For web agency they should know about things that are needed in designing a website in order to create optimal website for their respective customers. The first thing web agency should avoid is splash page because it does not have any meaning to the entire website. Some visitors may feel annoyed and hurriedly close the website. A huge number of advertisements are also a big no. Web agency may feel that it is important to get some attentions but what a company need is for someone that is influenced to buy their product not forcing them. The third thing is each web agency should make a simple easy to use navigation system. A complex navigation system will only make a visitor spend less time in that site. The next thing is never use any kind of sounds in the web site unless you will make a website that is purposed for children. If a web agency obey all those rules than they will surely create more effective website.
