While adding Search Engines of a new project, select Google Locals from the dropdown. This will track Google Maps for the keywords you have added and whether your domain is being ranked as well.
On top of Organic results, RankWatch also displays local results on its Ranking Overview Page under the section, Additional Rank. Besides Organic results, this section tracks the SERP for Videos, Images, Ads, News and Local Results.
We not only track your rakings in Google Locals but also track how many local listings are being displayed on Google Search Page for your keyword.
