I could pay up to 30% of the money i made with the site, you rank.
If i make 10K due to the good site, and good keywords, then why not pay you 3K/mo? And even 5k.mo?
I said up 30% because usually a site has other expenses like money for content and design, and taxes you need to pay.
But its not all about money one can pay.
Sadly its allot different story.
Its more about the trust, I believe.
First thing first I don't know you, nigher you know me. You see I am new to BHW with only a few posts, right? Are you willing to pay you when the site is ranked for the given keyword? I don't think so. Most probably you will ask for money in advance. But how can I pay you if i dont know you, your business, and SEO at all? We need to use an escrow service.
Second it comes to conversions. Yeah, my site is new and i don't know how it will convert. I want to make 100 sales/mo = 10k if you rank the site for weight loss. But will it make it? I doubt unless i know what i am doing. But ... how can i promise i will pay you 3k/mo if the site is nowhere in SERP and I don't have a clue if it will make a sale/mo or not?
All in all its a difficult game.
If you offer the best SEO service ever, why dont you use it on your own websites? Yeah, i know, why.
So lets make it easy.
You have a service, I have money. Whats is your offer?
Can you guarantee top G ranking?
