What is Facebook Dynamic Language Optimization?

Get Started Now to Optimize Your Ad Campaigns

If your brand has an international audience, one challenge can be serving ads in the user’s primary language. That challenge is significantly reduced with the availability of Facebook’s Dynamic Language Optimization (DLO).


What is Dynamic Language Optimization?

Until now, advertising to a universal audience meant one of two things: a) Lots of manual work or b) Ignore it and focus on a single language.

To account for multiple languages, you’d need to create multiple ad sets — one for each language. You’d then create a separate ad for each ad set. You’d go through the typical process of providing a link, thumbnail image, headline, text, link description, and call-to-action button for each ad.

But, with Dynamic Language Optimization, you can use one ad set and one ad with up to six language variations. It’s easy then to A|B Test your creative in multiple languages because Facebook automatically optimizes to show the right language variation of the ad to the right people. By running DLO, Facebook has control over which creative is served. In addition, they can quickly optimize a high volume of creative combinations versus just running many ads per ad set.

There are two primary examples of when this would come in handy:

1) Advertising to a single country that is dominated by two or more languages

2) Advertising to multiple countries at a time


Benefits – DLO makes it easy to:

Previously, in order to target different languages, each campaign would have to be split up into numerous language-specific and target location ad sets.

With this new feature, however, advertisers are able to load up multiple language variations of the same ad. In addition, Facebook will dynamically show the ad in the relevant language for each user.

Thinking outside of Facebook campaigns for a moment, for certain regions in the world, it’s not always obvious which language to prioritize for your marketing activities. If that’s the case, then this is a very efficient and quick way to find out.

Thankfully it’s remarkably easy to set up a test and get things going, as long as your campaign goals match those currently available with the DLO.

Getting Started with Dynamic Language Optimization

You can access DLO via the Ads Manager. Firstly, you must set up a Traffic, Mobile App Install, or Conversion campaign. If you want to drive any other objective, the option for Dynamic Language Optimization will not currently appear.

You may wish to optimize ads to show in numerous languages for multiple countries. Yet here lies a complication: you can only currently set up one ad set for each country. Within each location, however, six languages can be applied.

Ad Placements

Your next step is to edit your placements as there are restrictions here too. Your ads can only appear on Instagram, Facebook Newsfeed and right-hand side, or Audience Network. Finally, you can move on to design your ad.

The ad itself must be a single image because this option cannot be applied to carousel ads yet. But hopefully, that will come in time. From here, you select a default language which will also be the language you see in all of your previews.

The image will remain the same, so remember to ensure that you don’t use something with text on it. At this stage, you can enter the text that each user will see for the headline and text. And also for the newsfeed link description and the destination URL. You can then direct users to language-specific versions of your web pages.

Ad Testing

Once this is done, you are ready to start testing! Also, because you are using a dynamic ad set, you can only have one ad in each.

The different versions can now be seen and edited in Power Editor. Meaning you can continue with your normal workflow if Power Editor is your preferred way of working. However, if you are sending previews to clients to approve, they will only be able to view the default language version using the preview link.

For reporting data, assuming you are testing the efficacy of creating DLO ads, then simply select the ad set and click on Breakdown and Asset Type (ex. a single image or video). You can compare CTR and CPC, and then validate your campaigns.
