Google’s December Core Update: What SEO, AI & Creators Need to Know in 2025

If you missed it, Google rolled out another core algorithm update, and yes—rankings are once again under pressure. As usual, Google didn’t reveal every detail, but the signals are clear: low-quality, thin, and AI-fluffed content is struggling, while genuinely useful content is holding stronger.

Let’s break down what’s happening, what it means for SEO and AI-driven content, and how creators and marketers should adapt moving forward.

Google December 2025 Core Update: What’s Really Going On?

On December 11, 2025, Google officially launched its December Core Update. The rollout is expected to take around three weeks, meaning rankings may fluctuate right through the holiday season and into January.

Core updates don’t target specific sites—they reassess how Google evaluates content quality overall. Some pages rise, others fall, and many businesses are left refreshing Search Console a little too often.

Sites Most at Risk After This Update

If your site checks any of the boxes below, rankings may be vulnerable:

• Thin pages that barely answer the search query
• Heavy use of auto-generated or templated AI content
• Affiliate or review sites with surface-level insights
• Competitive niches with repetitive, near-duplicate content
• Pages lacking authority, trust, or real expertise

In short: content written for algorithms instead of people is being tested.

What Google Still Rewards (Most of the Time)

No site is completely “safe,” but Google continues to favor pages that focus on users first:

• In-depth, helpful content that answers real questions
• Clear proof of expertise, experience, and trust (E-E-A-T)
• Fresh, updated content aligned with search intent
• Strong user experience and technical performance
• Natural backlinks from reputable, relevant websites

SEO still works—but shortcuts don’t.

Don’t Like Ranking Volatility? Become a Creator

Between SEO, AISEO, AEO, GEO, and every new acronym added this year, many marketers are exhausted. Ranking volatility is normal now, and Google isn’t pretending otherwise.

Interestingly, while warning about unstable rankings, Google quietly released AI-powered video editor templates inside Google Photos. These tools allow creators to:

• Add text overlays automatically
• Create vertical-friendly videos
• Auto-edit clips for social platforms

The message is subtle but clear: audiences are moving, and Google knows it.

Recent data shows many marketers now trust social platforms more than search engine marketing, not because they’re perfect—but because volatility is expected and transparent.

SEO isn’t dead, but creator-led visibility is rising fast.

Is Link Building Still Relevant in 2025?

Yes—but it’s smarter now.

Every few months, someone declares link building “dead.” In reality, spammy link building is dead, while relevant, contextual links still matter a lot.

Good backlinks today come from:

• Editorial mentions
• Industry publications
• Local and niche-relevant sites
• Genuine partnerships

Bad links still exist—and Google still notices them.

Founder-Led Marketing Is Quietly Winning

People trust people more than brands. Founder-led marketing continues to outperform generic brand messaging because it delivers:

• Authentic opinions
• Faster decision-making
• Human credibility
• Personal storytelling

In an AI-heavy internet, human presence stands out.

SEO Has “Died” Again… And Yet It’s Still Here

SEO has been declared dead more times than we can count. Each time, it evolves instead of disappearing.

The takeaway?
SEO doesn’t vanish—it adapts to user behavior, platforms, and technology.

From Reddit: Does Backlink Relevancy Really Matter?

A popular Reddit discussion asked a surprisingly honest question:

“Can I partner with local restaurants, promote them, and earn backlinks—even if they’re not in my niche?”

The consensus from experienced SEOs:

• Relevancy matters, but it’s not “same niche or nothing”
• Google evaluates context, placement, and intent
• Local relevance can absolutely support SEO
• A restaurant link works if it makes sense (e.g., a local partners page)

One warning stood out:
If your link-building logic starts with “but in real life…”, pause. That’s how messy backlink profiles happen.

Context beats clever tricks—every time.

A Look Back: Buying Bulk Backlinks (And Why It Failed)

Once upon a time, SEOs bought backlinks by the hundreds for a few dollars. Some saw short-term spikes. Many saw long-term penalties.

Bulk backlinks came from:

• Link farms
• Low-quality blogs
• Abandoned domains

Google caught on fast.

• The lesson still applies today:
• Build links where your audience already exists
• Prioritize real sites, real readers, real traffic

The algorithm can smell desperation.

Final Thoughts

SEO, AI, and content marketing are no longer separate lanes—they’re merging fast. The brands that win in 2025 will be the ones that:

• Prioritize real value over volume
• Combine SEO with creator-led visibility
• Build authority through trust, not tricks

Change is uncomfortable—but it’s also where opportunity live.
