UK Orders Google to Share Its Search Algorithm: What SEOs Need to Know

The UK's Competition and Markets Authority ordered Google to disclose how its search results are ranked and to enable data portability to select third parties, according to Search News Buzz Video Recap: Google Volatility, Bing AI Reporting Updates, UK Orders Google To Hand Over Its Search Ranking Algorithm & More published June 19, 2026. That order, combined with a stack of product updates across Google and Bing, made for one of the more consequential weeks in search in recent memory.

The week also brought continued Google Search ranking volatility, new AI Mode features for paid subscribers, significant Bing Webmaster Tools reporting upgrades, and a round of direct guidance from Google on topics ranging from LLMS.txt files to subfolder structure. There is a lot to unpack here.

The Details: What Was Announced This Week

UK CMA Orders Google to Open Up Its Algorithm

The biggest story is the CMA ruling. According to the Search Engine Roundtable recap, the UK's competition regulator ordered Google to share how it ranks search results and to allow data portability to some third parties. That is not a proposal or a consultation. That is a directive.

If enforced as described, this would be a historic move. Search ranking signals have been Google's most closely guarded trade secret for over two decades. Regulators requiring access to that logic would fundamentally change the balance of power between Google and the SEO industry.

Google Search Ranking Volatility Continues

The recap also noted typical and ongoing Google Search ranking volatility carrying into the week of June 19th. If you have been watching your rank tracking dashboard and seeing unexplained swings, you are not imagining things. The volatility has been persistent.

Google AI Mode Gets Information Agents — For a Fee

Google Search rolled out information agents inside AI Mode, but only to subscribers. This is the first confirmed paid gate on a core AI Mode feature, and it signals Google is actively testing a tiered search product. If you are advising clients on AI visibility, this layer now matters.

Bing Webmaster Tools Upgrades AI Performance Reporting

Bing Webmaster Tools released updates to its AI performance reports, adding intents, topics, citation share, and a compare feature, according to the recap. A separate update to country filters in those same performance reports is also coming. This is meaningful for anyone tracking AI-driven traffic in Bing — the reporting is getting more granular and more actionable.

Google Search Console Link Report Updated

Google Search Console's link report was finally updated, per the recap. If you have been frustrated by stale link data in GSC, this is worth checking. The report had been a known pain point for technical SEOs auditing backlink profiles.

Direct Guidance From Google on Several Technical Questions

Google addressed a few questions that come up constantly on the agency side. Here is what they said, according to the recap:

• LLMS.txt files will not help or hurt your Google Search rankings.
• HTML is the standard for SEO — not markdown files.
• There is no practical SEO difference between using a subfolder structure for a US-targeted site.
• For site moves, all domain variants should be added to the Change of Address tool.
• Google updated its documentation around site moves and domain variants.

Google also spoke on chunking, site signals, content, paywalls, and AI clicks at Google Search Central Live in Milan, which took place this week.

Why It Matters: What This Means for Your SEO Strategy

Let's start with the CMA ruling, because it is the one with the longest tail. Regulators compelling Google to share its ranking logic would be a shift that affects everyone — agencies, in-house teams, tool vendors, and publishers. I have been doing this long enough to know that even partial transparency into ranking signals would reshape how SEOs build strategies and how they justify their work to clients.

Whether Google complies fully, partially, or contests the order is still an open question. But the direction of travel is clear. Governments are no longer treating search as a black box that regulators stay away from. That has real implications for how much longer pure opacity is sustainable.

The Bing AI reporting upgrades are more immediately useful. Citation share in particular is something I pay close attention to. If Bing's AI surfaces your content but does not cite you, that is invisible traffic you are not measuring. The new reporting gives you a clearer picture of how your content performs inside AI-generated answers — not just in traditional organic results.

Google's confirmation that LLMS.txt will not help or hurt rankings is worth filing away. There has been noise in the community about whether adding an LLMS.txt file to your site would signal something useful to Google's crawlers. Google says no. Stop worrying about it and focus on HTML content that is clean, crawlable, and structured.

The paid gate on Google AI Mode's information agents is a slower-moving story but one to watch. If premium AI features start living behind a subscription, then AI visibility strategy splits in two: one for free AI search results and one for paid. That is a new wrinkle most content strategies have not accounted for yet.

What to Do Now

1. Log into Bing Webmaster Tools and check the updated AI performance reports. Look specifically at citation share for your top pages. If you are getting surfaced but not cited, you have a content optimization problem worth solving.
2. Verify your Google Search Console link report is pulling fresh data now that Google has updated it. If you have been working off stale numbers, re-pull your backlink data before making any link-building decisions.
3. If you have a site move pending or recently completed, revisit Google's updated documentation and make sure all domain variants are listed in the Change of Address tool. Missing a variant is a common mistake that delays full ranking recovery.
4. Remove LLMS.txt from your SEO task list. Google has been direct: it does not affect rankings. Redirect that time to improving your HTML structure and making sure your key pages are easily parseable by crawlers.
5. Watch the CMA ruling closely. You do not need to act on it today, but if you work with enterprise clients or do regulatory-adjacent SEO work, start a brief on what algorithmic transparency would mean for your reporting and strategy.

Background and Context: Why This Week Fits a Bigger Pattern

The CMA action does not come out of nowhere. Regulators in the EU, UK, and US have been circling Google's search dominance for years. The UK's Digital Markets, Competition and Consumers Act gave the CMA stronger tools to impose obligations on designated strategic market status firms. Google's search business fits that frame squarely.

On the AI side, the split between paid and free search experiences is a trend that has been building since Google introduced AI Overviews. The addition of subscriber-only information agents in AI Mode is consistent with a broader monetization push across AI-powered search features. Microsoft has been doing similar things with Copilot integrations inside Bing.

The Bing AI reporting upgrades also reflect something I have seen discussed more at conferences recently: measurement of AI-generated search visibility is still immature. Most rank tracking tools, including the tools agencies use daily, were built for the ten blue links era. Citation share and intent-level reporting inside Bing Webmaster Tools is a step toward filling that gap. AI visibility tracking is becoming a real category, not just a buzzword.

The ongoing Google ranking volatility is a constant backdrop to all of this. Sites are still seeing unexplained fluctuations, and there is no confirmed named update attached to the movement. If your clients are asking why rankings shifted this week, the honest answer is: Google keeps rolling, and the volatility is real and documented.

If you want a cleaner view of how your site is performing across both traditional rankings and AI-cited results, Aergos rank tracking surfaces both in one place — which makes weekly reporting like this a lot less stressful to walk clients through.
