Should you really eliminate 'Read more' buttons to please Google?

Why does Google emphasize visible text at loading?

Google's stance is based on a simple logic: a user landing on a page should be able to scan the content immediately, without friction. 'Read more' buttons or closed accordions introduce an extra step that slows down information consumption.

Mueller does not state that hidden content will be ignored by the crawl. He mentions that user experience suffers, and it is this degradation that can indirectly impact ranking. A frustrated visitor might bounce quicker, reduce their session time, or never scroll down to the call-to-action — all of which send negative signals to the ranking algorithms.

Is content hidden behind a button always indexed?

Yes, in most cases. Google crawls and indexes content available in the DOM, even if it requires a click to appear. Field tests show that accordions or tabs do not block indexing, especially since Googlebot executes JavaScript quite robustly.

However, the semantic weight afforded to this content may be lower than that of content displayed immediately. Google has always prioritized content that is 'above the fold' or visible without interaction — this has been consistent for years. So yes, your text will be indexed, but it might not receive the same boost as if it were visible from the first render.

Does this recommendation apply to all types of pages?

No, and that’s where nuance comes into play. E-commerce category pages with lengthy product descriptions, structured FAQ accordions, mobile-first pages optimizing vertical space — all these legitimate cases use hidden content patterns without penalizing their ranking.

The key lies in user intent and the design pattern adopted. A well-designed accordion with clear headings can even enhance UX compared to a wall of unreadable text. Google knows this. What Mueller points out is the misuse: hiding essential content to force a click, or concealing critical information out of design laziness.

• Hidden content remains indexable, but its semantic weight may be diminished.
• UX is paramount: a page difficult to read or navigate indirectly impacts behavioral signals.
• Some patterns (FAQ accordions, product tabs) are legitimate and won't penalize if executed well.
• Mobile complicates matters: limited vertical space sometimes justifies hiding secondary content.
• Google values immediately visible content, especially for informational queries.

Is this statement consistent with field observations?

Overall, yes. The tests I conducted on e-commerce and media sites show that visible content at loading performs better in terms of organic CTR and session time. Pages where the essential information is hidden behind multiple clicks tend to underperform, even if they rank.

But be careful: this correlation does not imply direct causation. It's not Google that degrades ranking because you use a 'Read more' button. It's the degraded user experience that generates negative signals (bounce rate, low dwell time) that the algorithm picks up. [To be verified]: Google has never published quantified data on the real impact of these patterns on ranking — we remain in the realm of interpreting observed behaviors.

What nuances should be added to this recommendation?

First, the mobile context changes everything. On smartphones, hiding secondary content behind an accordion is often the best UX solution to avoid endless scrolling. Google knows this, and its mobile-first index does not penalize these choices when justified.

Furthermore, some types of content benefit from being structured in tabs or accordions: FAQs, comparison tables, complex product sheets. If your design allows for clear navigation and users quickly find what they’re looking for, you won’t be penalized. The problem arises when you hide essential content necessary for page understanding — there, you're playing with fire.

In what cases does this rule not apply?

Single Page Applications (SPA) and sites with complex navigation (configurators, dashboards) often rely on dynamic content patterns. Google has made strides in crawling JavaScript, but if your critical content is only accessible after several user interactions, you risk under-indexation.

Another case: very long pages (guides over 5000 words, detailed case studies). Here, a 'Read more' button or an interactive table of contents can enhance UX without harming SEO, provided the content is well-structured with anchors and that crawling is not blocked. Let’s be honest: no one wants to scroll through 10 screens on mobile to reach a conclusion.

What should you concretely do on your existing pages?

Start with an audit of content patterns on your key pages (landing pages, product sheets, blog articles). Identify where you’re using 'Read more' buttons, accordions, or tabs. Then, ask yourself: is this hidden content essential to meet search intent?

If yes, make it visible upon loading. If it’s secondary content (technical details, advanced specs, ancillary FAQs), maintain your pattern but optimize the button or accordion label to be explicit. A user should immediately understand what lies behind the click.

What mistakes should be absolutely avoided?

Never hide your main content behind a click if this content directly answers the target query. For example, on a page 'How to install X', if the complete tutorial is hidden behind a button, you're sabotaging your potential ranking.

Another classic mistake: using default closed accordions on desktop when you have plenty of space to display the text. That’s a total waste. Reserve these patterns for mobile, where vertical space is a real constraint. On desktop, prefer an airy layout with visible content, even if it means using a sidebar or well-defined sections.

How can I check that my site meets Google's expectations?

Use Search Console to verify page rendering — compare the version crawled by Googlebot to what a real user sees. If discrepancies appear (content absent in the bot's rendering), that's a red flag.

Conduct user tests or analyze your heatmaps (Hotjar, Crazy Egg): do visitors scroll down to hidden content? Do they click on 'Read more' buttons? If the click rate is low, your UX pattern isn’t working — and Google will capture these weak engagement signals.

• Audit strategic pages and identify any essential content hidden behind a click.
• Make the main content visible upon loading, especially on informational pages.
• Reserve accordions and tabs for secondary content or mobile contexts where space is constrained.
• Test Googlebot rendering vs. real user via Search Console and compare mobile/desktop versions.
• Analyze behavioral signals (bounce rate, session time) on pages with hidden content.
• Optimize button and accordion labels to be explicit and engaging.
