Google and Matt Cutts announced that site speed is now a factor in Google’s ranking algorithm, this means you need to refine your websites and remove all unnecessary code. Clean coding is good coding, and will make your websites easier to update, maintain, and upgrade in the future.
One thing to note: Page load time is a small factor and will not be given the weight that other factors have; relevance, topicality, reputation, value-add, backlinks, keyword usage are all much more important ranking signals. Google uses over 200 elements in their search engine ranking algorithm, and page speed will affect less than 1% of all current search results.
Here are some page speed optimization tips that will help you decrease website load time.
Coding Best Practices For Fast Websites
- Make Fewer HTTP Requests
- Use a Content Delivery Network
- Add an Expires Header
- Gzip Components
- Avoid Redirects
- Put Stylesheets at the Top
- Put Scripts at the Bottom
- Avoid CSS Expression
- Reduce DNS Lookups
- Remove Duplicate Scripts
- Configure Entity Tags (ETags)
- Make AJAX Cacheable
- Remove External Third Party Scripts Such As: analytics, widgets, graphical icons, comments, social media (you can move th on your own server)
The insight behind these best practices is the fact that only 10-20% of the browser response time is spent getting the HTML document to the end user. Spend your time on the 80-90% that is hidden behind the page to make your pages noticeably faster. This is for optimizing the way servers and browsers handle that 80-90% of the user experience with advanced webpages.
