Analyze and Speed up Your Website :- Having your website load pages quickly and efficiently is more important than ever, not just from the stand point of ranking higher in search engines but also from a user experience point of view. Back in 2006, Amazon published information showing that for every 100 milliseconds faster their website got, their revenue increased by 1%. Recent Google data also indicates that users will spend 70% more time on your site if it loads in under 5 seconds.
Here I will show you how to analyze your website and carry out a few common and simple changes that will, in most cases, speed up a slow loading website dramatically and have users spending more time on your site as well as search engines favouring your fast loading website.
Tools For Analyzing Your Page Speed
There are a number of free to use tools out there to check over your pages and determine what’s slowing them down. These three, in my opinion, are the most popular and easy to use:
Pingdom, although it provides less information that the other two tools, the information it does offer is some of the most important and the corrections it shows, if corrected, will show some of the most immediate speed improvements to your pages.
GTMetrix is similar to Pingdom but shows much more information on how you can potentially speed up your pages. I generally use this after Pingdom, if my pages are still loading slow or if I feel I can get more speed out of them.
Google Page Speed, I find to be less important as the changes it recommends after using the other tools only ever really improve speeds by a small amount, if any at all, but it’s still a useful tool for improving your pages.
How to Speed up the Pages
Now that you know what’s causing the slow page speeds, it’s time to fix the suggested problem areas. There are a whole range of suggestions that may come up. I will only be able to cover a few of the most common problems, that should show immediate improvements to your web page’s loading times.
Nearly all of the problems that arise are pretty simple to fix, even for a novice and information on how to fix each one, that I’ve not covered, can be found with a simple web search.
Leverage Browser Caching
Browser caching essentially works by telling the user’s browser to request the web page’s resources from the browser, instead of from the web server. Although this won’t speed up the site for new visitors, it will drastically speed up your pages for returning visitors. To do this, you must add a few lines to your .htaccess file. Your .htaccess file can be found in the root folder of your website. If you do not have one, simply create a text file, add in the code below and save it as .htaccess within the root of your website.

Merge, Minimize and Move Resources
If the single files become too large, you can break them up into multiple files. However try to keep the files to a minimum. Once you have your final files, minimise them and save them. Then replace all the old references to them in your HTML with the new files.
Use a CDN for Your Resources
Loading static resources from a CDN can correct a couple of speed issues. This will allow your page to load while the browser fetches the content from another domain. This also allows you to fix the “Serve content from a cookieless domain” problem you may run into if your website is using cookies.
For example, for serving CSS, create a subdomain called
csscdn.yourwebsite.com and point it directly to your CSS folder within your website. Then on the front end instead of referencing the CSS files using
/css/styles.css, you use
Compress Your Images
These days image compression can be done without much, if any, noticeable loss to quality. There are a range of image compression techniques out there to use, including WordPress plugins and scripts that can compress your images upon upload, automatically. For manually compressing images, there is a free to use tool called Tinypng where you simply drag your images onto the page, it compresses the images and you can them download the compressed versions.
Compressing all your files can significantly increase the loading speed of your page. Tinypng is able to compress a 57KB image into a 15KB image without any noticeable quality difference at all. If your web page has large images or displays many images, just compressing all the images alone will make your page load in a fraction of the time.
