Dark / Ghost post: when and why to use it? ### __What is a dark post?__ A dark post (Meta or TikTok) is an advertisement created specifically for a campaign and which does not appear publicly on your profile or page. Unlike a classic post, it's invisible to your subscribers your feed, except those directly targeted by the campaign. It's often used to test or target specific audiences without impacting your organic content. ### __When should you use a dark post?__ **To test multiple ad contents (A/B Test):** You can create several variations of a campaign (images, videos, text) and analyze which ones work best without cluttering up your public profile.   **To target specific audiences:** If you want to tailor your message to a specific audience (for example, different age groups or areas), a dark post is ideal.   **To avoid confusion with your organic posts:** If the content of your campaign differs from your usual editorial line, the dark post lets you promote it without making it public on your page.   **For international or multilingual campaigns:** Create country- or language-specific versions without flooding your profile with multiple publications.   **For temporary or specific promotions:** If you're proposing a limited offer or targeting a particular event, the dark post is perfect for targeted, temporary visibility.     ###  __How do I create a dark post with Ctrl+Reach?__ * In the “**Create a campaign**” tab, select the desired objective. ![](https://storage.crisp.chat/users/helpdesk/website/-/7/7/c/6/77c66f5e87ea8c00/capture-decran-2025-07-10-a-16_1boqk0d.png =505xauto) * Configure your targeting and advertising settings. ![](https://storage.crisp.chat/users/helpdesk/website/-/7/7/c/6/77c66f5e87ea8c00/capture-decran-2025-07-10-a-16_9x6qn6.png =496xauto) * In the “**Content**” section, select the “**Dark Post**” option, then “**Import content**”. * Upload the video or image you wish to use. * Add a caption  ![](https://storage.crisp.chat/users/helpdesk/website/-/7/7/c/6/77c66f5e87ea8c00/capture-decran-2025-07-10-a-16_31l0ni.png =536xauto) * Launch the campaign: your dark post will be visible only for the targeted audience. --- # III. Optimize my content for a campaign Optimizing your videos or images is essential to maximize the impact of your advertising campaigns. Here are our best practices to ensure optimal performance:   ### __Respect technical specifications__ Each platform has its own requirements. Here are the key points: **Recommended file formats :** * **Video** : MP4 ou MOV (compression H.264, audio AAC). * **Image** : JPG ou PNG.   **Ideal resolutions:** * **Stories/Reels** : 1080 x 1920 px (ratio 9:16). * **Feed** : 1080 x 1080 px (ratio 1:1) ou 1080 x 1350 px (ratio 4:5).   **Maximum file size :** * **Video** : 4 Go. * **Image** : 30 Mo.   ||| WARNING: Carousels are not compatible with listener and save campaigns. They can be used for audience growth and sales campaigns. For engagement and awareness campaigns, carousels are allowed only without a link, or with a link to your Instagram profile. ### __Create eye-catching visuals__ * **Put forward a clear message**: The image or video should capture attention from the very first seconds. * **Avoid cluttered elements**: Leave space so that your message is easy to read. * **Color and contrast**: Use colors that stand out and catch the eye.   ### __Add text and subtitles__ * **Text in videos**: Limit to 20% of visual space to avoid an overloaded look. * **Subtitles**: Particularly useful for videos that will be viewed without sound.   ### __Avoid common pitfalls__ * **Poor resolution**: A blurred image or pixelated video will have a negative impact. * **Too much text**: Keep it concise and to the point. * **Elements hidden by the interface**: Check that the platform's buttons or icons don't hide important information. --- # IV.
