How to speed up page load times?

It is widely accepted that fast-loading pages improve the user experience. In recent years, many sites have started using AJAX techniques to reduce latency. Rather than round-trip through the server retrieving a completely new page with every click, often the browser can either alter the layout of the page instantly or fetch a small amount of HTML, XML, or javascript from the server and alter the existing page. In either case, this significantly decreases the amount of time between a user click and the browser finishing rendering the new content.

However, for many sites that reference dozens of external objects, the majority of the page load time is spent in separate HTTP requests for images, javascript, and stylesheets. AJAX probably could help, but speeding up or eliminating these separate HTTP requests might help more, yet there isn't a common body of knowledge about how to do so.

In today’s world where time is everything; those who are surfing the internet and looking for some useful informative content, wants everything they are looking for in max. 5 seconds. If it takes any longer then users are all likely to push the “back” or “close” button, leaving your site nowhere.

So if any of the website took ages to load; is certainly going to loose on every business front. Who’s going to wait to explore your website if your pages downloading slowly? Neither site visitors and of course not even you. A fast loading website holds the attention and encourages visitors to explore every aspects of your website which is directly proportional to higher sales.

You can make site of multiple pages and add necessary artistic decorations but must adhere to certain set of rules to minimize wait time:-


Appropriate graphics usage: Using too many graphics is the sole reason in 9 out of 10 cases which slowdown your website’s downloading speed. Therefore, always do the best efforts to reduce the number of images and pictures in your web pages. If it’s a must necessity then try to repeat the same graphic on other pages also instead of using different ones because once downloaded it got stored in a computer’s cache and there is no need arises to download it again.

Decrease the quantity of colors: You should better reduce the numbers of colors used in the graphics. Try to avoid using GIF or JPEG files which requires thousands of colors. Using fewer colors significantly low down the size of the graphics which subsequently enhances site’s downloading speed.

Use html text: As the size of html text is much smaller than the graphic textso try to use it in abundance as it will decrease your page size which speed up downloading.

Avoid redundancy in coding: Designing a site using softwares such as frontpage, dreamweaver etc often add unnecessary scripting codes that will make the page unnecessarily larger and make it harder to crawl. That’s why it’s better to minimize such coding; it might save 1/3rd of your downloading time.

Use CSS: CSS generally requires less code. All code relative to layout can be placed in an external CSS document, which will be called up just once and then cached on the user’s computer. Web page using CSS are mostly smaller than the tabular layouts. With CSS you can control the downloading order of the items on to the screen i.e. You can make the content appear before slow-loading images.

Minimize flash usage: Most cool websites with fancy effects are built using Flash. Its ok with using decorative images for banners and other necessary branding but you should avoid them in rest of the segments. Avoid strewing images over the site just to add glitter. It’s good to populate your website with useful images rather than decorative ones as it causes slow page loading. So try to avoid using flash unless it is absolutely necessary.

Use fewer links: Try to minimize the use of links to max. 6-7 links per page. As fewer links requires less memory and comparative easy downloading. Using too many links other than decreasing the download also confuses visitors. So try to keep them simple and neat.

Include height and width tags: You should better include height and width tags on your page graphics source tags. This allows the browser to “pre-allocate” the space for the graphic on the display, which ultimately speed up downloadings. In addition using ALT tags with the images is also beneficial relative to downloading speed.

Avoid free hosting: Server speed of your website host largely influence the speed of your website’s downloading speed. So it’s better to avoid “free” hosting as nothing is really free. It lacks the resources to provide fast and reliable servers.
