This is typically manifested in the form of wayfinding information in places such as streets or on the inside and outside of buildings. Signs vary in form and size based on location and intent, from more expansive banners, billboards, and murals, to smallerstreet signs, street name signs, sandwich boards and lawn signs. Newer signs may also use digital or electronic displays. The main purpose of signs is to communicate, to convey information such that the receiver may make cognitive decisions based on the information provided. In general, signs may be classified according to the following functions.
The first type of relationship between a website and an advertiser was a straightforward, direct partnership. This partnership model implies that the advertiser promoting a product or service pays the website (also known as a publisher) directly for a certain amount of ad impressions. As time went on, publishers began creating thousands of websites, leading to millions of pages with unsold ad space. This gave rise to a new set of companies called Ad Networks. The ad network acted as a broker, buying unsold ad space from multiple publishers and packaged them into audiences to be sold to advertisers. This second wave of advertiser-publisher relationships rapidly gained popularity as it was convenient and useful for buyers who often found themselves paying a lower price yet receiving enhanced targeting capabilities through ad networks.
The third and most recent major development that shaped the advertiser-publisher ecosystem started occurring in the late 2000s when widespread adoption of RTB (real time bidding) technology took place. Also referred to as programmatic bidding, RTB allowed companies representing buyers and sellers to bid on the price to show an ad to a user every time a banner ad is loading. When a page loads during a user visit, there are thousands of bids occurring from advertisers to serve an ad to that user, based on each company’s individual algorithms. With this most recent change in the industry, more and more ads are being sold on a single-impression basis, as opposed to in bulk purchases.
