Xpidy is a single page responsive website design. A single page website with good SEO ranking was a real challenge for us when we started planning a single page website. We did lots of RnDs and came up with a solution with History.pushstate for HTML5 browsers. The trick is to load the entire page at once and as users scroll down the page, the URL and page title change depending upon the page section they are in. We also provided fallback plan for older browsers. The website is also responsive so that we don't loose visitors and business.
