Every 100ms costs you conversion. We give them back.
A 1-second delay in mobile load time reduces conversion by up to 20%. A PageSpeed score below 50 is a direct SEO ranking penalty. Most sites scoring in the 20s and 30s have the same set of problems: unoptimised images, render-blocking JavaScript, no caching strategy, a bloated theme, and a hosting environment that was never designed for performance. We've seen these patterns across hundreds of sites and know exactly where to look, what to fix, and what order to fix it in. Most clients see 40–60 point PageSpeed improvements within the first engagement.
A PageSpeed score below 50 is a direct SEO ranking penalty and costs you 20% conversion per second of delay. Origin Softwares identifies and fixes the specific causes — unoptimised images, render-blocking scripts, no caching strategy — delivering 40–60 point PageSpeed improvements within the first engagement.
Why is website speed important for SEO and conversion?
Google uses Core Web Vitals (LCP, CLS, INP) as a direct ranking signal — sites that fail all three thresholds are at a ranking disadvantage against faster competitors. Beyond SEO, every 100ms of additional load time reduces conversion rate measurably. A 1-second delay in mobile load time can reduce conversion by up to 20%. Origin Softwares delivers 40–60 point PageSpeed improvements per engagement by fixing the root causes: unoptimised images, render-blocking JavaScript, missing caching strategy, and excessive third-party scripts. We have seen these patterns across hundreds of sites and know exactly where to look. Google's own data shows that pages loading in under 1 second convert 3× better than pages taking 5 seconds.
The problems this solves
- PageSpeed score below 40 directly affecting search rankings
- High bounce rate on mobile due to slow load times
- Third-party scripts (analytics, chat, ads) dragging down performance
- Field data (real users) failing Core Web Vitals despite passing lab tests
- E-commerce checkout abandonment on mobile due to speed
- Cannot identify which specific issues to fix first for maximum impact
Business outcomes
- 40–60 point PageSpeed improvement per engagement — measurable search ranking benefit
- 20% conversion improvement from 1-second load time reduction
- Lower bounce rate increasing effective traffic from existing organic and paid sources
- Passing Core Web Vitals thresholds providing search ranking advantage over competitors
- Reduced hosting costs through proper caching reducing origin server load
- 3x speed improvement typical on image-heavy sites
Who is this for?
E-commerce sites losing mobile sales
Every second of checkout delay costs you revenue — speed optimisation has direct, measurable ROI on e-commerce sites.
Sites with PageSpeed scores below 50
You are below the threshold where Google penalises you in rankings. The fix list is usually predictable and the improvement is dramatic.
Marketing sites with high ad spend
You are paying for traffic that bounces because the page is too slow — speed optimisation increases your return on existing ad spend.
Publishers with ad-heavy pages
Third-party ad scripts competing with content for rendering priority — proper loading strategy fixes this without removing revenue.
Sites passing lab tests but failing field data
Your real users on real devices have a worse experience than your lab tests show — we test on real hardware and optimise for actual conditions.
When Website Speed Optimization may not be the right fit
We'd rather tell you upfront than waste your time and budget.
- If the site scores 85+ already and the performance issues are perceived rather than measured
- If the underlying architecture is fundamentally incompatible with performance (a full rebuild may be more appropriate)
- If the performance problem is hosting infrastructure rather than code (we can advise but may not be the right fix)
- If the site needs a redesign anyway — speed optimisation on code that will be replaced is wasted investment

What are Core Web Vitals and how do you fix them?
Core Web Vitals are three metrics Google uses as a ranking signal: Largest Contentful Paint (LCP — main content load speed), Cumulative Layout Shift (CLS — visual stability during load), and Interaction to Next Paint (INP — response speed to user input). Origin Softwares fixes these at their root causes: LCP improves through image optimisation, font loading strategy, and server-side rendering. CLS improves through explicit image dimensions and font display strategy. INP improves through JavaScript reduction and main-thread optimisation. We deliver a ranked fix list with expected impact before starting work. The passing thresholds are LCP under 2.5s, CLS under 0.1, and INP under 200ms — measured at the 75th percentile of real-user field data.

Why Origin for Website Speed Optimization
Ranked fix list with impact estimates
We don't give you a generic Lighthouse report — we give you a prioritised list of fixes ranked by expected PageSpeed impact. You know exactly what each change will deliver before we start.
We fix the causes, not just the symptoms
Caching plugins mask slow pages; they don't fix them. We trace every performance problem to its root cause and fix it there — the result is a faster site, not just a higher score on one tool.
Real-device testing, not just lab simulations
Lab scores don't represent what your users experience. We test on real mobile devices on real connections and deliver field data alongside lab data in every audit.

Before you start — a checklist
Use this to prepare for your first conversation with us.
- Measure your current PageSpeed score on mobile — this is the baseline
- Check Chrome User Experience Report data — field data matters more than lab data
- Identify whether the site needs optimisation or a rebuild (if the architecture is fundamentally incompatible with speed)
- Determine which Core Web Vitals are failing (LCP, CLS, INP) — each has different causes
- List all third-party scripts and assess whether each is genuinely necessary
- Confirm that hosting infrastructure is not the primary bottleneck before optimising code
Maintenance & support
- Monthly Lighthouse and CrUX monitoring with trend analysis
- Alert when PageSpeed score drops below threshold
- Third-party script audit when new scripts are added
- Quarterly performance review and optimisation recommendations
- Image pipeline maintenance as new content is published
“We were scoring 22 on mobile PageSpeed and could see in the analytics that users were bouncing. Origin spent four weeks on optimisation — we're now at 81 on mobile, 96 on desktop. Organic traffic is up 28% in three months.”
Frequently asked questions
Planning & scope
- How much improvement can we expect?
- Sites scoring below 40 typically see 40–60 point improvements. The first fixes (images, render-blocking scripts, caching) deliver the most impact. Diminishing returns set in above 80 — going from 80 to 95 requires more effort per point than going from 30 to 70. We estimate expected improvement after the audit, before any work begins, so you can make an informed investment decision.
- Can you optimise without rebuilding the site?
- Usually yes — significant improvement without a rebuild. For WordPress: caching configuration, image format conversion, plugin reduction, CDN setup, and PHP version upgrade. For Shopify: image optimisation, script deferral, and theme code review. If the architecture is fundamentally incompatible with speed (a page builder generating unmaintainable markup), we will tell you honestly that a rebuild is more cost-effective.
Technical
- What is the difference between lab data and field data?
- Lab data (Lighthouse, PageSpeed Insights) runs in a controlled environment with a simulated connection. Field data (Chrome User Experience Report) comes from real users on real devices and real connections — often much slower than lab simulates. Field failures mean real users are having a bad experience. We test on actual mobile devices with throttled connections to understand real-world performance.
- How do you handle third-party scripts that slow the site?
- Defer loading until after the page is interactive where possible. For scripts that must load earlier (payment processors, auth), we optimise loading order to minimise LCP and INP impact. We use Partytown for analytics and tag manager scripts — this moves them off the main thread entirely so they do not compete with page rendering. Scripts that provide no measurable value are recommended for removal.
Engagement & process
- How long does a speed optimisation engagement take?
- Audit: 3–5 days. Implementation: 1–4 weeks depending on the number of issues and site complexity. The audit alone is valuable — it produces a prioritised fix list you can implement yourselves if preferred. Most clients choose full implementation because the fixes require technical expertise and measurement discipline.
- Will optimisation break anything on the site?
- We regression-test every change — visual comparison and functional testing before and after each fix. No change ships without verification that it does not break existing functionality. This is why we make changes in priority order with measurement after each one, rather than making all changes at once and hoping nothing broke.
