Display advertising is one of the most common ways to monetize a blog.
It’s simple, easy to get started with, and can be very profitable.
Traditionally, site owners used to have to go out and find advertisers directly.
They would have to do everything manually from negotiating deals, signing the agreements, collecting the fees, and putting up the ad.
This takes a ton of time and work to put together.
Advertisers can churn quickly, and you’ll end up spending dozens of hours each month doing outreach and trying to sell ad spots.
For most site owners, display ad networks are the better option.
An ad network is a platform that serves as a broker between a group of publishers and a group of advertisers.
Traditionally, the ad networks role is to collect unsold inventory from multiple publishers, then offer this pool of unsold inventory to advertisers at a much lower price than a publisher’s direct quote.
This made it so the ads weren’t great quality. They were referred to as non-premium.
Today, more networks aim at offering their advertisers exclusive deals at premium prices.
They sift through and pre-buy inventory from a number of top-tier publishers, then resell it at premium prices.
Although this arrangement may be more expensive for everyone, it insures premium placement of their ads to make the most money.
