Methodology: Routeless audited 40 business websites in Naperville, IL (2026Q3 benchmark). Homepage signals (CMS, structured data, contact paths, analytics) were collected from each site's live homepage; performance figures are Google PageSpeed Insights mobile lab metrics for the 40 sites that completed a run. Businesses were sampled across industries from public listings and licensing registries; national chains were excluded. Sampled businesses include 360 Family Dental, Archer Dentistry - Naperville, Blue Seas Med Spa, Cap Dental Care, P.C., Compass Behavioral Health And Wellness. Collected August 25, 2026. Results describe the 40 sampled businesses, not every business in Naperville, and the benchmark is re-run, so these figures are a dated snapshot rather than a standing claim.

20.0% of the Naperville sites we audited run on a DIY builder. We write real code: sites that load fast, that are structured so Google and AI assistants like ChatGPT can read and cite them, and that connect to your booking, CRM, and phone systems.
Strategy, messaging, custom design and development, performance and accessibility, booking and intake integration — measured against the Naperville benchmark above before launch.
Customer portals, multi-location architectures, e-commerce and payments, dashboards — built on Next.js, Postgres, and AWS by the engineer who scoped them.
Structured data, technical SEO, a Google Business Profile review, and AI-readability foundations — the exact signals 22.5% of Naperville sites are missing. See how we run AI visibility and local SEO.
Guided intake, instant alerts, CRM pipelines, call and form attribution — the full lead intake system. 70.0% of the Naperville homepages we tested have no form at all; this is the layer that fixes it.
Every case study comes from a dated Search Console or Analytics record, ordered here by relevance to Naperville's industry mix.
When someone asks ChatGPT, or Google's own AI results, who to hire in Naperville, the answer draws on what those systems can read: fast pages, structured data, and consistent business information across the web. Structured data makes that information easier for search engines and AI systems to interpret and verify — and 22.5% of the 40 Naperville sites we tested publish none. That is an opening: businesses in Naperville whose sites are fast, structured, and consistent are easier for both Google and AI systems to surface than competitors whose sites are not.
We build for that standard and check the whole presence — your website, your Google Business Profile, and the listings AI assistants verify you against. We publish our research on how AI assistants recommend local businesses, one engineer owns your project from scope through launch, and fixed-scope builds start at $5,000 with the price in writing before work begins.
What your Naperville customers are choosing between, what proof moves them, and what the site must do — written into a fixed scope with a fixed price.
Custom design, real code, integrations with your booking, CRM, and phone systems. The engineer who scoped the project builds it.
Performance, structured data, analytics, and conversion paths verified before launch — the same checks this page ran on 40 Naperville sites.
Hosting, monitoring, security updates, and content changes handled by the team that built it. The first year of standard hosting is included.
Fixed-scope builds start at $5,000 and scale with page inventory, integrations, and custom functionality. Every Naperville project gets a written scope and a fixed price before work begins — no hourly surprises.
We audited 40 to find out. 100.0% take more than 2.5 seconds to show their main content on mobile, 22.5% have no structured data for search engines or AI assistants to read, and 30.0% run no analytics, so their owners cannot see what the site produces. The full benchmark is published on this page.

A complete new business website goes live in under two weeks from kickoff. Larger builds with portals, e-commerce, or custom integrations get their own written timeline with the fixed price, and the same engineer who scoped the project builds it.
