Have you ever wonder how much a speed of a slow website costs the owner? Below are some statistics according to a survey done by Akamai and Gomez.com:
- 1 second delay in page response will lead to a 7% reduction in conversions.
- 47% of consumers expect web pages to load in 2 seconds or even less.
- 40% of them will abandon a website that takes more than 3 seconds to load.
- 79% of online shoppers who are dissatisfied with a website performance are less likely to buy from the same website again.
- If an e-commerce site is making $100,000 per day, a 1 second page delay could potentially cost you $2.5 million in lost sales every year.
If your website is slow there are a few usual suspects you should check:
1. Third-party online ad network
Online advertisement is one of the major ways to monetise your site but these can also slow down a website. So use them sparingly.
2. Poor choice of web host
When you are running a website that hosts a huge volume of files or is hit by traffic spikes, your web host may not have enough resources to accommodate all your website needs, especially true for those on a shared server environment. In this case, consider switching your web host which you can check out my reviews on my other post.
3. Too many widgets and plugins
As tempting as it maybe to get that new widget or that fancy plugins, you should keep it to the essentials for your site as the more you have the more your visitors’ browser has to download. Also if the widget or plugins are no longer updated, it is likely that it will severely slow down your site’s performance as it gets more out of date and may even break your site if it’s no longer compatible.
4. External embedded media
Videos, music and image slideshows are recommended to engage your audience but with great sources of content comes great slowness as visitors will have to spend more time downloading the images and videos. Never ever use flash, it’s already blocked by default on modern web browsers and given the age of Apple phones, it will not work. HTML5 is the way to go.
5. Large image file sizes
Images are great for your site but large images to your website can slow down the site when these images are loaded on browsers. A link to an image gallery may be better for mobile sites where the network may not be reliable or lower quality images can be used until they click for a higher resolution.
Make sure your Cache-Control and Expire headers are configured in order for visitors’ browsers to cache the content locally. This would reduce their need to requests for page components and result in faster speed.
