About this episode

The episode discusses the implications of page size and weight for developers, users, and search engines, highlighting the challenges of HTML bloat and its impact on user experience.

In this episode of Search Off the Record, Gary and Martin dig into what "page size" and "page weight" actually mean for developers, users, and search engines. They discuss exploding web page sizes: median mobile homepages hit 2.3 MB in 2025 Web Almanac (up 3x from 2015), key insights for developers on page weight definitions, Googlebot's crawl limits, HTML bloat from structured data/images, and why size still hurts UX on slow connections despite faster networks. If you build or maintain websites, this conversation will help you rethink how much data your pages ship, where bloat really comes from, and why page weight still matters even as connections get faster.
