As well as utilising all the main search engines, Spyglass now uses it’s very own link database. It is the ONLY tool in the marketplace to have this functionality.
Think of spyglass as having its very own spider and search engine to dig out links for you.
It currently supports over 160 international and local search engines so you can get backlink data and analyze your competition using the engine that matters most to you – or all of them, if you wish.
Search engines currently supported include Google, Yahoo! and Bing and many of their localized versions, as well as regional ones e.g Yandex, Baidu. or Seznam etc
