Meta tag checker and link preview

Facebook's sharing docs (checked 14 November 2026) recommend 1200 x 630 px. Images under 600 x 315 px show as a small thumbnail, and images under 200 x 200 px are not shown. Keep the shape close to 1.91:1. For X large image cards, keep the file under 5 MB and use JPG, PNG, WEBP or GIF, not SVG.

LinkedIn, Facebook and X store a copy of a link preview the first time the link is shared. After you fix your tags, ask each platform to read the page again with its own tool: the Facebook Sharing Debugger or the LinkedIn Post Inspector. New shares then use the new tags.

You need one: twitter:card. It tells X which layout to use, for example summary_large_image for a big picture. For the title, description and image, X falls back to your og:title, og:description and og:image, so you do not need to repeat them.

Google publishes no fixed limit. It cuts text to fit the width of the screen. The Google preview in this tool cuts titles at 60 characters and descriptions at 160 characters, the same lengths Leadee's technical SEO audit uses. Treat these as a guide, not a hard rule.

No. Google's Search Central docs say it may write its own title link and snippet when it thinks other text on the page fits a search better. A clear, unique title and description that match the page make that less likely. A noindex or nosnippet robots tag stops the snippet completely.

Both read Open Graph tags: og:title, og:description, og:image and og:url. If og:title is missing, the preview usually falls back to the page title. Neither publishes its own image size rules, so this tool applies Facebook's Open Graph numbers to their previews.

At most three requests: your robots.txt, the page itself, and the first 1 MB of the og:image. If your robots.txt asks crawlers like ours not to read the page, we stop and tell you. No AI model is used. Results are cached for 24 hours.

No. AI answer engines change their output frequently, and no vendor — including Leadee — can guarantee a ranking or a mention. Leadee publishes confidence intervals on every metric so you can see how much a result can vary run to run.

Leadee runs your prompt set against each AI engine on a weekly to daily schedule, depending on plan, through official vendor APIs (OpenAI, Gemini, Perplexity, Anthropic, DataForSEO) — never by scraping consumer chat interfaces — and reports mention rate, citation rate, average position, share of voice and sentiment with a 95% confidence interval.
