Usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some ISPs actively attempt to block home servers by disallowing incoming requests to TCP port 80 of the user's connection and by refusing to provide static IP addresses. A common way to attain a reliable DNS host name is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.
Responsive design is a popular web design strategy used by some of these site builders. This approach reformats the same webpage content to fit different screens. But in terms of SEO (search engine optimization), the search engines only care about whether a site displays suitably on mobile screen sizes. Both Bing and Google have pages where you can enter your URL to see if your site plays on mobile acceptably.
By creating a website, you are creating an online presence. This allows you to connect with people that you might not otherwise be able to reach. Whether you’re making a basic website with contact information for your small business or medical practice, creating a landing page for your freelance work, a multi-page experience for your wedding photography business or you just want a place to blog about your thoughts on food, having a website will give you a dynamic advantage.
