The big headline: Google’s December 2025 Core Update is finished 
Google’s December 2025 Core Update officially completed on Dec 29, 2025 after roughly 18 days of rollout (it began Dec 11). Search Engine Land+2Search Engine Roundtable
What marketers should do now (today + this week):
- Don’t knee-jerk rewrite everything. Now that the rollout is done, you can finally trust trendlines more than day-to-day noise. Start pulling pre-update vs post-update comparisons (e.g., Nov 15–Dec 10 vs Dec 29–today) at the page + query level in GSC. Search Engine Land
- Segment winners/losers by intent, not templates. Core updates tend to reshuffle based on satisfaction signals across the SERP—so categorize impacted pages by search intent (how-to, list, product, local, brand), then look for patterns.
- Communicate “seasonality vs update” clearly. Reddit chatter right now is full of “impressions down, rankings stable”—a classic mix of holiday demand dips + post-update settling. Your stakeholders need that nuance. Reddit
Search Engine Land also published a quick 2025 algorithm recap (3 core updates + 1 spam update), useful for retro reporting and post-mortems. Search Engine Land
AI in the SERP: publishers are feeling the squeeze (again)
1) “AI Frankenstein recipes” is going mainstream
Recipe creators are calling out cases where Google’s AI responses appear to credit a publisher’s brand while altering the recipe—risking both traffic loss and brand trust damage. This story is picking up broader media attention, and it’s a reminder: AI answers aren’t just a visibility issue; they’re a reputation issue. Search Engine Roundtable
Action for content brands:
- Add clear attribution hooks (author boxes, “tested by” language, schema where appropriate).
- Strengthen brand queries: You want “Brand + recipe/topic” searches to land on your verified experience pages.
2) Web Search traffic to news publishers is shrinking
Data cited from NewzDash suggests Google Web Search’s share of traffic to news publishers has dropped dramatically over two years, while Discover has become a dominant (and volatile) source. Search Engine Roundtable
Action for publishers/brands with content arms:
- Treat Discover like its own channel: tighter visual standards, fresher angles, and strong E-E-A-T signals.
- Diversify with email, direct, and social so a Discover swing doesn’t blow up the month.
Commerce shift: ChatGPT’s shopping push is a wake-up call for budgets
Search Engine Journal’s take on ChatGPT-native shopping frames a big strategic shift: discovery and purchase could compress into fewer steps, with conversational interfaces acting as the “front door.” Search Engine Journal
What to do in practical terms:
- Double down on product data hygiene (feeds, availability, shipping/returns clarity, structured data).
- Invest in brand demand creation, not just demand capture—because in AI-driven shopping, being the brand people ask for matters more than winning a single keyword auction. Search Engine Journal
SERP + platform tweaks you can act on fast
Bing: “People Also Ask” expansion test
Bing is testing a People Also Ask experience that loads more questions as users interact, plus richer source cards. If this sticks, it increases the value of FAQ-shaped content that answers follow-up questions cleanly. Search Engine Roundtable
Google: merchant panels add a scrollable “policies” carousel
Google is showing a carousel in merchant/retailer panels highlighting delivery, returns, and payment options—more reason to make those policies easy to crawl and consistent across your site. Search Engine Roundtable
Google Maps hotels: “Visit website” gets buried
A reported Maps test removes the “visit website” button from the first view in hotel results, nudging users deeper into Google’s own flows first. Hotels (and local brands) should watch for drops in direct referrals and adjust attribution expectations. Search Engine Roundtable
Microsoft Advertising: “All accounts” tab = faster ops for agencies
Microsoft Ads added an “All accounts” view for multi-account advertisers—small UI change, real workflow win for audits and recommendations triage. Search Engine Roundtable
Quick checklist for today (15 minutes)
- Pull a Dec 29–Dec 30 performance snapshot vs the prior week for top pages/queries. Search Engine Land
- Flag pages hit during the core update and sort by intent cluster.
- For ecommerce: review shipping/returns/payment visibility (site + feeds). Search Engine Roundtable
- If you rely on local/hotel discovery: monitor Maps referrals separately this week. Search Engine Roundtable
