Survey your current customers about where they typically congregate online. To generate quality leads, you need to understand where your audience hangs out. Once you know, get involved in that community any way you can. That may mean advertising or it may mean becoming a thought leader in the community. Use customized quality content to generate more leads for you. If a person stays on a page to read what you've written, you're already one step ahead of the game. When people discover value and get the help they need from content, trust usually ensues. This often translates into more sales and sign-ups!
Talk to business owners in related industries. They may be willing to share leads with you, by sending their customers your way. For example, if you own a shop where you sell balloons, talking to a florist about a joint venture is a great way to get leads from another business. Search engine optimization, while organic, is all about lead generation as well. How? Your targeted customer base is searching niche specific keywords. If you're targeting the right keywords with all of your sites and content, then you're generating new leads. This does take time, but it's a process that should always be in the works.
As you can see, lead generation is a necessary aspect of your business. Taking the time to learn about lead generation will pay off in the long run. The more successful you are in applying them, the greater your customer base will become. Start implementing all of these ideas today.
