Original research

The 2026 Routeless Local Website Benchmark: Castle Rock.

We ran 33 Castle Rock business websites through the same audit (16 healthcare, 13 legal, 4 home services): homepage checks plus Google's mobile performance test. We collected the data August 25, 2026 and left out national chains. Castle Rock is one of 336 US cities in the benchmark.

  • 93.9% took over 2.5s to show their main content on mobile Largest Contentful Paint above Google's 'good' threshold, 33 sites tested
  • 56.0/100 median mobile performance score Google PageSpeed Insights lab score across 33 sites
  • 7.4s median time to largest content on mobile Google recommends 2.5 seconds or less
  • 27.3% have no structured data at all machine-readable markup that describes the business and page
  • 45.5% run no analytics or conversion tracking we could detect no Google Analytics, Tag Manager, or ad pixel on the homepage
  • 66.7% have no contact form on their homepage a visitor's only next step is a phone call or leaving
  • 15.2% run on a DIY site builder Wix, Squarespace, GoDaddy builder, Weebly, or Duda

Methodology: Routeless audited 33 business websites in Castle Rock, CO (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 33 sites that completed a run. Businesses were sampled across industries from public listings and licensing registries; national chains were excluded. Read Google's PageSpeed Insights methodology and download the anonymized Castle Rock benchmark summary. We dropped 7 Castle Rock sites we couldn't reach, and 33 of the 33 finished a full PageSpeed run. Sampled businesses include Ferraro Law Firm, Boyd Chiropractic Centers, Castle Rock Counseling, Castle Rock Dental Group, P.C., Oakwood Dental, Castle Rock Dental Center, Castle Rock Family Dental. Collected August 25, 2026. Results describe the 33 sampled businesses, not every business in Castle Rock. We re-run the benchmark, so treat these numbers as a snapshot from that date.

Benchmark observations

What we found analyzing 33 Castle Rock websites.

  • 87.9% of the Castle Rock business sites we tested fall in Google's 'poor' range for loading: their main content takes more than four seconds to appear on a phone.
  • 21.2% of the 33 sites have no sitemap we could find, so search engines have to discover their pages by following links.
  • Only 6.1% of the sites we tested get enough traffic for Google to publish field speed data, which is measured on visitors' own devices. The rest have lab scores only.
  • 9.1% of the sampled sites let visitors book or schedule online.
  • 42.4% run on WordPress and 15.2% on DIY builders. The rest are custom, or we couldn't identify the platform.
  • 66.7% of Castle Rock homepages have no contact form, and 24.2% have no tap-to-call phone link on mobile.
  • 45.5% of the Castle Rock sites run no analytics we could detect, so those owners can't easily see how many visits or inquiries the site brings in.

The median Castle Rock site takes 7.4 seconds to show its main content on a phone. Every figure above comes from the same 33 sites.

Buyer guide

What to look for in a Castle Rock web design company.

Past work

Portfolio work you can inspect

Ask for recent, named projects you can open, and case studies that say what was done and what changed. A live site you can click through tells you more than a wall of client logos.

Speed

Test the agency's own website

Speed is one part of the decision, and anyone can test an agency's own site. The table above shows the same mobile score for every provider.

Specialty

Match the team to the build

A branding studio, a WordPress shop, an ecommerce team, and a software developer each solve different problems. Pick the team that has built the kind of site you need.

Ownership

Know who does the work

Ask who plans, designs, builds, launches, and maintains your site. Get what's included in writing, and ask how they handle changes to price or timeline.

Agency Intelligence methodology · version 2026-10

How we evaluated Castle Rock web design agencies.

Scores count only what we could verify in public. If an agency doesn't publish case studies, reviews, pricing, or other proof, it gets no points for that part of the score. That doesn't mean its client work is poor.

  • 25Portfolio and demonstrated work
  • 20Public case-study evidence
  • 15Technical website quality
  • 15Verifiable public reputation
  • 10Service depth
  • 10Castle Rock market relevance
  • 5Transparency

Choosing which agencies to review is a separate step from ranking them. For that step we look at local relevance, brand searches, how often an agency appears across independent search results, how much public evidence it has, reputation, and a mix of specialties. Every agency that makes the list is scored on the same 100-point Agency Quality rubric, and the 7 ranked agencies are ordered by that total alone. Routeless publishes this research. It's listed as our pick and isn't ranked, so no score is adjusted in its favor. Its remote setup and lack of third-party reviews are scored as found. Technical scores come from each audit, and audits and source facts are dated September 1, 2026.

What we build

A website you can run yourself, with the tools around it.

15.2% of the Castle Rock sites we audited run on a DIY builder, and those owners usually pay separately for plugins, forms, and hosting. Routeless Go puts the website, the lead inbox, analytics, and content publishing in one account, and sets up the search basics for you.

Routeless Go

Three designs, then one place to run the site

Go drafts your pages from your business details and shows them in three designs. After launch you change the site by clicking or asking, get every inquiry in one inbox, and see where visitors come from.

Search & AI visibility

Found by Google and by assistants

Page titles, descriptions, structured data, and a sitemap are set up on every Go website. 27.3% of the Castle Rock sites we audited publish no structured data at all.

Search and AI assistants

People also ask AI assistants who to hire.

When someone asks ChatGPT or Google's AI results who to hire in Castle Rock, the answer draws on what those systems can read: your pages, your structured data, and business details that match across the web. Structured data makes that information easier for search engines and AI systems to interpret and verify. 27.3% of the 33 Castle Rock sites we tested publish none.

We also check your Google Business Profile and the listings AI assistants compare you against. Every Go website comes with structured data and a sitemap, and we publish our research on how AI assistants recommend local businesses.

How it works

From business details to a live Castle Rock website.

1 · Details

Tell Go about your business

Start with your current website, your Google Business Profile, or a few details about what you do and where in Castle Rock you work.

2 · Designs

Look through three designs

Each one uses your services and what you want customers to do: call, book, or ask for a quote. Nothing to pay yet.

3 · Changes

Make it yours

Change the copy, photos, colors, and pages directly, or tell Go what you want in plain English.

4 · Publish

Go live for $99 a month

Connect your domain and publish. Hosting, the lead inbox, analytics, and content tools are included, and you can compare the live site with the 33 Castle Rock sites above.

The top three in our 2026 review are ZING Website Design & Business Services (Best for diverse service offerings), Tag Team Design - Denver Web Design & SEO (Best for positive client feedback), CoraForge llc (Best for local presence).

Agency Intelligence is a separate study from the local business website benchmark. We scored 8 providers on the same 100-point rubric, using only what we could verify in public, and ordered the 7 ranked agencies by that total alone. An agency that doesn't publish something gets no points for it. That doesn't mean its client work is poor.

We audited 33 Castle Rock business websites. 93.9% take more than 2.5 seconds to show their main content on a phone. 27.3% have no structured data for search engines or AI assistants to read, and 45.5% run no analytics, so those owners can't see what their site brings in. The full results are on this page.
