What is an Open Graph image?

When you paste a website link into Facebook, LinkedIn, WhatsApp or a text message, you often see a neat little card with a picture, a title and a short line of text. That picture is the Open Graph image. It comes from a small piece of code on your page called an Open Graph tag, which tells other platforms exactly what to show. Without one, your link can appear as bare text or a random cropped photo, which looks unfinished and gets fewer clicks.

It matters because that preview is often the first impression people have of your business before they even visit. A clear, on-brand image with your logo or a strong photo makes the link feel trustworthy and worth tapping. Think of a local bakery sharing its new menu page: with a good Open Graph image, the post shows a warm photo of fresh bread and the shop name, so friends and followers instantly know what it is. It works hand in hand with your meta description and often shares space with your favicon across the web.

You do not have to touch any code or design a special sharing image. Promino automatically generates a clean, branded Open Graph image for every page using your site name, page title and colours, so every link you share looks polished from day one.

It also fills in the matching Open Graph tags and other metadata behind the scenes, keeping everything consistent as your site grows. You can see how this fits into the wider picture on our SEO page.
