Ad Codes

📘

Note

For security and page load reasons, we strongly recommend serving ads through Kevel's Decision API.

Overview

Kevel offers four ad code options: Synchronous, Asynchronous, Email, and 3rd Party Ad Server.

Ad Code Options

Standard (Asynchronous) code loads ads independently of the rest of the page, so it won't slow down page loads. It consists of a JavaScript tag plus an HTML div that the JavaScript loads the placement into. When a page loads with asynchronous ad code, the code tells the browser to carry on loading everything else while it waits for the creative from Kevel.

Synchronous code loads on a page the way a page normally does: line by line, waiting for each element. It can potentially slow down page loads, especially if the synchronous code is serving third-party ads that pass impressions from one server to another.

Email code consists of a static link and a static image tag. It can only serve images, not JavaScript/HTML creatives, which means it cannot serve tags from other networks. Only use email code if other options aren't available.

3rd Party Ad Server code is useful if you are serving Kevel ads through another server (such as DFP), or if you need to serve ads to a platform where HTML cannot be used. Note that 3rd Party Ad Server code cannot be used with companion ads or other distribution options.

Ad Code Components

All Standard ad tags contain a comment that explains what the code loads:

/* load placement for account: NetworkName, site: SiteName, size: 160x600 - Wide Skyscraper*/

The ados_add_placement() function loads the actual placement:

ados_add_placement(1613, 15404, "azk57720", 6);

Its four arguments are:

• 1613 is your network ID.
• 15404 is the site ID.
• "azk57720" is the placement name, which Kevel generates randomly. It must match in both the script and the <div>.
• 6 is the adType ID.
