If you're focusing on inbound techniques like SEO, social media, and content creation for a preexisting website, the good news is you don't need very much budget at all. With inbound marketing, the main focus is on creating high quality content that your audience will want to consume, which unless you're planning to outsource the work, the only investment you'll need is your time.
In this scenario, you’re asking people to take little steps, instead of going right from “mailing list sign up” to “spend $1000”. Downloading a free ebook isn’t a big step. Once you’ve done that, sure, why not share? Hey, if the info was valuable in the free book, the info in a $19 book is probably great! Oh, there’s a $197 program? Yes, I would love to join, because I already got more than that much value from your lower-cost items. Spend $1000? Sure!
The first step of any sales funnel is to make a potential customer aware that you exist. You can go about doing this in several ways, such as social media marketing, email marketing, cold calling, attending events, advertising, and word of mouth. How you make people aware of your company really depends on the product or service you’re selling. For example, if you design apps, mobile marketing will probably be extremely effective, but if you sell lawn mowers, this may not be the best option; traditional radio advertising may work better.
Prospecting and marketing are all the things you do to get people into the first of your sales funnel stages. Note that stages are broken into two or more steps wherever possible. A demo could be called a single stage, but in real life it involves a lot of things: contacting the customer, sending reminders, doing the demo, and then following up. Whatever your own sales stages look like, the support you need in managing them will be the same.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
