How Site Loading Times Affect SEO
In April of 2010, Google announced that it had added site speed to its search engine ranking algorithm. Site speed carries less weight than other ranking factors, so less than 1% of search queries were affected as a result of Google’s update. That being said, site speed isn’t just important for your search engine ranking; faster sites also improve user experience. Studies have shown that visitors spend less time on slow sites. That’s why it’s imperative to increase your site’s speed.
If your website takes less than two seconds to load, you’re good. Studies show, however, that users will leave a site if it hasn’t loaded in four seconds. So, if your website takes longer than four seconds to load, you’ll annoy your site visitors and your search engine rankings will probably be affected.
Check How Fast Your Site Loads
The first thing you need to do is determine how fast your site loads. You can check your site’s speed with the following tools:
WebPagetest allows you to test your site’s performance in different web browsers and geographic locations.
Pingdom Tools will test the load times of all elements on a web page and find bottlenecks.
GTmetrix will grade your site’s performance using information from Yahoo! YSlow and Google Page Speed and then provide you with actionable recommendations.
If you have a Google Webmaster Tools account, you can go to Labs > Site Performance to see how fast your site loads for users around the world.
How to Increase Your Site’s Speed
Here are several quick fixes that will help to increase your site’s speed:
Website Compression
Compressing your website’s content will decrease the time it takes for your web server to send content to your website visitors. Tools like Gzip compress the size of the page that’s sent to the browser, which will decompress the information before displaying it to users. A tool like Gzip is capable of reducing file size by upwards of 70%.
Minimize 301 Redirects
If possible, avoid using 301 redirects because they force the browser to a new URL and require it to wait for the HTTP request to come back.
Remove Unnecessary Code
Code for external services, such as a widget that shows your company’s most recent Twitter updates or social media “share” buttons, can slow your site down. If an external service isn’t absolutely necessary and is providing you with little benefit consider removing it.
Upgrade Your Hosting Package
Switch to a hosting company with a better reputation, or upgrade to a better package with your hosting company to increase your site’s speed.
Reduce HTTP Requests
Your website will load faster if there are fewer HTTP requests. To reduce HTTP requests, minimize the number of scripts, style sheets, images, and other items that need to be loaded.
Optimize Images for the Web
Don’t use images that are larger than necessary. In addition, when you save images in a program like Photoshop, click “save for web” instead of “save” so that the file size is smaller.
