Before & After: what a rebuild actually changes
Two fictional local businesses. Same business, same photos. One 2012-style template site, and one site built the way we build today. Every score is measured, with the raw report linked.
Each comparison is a demo example / concept build, not a client result.

Key stats
- Mobile LCP
- 49.5 s to 1.4 s
- Page weight
- 9,701 KiB to 106 KiB
What we fixed
Speed
- 4096px unoptimized hero and galleries → responsive WebP (960/1280/1920) with a picture element portrait crop for phones; page weight 9,701 KiB → 106 KiB on first load (mobile)
- Render-blocking jQuery 1.8.3 and a slideshow script in the head → no blocking scripts; inline critical CSS; animation library loads after the page is visible
- Mobile LCP 49.5 s → 1.4 s; no layout shift (CLS 0)
Mobile & leads
- No viewport / desktop-only table layout → mobile-first layout with a sticky Call / Free Quote bar
- Phone buried in a grey footer as plain text → tap-to-call (555) 555-0100 in the header, hero, services, footer and mobile bar
- No clear call to action → “Get a free quote” on every screen; labeled quote form (name, phone, email, ZIP, service, details)
- “click here” links, marquee, hit counter → clear headings, trust strip, process, and FAQ
Accessibility
- No lang, no H1, images without alt, unlabeled inputs, low-contrast text → semantic landmarks, one H1, alt text and captions, labeled fields, AA contrast, skip link, keyboard-operable before/after slider, reduced-motion fallback
Search
- No title, no meta description, no canonical → full title, description, canonical, Open Graph and Twitter cards, share image
- No robots.txt or sitemap → robots.txt (search and AI crawlers allowed) plus sitemap.xml
AI & agents
- No structured data → JSON-LD graph: Plumber and LocalBusiness (address, hours, contactPoint, OfferCatalog), 6 services, FAQPage, WebSite, and WebPage
- No llms.txt → llms.txt with “When to use this site” and “How an agent should use this site”
- Markdown for agents: Accept: text/markdown on /, /about, /contact, and /privacy returns Markdown (with Vary: Accept); unknown paths return a Markdown 404 linking llms.txt and the sitemap
- About, Contact, and Privacy trust pages (500+ characters each), linked in the footer and sitemap
