Google Introduces Custom Annotations in Search Console

Executive Signal Summary

Google has added Custom Annotations to the Performance reports in Google Search Console, enabling SEO teams to annotate factors that influence traffic and rankings directly within performance charts. The feature acts as a personal SEO notebook, allowing notes about events such as core updates, content strategy changes, agency work, site migrations, holidays, or campaigns, tied to specific date ranges. Annotations appear as reference points in the Performance chart and are visible to all users with access to the property. To add an annotation, users can right-click in the Performance diagram, select a date, and enter a note limited to 120 characters. Hanns Kronenberg, Head of SEO at Chefkoch, referenced the feature on LinkedIn and discussed potential use cases like AI-related changes and canonical updates. This update enhances documentation of context around search performance for SEO teams.

Google Adds AI-Powered Search Console Configuration

Google is testing a new AI-powered feature inside Search Console that lets SEOs configure and retrieve performance reports through natural-language prompts. In the experimental setup, users can open an AI-powered configuration panel on the right edge of the interface, next to the existing filters, and ask for data tailored to specific queries or time periods. For example, a prompt like “Show the CTR of queries containing ‘how to’ or ‘what is’ in Canada last week” prompts the tool to generate the corresponding Performance reports with automatically applied filters and settings. This capability follows Google's Custom Annotations and aims to streamline data discovery for SEO work by reducing manual search and drill-down. The feature was announced by Google's Search Central Account on LinkedIn and may not be immediately available to all users. The article from OnlineMarketing.de presents the capability as a productivity boost for SEO teams. If widely rolled out, it could impact how SEOs interact with performance data.

Policy UpdateOct 8, 2026

US Government Excludes Microsoft from Visa Program

The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
