembers adding. You get a prioritised list with the cost and the expected gain of each fix, then we do the work.
What improving your Core Web Vitals does for your business
A signal Google actually measures
Core Web Vitals are part of the page experience signals Google considers. They do not replace good content, but a site that passes the thresholds stops carrying a handicap against faster competitors.
Decide with cost and gain in view
You do not get a generic list of a hundred warnings. Each fix comes with its estimated cost and expected improvement, ranked by priority, so you spend first where it pays most and park what will not move the needle.
Results you can verify
We measure before touching anything and measure again when we finish, with the same tools and conditions. The before/after Core Web Vitals report shows what changed and by how much, so you do not have to take our word for it.
How we optimise your website's performance
-
01
Field and lab audit
We review real-user data for your site and run tests on mid-tier devices over mobile connections. We pin down which pages fail, which metric fails, and the concrete cause behind each problem.
-
02
Prioritised list of fixes
Every issue we find comes with its estimated cost and expected gain, ranked by impact. You choose what we do. Scope and price are fixed before we start, with no hourly surprises.
-
03
Optimisation
We optimise images, fonts and assets, clean up the render path, remove or defer unnecessary third-party scripts, and fix layout shift. We configure caching and a CDN so the site responds quickly wherever your visitors are.
-
04
Final measurement and report
We measure again under the same conditions as the audit and hand over the before/after Core Web Vitals report, with recommendations so your team keeps the site fast as new content and features are added.
Who website speed optimization is for
- Sites failing Core Web Vitals in Search Console
- Online stores losing sales to a slow checkout
- WordPress sites weighed down by plugins and scripts
- Businesses with heavy traffic from phones on mobile data
- Teams that want a faster site without rebuilding it
What people ask about this service.
They are three Google metrics for real-world loading experience. LCP measures how long the main content takes to appear; good is 2.5 seconds or less. INP measures how quickly the page responds when someone taps or clicks; good is 200 milliseconds or less. CLS measures how much the layout shifts while loading; good is 0.1 or less.
Hosting is only one part. What slows most sites down happens in the visitor's browser: oversized images, heavy fonts, render-blocking resources and third-party scripts nobody remembers adding. A fast server cannot make up for a page that asks a phone to download and run too much before showing anything.
Yes, and that is the most common case for this service. We work on WordPress, Shopify, WooCommerce and custom-coded sites built by others. The audit tells us what can be fixed within the current platform. If the honest conclusion is that the site needs a rebuild, we tell you so, with the numbers in hand, before you spend money on patches.
It depends on the size of the site, the platform and what the audit finds. A contained problem, such as a Core Web Vitals failure, can often be handled in a two-week focused sprint at a flat price. For broader work we quote a fixed price after a scoping call. Either way, you know the full number before we begin.
No, and be wary of anyone who does. The lab score varies from run to run and is not what Google uses to judge real-world experience. Our goal is for your pages to pass the Core Web Vitals thresholds for real users. We show you the before-and-after measurements so you can see exactly what improved.
