 ## Header Bidding
 
-### What is header bidding?
+### What is Header Bidding?
 
-Header bidding is a response to a fragmented and highly inefficient process for digital ad display. It is an alternative to the "waterfall" method, the process of offering impressions in one sales channel and if that does not succeed moving to less valuable channels. Header bidding is sometimes referred to as advance bidding or pre-bidding.
-When the page loads, header bidding enables publishers to have simultaneous auctions with all SSPs and ad exchanges. Publishers can receive bids on their inventory that may be unavailable through their primary ad server and exchange.
+Header bidding is a response to a fragmented and inefficient process for digital ad display. It is an alternative to the "waterfall" method, in which impressions impressions are offered to one sales channel at a time, moving down an inflexible stack of sources.
+With header bidding, the publisher creates a short delay in their ad serving to obtain bids from many SSPs and ad exchanges. In this way, publishers can receive high value bids on their inventory that may be unavailable through their primary ad server and exchange.
 The returned bids are then passed into the ad server so they can compete with direct demand and the primary ad server's exchange on a level playing field.

+### A Brief History of Header Bidding
 
-The early days of header bidding were dominated by bad practices, closed proprietary tech, poor standards, and little to no cooperation between competing companies. Publishers were presented with the confusing and time-consuming process of having to manually patch together various solutions from different companies and processes.

Publishers were presented with the confusing and time-consuming process of having to manually patch together various solutions from different companies and processes.
 Prebid.js launched in 2015 to make header bidding easy for publishers by bringing conformity and simplicity to the header bidding process. By creating a simple, open tech layer upon which companies could add their code to a standard but optimized foundation, Prebid.js made it easier to implement header bidding, and offered the largest repository of working adapters.
-Today, Prebid.js is the most widely used header bidding "container" or "wrapper" on the web. The ecosystem supports more than 150 demand partners, over fifteen analytics providers, and numerous publishers.

 **Reducing Latency**
 
-One of the main problems publishers have experienced with other header bidding solutions is the delay between the bid requests being sent and the responses being returned. Many solutions use synchronous calls, meaning each SSP or ad exchange has to receive the request and return a response before the next SSP is called. This can lead to a long delay between when the web page is called and when it is actually loaded.
-Prebid resolves this issue by concurrently calling the selected SSPs and ad exchanges within the set timeout. That setting is respected by Prebid.js, and any bidder not returning a result within the timeout duration is excluded from the auction. This dramatically decreases the page load time, providing a better user experience.

 4. Prebid passes the winning bid parameters to the ad server as key-values.
 5. The ad server takes those key-values and finds a matching line item and compares to other line items that bid on this impression.

 ### Prebid Server
 
 Prebid Server provides a server-side solution to header bidding. Built on the same core principles as Prebid.js, our server solution can reduce latency and improve page load time.
-Several Prebid.org members provide hosted solutions, enabling publishers to receive the benefits of server-side header bidding without the need to implement and manage the process themselves.
 
-If a publisher would prefer to implement their own solution, [source code](https://github.com/prebid/prebid-server) is available from our Github page and detailed instructions for configuring, deploying and testing your implementation can be found in the [Prebid Server section](/prebid-server/overview/prebid-server-overview.html) of this site.  
+When a pub chooses to push auctions to the server-side, they're doing it to
+lighten the load that header bidding has on the browser. For instance, if 5
+bidders are moved from the client-side to the server-side, the browser just makes
+one request to PBS, which fans out the actual 5 auctions across server-to-server
+connections.

 **Prebid Server process**
 
 Prebid Server (PBS) provides multiple endpoints for auctions as well as data retrieval and supports the AMP (accelerated mobile pages) format. The primary endpoint is `/openrtb2/auction` and the process follows these steps:
 
 1. An OpenRTB request is sent to Prebid Server.
 2. Prebid Server conducts the auction with selected SSPs and ad exchanges.
-3. PBS collects the bids and creatives and stores them in Prebid cache.
-4. PBS passes the winning bid parameters to the ad server.
-5. The ad server takes the passed in key-values and finds a matching line item and then compares to  other line items that bid on this impression.
-6. If the ad server determines Prebid wins the auction it returns a reference to the winning creative to Prebid.
-7. Prebid retrieves the winning creative and displays it in the correct ad slot.
+3. PBS collects the bids and creatives.
