概要

AMP (Accelerated Mobile Pages) is Google's framework for mobile web performance. Pages load in <1 second, use 10x less bandwidth, work offline. Learning takes 2-3 weeks (HTML/CSS/JavaScript constraints + component library). Declining in adoption (2026: AMP usage plateauing), but critical for publishers, news sites, and e-commerce in emerging markets where bandwidth is scarce.

AMP Progressive Webとは

AMP (Accelerated Mobile Pages) is Google's open-source framework for building web pages that are lightning-fast on mobile. AMP pages load in <1 second, use 90% less data, and work offline. AMP achieves this through constraints: no synchronous JavaScript, CSS limited to 75KB, all resources must specify dimensions, lazy-loading by default. AMP HTML is a restricted subset of HTML. You write pages in AMP HTML, use AMP components (amp-img, amp-carousel, amp-form), and Google distributes AMP pages through its CDN for instant delivery.

❓ よくある質問

What's AMP and is it still relevant in 2026?

AMP is Google's framework for ultra-fast mobile pages. It constrained HTML/CSS/JS to guarantee sub-second load times. Relevant if: you publish news/content and need SEO, you serve emerging markets with slow networks. Less relevant if: you build SPAs, focus on desktop, user base has fast connections. Declining adoption.

What are AMP's constraints and why do they exist?

No custom JavaScript (only AMP JS), restricted CSS size (75KB), asynchronous loading of resources, all images must have dimensions. Constraints guarantee predictable performance. Without them, publishers would add tracking pixels, auto-playing videos, bloated ads = slow pages.

Is AMP better than Next.js or other modern frameworks?

Different use cases. AMP = extreme performance guarantee for publishers. Next.js = flexible SPA/SSR framework. AMP is 100ms faster on mobile but less flexible. For news sites, AMP wins. For apps, Next.js wins.

Does Google still prioritize AMP in search rankings?

No. As of 2021, Core Web Vitals (LCP, FID, CLS) matter more than AMP badge. Fast non-AMP pages rank same as AMP pages. AMP is no longer a ranking boost, just a way to guarantee performance.

Can I use AMP for e-commerce?

Partially. AMP works for product listing pages, detail pages, checkout. But cart logic and user interactions are limited by AMP constraints. Hybrid approach: AMP for listing, transition to regular web app for checkout.

What's the learning curve for someone from React?

Steep in the wrong direction. AMP is declarative HTML, no state management, no components. React devs find it restrictive. But learning AMP teaches performance thinking: what constraints guarantee speed? This mindset transfers to any framework.

What's the future of AMP?

Stabilizing, not growing. Publishers still use it. Startups rarely adopt. Google still maintains it but investment is lower. If you're learning AMP, learn for specific job (publisher, news site) not as a primary skill.
