 It's important to note that our analysis differs from other commonly used datasets, such as W3Techs. These deviations are due to differing research methodologies and definitions of what qualifies as a CMS, which impact the final statistics.

 A CMS and content on it is generally set up to serve as much information to search engine crawlers as possible to make it as easy as possible for them to index site content appropriately in search engine results. Compared to a custom-built website, one might expect a CMS to provide good SEO capabilities, and the Lighthouse scores in this category remain appropriately high.

 We leveraged HTTP Archive data to analyze the resource weight across various CMS platforms, aiming to uncover opportunities for performance optimization. While page loading speed isn't solely determined by the number of downloaded bytes, reducing the amount of data required to load a page offers several advantages.
 
-Fewer bytes mean lower bandwidth costs, reduced carbon emissions, and faster performance—particularly for users on slower connections. This analysis sheds light on areas where resource optimization can have a meaningful impact on both user experience and sustainability. Read the [Page Weight chapter](../2022/page-weight) for a more detailed analysis.

 #### Including as little code as possible directly in HTML
 
 The practice of inlining JavaScript and CSS directly in HTML can bloat HTML files and potentially harm overall performance and sustainability, as well as security. This issue is particularly prevalent in websites built with Content Management Systems (CMS) and those implementing the [Critical CSS method](https://web.dev/articles/extract-critical-css).
