These days, a website is not just a bunch of web pages linked together to provide information about you and the services/products that you are dealing with, but, basically, it is one of the most important marketing tools to create an image for the organization.
Several years ago, the site was only meant to meet the needs of an online presence but gradually as people began to spend more time online, there is a new shift towards making the website a bit more user-friendly necessitating the relevancy of its content to give accurate information to its users. In fact, the relevance of the content has been further emphasized by Google through the famous Panda (2011) and Penguin (2012) update.
A good website design company should know the very objective behind having a website to prepare a design theme around a content strategy to improve the website so it has a good chance in the SERPs (Search Engine Results Pages). Developing the design theme having a prior idea about the kind of content that the website should be having is very much in these days.

Thus only emphasizing on design aspects while excluding aspects of the content to develop a design theme around is not a good strategy when the content is too important these days.
Thus, a good website designing company not only knows how websites are designed but also knows that they are relevant as well. So, one of the major criteria while choosing a website design company is that it should emphasis on using the latest and relevant technologies, and, of course, how it presents your website to make it user-friendly and engaging.
