AI is changing how users search, but it is also changing how SEO is measured and optimized. For Vietnamese marketers, what matters is not only rankings on traditional Google, but also whether a brand gets “mentioned,” “cited,” or unintentionally introduces a competitor to users through AI.
The 8 latest SEO updates below paint a fairly clear picture: content needs to be structured better, web infrastructure must be more machine-readable, and brand strategy has to account for both AI search and local search.
-
Key points:
- AI Search can cite your content but then recommend a competitor right within the list you created.
- Google is said to be evaluating content structure factors such as Markdown in the context of AI SEO.
- The local marketing market is becoming more chaotic as businesses use multiple layers of AI tools but struggle to prove ROI.
- The web is developing an additional “machine-readable layer,” forcing SEO to understand infrastructure, not just content optimization.
When “best tools” content accidentally promotes competitors in AI Search
Search Engine Journal raises an important warning for SaaS businesses and B2B brands: “top tools” articles that once worked very well in traditional SEO may backfire in AI Search. According to the article, Google AI Overview can cite your list as a reference source, then recommend a competitor included in that same list instead of your product.

This shows an important shift in how AI understands and selects answers. Your content no longer just needs to be “seen”; it must also be persuasive enough that AI does not redirect users to another brand. The lesson here is that marketers need to revisit “comparison,” “ranking,” and “best of” articles with a focus on real advisory value, rather than simply trying to claim the number one spot through a familiar list structure.

5 lessons from a study running AI agents across every type of query
Another Search Engine Journal study summarizes 5 lessons from running AI agents across many different types of search queries. The focus of this research is not only how quickly AI answers, but how AI agents interpret query context, shift source priorities, and combine signals from multiple results.
What matters for SEO is that optimization strategy cannot rely on just one type of intent. For the same topic, AI agents may follow different information paths depending on context, which means content must be clearer about definitions, entities, semantic relationships, and how useful it is at each step of the search journey. For content SEO teams, this is a reminder that “writing for readers” now also has to mean “writing for reasoning systems.” Source: Search Engine Journal.
Local marketing is getting too complex because AI tool layers are stacking up
In multi-location marketing, Search Engine Journal highlights a very real problem: the more AI tools businesses add to manage listings, reviews, customer sentiment, or local presence optimization, the more chaotic the system becomes. The ideal picture is AI automatically fixing errors, suggesting optimizations, and managing responses. But in reality, many brands now have a patchwork infrastructure, making it nearly impossible to track overall performance.
The article cites an Uberall survey showing that only about 1/4 of local marketers can prove the impact of local marketing on sales. For local SEO, this is a strong warning: automation cannot replace a clean data structure, clear permissions, and a consistent measurement framework. Otherwise, AI only speeds up the mess.

Hydration and SEO: why “loading” content the right way matters more
Search Engine Land analyzes hydration in SEO as part of the process by which content and interfaces are fully “loaded” in the browser after a page renders. For modern websites, especially as JavaScript and dynamic display layers become more common, whether content appears at the right time for users and search bots is a key question.
The core point here is that SEO no longer stops at keywords or backlinks. How a page is built, how data is rendered, and how content becomes available to crawlers directly affects how well it can be understood and indexed. This is an area many marketers overlook because it sits at the intersection of SEO, web development, and user experience. Source: Search Engine Land.
62% of AI brand suggestions disappear after a follow-up question
New research from Clovion AI, reported by Search Engine Journal, shows something very notable: 62% of AI brand suggestions disappear after users ask a follow-up question. This reflects the instability of the “AI funnel” in the buyer decision journey.
The survey also found that three AI assistants such as Claude, ChatGPT, and Gemini can contradict one another on brand information in a significant share of cases. For SEO and content professionals, this result is a reminder that visibility in AI search does not mean consistency. To be trusted, a brand needs structured content, consistent information across touchpoints, and clearly described entities to reduce the risk of AI misinterpretation. Source: Search Engine Journal.
What is Google saying about Markdown in AI SEO?
Search Engine Journal continues to track discussion around Markdown and its role in AI SEO. While Markdown should not be treated as a “magic trick,” the overall trend is that Google and AI systems are prioritizing content that is logically organized, easy to layer, and easy to reason about.
From a practical perspective, Markdown helps content become more clearly structured: headings, lists, quotes, tables, or sections are expressed consistently. This can support machine understanding of content, especially as the web moves closer to new machine-readable standards. For content teams, this is a signal to standardize editing practices instead of focusing only on article length. Source: Search Engine Journal.
The July 7 forum recap shows the search ecosystem is expanding fast
Search Engine Roundtable’s Daily Search Forum Recap shows that the pace of updates across the search ecosystem is still accelerating. On the same day, Google Search Console was mentioned with verification and performance-tracking features for social channels, Merchant listings structured data documentation was updated with the Product.category attribute and Sale duration mechanism, and Google Ads, AdSense, and ChatGPT Ads also saw new changes.
For SEO, this is a very important context: search is no longer a single channel but is converging with social, e-commerce, advertising, and AI chat. Marketers need to monitor the entire ecosystem, because a change in Search Console, schema, or ads can affect how content is found, understood, and distributed. Source: Search Engine Roundtable.
The web is forming a “second layer” for machines
The Search Engine Journal article on the web’s “second layer” is perhaps the most comprehensive picture in this roundup. The author argues that beneath the traditional web, a parallel infrastructure is emerging, where standards such as Open Knowledge Format, Agentic Resource Discovery, MCP/WebMCP, LLMs.txt, and machine data-understanding models are all coexisting and evolving.
The key message here is that SEO needs to distinguish between technology layers instead of lumping everything under the label “AI SEO.” Not every new standard solves the same problem, and not every tool deserves the same priority. SEO, content, and dev teams need to sit down together to define which layer is data, which is discovery, which is entity description, and which is user experience. Source: Search Engine Journal.
What this means for the Vietnamese market
For Vietnamese businesses, the updates above point to two priorities that should be addressed immediately. First, review comparison articles, ranking lists, and buying guides: if an article only tries to “win” a position without creating real differentiation, AI can absolutely use that content to send users to a competitor.
Second, Vietnamese SEO needs to move closer to technical thinking: data structure, brand information consistency, machine readability, and performance measurement at each touchpoint. As AI Search grows quickly, the advantage will belong to brands with useful content, clean data, and a web infrastructure clear enough for both humans and machines to understand. That is the sustainable foundation for search growth in 2026 and beyond.
