In today’s digital landscape, local search is more important than ever. If you’re just getting started with local SEO, Google My Business (GMB) is the perfect place to begin.

Your GMB profile gives potential customers easy access to key details about your business, like your address, contact info, and operating hours, right from Google Search or Maps.

By posting updates on your GMB page, you can promote your brand, special offers, events, and more. But to make your posts stand out and look polished, it’s crucial to use the correct image sizes.

In this article, we’ll cover the ideal GMB post image size guidelines and share tips to optimize your visuals for better visibility and engagement.

What are GMB posts?

GMB posts (short for Google My Business posts) are updates that businesses can publish directly on their Google My Business (now Google Business Profile) listings. These posts appear in the “updates” or “overview” tabs on Google Search and Maps, allowing businesses to share news, promotions, or other key information with customers.

Each post can include text (up to 1,500 characters, though 150–300 is ideal), images, and call-to-action buttons like “Learn More” or “Sign Up,” making them a versatile tool for engaging audiences and boosting visibility.

When users search for your business name or find you through Google Maps, your profile, along with your latest posts, shows up in the results. It’s a free and powerful way to communicate with customers in real-time.

There are several types, each with a specific purpose:

• Update Posts: Enable businesses to share important updates, such as new locations or product launches, with their customers.

• Offer Posts: Ideal for spreading the word about special promotions, including details such as promo codes and expiration dates in text and images.

• Event Posts: Used to advertise upcoming events (e.g., webinars, workshops, open houses) with essential details like date, time, location, and cost.

• Product Posts: Highlight specific products or services, drawing attention to unique features and details to attract interest.

Why GMB Posts Matter for Local SEO

GMB (Google Business Profile) posts play a crucial role in boosting your local SEO by increasing your visibility where it matters most on Google Search and Maps. Regularly posting updates, offers, and announcements signals to Google that your business is active, relevant, and trustworthy. This can help improve your chances of ranking higher in local search results. GMB posts also allow you to engage directly with potential customers by showcasing timely promotions, sharing useful information, and driving action through built-in CTAs like “Call Now” or “Visit Website.” In short, consistent GMB posting helps you stay top-of-mind, attract more local traffic, and convert searches into real-world visits.

Tips for Selecting the Best Images for Your Google Business Profile Posts

Visual content plays a powerful role in attracting attention—studies show it can increase a viewer’s interest in the content by as much as 80%. That’s why selecting the right images for your Google Business Profile (formerly GMB) posts is so important.

Here are a few tips to guide you when choosing visuals:

1. Use High-Quality Images

Images reflect your brand’s professionalism. Low-resolution or blurry visuals can leave a negative impression, making your business seem less credible. Stick with high-resolution images that are sharp, eye-catching, and visually align with your brand’s identity.

You can find great visuals on free image platforms like Unsplash and Pexels, which offer royalty-free content.

2. Choose Relevant Visuals

Content accompanied by meaningful visuals gets far more engagement. In fact, posts with relevant images are viewed nearly twice as often. Make sure your photos support the message you’re trying to communicate.

For example, a restaurant promoting a Friday-night deal should include photos of the actual dishes, paired with compelling text like “20% off tonight only!”

3. Avoid Oversized or Wide Images

Stick to the recommended GMB image size of 720 x 540 pixels. Wide-format images may be awkwardly cropped or resized by Google. For the best results, use photos with the subject clearly centered in the frame to maintain visual impact in both preview and full view.

GMB Image Size Guidelines for 2025

To ensure your images appear clear and well-formatted on your Google Business Profile, it’s important to follow the platform’s image size guidelines. Using the correct dimensions helps maintain visual quality and prevents cropping or distortion on different devices.

GMB Image Size Recommendations:

• Optimal Size: 1200 x 900 pixels

• Default Size: 720 x 540 pixels

• Maximum Size Allowed: 2120 x 1192 pixels
