Google Adds Social Reporting; Mueller Warns About Markdown

Welcome to Pulse of the week: updates on what you can measure in the search console, how to describe products in markup, and what John Mueller thinks about building AI agents.
Here is what is important to you and your work.
Search Console Adds Social and Video Post Reports
Google is introducing a new type of Search Console property, called platform properties, that reports how your social posts and videos are performing in Search and Discover.
Important facts:
The report includes Instagram, TikTok, X, and YouTube, even if you don’t have a website. Each platform offers three dedicated post reports. The Performance Report includes click data, impressions, filtering, and export options. Insights highlights recent traffic and top posts, while achievements mark milestones such as exceeding click limits in 28 days.
Why This Matters
Until now, Search Console data was limited to sites you could verify. This update extends reporting to posts on Instagram, TikTok, X, and YouTube, allowing you to see which queries are driving traffic to your posts in Search and how those posts are performing across all Google sites.
What SEO Experts Say:
The launch received a strong response from people who work in Search every day. SEO and AI Search consultant Aleyda Solís, in a post that has attracted more than 350 reactions, used it to argue that SEO is now reaching your site:
With this release Google is doing something obvious that many in our industry still resist: Your SEO doesn’t start and end with Google or your website. Search discovery is different and SEO is all about optimizing where your audience is searching for you.
SEO consultant Brodie Clark, who had quick access to previous research, said the data proved useful ahead of a wider rollout:
On the one site I have access to trial social media (YouTube), I found the data particularly useful – so it’s good to see this is now official!
Technical SEO manager Simone De Palma accepts but wants data from APIs and pipelines, not just connections:
That’s a good step, but I’d like to see it reflected in the API and data pipelines as well.

Google Revises Its Database Structured List of Sellers
Google has updated the structured data documentation for seller listings in two areas: one on how to set a product category and one on how to set a sale price.
Important facts:
Two updates worth noting: Google now provides documentation for the ‘category’ location in seller listing tags, which includes a way to specify a start and end sale price. Its use is recommended but not mandatory.
Why This Matters
The category attribute provides an easy way to specify product classification at the page level, matching the existing product category and google_product_category attributes from your Merchant Center feed.
If the plugin is creating your tag, check if it supports the category structure and Google’s current selling price guidelines. Nothing breaks if it doesn’t, so treat this as a line item for your next markup update.

Mueller Says Don’t Build Separate AI Comment Pages
Search attorney John Mueller has pushed back against the practice of mirroring HTML pages with markup versions built for AI agents, responding to a Bluesky post about making sites accessible to machines.
Important facts:
The discussion began with a post highlighting that some sites now provide a text version of LLMs, yet they still neglect accessibility essentials such as proper subject structure and landmarks used by screen-reading users. Mueller responded that a well-designed website naturally works for AI agents, search engines, LLMs, and most importantly, people. Adding a different, agent-friendly version can lead to technical debt that will eventually need to be redeveloped.
Why This Matters
Mueller’s answer is a warning against creating a second, automated version of your site. His point is that unique copy becomes a technical liability to maintain, while a well-designed HTML page already works for search engines, LLMs, and people at the same time.
For your road, weigh the markup mirrors and llms.txt files against modifying the HTML you already have before you waste time. Mueller and Martin Splitt made a similar case back in June, warning that a parallel download version is something to keep and that a broken page with only a machine has no user to flag.

Google Says Search Hits Record Usage During World Cup
Google says Search saw its highest usage in history during Argentina’s comeback win over Egypt in the World Cup.
Important facts:
Nick Fox from Google shared this on X, although he didn’t provide published statistics or a detailed blog post. A claim relates a peak to a single live event rather than a fixed trend.
Why This Matters
During major live events such as the return of the World Cup, election night, or to break newspeople keep turning to Google for real-time updates. That habit of turning to Search first when the numbers are high and the clock is ticking hasn’t gone anywhere. Live sessions are still earned in Search

Theme of the Week: More Space, One Place to Save
Each update this week adds a place where your content is rated or explained, while pointing back to the same source.
Google has included social and video posts within Search Console, so content from Instagram, TikTok, X, and YouTube now appears in Search and Discover reporting. New category documents give your product pages a page-level way to specify their classification. Mueller’s answer to markdown runs in the opposite direction, arguing for a second machine version of your site and a well-designed single page that serves both humans and machines at the same time.
The number of places where your content is coming from keeps growing, but what you’re saving shouldn’t. This week is about measuring and marking one precise version of your site right, not flipping the corresponding copy for every reader, person or machine.
