Apple Search Ads is continuing its expansion into new geographic segments, following a successful rollout to Brazil earlier this year.

Starting today, developers can start buying Apple Search Ads for placement in Turkey, and 20 additional countries.

As a reminder, there are four types of Search Ads that appear inside the App Store app. You have ads that are shown on the Today tab, ads shown on the Search page before the user enters a query, ads at the top of search results, and ads at the bottom of product pages of other apps.

Apple says Search Ads helps developers deliver up to 2x as many impressions as organic search, with small developers benefiting the most. Search Ads works on a cost-per-tap model, so developers pay only when a user clicks on an ad.

Today’s expansion brings the reach of Search Ads to a total of 91 countries. Here’s the full list of new countries available today:

• Turkey
• Algeria
• Mongolia
• Morocco
• Slovakia
• Uzbekistan
• Bulgaria
• Ghana
• Bahrain
• Iraq
• Cyprus
• Armenia
• Luxembourg
• Nepal
• Sri Lanka
• Latvia
• Slovenia
• Estonia
• Kyrgyzstan
• Kenya
• Iceland

Developers in these markets may have previously signed up to Search Ads to begin campaigns that were displayed internationally. But now, they can target customers in their domestic regions as well.

When search ads first rolled out to app product pages, two years ago, there was significant community pushback as low-quality gambling and casino adverts were being shown next to unrelated, professional indie software. At the time, Apple responded by “pausing” the placement of certain categories of ads, like gambling, from appearing in those slots. This policy continues, and is documented here; Apple tabulates which categories of ads are restricted from showing in these ad slots.
