For high quality website page load speed is very important. The user is only interested in the website load faster, even when a slow website response, will lose their patience and ability to be very thap.Ho back pay internet to enjoy the best service, fast Most, but not to white on a website and started waiting.
Improved page load speed is important not only for users but also important voicong search engine. April last year, Google announced the page loading speed is one of the ranking factors in their algorithms.
1. Check the speed of website
Analyzing the page loading speed will monitor the level of improved speed when loading design websitemoi you have any modifications.
There are many free tools to check how long it takes to load your website design. Here are a few of them:
Pingdom: check website for page load speed is very easy to use, you only need to enter the website and press the test button.
Page Speed: Firefox add-ons to help evaluate the performance of the site, in addition to providing advice how to fix the problem.
Web Page Test: another great tool for you to see the speed and efficiency of web pages in different browsers.
2. Optimize image
You must know how to use image formats suitable for each location on your website. Change the image file format can significantly reduce the size of the image.
Gif: Use good for simple image like little color logo.
JPEG: fine detailed images and colors.
PNG: Used when you need high-quality images
3.Khong decrease the image.
In HTML tags you can set attributes with x hight of the desired images, but not so overused image size larger than you actually need. If you need an image 100 x 100 and you have 1 700 X 700 image use photoshop or a photo editing service on the web to resize as you want. This significantly reduces page load time. /
4.Nen and optimize your content.
Compressing content websites huge impact on reducing load time. When using HTTP compression method, all your website data is sent in a smaller file instead of many different files. See more on Wikipedia HTTP compression.
You should also optimize website and compress JavaScript and CSS files in the source code optimization process.
5.Dat stylesheet file on TOP
Put references in the document stylesheet html help websites load faster, and strict W3C standards
6 Put the script at the bottom
If you add the script to the head of the html file it will block anything below it at the download page. This sensation slower loading web pages.
To avoid this situation it is best to put the scritp after closing
7. Place the javascript and css in a separate file
If javascript and css placed directly in the html document, it will be downloaded at the same time every html file is required. This does not take advantage of the browser's cache and increase the size of the html file.
Always put javascipt and css in a separate file for easy maintenance and updates.
8 Minimizing HTTP requests
When on a web page, most of the time used to account for the composition of that site (images, css, scripts ...)
To speed up page load we need to minimize the requirement that a website should be provided. To reduce HTTP requests for images to use CSS sprites to combine multiple images.
If there are multiple stylesheets and javascript library, consider combining them to reduce the number of HTTP requests.
9. Cache your site
If you're using a content management system (CMS), you should use the cache. Cache is how to create a static version of the site on the user's computer. Creating cache reduces server load stress for both speed and page load time savings for users when accessing your site. Rather than require reloading the entire web page, the browser just retrieve information from web pages were static version cached on the user's computer.
10. Reduce the 301 redirects
Each using 301 redirects it forces the browser to redirect to a new URL increases page load time. So avoid using 301 redirects.
