Appstractor Supports Local SEO by Unlocking Closed Data from Apps

What local problem(s) does Appstractor solve? How?

Using our geo-proxy servers, you can surf as if in another country or US metro area, to see local web content, display ads and search results as they really appear. Our new experimental product, MobileHorizons, is like a keyword ranking tool intended to show clients’ rankings inside third party mobile search apps (e.g. Google Maps, Apple Maps, Yelp etc). Via the Appstractor API, you can incorporate the same data into your own software tool.
