@Drew Can you elaborate on how this will work for Pros that already have an established presence as a Local Business? Will the listing be competing with Local Business listing that organically comes up in search (not a paid ad)?
And how will these ads represent Pros? Will the ads rotate between individual Pros at different time?
Google Local Services certainly does not support all of the categories that TT does so the blog post is leaving out some critical points. Also, @RCPS brings up a great point in that many of the pros here are already on GLS and it will be needed to know how conflicts are resolved.
Also, I will add that GLS is not available in all areas of the country. Does this offering expand the geography presence?
