As straightforward as the term one-page website seems, there is actually more to it than you imagined. The simple explanation is that a one-page website is one that uses a single web page to load all pages dynamically. The website may have a base layout for the main page but different content organization for other pages.
Previously, you would scroll a single page website endlessly as you access the different pages/content parts, but this is being replaced by newer CSS3and AJAX techniques that allow for navigation menus that take you right to that particular spot on the page without scrolling.
The point of a one-page site is to provide just enough information that a user can act upon. The point is to eliminate as much clutter as possible and only focus on the most important content that will attract a user’s attention.
A single page website works best for product announcements and promotions, showcasing a portfolio, and websites that generally have little content.
Now that we have an idea of what a single page website is, let’s take a look at its benefits.
In web design, if you achieve more with little it means you have created simplicity. That’s precisely what single page websites or themes are all about. For instance there’s no need to direct users to certain pages. There’s no need for gigantic navigations.
Slightly Faster Browsing
Since the different parts of the website are located on the same page, it provides for faster browsing. Users simply scroll or click menus and instantly jump to the appropriate section. This doesn’t affect performance but it makes browsing the site easier for site visitors.
Focus on Quality
A single page website focuses on quality rather than quantity. Since you can only scroll down on a single site page, you are forced to simplify your message. In other words you only put there what matters. This is partly why single page sites work best for conversion purposes.
Higher Conversion Rates
Users typically scroll down on a single page website to read more content. You can carefully plan the sequence of page elements that your web visitors see and ultimately lead them to the action you want them to take. Unsurprisingly, many landing pages nowadays use a single-page design.
Easier To Manage
As already mentioned, single page websites generally contain less content compared full websites, so there is less content to maintain. Moreover, it’s only a single page to take care of and this makes life a lot easier.
Slightly Improved SEO
This particularly applies to Google: your PageRank will be applied to the entire website since it is a single page. Note that these SEO benefits apply if the website is dedicated to a single product.
