What is AMP - Definition
Why does the AMP feature matter?
What we understand by the word AMP HTML is actually a traditional HTML language with performance restrictions. Most HTML tags are the same as AMP HTML, but some have been replaced with tags specific to AMP HTML. For example, the img tag changed to the amp - img tag, which fully supports the srcset attribute even if the browser does not yet support it.
AMP is not just for websites.
You can also create emails, a newsletter, or ads, among other things. Google Ads also allows you to create their content using AMP. Google introduced this possibility to its service back in 2017
