Can anybody suggest me how to reduce the overloading time of the website. How it will help in seo prospective. Please suggest me as ASAP?
By overloading you mean "longer load time"? Run an analysis of your site through this tool: https://developers.google.com/speed/pagespeed/insights/ This tool will suggest the issues you can fix to improve the load time of your site. However, you may need a developer/designer to fix those issues. Load time of a site is a factor of ranking in Google Algorithm. So, you will have to definitely optimize the load time. Also, a website that has quick server response and loads properly and quickly does not irritate your users and help you minimize the bounce rate of your site.
Another good tool for this is Firebug addon to Firefox. You can see which resources are loaded in which order and how much time is need for each resource to load.
OP. If you mean the page load time, you can get a quick measure of how your site speed using: http://tools.pingdom.com/fpt/ You can make images load faster by making them slightly smaller file size. You might do this by dropping the quality a little, and or scaling down the actual size. Some people do like to overload their pages with content, so having a well designed site with an appropriate amount of content per page, will let the page load faster. Using a CDN can also speed up the page load time for your visitors.
Resize your files especially images. It should help. Also try to look for web backgrounds (just in case you are using one) that are huge in resolution but small in file size. Or resize your images in photoshop and lower the quality to medium instead of high when saving.
and also search for these below factors: 1- use gzip 2- use css sprite in your themeplate 3-use httaccess in order to cache your images and other formats files of your themeplate to cache them in client browser for some days, things like your website logo and etc... that don't change regularely
tools.pingdom.com Use that tool to find out what is taking a long time to load (if anything). It will show you the DNS lookup times and the wait times for the server to respond with data for every file linked to by your page.
Sometimes we feel tired and feel that our computer is taking so long time to load a page. Actually our brain is got bored for long time monotonous work. We should enjoy sometime by visiting some awesome sites like www.wordsonimages.com
Javascript is often the main reason for a website to load slowly. Check your source and also check images if they are not really big!
Minify your CSS and JS.For example: To minify it just make it one line code. ....Make sure your external JS file is extracted to avoid long render blocking.
You should definitely look into a caching program or external DNS solution to speed up your site. Look at items that are load heavy and make sure all your html is optimized!
