The document appears to be a series of slides by Tim Kadlec on various technical SEO topics. Some key points covered include: - The benefits of AMP for page speed due to reduced payload and third party requests. However, AMP pages initially render slower due to asynchronous loading of custom elements. - Caching and pre-rendering pages on a CDN improves AMP performance versus loading from the main domain. - Google contributes the vast majority of code to the AMP Project and many see it as a way for Google to influence web standards. - Progressive Web Apps (PWAs) are discussed as an alternative to native apps that can provide app-like experiences through the browser.

3. Why is AMP on the CDN better?

81. Tim Kadlec | @tkadlec | #TechSEOBoost
• Caching images and fonts
• Restricting maximum image sizes
• Compressing images on the fly
• Uses HTTP/2 and HTTPS
• Strips out HTML comments
• Automates inclusion of resource hints such
as dns-prefetch and preconnect
• Pre-rendering the page on the server
