Thanks for everyone that helped.
I created an account on eHost.com, but I really don't know what to do in order to transfer my site to this new host.
I searched here what are the steps for doing so, but find nothing.
Somone here did it before, and can show me the steps that need to be done?

Thanks.

You need to backup your site and make arrangements to host it elsewhere. 30 days after your membership ends it will be deleted.

To make a copy of your website. Go to dashboard and export tick to copy both the content and media. This does not always collect all your images, unfortunately. The best way to collect images is to physically save an image to a file every time you make a post. If you haven't done that then you're going to have to copy every image manually.

When you come to reinstate your site at another host you install WordPress and then import your site.

You can just move your site to an other host. The part with WordPress i don't really get it. But if you cancel WA it doesn't mean you have to lose your site.

It's not too clear. Appears some sort of menu and linkage tweaking is necessary!

I assume you mean the Snippet. That's easy, you just need to follow basic SEO Guidelines.
What I mean by this is, have multiple pages that clearly describe your niche or what your website is all about, have a clear main menu, and each page should be fully optimized for SEO, meaning, have a relevant, focused-keyword title, meta description (those you can do with the plugin all-in-one SEO "behind the scenes"), and of course, relevant content.
With time, google will catch up with your website and when you gain rankings like kyle's site, google will display it that way. Again, it's all about SEO good practice.

To add links to the sidebar,
1. Copy the link
2. On your dashboard click to appearance then to widgets
3. You will see the main and left menu.
4. On the main menu click to Text bar and drug it to the left menu.
5. Click on it to add title.
6. On text mode paste your link under the the text.
7. Save changes and view your page.

Let me know if it works right for you.

I wouldn't toy around with PPC if I'm still a beginner to all this.

First, watch Kyle's video about PPC, that is mandatory.

Then, I'd make sure that the landing page that you're sending your clients to looks clean, optimized, and have good content.

Make sure the product have a high commission because you don't want to spend all that amount of money for a 5$ only commission return.

I would start with binge because they are much cheaper than google.

Other than that, it's just trial and error until you find the perfect landing page with the perfect keywords that generate the most return for you.

I don't know yet but it looks promising.........Scotty B ♫
