Cross-posting

How to cross-post from Google Business to Facebook

Google Business Profile posts are built for search intent — a searcher scanning your listing wants a tight announcement: what, when, how much, and a button to act on it. Facebook’s feed is a completely different contract. The people scrolling there didn’t search for you; they need a reason to stop. That means a 1,500-character GBP mini-post almost always needs to grow, not shrink, when it moves to Facebook — adding context, a conversational hook, and a social reason to comment or share that a GBP post was never designed to carry.

The image tells the same story in reverse: GBP thumbnails favour a roughly 4:3 frame, while Facebook’s feed leans portrait (4:5 or square) and populates a link-preview card when you include a URL. This guide maps the genuine expansion work — and the handful of things that flip entirely — when you repurpose a Google Business update as a Facebook post.

Google Business vs Facebook: the spec deltas

Everything that changes between the two composers, side by side.

Google BusinessFacebook spec mapping. Limits last verified June 2026; platforms change these quietly, so check the composer when in doubt.
SpecGoogle Business (from)Facebook (to)
Primary canvas1200 × 900 px · 4:3 (post image)1080 × 1350 px · 4:5 (post)
Caption limitPosts up to 1,500 characters63,206 characters (feed truncates after a few lines with “See more”)
Video lengthPhotos preferred; videos up to 30 seconds / 75 MB per Google’s help docsLong feed uploads supported (hours); Facebook Reels are far shorter — check the composer for your account’s cap
HashtagsNo hashtag culture — Google Business posts read like mini announcementsSupported but lightly used — one or two at most reads native on Facebook
Image aspect ratioRoughly 4:3 — 1200 × 900 px commonly recommended for GBP posts4:5 portrait (1080 × 1350 px) or 1:1 square native to the Facebook feed
CTA / link formatStructured button (Learn more, Book, Call now) tied to verified profileInline URL or link-share post generating a preview card; no structured button
Post lifespanStandard updates fade from prominence after about a week; Offers/Events last to their end dateStays on your Page; feed reach decays over days but the post remains permanently

The good news

What transfers cleanly

  • The core announcement: the offer text, event dates, price, and product details inside a GBP post are exactly the kind of concrete information a Facebook audience values — the facts move cleanly, even if the frame needs rewrapping.
  • The photo as a file: Google Business accepts JPG or PNG up to 5 MB, and that same file works on Facebook — only the crop changes from the 4:3 GBP canvas to Facebook’s preferred 4:5 portrait or 1:1 square.
  • The link: a URL that powered a Call now or Learn more CTA button on GBP can go directly into the Facebook post body or as a link share with a preview card.
  • The weekly cadence: if you already post weekly to GBP to keep the listing fresh, that discipline translates directly — Facebook rewards consistent posting too.
  • Offer and event details with dates: a limited-time offer or event that used the GBP Offer or Event post type carries its structure to a Facebook Event or a time-stamped sale post.

The fine print

What breaks in transit

  • The announcement-only tone: GBP posts are functional mini-notices read by searchers in high-intent mode; Facebook posts that open with "Now open on Sundays" and stop there feel cold in a social feed — add a conversational hook, a question, or a reason to engage.
  • The image crop: a 4:3 GBP-optimised photo (1200 × 900 px) loses side context in Facebook’s 4:5 portrait frame and renders with letterboxing in the feed — re-crop to 1080 × 1350 px or 1080 × 1080 px with the subject centred.
  • The character budget goes in reverse: GBP hard-stops at 1,500 characters, so posts written to that ceiling can paste into Facebook’s 63,206-character field without truncation — but Facebook surfaces a "See more" link at roughly 477 characters on desktop, so the opening lines still need to carry the essential message.
  • Hashtags need to be added: Google Business posts have no hashtag culture at all; Facebook supports them and one or two well-chosen tags is the platform norm — a GBP post arrives with none, which is fine, but a deliberate tag can widen organic reach.
  • The CTA button becomes a link: Google’s structured CTA buttons (Learn more, Book, Call now) don’t exist in Facebook posts — replace them with a direct URL or a link-share post that generates a preview card, and write out the action you want readers to take.

Step by step: by hand vs with SocialKit

The manual way

  1. Copy the GBP post text and rewrite the opening sentence as a social hook — lead with a reason someone mid-scroll should care, not just the bare announcement.
  2. Expand where useful: you have 63,206 characters to work with, and a short backstory, a behind-the-scenes detail, or a direct question can turn a functional update into a piece of content worth engaging with.
  3. Replace the GBP CTA button with an explicit call to action in the text, then add the URL — either inline for a link preview card or as the first comment.
  4. Re-crop the image to 1080 × 1350 px (4:5 portrait) or 1080 × 1080 px (square) with the subject centred, so it fills the Facebook feed frame cleanly.
  5. Add one or two relevant hashtags at the end of the post — keep it to a handful at most, as a long tag block reads out of place in the Facebook feed.
  6. Schedule for a Facebook-appropriate time — GBP posts go live for searchers around the clock, but Facebook reach peaks at specific windows for your audience.

With SocialKit — compose once, customize per network

  1. Compose once: write the update in SocialKit’s composer and select both Google Business and Facebook.
  2. Customize per network on the same screen: keep the concise GBP version and expand the Facebook variant with a social hook, conversational copy, and a hashtag or two — without re-uploading the image.
  3. Schedule each platform into its own slot: the GBP post can go live immediately to serve searchers, while the Facebook post goes out at the best engagement window for your audience.
  4. Let SocialKit publish automatically, then compare per-post results in its analytics to see how the same content performs for searchers versus followers.

Pro tips

Tip 1

Treat the GBP post as a brief: it already contains the hard facts — use those as a skeleton and write the Facebook post around them rather than starting from scratch.

Tip 2

Phone numbers are fine in Facebook post text (Google’s content policy has restricted them in GBP post text) — if the GBP version routed readers to a Call now button, you can write the number directly into the Facebook caption.

Tip 3

GBP Offer posts expire on their end date; Facebook posts stay on your Page indefinitely — if the deal has closed, either archive the Facebook post or edit it to reflect the outcome.

Do I need to rewrite a Google Business post to use it on Facebook?

The facts don’t need rewriting, but the frame usually does. GBP posts are written for searchers in high-intent mode; Facebook posts land in a social feed where a conversational hook, a question, or a share-worthy angle helps the same content travel further. A direct paste typically works for the core details — add an opening line and a closing prompt to engage.

What image size should I use when posting to Facebook from Google Business?

GBP posts favour a roughly 4:3 canvas (1200 × 900 px is the commonly recommended size). Facebook’s feed renders images best at 4:5 portrait (1080 × 1350 px) or square (1080 × 1080 px). Re-crop the same photo with the subject centred so Facebook’s feed frame doesn’t letterbox or clip it.

Can I include a phone number in the Facebook post if Google Business removed it?

Yes. Google’s posts content policy has restricted phone numbers in GBP post text — that’s a Google-specific rule. Facebook has no such restriction, so if the GBP version routed readers to a Call now button instead, you can write the number directly into the Facebook caption.

How do hashtags work differently between the two platforms?

Google Business posts have no hashtag culture — there is no tag-based discovery on a Business Profile listing. Facebook supports hashtags and one or two relevant tags is the platform norm; a handful used thoughtfully can extend organic reach. Add them when you adapt the post, but keep the count low — a wall of tags reads as out of place on Facebook.
