It’s a different ball game when your email list is only real buyers – no “subscribers” you need then to convert to buyers. You can invest more time and money in such a list and get a much better return.
Instead of building a whole mechanism to attract people by creating and promoting content, use existing content that ranks well on the SERPs and advertise directly on (or in) that content.
To accelerate buyers and seller finding each other and the right deal.
Both buyer and seller when going online and advertising or searching a product (their flat, car etc.) will specify not just one price, but 3 prices. The advertised price, the lowest price they might accept, and a price between these two representing what they really would consider an immediate deal price. The system (machine or human) will try and match buyer and seller based on these 3 parameters.
For the merchant, it’s a way to help the buyer design the space he is buying for, while choosing from their offered products. The buyer gets multiple smart designs for his space.
An app or website where you can input the measurements of the space you are trying to design, and get design suggestions complete with shopping list.
