Search Engine Roundtable reported on 31 July 2026 that Google's John Mueller told Google's Martin Splitt, on the latest episode of the Search Off the Record podcast, that blocking Google from internal site-search result pages is no longer listed in Google Search Essentials, the documentation that used to be called the Webmaster Guidelines. Mueller said he still thinks blocking those pages makes sense, but for technical reasons rather than because a policy requires it. The exchange sits at the 17:10 mark of the video.
What John Mueller said on Search Off the Record
Speaking to Martin Splitt on the podcast episode covered by Search Engine Roundtable on 31 July 2026, Mueller traced the rule back to where it started. In his words: "back in the early days in our webmaster guidelines, when they existed as Webmaster Guidelines, I think we also listed search results pages as something that you have to block from Google."
He then gave the reasoning Google used at the time: "And we listed it, I think, either as automatically generated content or something like these infinite spaces type things, because theoretically, it's an automatically generated content. It's also infinite space." Google added that guidance to its documentation in 2007.
Google dropped the line, not the advice
Mueller was direct about the current state of the documentation on the same 31 July 2026 podcast coverage: "Nowadays, we don't have that listed in the search policies, but it's still something that I think just purely for technical reasons makes sense. So it's not necessarily something where we would say, 'We think your site is spam if you allow your search results pages to be indexed.' It's just like, you're being very inefficient."
So the practical instruction has not moved. What moved is the justification behind it. Google still recommends blocking these pages for other documented reasons, including watering the site down, creating low-quality pages and generating soft 404s, and the advice remains part of Google's guidance on preventing spam on a site. Anyone treating the removal as permission to open internal search results to crawlers is reading it backwards.
How the guidance changed between 2007 and now
The table below sets the old Webmaster Guidelines position against the current Search Essentials position.
| Aspect | Old Webmaster Guidelines | Search Essentials today |
|---|---|---|
| Listed in the documentation | Yes, added in 2007 | No, not listed in the search policies |
| How it was classified | Automatically generated content, or an infinite space | Not classified in the policy |
| Treated as spam | Framed as pages you have to block | Mueller: Google would not say the site is spam |
| Google's recommendation | Block internal search result pages | Still recommended, for watering the site down, low-quality pages and soft 404s |
Risk one: crawling that slows down the rest of the site
The first risk Mueller named on the 31 July 2026 podcast is plain inefficiency and server load, and he noted it may also affect how fast Google crawls the rest of your site. An internal search box can generate an unbounded number of URLs, and every request Googlebot spends on one of them is a request it did not spend on a product or service page.
Risk two: a hacked flag in Search Console
The second risk is what happens when strangers use your search box as a publishing tool. Mueller put it this way: "if you let people search for things that are totally irrelevant to your website, and your search results page includes those terms on those search results page and is indexable." He went on: "But you could imagine casinos, pharmaceuticals, any kind of restricted content, any adult-related content."
The consequence he named is specific. Google might flag that as hacked when it spots the pattern, and in Mueller's words, "So in Search Console, you might see that as something that is flagged as hacked." Barry Schwartz noted in the 31 July 2026 write-up that this can bring a downgrade in rankings while the hack status is in place, and that Mueller stressed it is not literally a hack, because as Mueller put it, "your website is doing that freely".
What this means for Thai marketers
Neither Google nor Search Engine Roundtable said anything about Thailand here, so treat the following as reasoning rather than reporting. Internal search is standard on Thai e-commerce catalogues, property portals and classifieds, and those templates frequently expose a clean, linkable results URL with the query in the path. A Thai-language search box produces the same infinite space as an English one, and a URL carrying Thai characters is no harder to fill with casino terms.
The practical check is small. Look at whether your search results template is crawlable, whether those URLs appear in Search Console coverage reports, and whether the query string is echoed back into an indexable page. A technical SEO audit normally surfaces this at the same time as soft 404s and thin pages, since they tend to come from the same templates. If the pattern is present, the fix belongs with whoever owns the templates, which usually means the web design or development side rather than the content team.
Frequently asked questions
Can I let Google index my internal search pages now that the rule is gone?
You can, but Mueller said on the podcast reported on 31 July 2026 that doing so makes a site very inefficient, and Google still recommends blocking those pages. The line left the documentation. The reasons to block did not.
Is this a Google algorithm update?
No, this is a documentation change, not an algorithm update and not a new penalty. Mueller said Google would not call a site spam for allowing search result pages to be indexed.
Can indexed search pages really get my site flagged as hacked?
Mueller said Google might flag a site as hacked when irrelevant searches, such as casinos or pharmaceuticals, end up on an indexable results page. Schwartz noted this can come with a ranking downgrade while the flag is active, and Mueller stressed the site is not actually hacked.
Does this apply differently to sites in Thailand?
The source does not say. Neither Mueller nor the Search Engine Roundtable report mentioned any country-specific treatment, and Search Essentials is global documentation rather than a per-market policy.
The removal of a line from Google's documentation rarely changes what a site should actually do. If you want your own templates checked for crawlable search pages, the SEO team at Relevant Audience can take a look.
