Open Graph Previewer

What's Open Graph?

Open Graph (OG) is a web-based metadata protocol that controls the display of links in social media: titles, descriptions, pictures, types and station names. Write in HTML <head> It's... og:* In the label. Without OG, the platform may randomly intercept the text, leading to poor visibility and low clicks on the shared card.

Core label list

• og:title: sharing titles, suggesting value emphasis and avoiding excessive interruptions
• og:description: Supplementary description, approximately 70-200 characters depending on the platform
• og:image: Preview of large maps, first HTTPS absolute address
• og:url: regularize links, reduce repetition of argument pages
• og:type: e.g. website, article
• og:site_name: branding/post count
• twitter:card:summary or summary large image

Multiple platform differences

Facebook / LinkedIn More dependent on OG photo scales;X（Twitter） The Twitter card is available;Slack Displays site colours and summaries often. The same labels are difficult to perfect on all platforms, but uniform high-quality maps + clear titles are usually sufficient.

Optimization of the list

1. The 40-60 character contains core information before the title
2. The description says, "Who's good for what? + what you get."
3. Picture 1200 x 630, text is small, subject is centered, avoiding edges
4. og:url corresponds to canonical
5. Recheck caches using platform debugging tool after re-engineering

Checking of common problems

• Image does not show: relative path, chain of protection, oversized, non-HTTPS
• Old title: Platform cache not refreshed
• Multiple Conflict Tabs: CMS Plugin Repeat Output
• SPA Site: First Screen HTML Undeclared Meta, Carcinators Only See Shell

How this tool works

Enter the URL to look at the multiplatform preview and tab and to change the site template as suggested. Some sites may not be accessible in real time due to browser inter-domain limitations, and examples of structures will be presented to facilitate your cross-references to your own labels.

Relationship to SEO

OG primarily influences social distribution and clicks, which do not directly equate to Google ranking factors; But higher share clicks can lead to traffic and brand searches. It is recommended to be maintained with the title/description, structured data.

FAQ

Why are there examples of data sometimes? When you cannot directly capture any site under a cross-domain limit, you will use an example to demonstrate the preview structure.

OG and Twitter, like Card? Not exactly the same; Twitter can be reused by OG or can be used to separate twitter: tabs.

Picture size advice? Regular 1200 x 630 to ensure the preview of the large map and the cut-off of the security zone.

Is the label effective now? Platforms often have caches and can be used to compute tools to force refreshing.
