Hi +Darren Shaw
Aleh here, Rank Tracker's founder.
First of all, thank you for your attention and stepping into the discussion.
It wasn't our intention to state that Rank Tracker is the only to check local rankings now.
On the contrary, the explanatory article that announces the feature gives an overview of all the variety of checking local rankings available on the market ("near" parameter in the URL, "uule" parameter, location emulation in Google Chrome).
However, the solution we came up with in Rank Tracker is unique. It's based on passing the exact GPS coordinates, and is not limited to specific regions of the world (e.g. the US, Canada, the UK, Australia and New Zealand only), restricted to large cities only, and such. In fact, Rank Tracker's local data can be provided even for a particular street address.
With that in mind, we're pretty excited with this solution introduced. However, we do realize other providers have solutions of their own to deliver local ranking data, including the industry-favorite Whitespark Local Rank Tracker, which we have great respect for.
