Speeding Up Your Site
Caught up with SEO Revolution’s blog, where Jerry West picked up on a forum post from Webmaster World. Yahoo’s Steve Souders gives fourteen best practices (worth working through this page) to speed up webpages from Yahoo’s research. The findings focus on client-side Web development and making page load times faster to real users. It’s a good list and sums up a lot of key factors well:
- Make Fewer HTTP Requests
- Use a Content Delivery Network
- Add an Expires Header
- Gzip Components
- Put Stylesheets at the Top
- Put Scripts at the Bottom
- Avoid CSS Expressions
- Make JavaScript and CSS External
- Reduce DNS Lookups
- Minify JavaScript
- Avoid Redirects
- Remove Duplicate Scripts
- Configure ETags
- Make Ajax Cacheable
There are a few other important factors missing from this list that’ll help speed up page load times even more:
- Aim to keep all image filesizes below 20kb
- Write W3C Valid HTML and CSS code. This negates the need for browsers to use error correction algorithms
- Use Server-Side Include (SSI) files as much as possible
