Nice one ruicarlov!
In my opinion matrices are ok as long as they are not the main product a site has to offer.
A matrix can be a successful technique to promote some other product, item or service.
etc. if I wanted to sell an ebook I would use a matrix-like system to sell it.
If its price is $10, I would keep $4 as a standard fee and then offer $3, $2, $1 accordingly to 3 upline tiers..
So if I refer A, A refers B, B refers C, C refers D and D refers E this will have made me 5 sales = $50 (of course that's not profit).
Here's how much each one would have earned from each one's purchase :
Me = $10 from A, $7 from B, $5 from C, $4 from D, $4 from E = $30 total
A = $3 from B, $2 from C, $1 from D = $6 total
B = $3 from C, $2 from D, $1 from E = $6 total
C = $3 from D, $2 from E = $5 total
D = $3 from E = $3 total
E = No sales..
The point is that the reason to make the purchase for someone should be the actual ebook.
It will be profitable for whoever wants to promote, but not everyone would want that. Some will
actually just buy the ebook and forget about it. What I'm trying to say is that matrix should not
be used like a program.. but only like an affiliate marketing tool. Otherwise people might not be
interested enough to make the purchase and the system will not work.
The same goes to PTCs.. a PTC ad pack must be something interesting for an advertiser to purchase.
Otherwise an advertiser won't purchase it and members won't have what to click on so the whole system will fail.
Offering non-incentive advertising within each PTC pack should be a must for PTC sites in my opinion.
I believe it's what saved neo (not the matrix one..lol) from drowning..
That ad grid idea was perfect to help with this. That's how he can sell 2500 actual clicks at the price of $5,
so he's able to offer up to $0.02 / click, just by packing a free additional 2500 clicks from ad grid..
Keep in mind I'm talking about micro ads here, meaning there's no earnings for uplines.
Edited: Now that I think of it actually the profit from micro ads sales is much bigger..
2500 x $0.001 = $2.5 for any membership type! So from each micro ad sale neobux keeps 50%
Standard Ads cost are different of course : 250 clicks for $5 which equals to $0.02
This is the expense neo will have to pay at the worst case scenario : Upgraded upline + Upgraded downline = $0.01 + $0.01 = $0.02
and this is why it's 100% stable. The ad grid bonus is just to make the advertising more appealing.
