Website Speed Test : Speed Optimization

Website Speed Test

Website Speed Test is important.Because Slow speeds kill conversions.In a Blog, Kathryn Aragon mentioned – A one-second delay in page load time yields:11% fewer page views,16% decrease in customer satisfaction,7% loss in conversions.So only a few seconds can make a huge impact on your page rankings.47% of customer expect a page to be load in 2 sec or less and 40% will close a page if it will take more than 3 sec.This info will make you aware how page speed is a factor for your ranking.Minimize HTTP Requests to speed up your page loading, Reduce your server response time, Enable compression, Enable your browser caching, Minify your Resources, Optimize images, Optimize your CSS Delivery, Prioritize above-the-fold content.

Enable Compression

Use Gzip, a program application for file compression, to reduce the size of your CSS, HTML, and JavaScript files that are bigger than 150 bytes.

Do not use gzip on picture files. Rather, compress them in a program like Photoshop in which it is possible to retain control over the character of the picture. See”Optimize pictures” below.

By optimizing your code (including removing spaces, commas, and other unnecessary characters), it is possible to dramatically boost your page speed. Google recommends using CSSNano and UglifyJS.

Reduce redirects

Each time a page redirects to a different page, your visitor confronts additional time for the HTTP request-response cycle to finish. For instance, if your cellular redirect pattern looks like this:”example.com -> www.example.com -> m.example.com -> m.example.com/home,” all those two extra redirects makes your page load quicker.

Eliminate render-blocking JavaScript

Browsers have to build a DOM tree by parsing HTML before they could leave a webpage. If your browser experiences a script during this procedure, it must stop and execute it before it could continue.

Google suggests avoiding and reducing the usage of blocking JavaScript.

Browsers cache a great deal of information (stylesheets, images, JavaScript files, and much more ) so that if your visitor comes back to your site, the browser does not have to reload the entire page. Use a tool like YSlow to find out if you currently have a expiration date set for your cache. Then place your”expires” header for the length of time you want to have that information to be redeemed. In many cases, unless your site design varies frequently, a year is a reasonable time period. Google has more information about leveraging caching here.

Boost server response time

Your server response time is influenced by the amount of traffic you get, the resources each page uses, the software your server uses, along with the hosting option you use. To improve your server response time, look for performance bottlenecks such as slow database queries, slow routing, or a lack of adequate memory and repair them. The perfect server response time is under 200ms. Find out more about optimizing your own time to first byte.

Utilize a content distribution network

Content distribution networks (CDNs), also referred to as content delivery networks, are networks of servers which are utilized to disperse the load of delivering content. Essentially, copies of your site are stored at multiple, geographically diverse data centers so that consumers have faster and more reliable access to your site.

Optimize images

Make certain that your images are no larger than they need to be, they are in the right document format (PNGs are usually better for graphics using fewer than 16 colours while JPEGs are usually better for photos ) and they are compressed for the internet.
