I set the website up on a staging environment and deactivated all plugins, activating them 1 by 1 and then running it through GTMetrix measuring DOM size with each activation, here is the result…
GeneratePress Premium – Dom 256
GenerateBlocks – Dom 356
GenerateBlocks Pro – Dom 360
WooCommerce – Dom 413
Added Additional CSS – Dom 413
WooCommerce Stripe Gateway – Dom 413
Rank Math SEO – Dom 413
Rank Math SEO PRO – 413
Slider Plugin – Dom 1,784
Think I found the culprit…
