SERP and Meta Tags Previewer
Check the title, meta description, Open Graph and Twitter Cards of up to 500 URLs, and preview how they appear on Google, Facebook and X. Measured in characters and in pixels, which is what Google actually truncates.
What this previewer checks
It downloads the HTML of each URL and extracts the tags that decide how your page looks in a search result and when shared. For each it measures length in characters and in pixels, and turns that into a grade from A to D.
- Title and meta description, with their character length and real pixel width.
- H1, canonical and meta robots, to catch pages carrying noindex or a canonical pointing somewhere else.
- Full Open Graph: og:title, og:description, og:image, og:url, og:type and og:site_name.
- Twitter Cards: card, title, description and image, plus the viewport for the mobile view.
How to preview your snippets step by step
Title Tag
Paste the URLs you want to review, one per line, or use “Paste list” if they live in a spreadsheet. You can enter up to 500 depending on your plan and they are all analysed at once, so reviewing a whole section costs the same as reviewing one page.
Meta Description
Run the analysis and use the simulator: switch between the desktop and mobile views to see where each text gets cut. Truncation is not the same in both, and most failing titles only fail on mobile.
How to read the grade and the preview
- ·Grade A — everything essential is there and within length. Nothing to change.
- ·Grade B — something recommended is missing, usually an Open Graph tag or a short description.
- ·Grade C — title or description missing, or one of them clearly truncates in the SERP.
- ·Grade D — the page lacks the basics, or carries a noindex that keeps it out of the index.
- ·The noindex warning is independent of the grade: if it shows, deal with it before anything else.
- ·The preview shows the text already decoded, exactly as a searcher sees it, not as it sits in the HTML.
Grade A · title 512 px · description 890 px · og:image present
Grade D · no meta description · noindex detected
What to check on each page type
- ·Home: that the title is not just the brand and that og:image is set, since it is the most shared page.
- ·Product or service pages: that each has its own description, not the repeated template.
- ·Listings and pagination: that page 2 onwards does not repeat page 1's title and description.
- ·Blog posts: that the SERP title and the H1 are not identical when the H1 has grown long.
- ·Campaign landings: that the canonical points at itself and not at the homepage through a template slip.
every URL with its own title and its own meta description
the same description repeated across 40 product pages
Always compare the mobile view: Google indexes with the mobile crawler and there is less room there, so a title that fits on desktop can appear truncated.
