1 AVOID LARGE FRAMEWORKS

Frameworks and libraries can be needlessly large. Pare them down to the functionality your site uses.

2 USE CSS FOR BUTTONS

Using images for buttons creates an unnecessary download. Instead use CSS to create page elements like buttons.

3 COMPILE & MINIFY

Compile multiple scripts that will be used together to avoid separate downloads. Minify them to save processing time.

4 USE A GLOBAL CDN

With datacenters all over the globe, content delivery networks can use the shortest and fastest route to deliver your page.

5 MINIMIZE REDIRECTS

Redirect chains bounce visitors from one URL to another, extending the time before page loading can begin.

6 CUT DOWN REQUESTS

Each and every script or image requires requesting the item from the server. The latency – or the time it takes the server to respond – adds up on request heavy pages.

7 OPTIMIZE IMAGES

Needlessly downloading large images and resizing them to fit is a waste of bandwidth and increases download & rendering time.

8 USE SPRITES FOR ICONS

Load just one image with all of your icons and use CSS positioning to display only the icon needed for each instance.

9 DON’T BLOCK RENDERING

Faster rendering pages appear to load quicker. Put off loading external JavaScript files until after the page has rendered.

10 DON’T HIDE

Hidden elements are needless bandwidth. If an element isn’t going to show up, why even download it?

{display:  none;}  

11 LAZY LOAD EVERYTHING

First load only what you absolutely need to render the view. Then load slower page elements that aren’t immediately on screen - like Social Buttons.

12 CACHE & REUSE

Logos and icons often appear multiple times over a visit. Caching them prevents the visitor from having to re-download.
