There are a few issues with Similar web API for content matching. It is domain level or app level category. That is not granular enough. It is not generic, too. To be granular, you need to go down to content level. For example, for ecommerce site, you need to know when a user searches Nikon camera or baby diaper. For another example, for a news app, you need to know when a user reads about Taylor Swift or "The Uber Model, It Turns Out, Doesn't Translate". To be generic, you need to go down to content level. For example, Nikon camera can be searched in an ecommerce site or in a native app. You only need to match ad with Nikon camera. That means by focusing on content, your technology works for both Web and in-app. Our technologies focus on content. It takes free texts, product names or barcodes (UPC, EAN and ISBN), returns their IAB category, product category, etc. You can go to (http://compariola.com/AdSmart/TestAd) to test drive. We do have service available for content matching. Please let me know if you would like to know more. Thanks, Gary
