Standard vs AMP landing pages
AMP is an open source web framework by Google. Search results in Google ( as well as Bing ) like the one shown in the example below, that have the flash symbol next to them are AMP pages.
Some of the restrictions of AMP pages are
1. 75KB of CSS per page
2. No External CSS files
But don't fret if you don't know what this means. We have tried to bring almost all the functionality that we have in our standard pages to AMP. We have built custom AMP components so that you don't have to.
Both AMP and Standard pages are fully responsive, meaning the design adapts to all screen sizes from Desktops down to Tablets & Mobile.
Instant loading that you get from AMP is a magical feeling and is the Google recommended way. You are rewarded with higher ad quality scores ( assuming your page ticks other boxes like content, relevancy, design etc ) and could mean lower CPC's. But don't let the word "Standard" deceive you. They are equally optimized and are really fast and offer the best balance between customizability and performance.
