The Visual Hundred: six measures of how much of the web now runs on pictures and video, from page bytes and alt text to visual search and YouTube, each drawn as 100 cells.
Six visual content and video statistics, each drawn as 100 cells. Hover or tap a panel for its exact definition. Highlighted: mobile pages whose largest element (LCP) is an image, the measure that matters most for SEO.
Each panel has its own base (adults, pages, bytes of traffic, searches, minutes), so the panels are not comparable with each other. The mobile traffic panel is an approximate figure from four European networks.
Page weight by content type: median mobile home page, kilobytes, July 2025
Each bar is the median for that content type, so the bars do not add up to the median total page (2,559 KB). On desktop, images were 1,058 KB of a 2,862 KB median home page.
Image format share of all images requested by mobile pages, %, 2024 (image SEO and file formats)
"WebP or AVIF" adds WebP (12%) and AVIF (1.0%). "Other" adds ICO (1.3%) and other or unknown formats (1.7%). JPEG fell from 40% of images in 2022. This is the 2024 Web Almanac; the 2025 edition has no media chapter.
Share of the top 1,000,000 home pages with a missing alt text error, %, by year
WebAIM's automated WAVE scan of the top million home pages, run each February. Detecting a missing alt attribute is not the same as judging alt text quality: WebAIM found another 10.8% of images with alt text had questionable or repetitive text.
Visual searches per month on Google (Lens, then all visual search), billions, as stated by Google
Google's wording: "more than 8 billion" (May 2022), "over 12 billion" (May 2023), "nearly 20 billion" (Oct 2024), "over 50 billion" (Oct 2026). Apr 2025 (~25B) is derived: Oct 2024 plus the "5 billion since October" Google reported. The Oct 2026 figure is for "visual searches" without naming Lens, so it may include Circle to Search and image queries in AI Mode.
YouTube's share of total U.S. TV watch time, %, selected months (video consumption trends)
Apr 2024 (~9.6%) is derived from Nielsen's statement that YouTube was "up 2.8 points since April 2024" at 12.4% in April 2025. Lines join only the months shown; Nielsen publishes every month.
Share of U.S. adults who say they ever use each platform, %, 2025 (social media visual content reach)
Pew survey of 5,022 U.S. adults, Feb. 5 to June 18, 2025. Pew reports Instagram as "half of adults." TikTok use was 21% in 2021.
