RDPSchool is not a separate company or service. The brand has been retired and rdpschool.com now points here permanently.
Same team, same servers, same support — new name. Existing RDPSchool accounts, services and renewals continue exactly as before; only the name and the web address have changed.
Decide how your links look when they are shared on Facebook, LinkedIn, WhatsApp, Slack, Telegram and X. Fill in a few fields, preview the card and copy ready-made meta tags, or audit the tags a live page already has.

GENERATED TAGS
After publishing, refresh old previews with the Facebook Sharing Debugger ("Scrape Again") and the LinkedIn Post Inspector. To roll back, remove these lines from your template.
LINK CARD PREVIEW
HOW TO USE IT
Start from scratch or from a live page; the generated tags update as you type.
Enter a URL under Start from a live page to audit its current tags and share image. The form is filled with what the page already declares.
Keep the title under about 60 characters and the description under about 160. The counters warn you when text is likely to be cut short.
Use the canonical page URL and an absolute image URL. The preview loads the image so you can see how it will be cropped.
Copy or download the tags and paste them into the page's <head>. In a CMS, use your SEO plugin's social fields instead of hard-coding them.
Open Graph is a set of <meta property="og:…"> tags that tell social networks and messaging apps what to show when someone shares a link: a headline, a short summary, an image, the site name and the canonical address.
Without them each platform guesses, often picking a logo, an advert or nothing at all as the image, and the first line of the page as the description.
X reads its own twitter: tags first and falls back to Open Graph for anything missing. The one tag it really needs is twitter:card, which chooses between a small square thumbnail and a wide image card.
The generator outputs both sets from the same fields, so every platform shows the same wording.
Use 1200 × 630 pixels, keep text and logos away from the edges because some apps crop to a square, and keep the file small so messaging apps do not skip it. The image must be publicly reachable: not behind a login, a hotlink rule or a firewall that blocks bots.
If you serve images from your own VPS, make sure your hotlink protection allows the crawlers of Facebook, LinkedIn and X.
Platforms cache link previews, sometimes for weeks. After changing your tags, ask Facebook to re-scrape in the Sharing Debugger and LinkedIn in the Post Inspector. Messaging apps refresh on their own over time; adding a harmless query string such as ?v=2 to the shared link forces a fresh fetch.
The tags are generated in your browser and nothing you type is sent to VPSLake. The preview image is loaded by your browser directly from the address you enter. Only the optional page audit uses the VPSLake server, and it does not store the URL or the page. The preview is an approximation; final appearance is decided by each platform.
FREQUENTLY ASKED QUESTIONS
og:title, og:type, og:image and og:url as the basic four. In practice add og:description and og:site_name as well, plus twitter:card for X. The generator outputs all of them whenever you fill the matching field.og:url to group likes and shares, so it should be the clean canonical address without tracking parameters. If it differs from your canonical tag, shares of the same page can be counted separately.<title> and meta description are for search engines, while og:title and og:description are for social cards. Many sites use a shorter, more conversational headline for sharing.
