Stop checking by hand

Want your whole site audited — and this checked on every deploy?

Checking one page is easy. Catching a missing og:image, a truncated title, or a broken share card across hundreds of pages — every time you ship — is a job for automation. Victech builds the scraper that audits your entire site and the check that runs on every deploy, so a bad share card never reaches production.

Open Graph & social preview questions, answered

What are Open Graph tags?
Open Graph (og:*) tags are <meta> tags that tell Facebook, WhatsApp, LinkedIn, Slack and most other platforms how to render your link when it’s shared — the headline (og:title), summary (og:description), and preview image (og:image). Without them, platforms guess from the page, often picking the wrong text or no image at all.
Why is my link sharing without an image?
Almost always because the page has no og:image tag, the image URL is relative or broken, or the image is too small. This checker shows you exactly which tag is missing and whether the image URL resolves. A large, valid og:image is the single biggest driver of share click-through.
What is a Twitter card and do I still need twitter:* tags?
A Twitter (X) card is the rich preview shown when a link is posted on X. X reads twitter:* tags first and falls back to Open Graph, so you can often get a good card from og:* alone. Declaring twitter:card as summary_large_image gives you the most reliable large-image preview.
What’s the ideal og:image size?
A 1200×630 pixel image (1.91:1 ratio) is the safe default — it renders as a large card on Facebook, LinkedIn and X without cropping. Keep important content away from the edges, and make sure the URL is absolute (starts with https://).
Does this tool change anything on my site?
No. It only reads your page’s public HTML and reports what it finds. It makes no changes. To actually fix the issues — or have them checked automatically on every deploy — that’s where Victech’s automation comes in.
Is this social share preview checker free?
Yes. It’s completely free, needs no sign-up, and shows the full result on screen. Sharing your email afterwards is optional — it just lets us run a full-site audit and follow up if you’d like the checks automated.

This tool reads the public HTML of the URL you provide and reports the social meta tags it finds. Some platforms cache previews — after fixing tags you may need to re-scrape (e.g. via the platform’s own debugger) to clear the old card.
