Enhance your email signature by adding social media icons. Discover step-by-step instructions to turn every email into a powerful marketing tool.

Getting someone to share your online listing should be a win, but it quickly turns into a marketing headache when it shows up on Facebook as a broken link with the wrong photo and a confusing title. You’ve put a lot of work into your product, property, or service, and a poorly formatted share undermines all of it. This guide will walk you through everything you need to know - from simple onsite tweaks to the specific code Facebook looks for - to get your listings looking perfect and clickable every single time they’re shared.
Before you even think about how your link will look on Facebook, you need to make sure the destination itself is compelling. A perfectly shareable link that leads to a confusing or unappealing page won’t do you any good. Your goal is to create a listing that people not only want to click on but also feel good about sharing.
We're visual creatures. The very first thing anyone notices - both on your listing page and in a Facebook preview - is the primary image. If your main photo is blurry, poorly lit, or doesn’t accurately represent what you're offering, you've lost potential interest before anyone reads a single word.
Your headline is the first piece of text someone reads. It needs to be direct and informative. A vague or clever-but-confusing headline will get skipped over.
The first headline tells the user exactly what they're getting. The second one is fluff that forces the user to dig for information. Be specific and lead with the most important details.
No one wants to read a wall of text. Break up your description using short paragraphs, bullet points, and bold text to highlight key features. Think about what a potential customer needs to know to make a decision and put that information front and center.
Okay, now for the part that directly controls how your link looks on Facebook. When you paste a URL into Facebook, a crawler (called the "Facebook scraper") quickly visits your page to find specific information to create that nice-looking preview with an image, title, and description. It looks for special snippets of code in your website’s HTML called Open Graph (OG) tags.
If you don’t have these tags, Facebook just guesses what to show. The result? It often pulls a random image from your sidebar, a headline from a different section, or just shows a plain, unexciting link. By adding OG tags, you explicitly tell Facebook what to display.
These tags go inside the <,head>, section of your website’s HTML. Don't worry if that sounds intimidating, most modern website builders and plugins handle this for you behind the scenes.
Here’s what they look like in code:
<,meta property="og:title" content="Your Catchy Listing Title Here" />,
<,meta property="og:description" content="A brief, engaging summary of your listing (around 1-2 sentences)." />,
<,meta property="og:image" content="https://www.yourwebsite.com/path/to/your/amazing-image.jpg" />,
<,meta property="og:url" content="https://www.yourwebsite.com/your-listing-page-url" />,
og:title: This is the bolded headline that appears in the share preview. It should be concise and compelling, similar to your page's H1 title but can be customized for a social audience.og:description: The snippet of text below the title. It’s your chance to add a bit more context and encourage a click. Keep it to one or two enticing sentences.og:image: This is arguably the most important one. It's the full URL of the image you want to feature. For best results, use an image that's at least 1200 x 630 pixels.og:url: This is the "canonical" URL of your listing. It helps ensure that all shares point back to the same page, consolidating likes and comments.You don't need to be a developer to get this done. Most content management systems (CMS) and e-commerce platforms have made this incredibly easy.
If you have a WordPress site, this is a breeze. SEO plugins like Yoast SEO or Rank Math have built-in social sharing features. When you’re editing a page or post, look for the plugin's settings box (usually below the main content editor). You’ll find a "Social" or "Sharing" tab where you can manually set the Open Graph title, a custom description, and upload a specific image just for Facebook sharing.
This is extremely useful because it lets you optimize your page title for Google search while creating a more conversational title for Facebook.
Platforms like Shopify are built for selling, so they know how important social sharing is. Most of them automate OG tags for you. Your product title becomes the og:title, the product description becomes the og:description, and your main product image becomes the og:image.
If you navigate to a product page in your Shopify admin, you can often edit the SEO settings at the bottom to tweak the page title and meta description, which sometimes affects the OG tags. Some Shopify themes or apps also provide a specific field for a "social sharing image," which gives you more direct control.
This is the tool a lot of professional marketers use, and it's completely free. Even after you’ve set up your OG tags perfectly, Facebook sometimes holds onto an old, cached version of your link preview. The Sharing Debugger forces Facebook to re-scan your page and update its preview data.
Here’s how to use it:
Always use the Sharing Debugger before you publicly post a brand-new or recently updated listing link to Facebook. It lets you check your work and make sure your preview is perfect.
Getting your link to display correctly is half the battle. Now, you need to create a context that encourages people to click and share.
Never just drop a link into a Facebook post and hope for the best. You need to frame it. Add a caption that engages your audience and provides context.
Facebook Groups can be an amazing place to share your listing with a highly relevant audience. But you must follow the rules. Many groups have strict policies against self-promotion. Others might have dedicated threads for listings or allow links only on certain days.
Always read the group rules before posting. Participating genuinely in the community - not just dropping links - will build trust and make people more receptive to what you’re offering.
Don't be afraid to ask for a share! You can do this subtly on the listing page itself with social sharing buttons. Or you can be more direct in your Facebook post's caption:
"Know someone who’d love this place? Feel free to share this post with them!"
This simple call-to-action can remind people that sharing is a great way to help both you and their friends.
Making a listing look good on Facebook comes down to two things: setting up your page for success with great visuals and clear copy, then using Open Graph tags to tell Facebook exactly what to show. Once you add the free Facebook Debugger tool to your workflow, you’ll have complete control over how your hard work is presented online.
