Would it be wise to include your location in the description for location-based services? I figure this would fend off customers who are too sensitive to where the business is located if it's in the description.
Showing the Geo Location on the landing page - it might improve conversion rate for certain keywords. It's something for A/B testing, perhaps combining dynamic text insertion. My guess is that for a certain product you'll have a bunch of keywords for which the "location in the description" will improve the conversion rate. Other keywords will be better off without it.
