You can make the ads UK specific, plus add a Radius as well, to help better target the ads.
It is something to play with and won't cost much to setup... except for Time. Time is of course something you may not have much of given work and family circumstances.
When I did it, I got more hits on my website but no conversions (no paying customers). So to me it was a waste of Time.
You are even more geographically limited than I am, as you only provide childcare from a fixed location... so your target market is very small geographically.
If I put in Childminder YourVillageName - Google lists you in 1st position.
If I put in childcare YourVillageName - Google lists you in 1st position under Google Places and several times in first page of results (from various websites including your own).
There are very few adwords ads coming up for those searches... so won't be hard to get an ad to appear there. But would having an ad in the Adwords section really make any difference?
Where it MAY make a difference is on Google Content Network, where Adwords ads are displayed on non-google sites, such as on Blogs. Then if someone blogs about childcare or childminders and talks about your part of the country, then I think you ad may show up.
It is hard to know how it will go. I did it and it got me no new business. So give it a try if you like.
NetworkGuy - How can a small business which provides a service at a fixed location benefit best from Adwords? Customers of the business will be mostly from the same village, or a nearby village.
