Most CMS market-share reports lump every site on the internet — Fortune 500, indie blogs, e-commerce stores, government — into one giant number. None of that data tells a small business owner what they need to know.
We audited 4,407 small business websites across 14 industries and fingerprinted what they actually run. Here's the real CMS landscape for small business in 2026.
WordPress adoption by industry
Professional service categories — dental, legal, accounting — over-index hard on WordPress. Restaurants, salons, and real estate skew toward template builders.
| Industry | WordPress share |
|---|---|
| Dental | 63.2% |
| Legal | 59.5% |
| HVAC | 58.9% |
| Contractors | 57.8% |
| Accounting | 57.1% |
| Pet services | 53.1% |
| Cleaning | 50.0% |
| Electricians | 48.3% |
| Medical | 42.7% |
| Plumbers | 42.2% |
| Restaurants | 34.7% |
| Auto | 32.8% |
| Salons | 29.3% |
| Real estate | 14.4% |
Wix and Squarespace: who actually uses them
Wix and Squarespace are sold as 'for everyone' but adoption is heavily skewed toward visual, photo-driven, low-touch industries.
- Wix is heaviest in salons (13.1%), cleaning (13.0%), and restaurants (11.9%)
- Wix is lightest in real estate (2.7%) and accounting (3.8%)
- Squarespace is most common in dental (5.7%), salons (5.4%), and restaurants (5.4%)
- Squarespace is essentially absent from real estate (0.9%) and accounting (1.5%)
Shopify, Webflow, and the rest
- Shopify: 4.0% overall — concentrated in retail-adjacent salons and pet stores
- Webflow: 1.1% overall — small but growing among design-conscious brands
- BigCommerce, Magento, Drupal, Joomla, and Ghost: each <0.5% — basically irrelevant to small business
What this means for owners shopping for a CMS
If your industry is dental, legal, accounting, or trades — your customers, vendors, and competitors are all on WordPress. The plugin ecosystem and freelancer talent is deepest there.
If you're in salon, restaurant, or cleaning — Wix and Squarespace adoption is real, but they're capped on speed, SEO, and conversion compared to a custom build. The data in our larger audit is unambiguous: template builders consistently underperform on Core Web Vitals, schema, and page weight.
We migrate 5–10 businesses off Wix and Squarespace every month. Performance and SEO gains are usually visible within 30 days.
Read the migration guideChoosing a CMS in 2026: a quick framework
- Need e-commerce + low effort: Shopify
- Need a content-heavy professional service site: WordPress (with a custom theme — not a $40 theme from ThemeForest)
- Need a beautiful brochure site under 5 pages: Webflow or custom-coded
- Need a hobby site / portfolio you'll never update: Squarespace is genuinely fine
- Need maximum performance, SEO, and conversion: custom-built (this is what we do)
Methodology
Sample: 4,407 small business websites audited Jan–Feb 2026 across 14 industries. CMS detection uses HTTP headers, generator meta tags, known asset path patterns (e.g. /wp-content, /_next, .squarespace-cdn.com), and JavaScript/CSS fingerprints. Sites can match more than one platform (e.g. WordPress + WooCommerce). 'Undetected' includes hand-coded sites, headless builds, and lesser-known builders our fingerprint set doesn't catch.
