How to Ensure CTWA Ads Only Generate Leads from the Facebook & Instagram Apps

When running Click-to-WhatsApp (CTWA) ads, you might notice that some leads come from people browsing Facebook or Instagram on a web browser (desktop or mobile browser).

👉 The challenge: Browser users often drop off before opening WhatsApp, which reduces lead quality and conversion rates.

👉 The solution: You can set up your Ads Manager so your CTWA ads only show inside the Facebook and Instagram mobile apps — ensuring smoother redirection to WhatsApp and higher-quality leads.

This guide will walk you through the exact steps.

Step 1: Open Your Campaign in Ads Manager

1. Log in to Meta Ads Manager.

2. Go to your CTWA Campaign.

3. At the Ad Set level, scroll down to the Placements section.

Step 2: Select Manual Placements

• By default, Meta chooses Advantage+ Placements (automatic).

• Instead, select Manual Placements so you can choose exactly where your ad should appear.

Step 3: Devices → Choose Mobile Only

This is the critical step you flagged.

• Under Device settings, select Mobile Only.

• If there’s an explicit option for Mobile Web vs Mobile App, make sure Mobile App (or “Mobile only / App only”) is selected and Mobile web is deselected.

• This prevents both desktop and mobile browser users from seeing your ad.

Step 4: Choose the Right Platforms

• Select only Facebook and Instagram.

• Deselect Messenger and Audience Network (these bring in web traffic and third-party apps).
