Which Hosting I should Choose?

I've never heard of FastComet, will have to look them up. Something to keep in mind is loading speed. If you're going to drive a lot of traffic, you'll probably want a VPS.

Re landing pages, you can do whatever you have the time and skillset to do, there are so many options:

• code your own lander
• buy a template
• use a hosted service like Instapage, Unbounce, LeadPages
• self-hosted pages using an online template/editor site (i.e. PureLander but you can do a Google search to find more)
  
• wysiwyg software like Kompozer (self-hosted pages)
• use a WordPress plugin
• use the landing page feature in your autoresponder (assuming it's an option)
• hire someone to build it custom for you
• combine tracking and landing page, i.e. AdsBridge

 

They're not mistakes, they are learning opportunities. You WILL make mistakes along the way, all part of the learning curve. And any time you need help, just let us know.
