My campaign funnel

That's not much of a funnel. I wouldn't call it a funnel at all - it's just a salespage - but i guess that could technically be debated.

First, I hope you're not using a free weebly site with a weebly address. You didn't specify if you were using a paid weebly plan with your own domain and no weebly branding. If you don't have your own domain, you need to get one before you do anything else.

I'm sure you've already read many times about the value of email marketing and capturing your leads. No one can force you to do it, but if you're going to spend money on ads, you should ask yourself why you wouldn't want to. There are a variety of ways to go about it and you can still send people directly to your salespage while giving them the option to get on your list. Even if you choose not to use email, a funnel usually involves selling something else after the initial sale, which you have no mechanism in place to do. You aren't collecting their email and you have no upsells so if you do get someone to buy, they are then gone forever after that one sale.

You should decide whether you want to get serious about this or not. From your post, it seems like you're just playing around right now honestly. If you want to have a business and you're going to take that business seriously, you need to put a lot more work into this. First, it requires a lot more thought than you've clearly put into it. You need to come up with a plan for an actual funnel and then work to make it a good funnel at each step along the way. You also need to learn to use the tools you are going to use to make the funnel, unless you plan to outsource it. (I recommend learning it yourself even if you do outsource). You shouldn't even be thinking about running ads yet.
