Developing a website is quite tricky for many of us, that's why even if we know how to install Wordpress on the server and how to update the blog theme, we still need the services of a professional web design company.
As we want to offer to customer a good impression when he enters in our physic store, the same impression we want to offer him when he visits our website. I don't say that you can't build a website, with some basic knowledge you can build it, but for a professional website you need to go to a professional web design company.
A website can be seen by visitors as a beautiful one, a quality website or it can be seen as an ugly and hardly to use website – unhelpfully. Professional web designers recommend us to not use too many flash elements or too many big images – these things makes our site to move slowly and this is not an advantage.
Do not build your website very wide or very narrow. Most users use a resolution above 1024*768. If you want the professional web design company to build the website adapted for your screen resolution of 800*600, you lost the visitors interest. The same thing happens at a very wide website. It is not practical for visitors to scroll right or left to see the website content. In the last years a new trend evolved in web design field, a trend which allow any visitors(with any resolution) to see a website as it was build – it's known as Responsive Web design – a type of web design which adapt to any resolution, even for mobile browsers. You have to understand the fact that a professional web design company knows the most suitable solution for you and let them to do their job.
Don't insert all kind of scripts on the website(public chat scripts, pop ups) – will affect your visitors, whether they will see no activity on the chat and will think that the website is forgotten, or the website will move very slow and will negatively influence the visitors.
Do not ask visitors to download different browsers for a better accessibility of your website. Because there are a lot of website which can present the same information as you present, they will easily leave your website.
So, any extra element on your website will influence the design, and most importantly, will influence the visitors. In conclusion: Choose carefully what elements you want to implement on your website.
