Publish a listing to social media page

What it is

Publisher posts your listing to several channels at once: social networks and classified boards. You prepare the post once, pick the channels, and publish now or on a schedule.

Publisher is available in the cabinet (web), under Tools.

Channels

You connect a channel once, under Tools > Publisher: a social network by signing in to your account, Telegram through a bot. After that the channel is available for every post.

Instagram and TikTok cannot be connected at the moment: the GREM apps are under review on the platforms' side. Accounts connected earlier keep working as before.

Media requirements

  • Photos - JPG, PNG or WEBP, up to 15 MB.
  • Video - MP4, MOV or WEBM, up to 300 MB.
  • Clip length is capped by the platform itself: TikTok up to 10 minutes, Instagram up to 90 seconds, X up to 2 minutes 20 seconds, Facebook up to 45 minutes. Telegram limits the file size instead - 50 MB.
  • Facebook and YouTube accept a schedule on their own side; every other channel is posted by the GREM scheduler.

The Reminder channel

When a platform does not accept the selected format directly, the post goes through the Reminder channel: at the scheduled time you receive the finished material and post it yourself. This is not automatic publishing, and such a post carries its own status in the history.

How to publish a listing

Open Publisher

Go to the cabinet, Tools > Publisher.

Connect channels

Connect the social networks you need (log in with your account) or Telegram. You connect once - after that the channel is available for all posts.

Pick a listing and compose the post

Choose a listing, add text, photos, or video. You can use a ready-made template (see below).

Publish now or schedule

Publish right away, or set a date and time so the post goes out automatically on schedule.

Listing lifecycle templates

To avoid writing text every time, use ready-made templates per event:

  • Just listed
  • Open house
  • Price drop
  • Under contract
  • Just sold

Listing data is filled in automatically: name, address, price, currency, description. You can also create your own templates.

Video from photos

Publisher can build a short video from a listing's photos (9:16 or 1:1 formats) - handy for TikTok, Reels, and Stories.

Post review

You can send a post for approval to a colleague or the listing owner via a link - they open it without an account, leave a comment, and approve or reject the post.

  • Analytics - a 24-hour overview: how many posts went out, how many are in progress, how many failed.
  • Short links with click counts.
  • Link-in-bio page with your listings and a lead capture form.

Post format

The publishing form has a Format field: Post, Story, Reels / Shorts, Carousel, Thread or Poll. The format decides how the network takes the material: a story needs a single frame, a poll needs a question and answer options, and the 9:16 preview shows how a story or a Reel will look before it is sent. If the chosen format is not accepted by the network directly, the publication goes through the Reminder channel: you get the finished material and post it yourself.

Hashtags and the AI assistant

Below the post text there is a hashtag bar: Sets: keeps your saved sets, From the listing: suggests hashtags by the city and property type. A set is saved under its own name and applied in one click.

The AI assistant: bar writes text from scratch, improves and shortens yours, rewrites it for a specific network within its length limits, adds a call to action, picks hashtags and translates. The result is inserted into the form with a button.

Crop for the network

The Crop for the network button opens a photo editor: ready-made proportions for each network, rotation, cropping. Stories have their own builder: a photo, a layout, a headline, the price, the address and a call to action come together in a single 1080x1920 frame.

Telegram post settings

A post for a Telegram channel has its own options: Silent (no sound), Media under spoiler, Pin after posting, link preview off, a topic and buttons below the post. The Poll format is published to Telegram as a real poll. A published post can be edited or deleted from the platform right from the publication card within 48 hours.

Engagement

The publication card shows a line of channel metrics: views, reactions, comments and shares. Refresh metrics pulls fresh numbers, and the analytics section sums up Engagement across all channels.

From the card of a finished post you can Duplicate as new post with the same settings, and finished records can be removed with Remove from history.

Billing

Every post is charged from your GREM wallet balance. Make sure your balance has enough funds. More details: pricing plans.

Tips

  • Prepare the listing description in advance - you can generate the text quickly in the Content Generator.
  • For long-term promotion, plan posts ahead using the schedule.
  • Check the channel's daily limit: if it is used up, a "now" post will have to be rescheduled.

Common questions

Which channels are supported?

Facebook, Telegram, LinkedIn, YouTube, X, Instagram, TikTok, and a separate Reminder channel. Daily post limits and caption lengths differ and are collected in the table in this article.

Why can I not connect Instagram or TikTok?

The GREM apps are currently under review on those platforms. Accounts already connected keep working as before.

What is the Reminder channel?

A fallback for when a platform will not take the format directly: at the scheduled time you get the finished material and post it yourself. It is not automatic publishing.

Which files can I attach?

Photos as JPG, PNG or WEBP up to 15 MB; video as MP4, MOV or WEBM up to 300 MB. Clip length is capped by the network itself.

Can I show the post to the owner before it goes out?

Yes. A post can be sent for approval by link: the person opens it without an account, comments, and approves or rejects it.
