Key/Value Pairs is a targeting feature that allows publishers to use custom metadata on their sites to deliver direct sold campaigns.

Example case study on a publisher's successful use of Key/Value Pairs.

Getting Started

Using key/value targeting requires a two step set up on Nativo Admin and publisher’s website.

Define key/value pairs on Nativo Admin

  1. Sign in on Nativo Admin.

  2. Navigate to Monetization tab and click Key-Values.

  3. Click Create Key.

  4. Add a key name.
    Key name cannot contain spaces and cannot be prefixed with a number.
    ​Read more limitations on characters allowed.

  5. Add a display name.

  6. Check the Allow Free-Form Values box to allow additional values to be added for targeting at Budget level.
    ​Read more details on Free-Form values.

  7. Click Create.

  8. Add corresponding values under Values input box on the next page.
    Value format restrictions include a max of 40 characters per value, a max of 20,000 active values per key. Read more limitations on characters allowed.

  9. Click Save.

Adding multiple values by uploading a file

  1. On the Edit Key page, click on Upload File radio button.

  2. Select CSV file and it will be uploaded automatically.
    Accepted file format is a single column CSV file with no header.

Define key/value attribute on publisher website

Setting key/value attribute on publisher’s website is supported by HTML meta tag and JavaScript tag.

HTML meta tag

Key/value attribute may be set on HTML meta tag with custom metadata name ntv-kv. One or more tags can be placed in a single HTML page to define multiple key-value attributes.

Each tag should contain a key and its corresponding values. Multiple values separated by a comma is supported per key.

HTML

<!-- One Key One Value --> <meta name="ntv-kv" key="name" values="value1"> <!-- One Key Multiple Values --> <meta name="ntv-kv" key="name" values="value1,value2,value3,value4"> <!-- Multiple Keys One Value Per Key --> <meta name="ntv-kv" key="name_a" values="value"> <meta name="ntv-kv" key="name_b" values="value"> <!-- Multiple Keys Multiple Values Per Key --> <meta name="ntv-kv" key="name_a" values="value1,value2,value3,value4"> <meta name="ntv-kv" key="name_b" values="value5,value6,value7,value8">

🚧

The HTML meta tag should be rendered before Nativo’s load.js is executed.

JavaScript Implementation

Key/value attribute may be set in the JavaScript object ntvConfig under keyValues property. One or more keys can be placed in a single HTML page to define multiple key-value attributes.

JavaScript

// Initiate an empty object var kvpMap = {}; // To set one key one value pair kvpMap["name1"]= "value1"; // To set one key, multiple values pair kvpMap["name2"]= "value2,value3,value4"; // define "ntvConfig" object if it is not already defined window.ntvConfig = window.ntvConfig || {} ; // Assign the defined key value pairs to "keyValues" property window.ntvConfig.keyValues=kvpMap;

🚧

The JavaScript code should be executed before Nativo’s load.js is loaded.

Limitations

Characters

There is a maximum of 20 characters per key and a maximum of 40 characters per value. Both keys and values are not case-sensitive. Key cannot be a prefixed number and cannot contain spaces.

Publisher can choose to set as many key-value attribute on the page as they like.

However, the number of key/value sent to Nativo’s adserver is limited to the browser’s URL character limit for GET requests. A common restriction is 2,048 characters, minus the number of characters in hostname and path.

Following characters are not allowed on key and value;

" (double quotes) ' (apostrophe) = (equal sign) ! (exclamation point) + (plus sign) # (pound sign) * (asterisk) ~ (tilde) ; (semicolon) ^ (caret) () (parentheses) < > (angle brackets) [ ] (square brackets) , (comma) & (ampersand)

PII

Publishers are responsible to restrict PII (personal identifiable information) from being sent to Nativo.

Predefined and free-form key/values

Predefine a key and its values or create a free-form key-value. Free-form key-values use a defined key but take dynamic values based on user attributes or behavior.

Predefined key/values

Use predefined key/values when you know the possible range of values. For example, if you're targeting a budget to users age 18-34, create the predefined key age, and enter ranges as values (such as, "18-34" or "35-49"). When you create the budget, select age as the key and "18-34" as the value. When you target a budget to a predefined key-value, you choose from a list of values in defined in the Nativo Admin. When a value is removed, it no longer appears as a targeting option.

Free-form key/values

Free-form key/values let you pass targeting values dynamically based on information you collect. For example, you can use free-form key/values to target ads based on DMP audience information on your site.
