Making sure you include contact details on a business site is a basic lesson everyone should know. But there's another important detail service professionals should include but often don't — how far they are willing to travel to do work.
Google's Australian blog reminds us of that point in a post examining steps businesses can take to improve web site content:
If you travel to your customers — like carpet cleaners or massage specialists or pest control specialists do — be clear about how far you’re willing to travel. Do you only service clients within the city limits? If you deliver, what’s your delivery area? Consider listing a neighborhood, postcode, or street boundaries.
Many sites shamelessly include the names of every suburb or town they can think of to improve their appearance in search results, but that ultimately offers no service to customers. I know I'm more likely to contact a business if I'm confident they won't have to drive from the other side of town to offer me a quote.
