VigLink

VigLink is a San Francisco-based, outbound-traffic monetization service for publishers, forums, and bloggers. VigLink specializes in in-text advertising and marketing. VigLink CEO Oliver Roup founded the company in March 2009. 
In 2012, Oliver Roup reported VigLink was working on 5 billion pages per month.
As of November 2014, VigLink has raised $27.34 million and is working with 63,000 online retailers including EBay, Target, Amazon.com, and Wal-Mart.
VigLink’s content monetization solution connects potential consumers to products by hyperlinking particular keywords in a website’s content. The company’s technology, VigLink Insert, scans a page for words that could be potentially profitable to the publisher of the page, and connects the keyword with a product from an affiliate program. The publisher is paid when a reader clicks a link contained in the content to buy or learn more about a service or product.
VigLink also offers an outbound analytics service for clients to understand where readers go when they leave their site.
