While bundling up a recent side project for launch, I had to generate favicons for the project. A simple side project, the favicon was basically just an emoji. Rather than generating a bunch of png and ico files, could I just use the emoji directly?

Lazy loading background images to improve load time performance

Lazy loading of images helps to radically speed up initial page load. Rich site designs often call for background images, which can't be lazily loaded in the same way. How can we keep our designs, while optimising for a fast initial load?

Font Subsetting - shrink down font files to speed up page loads

Fonts are one of the largest resources on any page after images, and can have a big impact on CLS when they vary in size from the underlying system font. Font subsetting allows us to radically shrink font file sizes, speed up initial page loads, and improve our page speed scores.

Minimising Cumulative Layout Shift (CLS) When Loading Responsive Ads

Responsive ads are a great way to maximise publisher revenue from display ads. Not knowing the size of the ad to be served in advance can have a big impact on Cumulative Layout Shift (CLS), and, ultimately, Google rankings. How do we maximise revenue while minimising CLS impact?

These metrics will be used in the Google rankings for a page, so what are the common optimisations we can make to ensure our pages score well?
