Leads, leads, where are my leads? The life of your small business is leads. Without leads (potential customers) who know about and want your product or service, your business is just an expensive hobby.
As a small business owner, if you have a limited budget, keep a watchful eye on how much you spend on each marketing activity.
Also track how effective each activity is to keep costs under control and to find the winners.
