What AMP Does for Mobile Pages

AMP enforces a strict set of rules for HTML, CSS and JavaScript. The goal is to make pages load almost instantly on mobile devices.

AMP pages are often served from a cache, such as the Google AMP Cache, which further speeds delivery. This caching can also reduce server load.

For example, a news article with multiple images can load in under a second on AMP because images are lazy-loaded and JavaScript is async. A standard page with the same content might take several seconds. The AMP framework also restricts third-party scripts, which are a common cause of slow loading. By limiting what can run on the page, AMP ensures that only essential components are loaded first.

  • No custom JavaScript; only AMP-approved components.
  • CSS is limited to 50 KB and must be inline.
  • Use of async scripts to prevent blocking.
  • Images and videos are lazy-loaded by default.

How AMP Affects SEO Today

Google has stated that AMP is not a direct ranking factor. However, it can improve load time and user experience, which are part of Google's page experience ranking signals.

AMP pages can appear in special features like Top Stories carousel, though this is not guaranteed. For SEO, the main benefit is faster mobile pages.

AMP SEO is about using the framework to improve mobile performance, not about a direct ranking boost. Google's official position is that AMP is not a ranking factor, but speed and user experience matter. AMP can help achieve those goals.

For instance, a site that implements AMP may see lower bounce rates on mobile because pages load faster. This improved engagement can indirectly signal quality to Google. However, if the content is poor, AMP alone will not help rankings. The key is to use AMP as a tool for performance, not as a shortcut to higher positions. Many SEOs debate whether AMP is still relevant, but for news publishers it remains a practical way to meet Google's speed expectations.

When to Use AMP

AMP is best suited for content-heavy sites like news and blogs where speed is critical. It can also work for e-commerce product pages, but interactive features may be limited.

Common Implementation Mistakes

Many sites implement AMP incorrectly. Common errors include missing rel="canonical" or rel="amphtml" tags, which can confuse search engines.

Another mistake is using too much custom CSS, which exceeds the 50 KB limit and causes validation failures. Also, ignoring AMP validation can lead to pages that are not indexed or shown as AMP.

For example, a site might add AMP pages without linking them to the canonical version. This creates duplicate content issues because search engines see two separate pages with the same content. Another example is using a large CSS framework that generates over 50 KB of inline styles. The AMP validator will reject the page, and it will not be served from the AMP cache. Regularly running the AMP validator during development can catch these issues early.

  • Missing or incorrect rel="canonical" and rel="amphtml" tags: search engines may index the wrong version.
  • Exceeding the CSS size limit: AMP validation fails, and the page may not be served as AMP.
  • Ignoring AMP validation errors: the page may not appear in AMP-specific features or be cached properly.
