As the company website provides all necessary information and functions the only area that should be improved is a page design as well as a company image in general. This relates to brand logo at first as it will help to form trust and positive image from the customers’ perspective. Creating a logo contains a lot of potential advantages not only for the site improvement but for the whole brand in general. Link the homepage and logo is another possible idea for improvement as it would reduce unnecessary home link button from the navigation menu however the overall navigation menu as it was stated above doesn’t need any significant innovations.
But this does not related to the information structure and design. First recommendation is to design everything in one style - fixed font and font size for text, unified background and readable text color. Pictures should be inserted organically and fit the background and, what is more important, they should illustrate and add value to the text instead of overlapping it or stealing attention.
Another problem that requires immediate solution is English adaptation and grammar corrections. That doesn’t mean that a professional translator should be recruited but at least all the text should be checked for simple grammar mistakes. Otherwise the site seems as a quickie and unskillful work which, in turn, ruins any good impression of the site and the company as consequence.
Empty space could be used more efficiency. Providing related commercials is a good idea that can be developed – more advertiser might be attracted on barter terms for example.
