An iFrame consists of HTML tags, content URL or external page or platform, and other parameters to show the content on your website. In short, an iFrame is a technique to use HTML code to embed any content in your WordPress website without having to host it yourself. Using iFrame code in HTML to embed content generated by others is the safest way as it automatically eliminates copyright issues and does not hurt your website’s performance at all. Most website owners tend to embed content hosted by others on different platforms because it can increase their website engagement and boost their brand easily.
