But not everyone wants that.
Steve Love has never had a website for the handmade sausage and meat business he's owned since 1988. He says a website for LoveLand Farms would boost sales and he doesn't have any more farmland to raise hogs and Black Angus cattle.
"I don't want it to grow," says Love, who sells his goods at a farmers' market in Bloomington, Indiana, and a store in another town that's open once a week. "I'm already maxed out. I'm scared it would blow up on me."
But customers expect one. When they ask him at the farmers' market if he has a website, he hands them a card with his phone number and a map to his shop called the Sausage Shack in Nashville, Indiana. He has no plans to start a website anytime soon. But it could happen in the future if his kids want to take over and grow the business.
"I wouldn't say never," says Love.
Some owners simply say they have no time.
Bill Peatman, who writes blog posts, emails and other content for websites for his corporate clients, doesn't have one for his own business.
"I've just been too busy," says Peatman, who started his Napa, California, business over a year ago. "I haven't come up with a plan with what I want to do."
He knows he needs one. "People don't think you exist," he says. "I want to grow. I want to build my own reputation and brand."
He recently bought a domain name. And he plans to hire someone to build the site, but he thinks it will take him a few more months to get to it.
"At the way I move," says Peatman, "about six months."
Fifty-five percent of small businesses don't have a website, according to a 2013 survey of more than 3,800 small businesses conducted by Internet search company Google and research company Ipsos. That's a slight improvement from the year before, when 58 percent said they didn't have a website.
Small business owners who want to start a website have lots of options that make it easier than in the past. Companies such as Wix.com, Google, SquareSpace.com and Weebly.com require no coding or technical skills. Users can choose a template, drag in photos and paste in words.
And with more people searching for businesses online and on their smartphones, companies without a site may be missing out on extra business.
"You might as well be a ghost," says Blasingame, who hosts "The Small Business Advocate," an online and nationally syndicated radio show. "The customers and opportunity pass right through you."
