### Your GEO Strategy Might Be Destroying Your SEO

Source: [Lily Ray](https://lilyraynyc.substack.com/p/your-geo-strategy-might-be-destroying)

Lily Ray, SEO Consultant, breaks down how popular GEO hacks are actually tanking the organic rankings that AI search depends on. Since LLMs use search indexes to find sources (RAG), losing your rankings means disappearing from AI answers too. She flags five major risks: AI content spam, fake last updated dates, self-serving listicles, prompt injection buttons, and mass-produced comparison pages. **My take:** Don’t trade your long-term organic foundation for a 3-month AI hype spike. Most traffic is still search-driven, and LLMs need those rankings to find you in the first place.

### Google Releases March 2026 Spam Update

Source: [Search Engine Land](https://searchengineland.com/google-releases-march-2026-spam-update-472411) (https://searchengineland.com/)

Google just rolled out the first spam update of the year. Surprisingly, it finished in less than 24 hours. While Google calls it a standard update, these usually target policy violations like scaled AI content and link abuse. I’m currently monitoring the data to see what’s actually moving.

### Google Rolls Out March 2026 Core Update

Source: [Search Engine Journal](https://www.searchenginejournal.com/google-begins-rolling-out-march-2026-core-update/570657/) (https://www.searchenginejournal.com/)

Google launched its March 2026 core update on March 27, a broad overhaul expected to take about two weeks to complete. Coming right after the recent spam update, it is still too early to gauge the total impact on search results. However, [Lily Ray has already reported on X](https://x.com/lilyraynyc/status/2039882839898964315) that several sites are seeing significant drops in their rankings.

### Googlebot's 2MB Fetch Limit for HTML

Source: [Google Search Central](https://developers.google.com/search/blog/2026/03/crawler-blog-post) (https://developers.google.com/search)

Gary Illyes, Analyst at Google, explains how Googlebot stops fetching any HTML file once it hits a 2MB limit, ignoring all subsequent bytes. It makes sense to me; crawling the web requires significant resources and energy, and this provides a clear incentive for developers to optimize their code.

**Why it matters:** As an SEO specialist, indexation is a massive concern. We should verify if the pages we manage exceed 2MB and find ways to trim them if they do. To be honest, 2MB is a very high threshold for HTML. I would be surprised to find many pages above this limit but you never know, so it’s worth checking just in case. In the [tools section](/en/news/seo-geo-ai-news-march-23-to-april-5-2026.md#tools-news), I’ve included a website to quickly check if a page is above 2MB.

### Google adds digitalSourceType property to Forum and Q&A markup

Source: [Google Search Central](https://developers.google.com/search/updates#added-new-supported-properties-for-discussion-forum-and-qa-page-markup) (https://developers.google.com/search)

Google updated its structured data guidelines for Q&A and Discussion Forums to include the digitalSourceType property. This allows sites to explicitly label content as human, AI-generated, or a hybrid of both to provide more clarity to Google’s ingestion systems.

**Why it matters:** I've seen many new features like summary review boxes or automated FAQs. According to Google, it is now good practice to mention what is AI-generated. Personally, I don’t see the immediate value in adding it and won't be doing it yet, but it is worth noting.

### OpenAI Shifts its Agentic Commerce Strategy

Source: [OpenAI](https://openai.com/index/powering-product-discovery-in-chatgpt/)

OpenAI is scaling down its Instant Checkout model in favor of merchant-owned conversion paths. By expanding the Agentic Commerce Protocol (ACP), ChatGPT now facilitates visual product discovery and side-by-side comparisons by integrating direct merchant data feeds.

**Why it matters:** 1. This pivot is a reminder that our own websites remain our most important assets in 2026. 2. Treating OpenAI like Google by providing a merchant feed is a direct shortcut to increasing visibility within ChatGPT.

### Walmart Pivots from ChatGPT Instant Checkout

Source: [Search Engine Land](https://searchengineland.com/walmart-chatgpt-checkout-converted-worse-472071) (https://searchengineland.com/)

Walmart’s pilot of OpenAI’s Instant Checkout resulted in conversion rates three times lower than traditional website click-throughs. Daniel Danker, Walmart’s EVP of Product and Design, described the experience as unsatisfying, leading the retailer to pivot toward its own integrated 'Sparky' chatbot model.

### The End of the Listicle GEO Strategy?

Chris Long, Co-founder at Nectiv, describes how GPT 5.4 has refined its query fan-out process by searching significantly more sources and utilizing site: operators to verify brand features directly. This bypasses third-party listicles in favor of primary brand data and trusted aggregators like G2 or industry award winners.

**Why it matters:** This shift is ChatGPT’s first significant attempt to reduce the impact of manipulative tactics. It directly impacts GEO, as influencing LLMs through middleman comparison sites is becoming less effective than maintaining strong authority signals and trust data on your own domain.

### Identifying User-Triggered AI Actions with Google-Agent

Source: [Google Crawling Infrastructure Documentation](https://developers.google.com/crawling/docs/crawlers-fetchers/google-user-triggered-fetchers#google-agent) (https://developers.google.com/crawling)

Google has added a new user-triggered fetcher, Google-Agent, to its documentation to identify AI agents performing specific actions like navigating sites or filling out forms on behalf of users. I’m looking forward to seeing this in our agentic traffic dashboards at [LLM Optimizer](https://experienceleague.adobe.com/en/docs/llm-optimizer/using/dashboards/agentic-traffic) to better understand what these agents are looking for and to make sure they are not blocked along their journey.

### The Risks of Cloaking for AI Agents

Source: [QueryBurst](https://queryburst.com/blog/cloudflare-markdown-for-agents/) (https://queryburst.com/)

David McSweeney describes how [Cloudflare’s Markdown for Agents](https://blog.cloudflare.com/markdown-for-agents/) makes web cloaking trivial by allowing sites to serve deceptive, poisoned content to agents while humans see a clean version. My take is that AI crawlers will eventually get as smart as Google and will penalize this practice once they recognize the disparity between these dual representations of reality. However, since many LLM crawlers still cannot execute JavaScript, this feature remains useful for websites that rely heavily on Client-Side Rendering.

### LLM Extraction Pipelines and HTML Parsing

Source: [QueryBurst](https://queryburst.com/blog/html-to-markdown/) (https://queryburst.com/)

In another great blog post, David McSweeney tested how LLM agents utilize extraction pipelines to parse data rather than reading raw HTML directly. He argues that cloaking pages for LLM crawlers is largely ineffective because these models already receive cleaned context through standard parsing layers.

**Why it matters:** 1. I have a better understanding of why serving markdown to AI crawlers doesn't necessarily improve performance. 2. This insight has led me to start pre-parsing HTML in my own tools to reduce token consumption and improve model performance.

### Writesonic study on how LLMs crawl and extract content

Source: [Writesonic](https://writesonic.com/blog/ai-crawler-study-what-llms-see-on-your-website)

Writesonic conducted a test where they built a page with 62 hidden codes to see what LLMs would report. In short, ChatGPT, Claude, and Gemini don't execute JavaScript while JSON-LD, meta descriptions, and OG tags are stripped out in the extraction pipeline.

**Why it matters:** 1. Structured Data (SD) may not be directly ingested by LLMs, but I still believe it creates an indirect visibility loop. LLMs use query fan-out and RAG to ground answers in web searches; because search engines rely on SD to categorize and rank content, optimized markup increases the odds of the site being a selected citation. I will be conducting my own robust test in the coming weeks to validate this correlation. 2. If your website relies on CSR and you don't want to serve a blank page to major LLMs, pre-rendered HTML is non-negotiable.

## Adobe


### Marketing to Agentic Audiences

Source: [Adobe for Business Blog](https://business.adobe.com/blog/adoption-to-orchestration-marketing-to-humans-and-agents) (https://business.adobe.com/blog/)

Rachel Thornton, Adobe’s enterprise CMO, describes how AI agents as a new audience require structured brand data for agentic intent. As an SEO/GEO specialist, I fully agree. It mirrors the work we do at [LLM Optimizer](https://business.adobe.com/products/llm-optimizer.html): helping companies transition toward this new reality.

### EmDash: the new CMS from Cloudflare

Source: [Cloudflare](https://blog.cloudflare.com/emdash-wordpress/) (https://blog.cloudflare.com/)

Cloudflare has launched EmDash, a new CMS built on the Astro framework and positioned as the spiritual successor to WordPress. Its standout feature is a seamless migration path that allows you to move an entire site instantly via WXR files or a dedicated exporter. Having built [my own blog using Astro](/en/blog/seo-geo-technical-stack.md), I can vouch for the incredible performance and personalization it offers; seeing that same foundation at the core of EmDash makes it a serious contender in the Cloudflare ecosystem.

Dan Petrovic has released a new free GEO tool called Reverse Prompting, designed to identify potential prompts for a specific page or from an LLM output. This is a great resource when you want to track LLM visibility but are unsure where to start. At [LLM Optimizer we also provide prompts](https://experienceleague.adobe.com/en/docs/llm-optimizer/using/essentials/best-practices-topics-prompts) to our users based on several methods and it is always interesting to see a different approach to achieving this goal.
