Content embedded from external websites like YouTube or Twitter load automatically if a visitor opens your page. Embed Privacy prevents loading of those content until your visitor explicitly consents.
But Embed Privacy not only improves the data protection to third parties, it makes your website even faster because less content is loaded directly.
The placeholders, which replace the embedded content, can be styled with a small amount of CSS to your liking.
With a click on the placeholder, the particular embedded content will be loaded and your visitors can view it.
