Another important aspect to look for is their ability to implement SEO for your website.
SEO or Search Engine Optimization is one of the top priorities in website design. It involves many different aspects, but includes primarily using quality content that contains a good percentage of keywords.
When done properly, a website that utilizes SEO can be a powerful component in an online marketing campaign. It improves search rankings and natural traffic for your website, as well as reduce the amount of bounce on your website.
Bounce, in terms of a website, tends to happen when a website has been poorly designed to catch traffic. Using word placement that is not entirely relevant to the keywords used. Poorly designed content and improper use of SEO can result in a website that gets lost and buried among invalid search results.
Beyond just acknowledging SEO, the good web design company will demonstrate that they can utilize it properly.
You most likely got to this site by searching on Google for something like Pretoria web designers or something similar. That alone should tell you enough about the ability to help you with even just basic search engine optimization.
