1. There is no difference which website you embed.

2. No - The page that you include can set headers to avoid that a page can be integrated. Check your page here: https://www.advanced-iframe.com/advanced-iframe/free-iframe-checker

3. Please see https://www.advanced-iframe.com/advanced-iframe-resize-to-content-summary - If you can include one line of Javascript you can get auto height.

I’m currently using the Advanced iFrame plugin for WordPress to embed external content into my website. The plugin works great for displaying external pages and modifying iframe behavior, but I would like some advice regarding financial content integration.

I’m trying to embed information pages and live data from Coinmoneyhub

The goal is to display crypto-related information directly inside an iframe while keeping proper resizing, scrolling, and compatibility across browsers.

Questions:

• What is the best configuration for embedding external financial websites?

• Are there recommended settings to avoid iframe blocking or security restrictions?

• Is auto-resize supported when embedding dynamic crypto dashboards?

Any tips or working examples would be greatly appreciated.

Thank you in advance for your help!
