This page explains every card, then lists the limits the composer checks before it lets you schedule. **You need:** a post open in the composer with at least one channel selected. ## Options that work on several networks | Option | Where | Networks | | --- | --- | --- | | **Add first comment** | **Posting options** | Facebook, Instagram, Threads, LinkedIn, X, Bluesky, YouTube | | **Mark media as made with AI on supported networks** | **Posting options** | TikTok (video posts), X (posts with media) | | Alt text | The lines icon on an image | Facebook, X, LinkedIn, Pinterest | | Tag people | The person icon on an image or video | Instagram | | **Video Thumbnail setting (Instagram, TikTok, Pinterest only)** | Under the media | Instagram, TikTok, Pinterest | ### Add a first comment Turn on **Add first comment** and type the comment. Robopost posts it on your post as soon as the post is live. On X the first comment is a reply, and it uses its own [X credits](https://dash.robopost.app/docs/posts/x-credits.md). ### Add alt text to an image 1. Add the image to the post. 2. Click the lines icon on the image. 3. In **Alternative Text for Image**, describe what the image shows, then click **Confirm**. Alt text helps people who use screen readers. Robopost sends it to Facebook, X, LinkedIn and Pinterest, and not to other networks. ### Choose a video thumbnail When the post has one video and you selected Instagram, TikTok or Pinterest, pick a frame under **Video Thumbnail setting (Instagram, TikTok, Pinterest only)**. That frame becomes the cover. YouTube has its own thumbnail upload, described below. ## Facebook In **Facebook Post Type**, choose: - **Post**: text with up to 10 photos, or one video, or one GIF. Facebook doesn't accept photos and a video (or a GIF) in the same post. - **Reel**: needs one video between 3 and 90 seconds. Use vertical video (9:16, 1080 × 1920 px). ## Instagram In **Instagram Post Type**, choose **Post**, **Reel** or **Story**. Every Instagram post needs at least one image, GIF or video. - **Post**: up to 20 photos and videos. Several items make a carousel. - **Reel**: one video between 3 and 90 seconds. - **Story**: one photo or one video (3 to 60 seconds), not both. ### Add a location to an Instagram post Instagram tags a location by its Facebook place ID. 1. Find the place on Facebook (for example through facebook.com/places) and open its page. 2. Copy the long number in the page's address. That is the location ID. 3. Paste it in **Location ID From Facebook** in the Instagram card. ### Tag people Click the person icon on a photo, click where the person appears, and pick a saved contact. On a video, pick the contacts to tag. Robopost uses each contact's Instagram handle. Story posts can't carry tags. See [Contacts](https://dash.robopost.app/docs/posts/contacts.md#tag-people-in-an-instagram-photo-or-video). ## TikTok The **TikTok settings** card appears once the post has a photo or a video. For a video post: - The post text is the caption. It is required. - **Duet**, **Comments** and **Stitch** are on by default. Turn one off to stop people using it on this video. For a photo post (up to 35 photos): - **Title** is required. - **Automatically add music** (on by default) lets TikTok pick a song for the photos. ### Can I add my own music to a TikTok post? Not from Robopost. TikTok doesn't let scheduling tools choose a sound. For photo posts, leave **Automatically add music** on and TikTok adds a song. For videos, include the audio in the video file before you upload it. ### Why doesn't my TikTok post have sound? - **You're watching on a computer.** TikTok's website often starts videos muted. Unmute the player. - **TikTok removed the sound.** TikTok mutes videos whose audio breaks its copyright rules or Community Guidelines. In the TikTok app, open the video and tap **View details** to see the reason. From there you can replace the sound with one from TikTok's library. Sounds from TikTok's own library don't get removed for copyright. ## YouTube YouTube needs a video. The post text becomes the video description. In **YouTube Settings**: - **Video Title**: required, under 100 characters. - **Video Privacy**: **Public**, **Private** or **Unlisted**. - **Choose Thumbnail**: upload a custom thumbnail image (optional). - **Video Type**: **Video** for a regular video, **Short** for a YouTube Short. For a Short, Robopost adds `#Shorts` to the description. - **Audience**: **No, it's not made for kids** or **Yes, it's made for kids**. YouTube doesn't accept the `<` and `>` characters in the title or description. ## Pinterest Each Pinterest channel is one board, so pick the channel of the board you want to pin to. In **Pinterest Settings**: - **Pin Title**: required, under 100 characters. - **Destination Link (optional)**: the page people reach when they click the Pin. A Pin takes one image, one GIF or one video. The post text is the Pin description (up to 500 characters). ## Google Business Profile In **Google My Business Post Type**, choose a tab: - **Standard**: an update. The text is required. Add a **Call to action button** if you want one. - **Offer**: fill in **Offer title**, **Offer start** and **Offer end** (at least one day in the future). **Coupon code**, **Redeem URL** and **Terms and conditions** are optional. - **Event**: fill in **Event title**, **Event start** and **Event end** (at least one day in the future). You can add a call to action button. The **Call to action button** can be **None**, **Book**, **Order**, **Shop**, **Learn more**, **Sign up** or **Call**. Every button except **None** and **Call** needs a **Call to action URL**. Photos must be at least 250 × 250 pixels, and Google Business Profile posts don't accept videos. ## WordPress When you select a WordPress site, the composer switches to a WordPress editor: - **Post Type**: **Post** or **Page**. - **Title**: required. - **Slug (optional)**: the end of the page's address. - The text editor, with headings, links, lists and formatting. - **Featured Image**: pick the post's main image. - **Categories** (posts) or **Parent page** (pages). A WordPress post goes to one site at a time and can't be combined with other channels. ## X (Twitter) X has no settings card. Instead the composer shows how many [X credits](https://dash.robopost.app/docs/posts/x-credits.md) the post will use. A post without a link costs 1 credit and a post with a link costs 14. ## Limits the composer checks Before it schedules a post, the composer checks it against each selected network and stops with a message if something doesn't fit. Fix the post, or unselect that network. | Network | Text | Media | | --- | --- | --- | | Facebook | 5,000 characters | Up to 10 photos, or 1 video, or 1 GIF | | Instagram | 2,200 characters | 1 to 20 items, photos at least 200 × 200 px, feed video 3 s to 60 min | | X | 280 characters (25,000 with X Premium) | Up to 4 images, video 0.5 to 140 s (10 min with Premium) | | Threads | 500 characters | Up to 20 items, video under 5 min | | Bluesky | 300 characters | Up to 4 images, video 0.5 s to 3 min | | LinkedIn | 3,000 characters | Up to 9 images | | Pinterest | 500 characters | 1 image, GIF or video.
