SEOCode Update 1.6.3: Four Things That Changed on Google This Week
Version 1.6.3 adds four new checks to keep you informed about recent changes on Google's side and in the wider SEO world that could affect how your site performs in search.
None of these checks require you to fix broken code. They are awareness checks. That means SEOCode flags them so you know they exist and can decide whether to act.
New Checks
Google's European Ecosystem Carousel Is Now Live
What it is. Google has turned on a new feature in European search results called the European Ecosystem Carousel. It shows up for searches about things like weather and translations. Think of it as a row of cards that appears at the top of Google's results page for certain types of searches.
Why it matters. If your site targets users in Europe and you rely on traffic from searches about weather, translations, or similar topics, this carousel could push your result further down the page. Fewer people may click through to your site even if you rank well, because Google is answering the question right there in the results.
What you should do. You do not need to add any special code to your site. Google runs this carousel using its own data. But if you run a site in one of these topic areas and you serve European visitors, it is worth watching your click-through rate (the share of people who see your site in results and actually click on it) over the coming weeks.
Google's Performance Data Now Includes Ad Metrics
What it is. Google runs a big public dataset called the Chrome User Experience Report, or CrUX for short. It collects real data about how fast websites load for real users. Google uses this data as part of how it decides where to rank pages. CrUX now includes data about how ads on a page perform, alongside the existing speed and experience data.
Why it matters. Tools you may already use, like Google Search Console and PageSpeed Insights, pull from CrUX. If your site shows ads, the way those ads load and behave is now part of the picture. It is not yet clear exactly how ad metrics will feed into rankings, but the data is there and tools will start surfacing it.
What you should do. If your site runs ads, keep an eye on your Core Web Vitals scores (these are Google's measures of page speed and user experience) in Google Search Console. If your scores drop, ads could be a contributing factor worth investigating.
Schema.org 30.1 Adds New Vocabulary for Shops and EU Product Passports
What it is. Schema.org is a shared language that website owners use to label information on their pages so Google can understand it better. Think of it like putting a label on a jar so anyone can read it at a glance. Version 30.1 of schema.org added two new areas of vocabulary.
The first area is for online shops. New labels were added for shipping rates and price types. If you run a shop and you send product data to Google's Merchant Center (a tool that lets your products appear in Google Shopping), these new labels help your data line up more cleanly with what Google expects.
The second area is for EU Digital Product Passports. The EU is bringing in new rules under a regulation called the Ecodesign for Sustainable Products Regulation, or ESPR. These rules will require certain products sold in Europe to have a Digital Product Passport, which is a record of a product's environmental impact, materials, and lifecycle. Schema.org 30.1 adds a new set of labels so websites can point to these passports in a way that Google and other systems can read.
What you should do.
- If you run an online shop, check whether your product data uses the new shipping and pricing labels. This is most relevant if you use Google Merchant Center.
- If you sell physical products in the EU and the ESPR rules apply to your product category, talk to your developer about the new Digital Product Passport vocabulary. Getting this in place early is a good idea.
AI Tools Like ChatGPT and Claude Can Now Work Directly With SEO Data
What it is. There is a standard called MCP, which stands for Model Context Protocol. It is a way for AI tools (like ChatGPT or Claude) to connect to outside data sources and take actions based on that data. Botify, an enterprise SEO platform, has confirmed that its MCP integration is now live and working inside ChatGPT, Claude, and other major AI tools.
Why it matters. This is a sign that AI agents (software that can carry out tasks on your behalf inside an AI tool) can now pull in real SEO data, like how a site is being crawled by Google, and work with it directly inside a chat interface. This is no longer a future idea. It is happening now.
What you should do. If you use AI tools in your day-to-day work and you want them to be able to access and act on your site's SEO data, MCP is worth looking into sooner rather than later. Ask your developer or SEO team whether your site or tools support MCP connections.
