My site doesn't qualify, what can I do?

Many sites won't qualify for the 512KB Club, but there are some quick things you could try to reduce the size of your site:

1. Replace custom fonts with a local font stack by replacing your font-family declarations in your CSS to one of the following:

# Sans-serif font stack
font-family: -apple-system, BlinkMacSystemFont, "Avenir Next", Avenir, "Nimbus Sans L", Roboto, Noto, "Segoe UI", Arial, Helvetica, "Helvetica Neue", sans-serif;

# Serif font stack
font-family: Constantia, "Lucida Bright", Lucidabright, "Lucida Serif", Lucida, "DejaVu Serif", "Bitstream Vera Serif", "Liberation Serif", Georgia, serif;

2. Optimise any images you have on your page. Short Pixel is a great service for this.

3. If all else fails and your site is pretty close the 512KB, but not quite there, why not apply for Bradley Taunt's 1MB Club instead?
