Nurturing a lead involves careful and consistent communication with the lead, as you try and convert them into your customer. If you’re in SaaS, the problem statement could look like this: somebody just signed up for my product, so 30 days from now, how do I get them to sign on the dotted line? You use a tool like email. Well-compiled emails, sent at regular (but unobtrusive) intervals, have a very good chance of gaining your reader’s mindshare and making them invested in your product. With each interaction, you take a step towards bringing the lead closer to your business.
Lead generation is the process of finding people (leads) who’re likely to become your customers immediately or in the future. “Finding” people implies finding information about people, like their name, email ID or organization’s name, all of which you can use to initiate a business relationship with them. You can generate leads organically and/or by spending money, depending on your resources.

Pay-Per-Click (PPC) advertising is one of the easiest and most cost-effective ways to generate leads online. Available through popular programs like Google AdWords, Microsoft’s Bing Ads, and Facebook Ads, PPC is exactly what it sounds like: an advertising program in which you pay for each click. Depending on the keywords or phrases targeted, you may pay anywhere from pennies to hundreds of dollars for a single click.

Over the years, businesses have used many tools for lead management, like the rolodex, contact management software and spreadsheets. But these tools function like a system of record. Sales reps just view their leads using these tools; they don’t get context. And that’s where CRM software (customer relationship management software) fills the void. In a CRM, every lead gets their own profile. This profile contains demographic details, a chronological list of every conversation the lead has had with your business, along with all the data/documents you’ve ever shared with them. And all this is just one part of what CRM software can do.
Lead generation often uses digital channels, and has been undergoing substantial changes in recent years from the rise of new online and social techniques. In particular, the abundance of information readily available online has led to the rise of the “self-directed buyer” and the emergence of new techniques to develop and qualify potential leads before passing them to sales.
Unfortunately, there’s no "magic bullet" that can make your website a magnet for prospective buyers, or convince every potential customers that you’re the right choice. Instead, you’ll want to use a combination of lead generation ideas and tools to establish, nurture, and grow relationships with potential buyers -- which will ultimately lead to something substantial and long-term.
Cost per click advertising (e.g. AdWords, Yahoo! Search Marketing) overcomes this problem by charging advertisers only when the consumer clicks on the advertisement. However, due to increased competition, search keywords have become very expensive. A 2007 Doubleclick Performics Search trends report shows that there were nearly six times as many keywords with a cost per click (CPC) of more than $1 in January 2007 than the prior year. The cost per keyword increased by 33% and the cost per click rose by as much as 55%.
