Case Study: How We Built a Sub-Second Website for a Bristol & Bath Construction Firm
Dropping heavy WordPress setups for Astro to hit 95+ Lighthouse scores and unlock real local trade leads.
For years, local construction companies and trades across Somerset have relied purely on word-of-mouth or Instagram to keep their diaries full. But when you are competing for high-value contracts—like premium loft conversions, home extensions, or heritage building restorations—relying on social media algorithms is a major business bottleneck.
When James Martin, Managing Director of Aspect Builds & Maintenance Ltd, came to us, he needed to transition his business from informal social channels to a proper, authoritative digital home targeting the Bristol and Bath region.
Instead of deploying a sluggish WordPress template or an over-engineered website builder, the team at SEO Kings built a custom, 40-page technical framework engineered entirely for pure organic search dominance.
Here is the exact technical blueprint we used to overhaul their presence, cut out performance bloat, and achieve flawless Lighthouse scores.

## 🛠️ The Stack: Why We Abandoned Legacy CMS for Astro
Most web design agencies in Bath and Bristol install bloated page builders that force mobile users to download megabytes of unnecessary JavaScript. If your website takes more than 3 seconds to load on a smartphone, your conversion rate collapses by over 50%.
To give Aspect Builds a permanent competitive edge, we skipped the templates and coded the entire project using **Astro**.
Astro is a modern web framework built strictly for content-driven websites. Its core superpower is “Zero-JavaScript by default.” It strips away unnecessary runtime scripts and ships raw, pre-rendered HTML to the user’s browser.
The results speak for themselves:
* **Lighthouse Scores of 95+:** The site clears Google’s Core Web Vitals checks with ease, ensuring perfect mobile rendering.
* **40 Highly-Targeted Landing Pages:** We constructed distinct, service-specific URLs for every core trade offering, from Velux loft conversions to Bath stone lime mortar repairs.
* **Instant Mobile Interaction:** Clients looking for a rapid project estimate aren’t left staring at a blank loading screen.
📍 Translating Site Speed into Google Map Pack Dominance
A fast site isn’t just great for user experience—it is the foundational baseline for elite search performance. Google’s modern ranking algorithm heavily favors sites that display content immediately.
By marrying a lightning-fast static frontend with aggressive local entity optimization, we built an underlying architecture that signals immediate trust to Google’s crawlers:
1. **Granular Service Mapping:** Rather than dumping all services onto a generic homepage, each service page answers specific client FAQs and maps directly to regional target zones around Keynsham, Saltford, and central Bath.
2. **Schema Integration:** Deep structural data is baked directly into the custom code, linking the digital profile explicitly to the physical trade business.
