Can noindex pages still pass PageRank and enhance crawling?

Why does Googlebot still crawl pages marked as noindex?

The noindex tag tells Google not to include a page in its index, but it doesn't instruct it to stop visiting the page. If a page regularly receives internal links, Googlebot considers it a part of the site's active architecture and continues to crawl it.

This distinction is crucial for e-commerce sites or blogs with pagination. Category pages 2, 3, 4 often contain products or articles that Google wouldn't discover through page 1 alone — especially if the number of displayed items is limited.

What does this change for content discovery?

A classic scenario: you have 200 products in a category, displayed in pages of 20. Without crawling pagination pages, Google will only see the first 20 products if you block access to subsequent pages or if they are never crawled.

With the noindex maintained and an active internal linking (links like “next page,” “previous,” or page numbers), Googlebot follows these links, discovers the remaining 180 products, and can index them individually if their URLs are crawlable and indexable.

Does this statement apply to all types of noindex?

Mueller specifically talks about pagination lists, not all noindex pages. Behavior can vary depending on whether the noindex page is orphaned, rarely linked, or instead present within the permanent linking structure of the site.

Google adjusts the crawl frequency based on the internal “popularity” of a URL. A pagination page regularly linked from indexed pages will be crawled more often than an isolated noindex page, infrequently updated and poorly linked.

• Noindex does not prevent crawling if the page is regularly found through active internal links
• Links present on these pages remain followed, allowing for deep content discovery
• Behavior varies based on the integration level of the page within the site's internal linking structure
• This mechanism is particularly relevant for e-commerce pagination and large blog archives

Is this statement consistent with field observations?

Yes, and it confirms what many of us have observed for years: noindex ≠ nofollow. Server logs show that Googlebot continues to visit well-linked noindex pages, sometimes at a frequency almost identical to that of equivalent indexed pages.

But — and this is where Mueller remains deliberately vague — nothing indicates that these pages pass PageRank in the same way. Google has always been evasive on this point. Tests show contradictory results depending on websites, sectors, and linking structure. [To be verified]

What nuances should be applied to this logic?

The phrasing “regularly found through internal links” is crucial. If your pagination pages are only accessible via JavaScript, or if they receive links only from other noindex pages, the allocated crawl budget will be drastically reduced.

Another point: Mueller does not mention value transmission. A noindex page can serve as a relay to discover content, but there's no guarantee it boosts the ranking of target pages like an indexed page with accumulated PageRank would. Real-world tests show diminished or even zero transmission in some cases. [To be verified]

What cases make this logic counterproductive?

If you multiply noindex pages within your architecture — combinatorial filters, sorting by price/date, minor category variations — you force Google to massively crawl URLs without indexable value. The crawl budget gets diluted, and strategic pages are visited less frequently.

Let’s be honest: many e-commerce sites have thousands of noindex pagination or filter pages that contribute nothing, as the products are already discoverable via shorter paths. In these cases, it’s better to completely block via robots.txt or disable links to save crawl budget.

What should you do concretely on a site with pagination?

First, ask yourself: do my pagination pages actually serve to discover content? If your categories display 10 products per page and you have 300, yes, absolutely. If you show 100 products per page and page 2 hardly ever exists, the debate is closed.

Then, check your server logs to see if Googlebot is actually crawling these pages. If they are noindex but never visited, it means they are poorly linked or Google has decided they aren't worth visiting. Adjust the linking or remove them from the equation.

What mistakes should be avoided in managing noindex on pagination?

A classic mistake: putting pagination pages in noindex but also in nofollow or blocking them via robots.txt. You completely cut off the discovery of deep content. Google no longer follows the links, and your products or articles on page 3+ will never be seen.

Another trap: using noindex on pagination pages that are the only access route to certain content. If a product only appears on page 12 of a category and has no direct link from the menu or sitemap, it will never be indexed if that page 12 is blocked or not crawled.

How can I check if this strategy works on my site?

Install a log analyzer (Botify, OnCrawl, Screaming Frog Log Analyzer) and filter the URLs containing your pagination parameters (“?page=”, “/page/2/”, etc.). Look at the crawl frequency, HTTP status, and discovery depth.

Then compare it with the indexing coverage of the products or articles listed on those pages. If you find that deep content is never indexed despite regular crawling of pagination pages, the problem lies elsewhere — perhaps a lack of internal popularity, a saturated crawl budget, or content deemed too weak.

• Maintain pagination pages in noindex, index-follow (or without explicit nofollow)
• Ensure that the internal linking to these pages is active and regular (links like “next page,” visible page numbers)
• Check in the server logs that Googlebot is effectively crawling these URLs with a reasonable frequency
• Audit the indexing coverage of listed deep content to confirm their discovery
• Avoid unnecessarily multiplying crawlable noindex pages if they do not contribute to discovery (redundant combinatorial filters, sorting without added value)
• Consider a comprehensive XML sitemap for strategic deep content, in addition to pagination linking
