Mobile-friendly (responsive) design means that each and every page automatically adapts or responds to the display size of the device being used to view the page; whether on a desktop, tablet, or phone.
Responsiveness is important for a number of different reasons, but probably one of the most important is that "Starting April 21, 2015, your website's mobile-friendliness will be considered as a Google Search ranking signal (Google)." In essence, non-responsive websites will be demoted in search results depending on the device used to perform the search.
The VO Web Designs website serves as an example of "responsive design" technology in action. To illustrate, try viewing this website on devices with different display sizes. If viewing on a desktop device, grab the outside of the browser window and change it's size. This website's pages will automatically "respond" to the size of the browser window.
Another key to a successful website is search engine visibility. There are many steps that go into ensuring that visitors can find your website. Using key words in the website's page titles, embedding key words about your business within the text, registering your website pages with Google and Bing, search engine follow up; all come into play to help make a website more visible.
