Core Update March 2026: online stores, forums, and language tools hit in France and Germany

The rollout of the Google Core Update of March 2026 completed on April 8. According to two analyses conducted by SISTRIX, in France and in Germany, the verdict is severe: Google is massively redistributing visibility in favor of official sources and established brands, to the detriment of online stores, forums and language tools. In France there are 14 losers for 1 winner. In Germany the ratio is 4 to 1. Comparative overview.

Key takeaways:

  • Google favors institutional sources and market leaders in both countries.
  • Language and educational tools are the most affected sector, likely linked to the rise of AI tools.
  • Online stores are losing massively, regardless of their size or sector.
  • The imbalance between losers and winners is much more pronounced in France (14 to 1) than in Germany (4 to 1).

One signal, two different magnitudes

On March 27, 2026, Google launched its March Core Update with a rollout that ended on April 8. The logic is the same on both sides of the Rhine: a source's authority takes precedence over the interchangeability of its content. But the scale of the damage is not the same.

In France, the analysis of 2,991 domains showing significant fluctuations made it possible to identify 239 losers and only 17 winners with a demonstrable update effect.

In Germany, out of 1,371 domains analyzed, there are 134 losers and 32 winners. The French market is therefore hit much harder in proportion, with a losers/winners ratio of 14 to 1, compared with 4 to 1 across the Rhine.

Online stores: the most affected sector in both countries

This is the clearest and most cross-cutting trend.

In France, 80 of the 239 losers are online stores, exactly one third. The losses are not concentrated in a single segment: furniture (alinea.com -37%, pierimport.fr -28%), food (elmut.fr -50%, graines-semences.com -28%), music (paul-beuscher.com -58%), automotive (europcar.fr -26%) or tech (backmarket.fr -25%).

In Germany, 39 of the 134 losers are e-merchants, making them also the largest group. The same observation: losses span all categories. Fashion (cecil.de -30%), electronics (media-dealer.de -37%, alternate.de, conrad.de), plants and gardening (123zimmerpflanzen.de -27%, samenhaus.de -26%), B2B supplies (otto-office.com, hygi.de). And contrary to what one might expect, the major chains are not spared: notebooksbilliger.de and expert.de each lose 11%.

The message is clear : having an online store is no longer enough. Without a strong brand reputation behind it, organic visibility is eroding.

Language and educational tools facing AI

This is arguably the most revealing trend of this update. In both countries, conjugation, translation, definition and learning tools decline simultaneously.

In France : toutelaconjugaison.com (-32%), littre.org (-30%), bab.la (-20%), glosbe.com (-25%), lingolia.com (-15%), kartable.fr (-14%), reverso.net (-12%), francaisfacile.com (-7%). The case of the Littré is particularly symbolic: this historic reference of the French language drops from a visibility index of 61 to 43. It's a brutal fall for a site that has been an authority for decades.

In Germany, the pattern is almost identical: verbformen.de (-30%), bab.la (-22%), korrekturen.de (-15%), studysmarter.de (-15%), linguee.de (-10%), openthesaurus.de (-9%), reverso.net (-7%). Seven tools hit simultaneously.

What makes this cluster particular is the context in which it sits. These sites offer features increasingly covered by AI applications : conjugations, translations, synonyms, grammar exercises. In Germany, chatgpt.com gains 32% visibility on Google at the same time. It's hard not to draw a link. But caution is required: is Google actively devaluing these sites, or are user search behaviours changing? Upcoming updates will provide answers.

Forums and user-generated content

User-generated content platforms are also under pressure, but Google makes notable distinctions.

In France, supertoinette.com, the cooking forum, loses 46% of its visibility. stackoverflow.com falls 45% in the French market. jecontacte.com (-31%) is also affected.

In Germany, gutefrage.net loses nearly a quarter of its visibility (from 62 to 47). The trajectory of this site is particularly telling: its visibility index peaked at 127 in spring 2025. It had already fallen to 54 in early 2026 before the Core Update, which pushed it down further to 47. X.com loses 25% and xing.com 14%.

But Google does not penalize all forums in the same way: Reddit actually gained visibility during the recent updates. It's therefore less the UGC format itself that's being punished than specific platforms, probably for reasons of perceived quality or authority.

Publishers and media: targeted losses

In France, several media outlets and publishers are affected: dvdclassik.com (-33%), hachette-vins.com (-46%), herodote.net (-26%), as well as nouvelobs.com and lesechos.fr.

In Germany, recipe portals are particularly targeted: kuechengoetter.de (-29%), schlemmer-atlas.de (-25%), eatsmarter.de (-18%), essen-und-trinken.de (-11%), lecker.de (-6%). But chefkoch.de, the leader of the German recipe market, remains stable. The signal aligns with the general logic of this update: the leader holds, secondary players retreat.

The winners: few, but revealing

On the winners' side, the list is short. 17 domains in France, 32 in Germany. But their profile is very instructive.

In France, four government sites are progressing simultaneously: pole-emploi.fr (+11%), hautsdefrance.fr (+7%), paris.fr (+3%), interieur.gouv.fr (+1%). societe.com, the reference for consulting French company data, gains 50% visibility (its index rises from 13 to 19). conforama.fr (+7%) and cuisineaz.com (+2%), both leaders in their segment, also make gains. pleinevie.fr, a general-interest magazine founded in 1981 with nearly 800,000 copies distributed, doubles its visibility.

In Germany, the strongest signal comes from an unexpected cluster: four official airports gain simultaneously. Stuttgart (+22%), Cologne-Bonn (+18%), Hamburg (+17%) and Munich (+8%). When four domains in the same niche improve at the same time and in parallel, it is not a coincidence. Google appears to have reorganized search results related to airports in favor of official sites, to the detriment of third-party comparison sites and aggregators. Other notable winners in Germany include ratiopharm.de (+12%), commerzbank.de (+11%), the government sites hessen.de, arbeitsagentur.de, wwf.de. And audible.de, with +172%, which is the biggest winner of this update in Germany, although its effect was not noticeable until April 3, a week after the rollout began.

What this update says about Google's strategy

In both countries, the direction Google has taken is the same: The authority of a source takes precedence over the mere usefulness of its content. Institutional sites, market leaders and long-established brands are rewarded. Interchangeable, generalist content or content covering features now provided by AI are penalized.

The difference in ratio between the two countries (14 to 1 in France, 4 to 1 in Germany) could be explained by structural differences differences in local markets and in the composition of the sites analyzed, rather than by a different intent from Google. But it deserves to be monitored during upcoming updates.
