Official statement

Using tabbed systems on a web page to display diverse content is not recommended for rel=next/prev, as this is ideal for paginated content. It is better to keep each tab as a separate URL. This way, each section can be indexed correctly by Google, especially if a section has relevant content on its own.

TL;DR

Google clearly advises against using tabs to organize distinct content on the same URL. The technical reason is that each section hidden behind a tab may be poorly indexed or ignored by the search engine. The recommended solution is to create a unique URL for each section, ensuring that each block of content can be crawled, indexed, and ranked independently.

What you need to understand

Why does Google warn against tabbed systems?

Tabbed systems are widely used to condense information and enhance user experience. The issue is that Google does not guarantee the indexing of content hidden by default in these tabs.

Unlike content that is immediately visible, text hidden behind an inactive tab may be undervalued or simply ignored during crawling. This is not an absolute rule, but the risk exists, and Google prefers not to take chances.

What is rel=next/prev and why doesn't it work here?

The rel=next/prev attribute was designed to signal to Google the logical pagination of content split across multiple pages. For instance, an article cut into three distinct pages could be signaled as a coherent sequence.

But be careful: Google officially dropped support for this attribute several years ago. Even though some practitioners continue to use it out of habit, it no longer has any technical effect on indexing. Confusing tabs with pagination is a conceptual error: tabs are not successive pages, they are blocks of parallel content on the same URL.

What is the solution recommended by Google?

Mueller is unequivocal: each tab should have its own distinct URL. This allows Google to treat each section as an independently indexable entity, with its own ranking potential.

Specifically, instead of having a single URL with three tabs (Reviews, Features, Price), you should create three separate URLs, each targeting a specific aspect of the content. This is cleaner for SEO, clearer for the user, and much easier to audit.

  • Tabs hide content that may be under-indexed or ignored by Google
  • rel=next/prev only applies to pagination, not to tabs, and is outdated anyway
  • Each important section should have its own URL to maximize indexing chances
  • This approach facilitates analytics tracking and allows for finer internal linking
  • Separate URLs offer more flexibility for long-tail strategies

SEO Expert opinion

Is this recommendation consistent with field observations?

Let's be honest: tabs do not always pose a problem. Many sites use tabs with content indexed correctly, especially if the JavaScript code loads the content in an accessible manner for the crawler. Google is fully capable of interpreting modern JS, and content hidden behind a tab is not automatically blacklisted.

The issue arises when the content of the tabs is loaded via late AJAX, not present in the initial HTML, or structured in a way that Googlebot has to simulate multiple user interactions. In these cases, the risk of partial indexing is real. But a tab based on pure CSS with all content in the DOM? No major technical issues.

What nuances should be added to this directive?

Mueller talks about a case where each tab contains relevant content on its own. That’s the key. If your tabs are just minor variations or secondary details, creating a URL for each tab is a waste of crawl budget and leads to artificial page inflation.

On the other hand, if each tab addresses a distinct search intent, then yes, separating makes sense. A "Customer Reviews" tab can target "product X reviews", while a "Specifications" tab might aim for "product X technical sheet". These are two different queries, hence two justified URLs. [To be verified]: Google has never published a threshold of volume or complexity from which tabs become problematic.

In which cases does this rule not apply?

If you are using tabs to structure small variations of the same content, like product sizes or colors, do not create a URL for each tab. You risk keyword cannibalization and dilution of your internal PageRank.

Similarly, on mobile, tabs are often replaced by accordions or stacked content. In this case, the content is entirely in the DOM, just collapsed by default. Google indexes this type of layout perfectly. Mueller’s directive mainly targets complex architectures where content remains inaccessible without interaction.

Warning: if you migrate from a tabbed architecture to separate URLs, carefully prepare your redirects and internal linking. A hasty migration can lead to temporary or permanent traffic loss.

Practical impact and recommendations

What should you do concretely on an existing site?

First, audit all pages using tabs. Identify those where the tab content is substantial, unique, and meets distinct search intents. For each, ask yourself: does this content deserve its own URL?

Next, check how the content of the tabs is loaded. If it's JS that injects text after a click, test with the Search Console (URL inspection) to see if Google retrieves all the content correctly. If not, you have a confirmed indexing issue.

What mistakes to avoid during the redesign?

Do not create separate URLs if the content is too thin or redundant. You risk diluting your authority and creating duplicate or semi-duplicate content. Google does not like weak pages artificially multiplied.

Another classic trap: forgetting to update the internal linking after migration. If your old tab URLs had internal links, redirect properly and redistribute those links to the new URLs. Otherwise, you will foolishly lose SEO juice.

How to verify that your new setup works?

After migration, follow the indexing of new URLs via the Search Console. Check that each page is receiving impressions for distinct and relevant queries. If all your URLs are cannibalizing the same query, it means the separation was not justified.

Also analyze the bounce rate and time spent on each new page. If users flee immediately, it may be that the segmentation is too aggressive and harms the experience. SEO is not just about indexing: UX remains crucial.

  • Audit pages with tabs and assess the SEO potential of each section
  • Test the indexing of hidden content with the URL inspection tool in Search Console
  • Create distinct URLs only if the content is substantial and meets a specific intent
  • Implement clean 301 redirects if migrating from a tabbed architecture
  • Reorganize internal linking to point to the new URLs consistently
  • Monitor performance in Search Console to detect any cannibalization or traffic loss
These technical adjustments may seem simple on paper, but their implementation requires a thorough analysis of the existing architecture and migration risks. If your site heavily relies on tabs or if you fear losing traffic during the transition, consulting an experienced SEO agency can help you avoid costly mistakes and ensure a controlled redesign, with rigorous performance monitoring before, during, and after.

❓ Frequently Asked Questions

Le contenu derrière un onglet est-il vraiment ignoré par Google ?
Pas systématiquement. Si le contenu est dans le DOM initial et accessible sans interaction JS complexe, Google peut l'indexer. Mais le risque augmente avec les chargements AJAX tardifs ou les implémentations JS mal optimisées.
Peut-on utiliser rel=next/prev pour des onglets ?
Non, et de toute façon rel=next/prev est obsolète depuis plusieurs années. Cet attribut servait à signaler la pagination, pas les onglets, et Google ne le prend plus en compte.
Faut-il créer une URL par onglet même pour des détails mineurs ?
Non, uniquement si chaque onglet contient du contenu substantiel et répond à une intention de recherche distincte. Sinon, vous risquez la cannibalisation et la dilution de votre autorité.
Comment tester si mes onglets sont bien indexés ?
Utilisez l'outil d'inspection d'URL de la Search Console pour voir le rendu HTML tel que Google le voit. Si le contenu des onglets n'apparaît pas, vous avez un problème d'indexation.
Que faire si je ne peux pas créer d'URLs séparées pour des raisons techniques ?
Assurez-vous que tout le contenu des onglets est présent dans le HTML initial, même s'il est masqué par CSS. Évitez les chargements AJAX différés pour le contenu critique et testez régulièrement l'indexation.
