Does OG replace normal meta description?

No. Open Graph is for social/link preview contexts. Standard meta description is still important for search snippets.

Should every page have a unique OG image?

Not strictly, but tool pages perform better when image content reflects the exact task. Generic images reduce preview relevance.

Why are preview changes not immediate?

Platforms cache previews. After changing OG tags, re-scrape/debug the URL and confirm final deployed HTML includes the updated fields.

Open Graph Tags for Better Link Previews

When someone shares a URL in chat apps or social networks, Open Graph data often controls the preview card. If your OG tags are missing or inconsistent, your post can appear with wrong text, weak images, or unrelated metadata.

For AllSVGIcons, this matters because tutorials and tools are frequently shared in developer communities.

What Open Graph controls

At minimum, Open Graph should provide:

og:title
og:description
og:url
og:image
og:type

These fields define the identity and presentation of the shared URL.¹

Recommended defaults for this project

For tool pages

og:type: website
Title: action-driven and task-specific
Image: screenshot showing the tool UI

For blog posts

og:type: article
Title: exact article title
Description: one clear summary sentence
Image: topic-specific visual, not a site-wide generic placeholder

This split helps shared previews communicate intent instantly.

Image guidance that avoids broken previews

Use an absolute image URL and keep files lightweight but clear. A common target for social previews is 1200x630.

Practical checklist:

Image URL returns 200 and is crawlable.
No auth needed to fetch image.
Not blocked by robots or headers.
Content matches page topic.

Debug workflow

When previews look stale or wrong:

Confirm OG tags in final rendered HTML.
Verify canonical URL alignment.
Re-scrape URL using platform debugger tools.
Check if the image URL changed but cache did not refresh.

Tool-page pattern

Use one OG image style template per tool family, but do not reuse the exact same image across all tools.

Example block

<meta property="og:type" content="website">
<meta property="og:title" content="Free SVG Optimizer - Clean and Compress SVG Code">
<meta property="og:description" content="Optimize SVGs in your browser with SVGO-powered options and copy-ready output.">
<meta property="og:url" content="https://allsvgicons.com/svg-optimizer/">
<meta property="og:image" content="https://allsvgicons.com/og/svg-optimizer.png">

Common Open Graph mistakes

Relative image URLs instead of absolute URLs
Copy-paste metadata that still references old pages
Generic descriptions with no user task context
Mismatch between og:url and canonical URL

Each mistake reduces preview quality and weakens trust when links are shared.

Practical FAQ
