Content is King: Make sure that the content on your websites is useful and to the aspect. If your website content is not brief and apparent, people will lose interest from your website. On the other part, if you have a lot of useful information, post as much of it as you can.

Use of image: too many images on website look nasty and unprofessional. Lots of images also slow down the loading of website. Make sure that your images have been optimized. Optimized images will load quickly than images that are saved without any optimization.
