Original research

The 2026 Routeless Local Website Benchmark: Caldwell.

We ran 34 Caldwell business websites through the same audit (13 legal, 11 home services, 10 healthcare): homepage checks plus Google's mobile performance test. We collected the data August 25, 2026 and left out national chains. Caldwell is one of 336 US cities in the benchmark.

  • 97.1% took over 2.5s to show their main content on mobile Largest Contentful Paint above Google's 'good' threshold, 34 sites tested
  • 69.5/100 median mobile performance score Google PageSpeed Insights lab score across 34 sites
  • 6.4s median time to largest content on mobile Google recommends 2.5 seconds or less
  • 20.6% have no structured data at all machine-readable markup that describes the business and page
  • 50.0% run no analytics or conversion tracking we could detect no Google Analytics, Tag Manager, or ad pixel on the homepage
  • 67.6% have no contact form on their homepage a visitor's only next step is a phone call or leaving
  • 20.6% run on a DIY site builder Wix, Squarespace, GoDaddy builder, Weebly, or Duda
  • 1.9MB median homepage weight total mobile download across 34 tested sites

The fastest homepage in the Caldwell sample showed its main content in 0.8 seconds, the slowest took 25.3, and the middle half took between 4.2 and 11.1. The lightest homepage weighs 9 KB; the heaviest sends 16.4 MB to a phone.

Everything we measured in Caldwell, from worst to best. The 50th column is the typical site. Beat the 90th column and you're ahead of nine in ten sites we tested:

Methodology: Routeless audited 34 business websites in Caldwell, ID (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 34 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 Caldwell benchmark summary. We dropped 6 Caldwell sites we couldn't reach, and 34 of the 34 finished a full PageSpeed run. Sampled businesses include A-V Emergency Plumbing Repair, Ankrum Law Group PLLC, Briggs Law Office, Caldwell Law Group, Smiles 4 Kids Dentistry for Children, Caldwell Dentistry Co., Caldwell Family Dentistry. Collected August 25, 2026. Results describe the 34 sampled businesses, not every business in Caldwell. We re-run the benchmark, so treat these numbers as a snapshot from that date.

Benchmark observations

What we found analyzing 34 Caldwell websites.

  • 76.5% of the Caldwell 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.
  • 23.5% of the 34 sites have no sitemap we could find, so search engines have to discover their pages by following links.
  • Only 14.7% 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.
  • 0.0% of the sampled sites let visitors book or schedule online.
  • 47.1% run on WordPress and 20.6% on DIY builders. The rest are custom, or we couldn't identify the platform.
  • 67.6% of Caldwell homepages have no contact form, and 32.4% have no tap-to-call phone link on mobile.
  • 50.0% of the Caldwell 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 Caldwell site takes 6.4 seconds to show its main content on a phone. Every figure above comes from the same 34 sites.

Buyer guide

What to look for in a Caldwell 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 Caldwell 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
  • 10Caldwell 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 9 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 4, 2026.

What we build

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

20.6% of the Caldwell 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. 20.6% of the Caldwell 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 Caldwell, 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. 20.6% of the 34 Caldwell 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 Caldwell 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 Caldwell 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 34 Caldwell sites above.

FAQ

Questions Caldwell businesses ask.

A Caldwell business website on Routeless Go costs $99 a month once you publish, with no setup fee. You can look through three designs before you pay. Projects that need integrations or other custom work are quoted after we review them. We found prices you can compare for 2 of the 10 agencies we reviewed.

We scored 10 agencies serving Caldwell on public evidence: portfolio, case studies, technical quality, reputation, services, local relevance, and transparency. The top three in our 2026 review are Thrive Web Designs (Best for client satisfaction), Idaho Websites (Best for diverse service offerings), Gempop Marketing and Design (Best for local presence). Routeless publishes the research, so we list it as our pick and leave it out of the ranking. The full comparison and methodology are on this page.

Agency Intelligence is a separate study from the local business website benchmark. We scored 10 providers on the same 100-point rubric, using only what we could verify in public, and ordered the 9 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 34 Caldwell business websites. 97.1% take more than 2.5 seconds to show their main content on a phone. 20.6% have no structured data for search engines or AI assistants to read, and 50.0% run no analytics, so those owners can't see what their site brings in. The full results are on this page.

No. Routeless is a remote engineering team that works with businesses in Caldwell and across the US. The research on this page is local, though: the benchmark covers 34 Caldwell business websites, and the market figures come from U.S. Census data for Caldwell and Canyon County.

The industry sections on this page follow the largest sectors in Caldwell: construction, retail, health care and social assistance. Go works the same way for any kind of business. The latest County Business Patterns count puts Canyon County at 5,933 business establishments.

The Caldwell sites we tested have a median mobile performance score of 70/100. The median site takes 6.4 seconds to show its main content, and Google calls 2.5 seconds or less 'good'. We test every site we build for mobile speed before launch.

Yes. 20.6% of the Caldwell sites we audited run on a DIY builder and 47.1% on WordPress. We move your content over, redirect old URLs that get search traffic, and build the new site around what you sell.
