Embedding content from multiple online sources to your presentation is really easy. For example you can embed:

  • Fully interactive live-websites, like your company's website
  • Videos from YouTube or Vimeo for example
  • 3D images
  • 360° panorama images
  • Charts and graphs from Google Slides, Google Data Studio or Microsoft Office 365 for example

What and why of embedding websites

  • Websites are a good way to add contact or order forms to a Seidat presentation.
  • The websites can be used as in a browser.
  • If the website has blocked Iframe embedding, it cannot be embedded to Seidat. Please contact the site administrator to allow Iframe embedding. More info at "Troubleshooting" at later in this article.
  • Embedding HTTP-websites requires few additional steps. More info at the end of this article.

Adding content to the slide with iframe

  • Start by clicking the website icon on the left toolbar. The icon is highlighted blue in the picture below
  • A frame opens and a toolbar opens on the top of the screen.
  • Copy the URL address you want to embed to the slide. You can add videos, websites, 3D images, etc. to the frame as long as they are hosted on the web in a service that allows embedding to other sources.
  • Paste it into the address bar field on top toolbar in Seidat. Press save icon next to the address bar.
  • You can resize the frame to fit the rest of the page's content.
  • Note that when sharing the presentation by using Seidat Live, the recipient of the presentation does not see actions done on the website by the presenter.


Some websites do not allow themselves to be embedded in iframes. This behavior is dictated by the following HTTP headers set on the website server:

  • Content-Security-Policy: frame-ancestors (supported in modern browsers, not supported in Internet Explorer).
  • X-Frame-Options (supported in Internet Explorer, not supported in modern browsers).

To allow the website to be embedded only in Seidat, set those headers to:

Content-Security-Policy: frame-ancestors *.seidat.com;
X-Frame-Options: ALLOW-FROM https://app.seidat.com/

Alternatively, you can remove those headers altogether, which will allow embedding the website on any page.

Adding HTTP (non secured) websites


By default for security reasons, HTTP (unsecured) Iframes cannot be embedded within Seidat using HTTPS protocol, since any communication between the HTTP iframe and the server it is hosted on is not secure. This is to prevent phishing scams and other attacks. When viewing a presentation in HTTP mode someone on the same network may intercept your traffic and view the presentation. As such, HTTP viewing is not recommended if your presentation content is sensitive. Never share the HTTP URL of the presentation since it can be accessed by anyone who has a link to it. For security reasons you will not be logged in while using the app in HTTP mode.

If you still wish to embed a website running on HTTP protocol follow the steps below

  • Go to the Presentation settings from the left toolbar (gear icon).
  • Under Security, toggle "Allow unsecured (HTTP) presentation viewing"
  • Seidat will turn the HTTP mode on if there is HTTP content embedded. If there is no HTTP content, Seidat will remain in HTTPS.
  • When entering presentation mode, Seidat will confirm the transformation to HTTP mode.
  • If you are the moderator of the website, it is recommended to add the HTTPS protocol to the website to make it easier to embed it to a presentation. Google also prefers websites in their search results that have the protocol installed.
