LCP: main content render speed
How many seconds until the page's largest element (hero image or headline) becomes visible? Target: under 2.5 seconds. Main culprits: heavy images, a slow server, and render-blocking resources.
Optimization built on Google's Core Web Vitals standard
Site speed optimization up to a 90+ Google score; measurable, not a claim
Every one second of load delay means a 7% drop in sales and falling Google rankings. Through multi-layer optimization, from server and caching to images and code, we get your site loading in under 2 seconds with a green Core Web Vitals score, and deliver the result with a before/after report.
- 90+ PageSpeed score
- A before and after report
- Your site's look stays untouched
- 3-to-7-day delivery
Where a speed project starts, and where it ends
Nothing changes on the site before it is measured. And it gets measured again at the end.

90+our PageSpeed target
- AuditThe site is measured with the Lighthouse engine to find where the time actually goes.
- PrioritiseOut of the eight layers, only the ones that move the needle on this site get picked.
- ImplementServer, cache, images, CSS, JavaScript and fonts. Without changing how the site looks or behaves.
- Before and afterA comparative PageSpeed report plus a maintenance guide, so the speed does not drift back down.
Speed has a ceiling on weak hosting. If TTFB is the bottleneck, the host has to change first, and we say so before the contract, not three months in.
Test your site's speed with Google's Lighthouse engine
Enter your site's address and we'll measure its real speed and Core Web Vitals metrics with the same engine Google uses for ranking (Lighthouse / PageSpeed Insights). A full analysis takes 20 to 60 seconds, it's worth the wait.
If Google's servers are busy, RGB's own dedicated analysis engine automatically takes over so you get a result without delay.
Why does site speed matter this much?
Speed isn't just a technical number; it directly affects three things: your Google ranking (Core Web Vitals is an official ranking factor), your conversion rate (users don't wait), and your brand's credibility (a slow site reads as an unprofessional business in the customer's mind).

Core Web Vitals: the three metrics Google uses to judge your speed
Since 2021, these three metrics have been part of Google's ranking algorithm. You'll see exactly these in the tool's report above:
INP: responsiveness to the user
When a user clicks, how long until the page responds? Target: under 200 milliseconds. Main culprits: heavy JavaScript and third-party scripts (popups, chat widgets, trackers).
CLS: layout stability
Do page elements jump and shift during load? Target: a score under 0.1. Main culprits: images without defined dimensions, fonts, and injected banners.
Site speed optimization services: what exactly do we do?
Depending on the audit result, a combination of these 8 layers gets applied to your site, without changing its look or functionality:
Server and TTFB optimization
Tuning the web server, PHP version, server-side caching (Redis/Memcached), and migrating to better hosting if needed, to get the first byte under 200ms.
Smart multi-layer caching
Page cache, browser cache, object cache, and smart preloading; return visits load nearly instantly.
Image optimization
Converting to WebP/AVIF, lossless compression, responsive sizing, and proper lazy loading, usually the biggest savings happen right here.
CSS and JavaScript optimization
Removing unused code, bundling and minification, deferring scripts, and injecting critical CSS so page rendering is never blocked.
CDN and geographic distribution
Connecting to the right CDN, to minimize the physical distance between the user and your content.
Fonts and third-party resources
Local fonts with proper font-display, removing unnecessary third-party scripts and managing the rest, the hidden killers of INP.
Database optimization
Cleaning up bloated tables, indexing slow queries, and optimizing WP_Query calls on WordPress sites.
Monitoring and a before/after report
An official before-and-after PageSpeed comparison report plus a maintenance guide, so speed doesn't drift back down over time.
Site Speed Optimization Pricing & Rates
Site speed optimization pricing is set by your site's type and the depth of optimization needed; every plan includes a before/after report and a results guarantee. If your site wasn't originally built with proper website design practices, part of the work goes toward fixing the underlying infrastructure; we tell you this transparently before starting too.
Prices are shown in US dollars and stay fixed regardless of exchange-rate swings; no need to call for the "real" price.

Speed Optimization Portfolio: Real Google Lighthouse Scores
These Performance scores were pulled from Google Lighthouse on sites under our own management. This isn't a claim; you can re-test every one right now on Google PageSpeed:
97Mobile100Desktop
95Mobile100Desktop
98Mobile100Desktop
The mobile score is Google's strictest measure, and above 90 means fully green. Rankesh, an image-heavy media outlet, sat at 89 for a long time; it is 98 now. One honest caveat: that is a lab number, not the real user experience. On that same Rankesh, real users' LCP over the last 28 days is 2.7 seconds, and Google still marks its Core Web Vitals as failed. What's your site's score right now? Check with the tool above.
Frequently Asked Questions About Site Speed Optimization
Clear answers to common questions before ordering.
How long does site speed optimization take?
Typical projects take 3 to 7 business days. Your site stays online throughout; every change is applied and verified in a test environment first, then moved over after approval.
Is a 90+ PageSpeed score really achievable?
Yes, it's fully achievable for most corporate and WordPress sites, and that's exactly what we target. For large stores with many scripts, a realistic target is 80+ on mobile with all three Core Web Vitals metrics turning green. The exact target number is agreed before starting and stated in the contract.
Does speed optimization break the look or features of my site?
No. Our method isn't blind stripping; every change is verified in a test environment first, and only moved over after confirming every part works correctly (forms, cart, sliders). A full backup is also taken before any work begins.
How much does site speed affect SEO?
Directly and officially: Core Web Vitals is part of the Google ranking algorithm. Its indirect effect is even bigger, a slow site produces a high bounce rate and low satisfaction, both strong negative signals to Google. Speed is a prerequisite for any serious website SEO project.
My site is on WordPress; which caching plugin do you recommend?
A plugin is only a third of the story, and the right choice depends on hosting and site structure (we typically use a professional FlyingPress or WP Rocket setup plus server-side caching). The other two thirds, images, fonts, third-party scripts, and the database, need specialized manual work, which is exactly what this service delivers.
How do I know the site is really faster after the project?
With official data, not a gut feeling: a before-and-after PageSpeed Insights comparison report (with a checkable link), plus this same tool above that you can re-test yourself whenever you want.
A slow site is costing you money every single day

Why site speed matters
Site speed matters, but not for the reason it is usually sold: its effect on Google rankings is small and conditional, and its effect on the person waiting in front of the page is large and immediate.
How a browser builds a page
The browser reads HTML from the first byte and builds the page tree as it goes, but it draws nothing on screen until it has understood the CSS, and if it reaches an ordinary script it stops right there.
Core Web Vitals in depth
Core Web Vitals is three numbers measuring three completely different things: LCP for how fast the largest element of the page appears, INP for how fast the page answers a click or a tap, and CLS for how much the layout shifts on its own.
How to measure site speed
Measuring site speed means taking one lab report, putting it next to data from real users, and picking a single task out of both.
Optimising images for the web
Optimising an image is three jobs, in this order of importance: resizing it to the size actually displayed, sending it in a modern format, and declaring its dimensions explicitly in the HTML.
What caching is, and its layers
A cache keeps the result of a piece of work so the same work is not done again next time.
