My advertising is all - website and word of mouth. Mostly website. My truck is lettered but that's hasn't gotten me anything in over ten years in two different businesses. Mainly it's to satisfy IRS requirements to show exclusive business usage. Cards get passed out to customers to pass along and hopefully keep for reference. But just having a website wont get you any business. It has to be on the first two pages of the search engine the potential customer is using. That's why "do-it-yourself" websites are useless.
