A web site is like a storefront or an office where people visit and see what your site is all about, be it a blog, if so, read it and comment, be it a E-commerce store where you sell goods and or services, if so, connect with you and or conduct business and or make payments etc, be it a simple information site, if so then read it, etc
Just creating it one time and not updating it periodically or not taking care of the business needs, defeats the whole point of creating a site in the first place. Hence working on the website, means two things (1) taking care of the background technical stuff like ensuring that no viruses attack your site, site never goes down, you need to back up the content periodically, writing new blog content, updating new images, adding new, editing or deleting pages etc or (2) the front end stuff like helping clients, when some one comes to your site, replying to emails, answering phone from the site, fulling orders etc
Fortunately we can do it almost all of it, back end and front end service. Since these services can have a very varied dimension that it is better to understand your specific needs and we shall custom tailor solutions to your queries.
