Working with Yandex.Direct ad block code

You can enable the additional functions and change certain settings by directly editing the ad code without using the code designer in the interface.

The Ya.Context.AdvManager.render function is responsible for invoking the ad in the code.

Attention. If you do not have sufficient experience working with ad code, it's not a good idea to make your own changes to the ad block code. Any changes to the variables and functions other than those described on this page might lead to errors in the Yandex Advertising Network ad blocks and cause you to lose revenue.

  3. Container size for an adaptive ad block

The callback function that is invoked after ad rendering

The onRender Callback function allows you to obtain information about whether the ad has been rendered (whether the ad was successfully selected when requested from the RTB system) and which particular ad was shown. The function obtains the data.product parameter with one of two values:

  • direct — Yandex.Direct ads were shown in an RTB ad block.

  • rtb — A media ad was shown in an RTB ad block.

The onRender callback function must be added as the last parameter in the Ya.Context.AdvManager.render function. The function can only be used in asynchronous code for invoking the ad.

An example of asynchronous code that is used to invoke an ad with the onRender function
function renderRtb () {
    Ya.Context.AdvManager.render({
        blockId: "R-A-12345-1",
        renderTo: 'rtb',
        async: true,
        onRender: function(data) {
            console.log(data.product);
        }
    });
};

(function(w, d, n, s, t) {
    w[n] = w[n] || [];
    w[n].push(renderRtb);
    t = d.getElementsByTagName("script")[0];
    s = d.createElement("script");
    s.type = "text/javascript";
    s.src = "http://an.yandex.ru/system/context.js";
    s.async = true;
    t.parentNode.insertBefore(s, t);
})(this, this.document, "yandexContextAsyncCallbacks");

Ad impressions in infinite scroll feeds

To display ads in infinite scroll feeds, you can use the same ad block and just change the pageNumber parameter and the name of the renderTo container. The unique blockId from the code designer remains unchanged.

Example of the ad code for the first ad block
<div id="yandex_rtb_1"></div>
<script type="text/javascript">
    (function(w, d, n, s, t) {
        w[n] = w[n] || [];
        w[n].push(function() {
            Ya.Context.AdvManager.render({
                blockId: "R-A-12345-1",
                renderTo: "yandex_rtb_1",
                async: true,
                pageNumber: 1
            });
        });
        t = d.getElementsByTagName("script")[0];
        s = d.createElement("script");
        s.type = "text/javascript";
        s.src = "//an.yandex.ru/system/context.js";
        s.async = true;
        t.parentNode.insertBefore(s, t);
    })(this, this.document, "yandexContextAsyncCallbacks");
</script>
Example of the ad code for the second ad block
<div id="yandex_rtb_2"></div>
<script type="text/javascript">
    (function(w, d, n, s, t) {
        w[n] = w[n] || [];
        w[n].push(function() {
            Ya.Context.AdvManager.render({
                blockId: "R-A-12345-1",
                renderTo: "yandex_rtb_2",
                async: true,
                pageNumber: 2
            });
        });
        t = d.getElementsByTagName("script")[0];
        s = d.createElement("script");
        s.type = "text/javascript";
        s.src = "//an.yandex.ru/system/context.js";
        s.async = true;
        t.parentNode.insertBefore(s, t);
    })(this, this.document, "yandexContextAsyncCallbacks");
</script>

Container size for an adaptive ad block

The adaptive ad block adapts to the size of the container and is suitable for sites with an adaptive layout. Use stylesheets to specify the container size for sites with an adaptive layout.

  1. Add the tag div CSS classyandex-adaptive in the ad code that you obtained in the interface.

    Example
    <div id="yandex_direct_R-A-12345-1" class="yandex-adaptive"></div>

  2. Use media-queries to configure the container to accept various sizes depending on the screen resolution.

    Example
    @media screen and (max-width: 800px) {
    .yandex-adaptive {
        width:200px;
        height:300px;
    }
}

@media screen and (max-width: 1024px) {
    .yandex-adaptive {
        width:240px;
        height:400px;
    }
}

    So ads will be displayed in a 200×300 block on screens that are up to 800 pixels wide, and in a 240×400 block on screens that are between 800 and 1024 pixels wide. If the screen is more than 1024 pixels wide, then the ad block will use the dimensions specified in the interface.

Note. If you want the container to always use the same size, specify it in the visual code designer in the interface.
