Better Site Speed: 4 Outside-the-Box Ideas
Most of us have done site speed audits, or seen audits done by others. These can be really helpful for businesses, but I often find they're quite narrow in focus. Typically we use well-known tools that throw up a bunch of things to look at, and then we dive into things from there.
However, if we dig deeper, there are often other ideas on how site speed can be improved. I often see plenty of opportunities that are never covered in site speed audits. Most site speed improvements are the result of a bunch of small changes, and so in this post I'm going to cover a few ideas that I've never seen in any site speed audit, all of which can make a difference.
A different angle on image optimization
Consider optimized SVGs over PNGs
I was recently looking to book some tickets to see Frozen 2 (because of, erm, my kids...) and so landed on this page. It makes use of three SVG images for transport icons:
SVG images are vector images, so they're well-suited for things like icons; if you have images displayed as PNGs you may want to ask your designers for the original SVGs, as there can be considerable savings. Though not always better, using an SVG can save 60% of the filesize.
In this case, these icons come in at about 1.2k each, so they are quite small. They would probably fly under the radar of site speed audits (and neither Page Speed Insights or GTMetrix mention these images at all for this page).
So you may be thinking, "They're less than 5k combined - you should look for bigger issues!", but let's take a look. Firstly, we can run them all through Jake Archibald's SVG compression tool; this is a great free tool and on larger SVGs it can make a big difference.
In this case the files are small, so you may still be thinking "
