Just a quick note since I am getting a lot of questions about hosting and domains....
One of the critical elements of the whole "sales funnel" is the well-working website. And you can't have a fast and reliable site without proper hosting. I've tested a variety of providers over the years, and finally, I settle down for Namecheap - a company based in Phoenix, Arizona.
At this point, they have all my business - domain registrations and multiply hosting accounts. Even if you can probably find more advanced and faster service, their combination of pricing and quality of service is superb.
All hosting companies running through problems here and there, and at the end of the day, reliable customer support is what makes it or breaks it. And that's where Namecheap shines. Their Live Chat is available 24/7, 7 days a week, and I have never wait for more than a few minutes for a friendly agent. And that's how they won my vote. Plus - you can't beat those prices 🙂
