It can work it's just harder. If you're looking to advertise and you have a limited budget I would suggest Google search ads. Honestly though with limited budget you're likely better suited to doing some combination of PR + SEO + Content marketing and using the cash you would have spent on ads to enhance those efforts. Once you've got your funnel figured out then you can expand into paid advertising.
