Most websites still fall short on the basics. Only 48% of mobile websites pass all three Core Web Vitals (HTTP Archive Web Almanac 2025), 95.9% of the top million home pages have detectable accessibility failures (WebAIM Million 2026), and the median mobile home page weighs 2.56 MB. Meanwhile, mobile devices generate 58.99% of web page views worldwide (StatCounter, September 2026).
The 15 website statistics below cover how sites are built, how fast they load, mobile use, security, accessibility and who is actually visiting. Each figure is attributed to its original source, with links in the Sources section at the end.

What are websites built with in 2026?
1. WordPress powers 39.6% of all websites
According to W3Techs data for October 25, 2026, WordPress runs 39.6% of all websites and holds 58.3% of the content management system (CMS) market. That share is lower than a few years ago as hosted builders grow, but WordPress is still used by more sites than every other CMS combined. See our WordPress statistics for more.
2. Shopify runs 5.3% of websites, Wix 4.2% and Squarespace 2.4%
W3Techs’ October 2026 data puts Shopify second among content management systems at 5.3% of all websites, followed by Wix (4.2%), Squarespace (2.4%), Joomla (1.1%), Webflow (0.8%) and Drupal (0.6%). Another 32.1% of websites use no CMS that W3Techs can detect, such as hand-coded or custom-built sites.
| Platform | Share of all websites | Share of CMS market |
|---|---|---|
| WordPress | 39.6% | 58.3% |
| Shopify | 5.3% | 7.9% |
| Wix | 4.2% | 6.2% |
| Squarespace | 2.4% | 3.6% |
| Joomla | 1.1% | 1.6% |
| Webflow | 0.8% | 1.2% |
| Drupal | 0.6% | 0.9% |

How fast are websites in 2026?
3. Only 48% of mobile websites pass all three Core Web Vitals
The HTTP Archive Web Almanac 2025 performance chapter, based on July 2025 Chrome UX Report data, found that 48% of websites deliver a good experience on all three Core Web Vitals on mobile, compared with 56% on desktop. Core Web Vitals measure loading (LCP), responsiveness (INP) and visual stability (CLS), and they are part of Google’s page experience signals.
4. Loading speed is the weakest Core Web Vital: 62% of mobile sites have a good LCP
According to the same Web Almanac data, 62% of websites have a good Largest Contentful Paint on mobile, versus 77% for Interaction to Next Paint and 81% for Cumulative Layout Shift. Slow loading of the main image or text block is the most common reason sites fail Core Web Vitals on phones.
| Metric | Good on mobile | Good on desktop |
|---|---|---|
| All three Core Web Vitals | 48% | 56% |
| Largest Contentful Paint (LCP) | 62% | 74% |
| Interaction to Next Paint (INP) | 77% | 97% |
| Cumulative Layout Shift (CLS) | 81% | 72% |

5. The median home page weighs 2.56 MB on mobile
The Web Almanac 2025 page weight chapter reports that the median home page in July 2025 was 2.86 MB on desktop and 2.56 MB on mobile. The median mobile home page made 75 requests, and images (911 KB) were the largest single type of content.
6. The median mobile page loads 632 KB of JavaScript
HTTP Archive’s 2025 data shows the median mobile home page downloads 632 KB of JavaScript (697 KB on desktop). JavaScript has to be parsed and executed, not just downloaded, so heavy scripts are a common cause of poor responsiveness on mid-range phones.
Website statistics about mobile and security
7. Mobile devices generate 58.99% of web page views
StatCounter Global Stats data for September 2026 shows mobile devices accounted for 58.99% of worldwide web page views, desktops for 39.26% and tablets for 1.76%. A site designed desktop-first now serves the minority of its visitors.
8. 16% of US adults rely on a smartphone for internet access at home
Pew Research Center’s 2026 broadband fact sheet finds 16% of US adults are smartphone-dependent: they own a smartphone but do not have home broadband. The share is 24% among 18- to 29-year-olds and 29% among adults in households earning under $30,000 a year, so for many visitors the phone is the only way they will ever see a website.
9. 97.3% of mobile home pages are served over HTTPS
The Web Almanac 2025 security chapter reports that 97.3% of mobile home pages and 97.5% of desktop home pages are served over HTTPS, and more than 98.8% of mobile requests use HTTPS. A site without a valid SSL certificate now stands out, and browsers flag it as “Not secure”.
If your site still is not on HTTPS, our guide on how to enable an SSL certificate walks through the steps.
10. Let’s Encrypt issues the certificates for 52.6% of mobile pages
According to the same Web Almanac chapter, Let’s Encrypt, the free certificate authority, provides the certificates for 52.6% of mobile pages, down slightly from 56% in the previous edition. Roughly 76% of pages use TLS 1.3, the latest version of the encryption protocol.
Website accessibility statistics
11. 95.9% of the top 1 million home pages have detectable accessibility failures
The WebAIM Million 2026 report, based on automated tests of the top 1,000,000 home pages in February 2026, found detectable WCAG 2 failures on 95.9% of them. Automated tools catch only part of the accessibility problems a real user would hit, so the true failure rate is higher.
12. Home pages average 56.1 detectable accessibility errors
WebAIM found an average of 56.1 detected errors per home page in 2026, across an average of 1,437 page elements. More complex pages tend to have more errors, so every extra widget and pop-up adds risk.
13. 83.9% of home pages have low-contrast text
Low-contrast text is the most common accessibility error, found on 83.9% of home pages in the WebAIM Million 2026. It is followed by missing image alt text (53.1%), missing form input labels (51%), empty links (46.3%), empty buttons (30.6%) and missing document language (13.5%). All six are quick fixes for a site owner or developer.
Who is really visiting websites?
14. Humans generated only 47% of HTML page requests by December 2025
Cloudflare Radar’s 2025 Year in Review found that, as of December 2, 2025, human visitors made 47% of HTML page requests across Cloudflare’s network, while non-AI bots made 44%. AI crawlers averaged 4.2% of HTML requests over the year. Website analytics that do not filter bots can badly overstate real audience numbers.
What do these website statistics mean for your site?
The data points to a short checklist: design for phones first, keep pages light (especially images and JavaScript), make sure the main content loads fast, serve everything over HTTPS, and fix basic accessibility issues such as contrast and alt text. These are also the areas where most competing websites are weakest.
If you are starting a new site, a hosted builder handles much of this for you. Compare options in our best website builders guide, such as Squarespace or Wix, and see our guide to website costs. First, find an available name with the domain name generator.
How we compiled these statistics
We used large-scale, published measurements: HTTP Archive’s Web Almanac 2025 (built on Chrome UX Report and HTTP Archive crawl data), W3Techs technology surveys, the WebAIM Million 2026, StatCounter Global Stats, Cloudflare Radar and Pew Research Center. Older statistics from the previous version of this page, such as 2016-era bounce-rate figures, were removed because no current source supports them. All data is as of October 2026.
