Can AMP really replace your mobile site?

Why does Google advise against relying solely on AMP?

Google's stance is clear: AMP was never designed to be a standalone solution. The technical constraints of the framework are too limiting to meet the needs of a modern site.

This refers to strict JavaScript limitations, prohibitions on custom forms, CSS capped at 50 KB, and the inability to use certain third-party scripts. An AMP site cannot handle sophisticated e-commerce carts, interactive product configurators, or even a simple real-time customer chat.

What’s the difference between loading speed and a complete mobile experience?

AMP excels in one specific area: the initial loading time of static pages. The pre-rendering in Google's cache and enforced resource optimization yield measurable results on Core Web Vitals.

But speed is just one component of user experience. A high-performing mobile site must also offer rich features, smooth multi-step navigation, and complex interactions. Sacrificing all that to shave off 200 ms on the LCP is losing sight of the goal.

In what context does AMP still hold strategic value?

Google is not saying to abandon AMP. It suggests positioning it as a temporary booster for simple editorial content: blog articles, news pages, basic product sheets.

The effective strategy is to maintain an AMP version for critical entry points — those benefiting from the Top Stories carousel or targeting audiences on slow mobile networks — while keeping the classic mobile site as the main foundation.

• AMP is not a technical substitute for a complete responsive mobile site
• The framework restrictions (JS, CSS, third-party scripts) block advanced features
• Loading speed does not justify sacrificing interactive capabilities
• The hybrid approach (AMP + standard mobile site) remains the most defendable for editorial content
• Google itself positions AMP as a complement, not as a sole solution

Does this statement reflect on-the-ground observations?

Absolutely. In practice, sites that attempted an AMP-only migration have all had to revert. E-commerce cases that tried to push AMP on their product listings quickly encountered the impossibility of integrating basic business functionalities.

Publishers who heavily invested in AMP around 2018-2019 have gradually abandoned or limited its use to simple articles. The ROI does not follow when investing heavily in a framework that limits engagement and conversions.

What nuances should we consider regarding this official position?

Google does not mention a crucial point: AMP's historical advantage in mobile SERPs has significantly diminished. The Top Stories carousel has not required AMP since 2021, and Core Web Vitals have become the real criteria for differentiation. [To be verified] in certain geographic markets where AMP may still provide some residual boost, but no official data supports this.

Another point: Google speaks of "restrictions" without ever quantifying their actual impact on conversion rates or engagement. An AMP site can have a bounce rate 20-30% higher than an optimized mobile site offering rich pathways, but Google never shares these business metrics.

When does this rule not really apply?

Let’s be honest: if your site is strictly informational without interaction — institutional pages, basic corporate blogs, showcase sites — AMP can technically cover 100% of your needs. But this is a marginal case.

For 90% of modern web projects, even a simple contact form requires scripts that AMP does not allow without workarounds. Google's rule applies to the overwhelming majority of real cases.

What should you do with AMP today?

First step: audit the real contribution of your current AMP pages. Compare engagement metrics (time spent, bounce rate, conversions) between AMP versions and standard mobile versions. If the AMP shows a bounce rate higher by 15% or more, that’s a clear signal.

Next, identify the content still benefiting from a measurable boost: editorial articles in Top Stories, pages with very high organic mobile traffic. Maintain AMP only for these segments, and switch the rest to a high-performing classic mobile site.

What mistakes should you avoid in your mobile strategy?

A classic mistake: believing that AMP makes it unnecessary to optimize the main mobile site. A slow mobile site will remain an issue even if you offer an AMP version. Google primarily crawls and indexes the standard mobile version; it's this version that affects your ranking.

Another trap: investing heavily in AMP development when your classic mobile site could achieve equivalent performance with good optimization work (lazy loading, compression, CDN, minification). The cost of maintaining two parallel versions is only justified if the gain is documented.

How can you verify that your mobile approach aligns with Google's expectations?

Use PageSpeed Insights and Core Web Vitals as your main reference. If your standard mobile site achieves green scores (LCP < 2.5s, FID < 100ms, CLS < 0.1), AMP likely doesn’t provide anything decisive.

Also, test the actual user experience: a smooth mobile journey with all available features will always outperform an ultra-fast but limited AMP page. Search Console and Google Analytics data will give you the quantified answer.

• Audit comparative performances AMP vs standard mobile on your priority content
• Measure actual engagement (bounce rate, time spent, conversions) on each version
• Maintain AMP only on segments with proven ROI (editorial, Top Stories)
• Prioritize investment in optimizing the main mobile site
• Check the Core Web Vitals of the mobile site as a decision criterion
• Stop all AMP development if the mobile site already achieves optimal performance
