Organizing the SEO team at Decathlon France in the face of Google deindexing in 2025
The effectiveness of an SEO strategy during such a disruptive event relies largely on team structuring and coordination. At Decathlon, a clear organization is emerging, where each country has its own SEO department, ensuring tailored local management while remaining connected to a global vision. This division allows for rapid adaptation of actions based on market specifics and effective information sharing. The approach favors decentralized decision-making, where those on the ground can evolve tactics without waiting for centralized instructions.
The technical team, for its part, plays a crucial role with a precise roadmap dedicated to crawl optimization, sitemap management, and compliance with Google’s new rules. SEO experts, skilled in both auditing and technical development, work together to quickly identify deindexed or at-risk pages, while proposing solutions to preserve or improve the site’s SEO. Teams

In a context where deindexing is disrupting the established order, data analysis is becoming the cornerstone of strategic action. At Decathlon, the implementation of a multi-country observatory, accessible to all SEO managers, allows them to leverage a large volume of information from Google Search Console, analytics, and other specialized tools. Comparing the impacts between the French, German, Italian, and Polish markets offers a global perspective: *What content is at risk of being abandoned?* *Which content is resisting the wave of deindexing?*
This level of detail requires going beyond a purely technical approach. It involves interpreting Google’s signals to detect pages that are virtually invisible or unused, while isolating those that remain essential for conversion. The ability to analyze in-depth, using a personalized dashboard, allows for informed decisions rather than panicky reactions. The key: quickly identify whether specific content needs to be optimized, rewritten, or deleted to minimize the overall impact on SEO.

The fight to maintain SEO despite the deindexing movement also involves technical aspects. At Decathlon, technical vigilance is based on several strict rules regarding the sitemap, crawling, and content. The first step is to ensure full compliance with Google recommendations by verifying that all URLs meet a 200 status, are not blocked by robots.txt, and do not contain a noindex tag.
The organization of sitemaps must meet specific structuring criteria, with separate files for each type of content to facilitate their monitoring and updating. The maximum size of a sitemap should not exceed 50,000 URLs or 50 MB, and using a sitemap index makes it easier to manage large amounts of content. Beyond compliance, the content must be carefully curated: only pages with high strategic value, enriched with unique content, should remain indexed. Regularly updating sitemaps, monitoring for errors, and deleting old pages then become essential routines. Caution remains the best weapon: no mass deletion without prior analysis, to avoid a boomerang effect on overall SEO.Technical Criteria

- When a movement of this magnitude shakes up SEO, the reflex must be one of caution. At Decathlon, a rational approach—one that prioritizes diagnosis, prioritization, and measurement—results in the ability to quickly take a step back. Responsiveness isn’t limited to a knee-jerk reaction; it relies on ongoing monitoring, using appropriate tools like Google Search Console or data analysis tools. It’s important not to panic, especially when most indicators remain stable or slightly up. The goal is to distinguish a one-off event from a real strategic problem. The priority is always to anticipate, adjust, and continue to nurture an SEO strategy focused on quality rather than quantity. In this regard, Decathlon’s recommended practice is to maintain active monitoring, activate automated alerts, and synchronize efforts with all teams involved in marketing, content marketing, and technical development.
