The first week of July 2026 shows that SEO is still changing very quickly across three layers: technical, measurement data, and AI-influenced search behavior. For Vietnamese marketers, the news below is not just a platform update, but something that directly affects how websites are optimized, how performance is tracked, and how brand presence is managed in search.
-
Key points:
- Google and related tools are continuing to adjust how content is evaluated, especially with llms.txt, AI Overviews, and Search Console.
- Data errors, local review issues, and changes in indexing reports can distort how marketers read SEO performance if they are not closely monitored.
- AI Search does not replace SEO; instead, it still depends on content, structure, and traditional optimization signals.
- Signals from the SEO community show that traffic, clicks, and visibility are diverging sharply by query type.
Lighthouse flags llms.txt if Markdown links are not used
Search Engine Journal says the new Lighthouse Agentic Browsing audit in Chrome is reading the llms.txt file as a markdown document. As a result, if this file does not use Markdown link syntax, the test will fail even though all links are correct and still work normally.
What matters here is not whether the file is accessible, but how the evaluation tool “understands” the content structure. In other words, a small formatting detail can determine the audit result, even if the page or file itself has no real error. SEJ says adding just a few characters per link is enough to pass the test.
For technical SEO, this is a reminder that standards for the “agentic web” are still taking shape. What machines can read, what they can score, and how people write documentation may not yet fully align. Source: Search Engine Journal.
Google is investigating missing reviews on local business profiles
Search Engine Land reports that Google is looking into complaints about customer reviews being lost or disappearing across many local business profiles. At the same time, some users say Google has also paused reviews on local listings while the issue is being handled.
For businesses doing local SEO, reviews are not only social proof but also a layer of signals that supports trust and conversion. When reviews disappear, the impact is not limited to the average star rating; it also affects the ability to persuade new customers, especially in highly competitive service industries.
In this situation, marketers should monitor business profiles regularly, save screenshots of important reviews, and prepare a response process if display issues persist. Source: Search Engine Land.
The Indexing report in Google Search Console has been fixed
Also on July 3, Search Engine Land said Google fixed the indexing report in Search Console after a prolonged error period. Search Engine Roundtable described it as an issue that lasted about three weeks before being updated and fixed.
For SEO teams, this is a very important detail because Search Console is often the first data source used to check how pages are indexed, what errors they are facing, and whether visibility trends have changed. When the report is broken, SEO practitioners may misread technical performance and make rushed or unnecessary decisions.
This also serves as a reminder that data from search platforms is not always perfectly stable. Therefore, Search Console should be cross-checked with server logs, analytics, and field testing before concluding that a website has a major issue. Source: Search Engine Land; Search Engine Roundtable.
AI Overviews may not just be taking low-quality clicks
In Search Engine Journal’s SEO Pulse, a randomized experimental study on Google’s AI Overviews showed that organic click traffic dropped significantly when AI Overviews appeared. However, the data does not support the hypothesis that only “low-value” clicks disappear: bounce rate, return to search, and time on site did not show significant differences between groups with and without AI summaries.
This has major implications for content creators. If AI Overviews are reducing clicks more broadly than the argument that they only remove low-value clicks suggests, SEO strategy will need to focus more on being cited, being recognized as a brand, and maintaining a role in queries with clear intent.
SEJ also said the organic click drop was measured at 39.8%, with a stronger impact on informational queries, while navigational and transactional queries did not show significant changes in the small sample. Source: Search Engine Journal.
AI Search cannot be separated from traditional SEO
Another analysis on Search Engine Journal emphasizes that AI Search cannot operate effectively without an SEO foundation. Although AI answer tools may feel “very different” from traditional search, they still need well-crawled data, clearly structured content, and strong enough authority signals to filter information.
The core message is clear: AI Search does not eliminate SEO, but instead makes SEO a more important infrastructure layer. Brands that invest properly in content structure, entity data, authenticity, and retrievability will have an advantage in both classic search and AI experiences.
For marketers, this is the time to rethink how content is organized by topic, entity, and user need rather than simply counting keywords or focusing on a few individual landing pages. Source: Search Engine Journal.
The SEO community keeps discussing clicks, agents, and Bing’s changes
Search Engine Roundtable summarized a busy week in the search community: from debates about clicks lost in AI Overviews, to how AI agents handle pricing pages, to news that a long-time Bing executive is preparing to retire. It is the kind of “thermometer” that shows the search industry is changing both technologically and in terms of people and interaction models.
What stands out is that these discussions are no longer centered on Google alone. For SEO professionals, following Bing, AI agents, and how new systems read content will become increasingly necessary, especially as multi-channel search strategies become more common.
For performance marketers, this is a sign to expand both measurement and monitoring scope: not only looking at organic traffic from Google, but also tracking shifts on other search platforms and at AI-generated touchpoints. Source: Search Engine Journal; Search Engine Roundtable.
Google has fixed and updated the Page Indexing report
Search Engine Roundtable also confirmed that Google’s Page Indexing report has been fixed and updated. This continues the story of data errors in Search Console, showing that Google’s reporting systems can sometimes be briefly inaccurate while still significantly affecting day-to-day SEO analysis.
For businesses, this means internal reports should be read in a broader context. An unusual fluctuation in a report does not necessarily mean a site technical issue; it may simply be a display error or unsynchronized data on the platform’s side.
The right mindset now is to cross-check and avoid making optimization decisions based on a single data point. Source: Search Engine Roundtable.
Video SEO roundup: spam update, fraudulent DMCA, and ad changes
In the July 3 video recap, Search Engine Roundtable reviewed a series of notable developments: Google completed the June 2026 spam update, fraudulent DMCA takedown requests are causing problems for Google Search, AI Mode is improving link visibility for recipes, and AI Overviews are beginning to show an additional top stories carousel.
More importantly for marketers, there are changes in ad flows and data: Google is pushing searchers to publisher-hosted AMP instead of Google-hosted cache versions, while Search Console is recording first-data issues in AI performance reports, especially for Discover. These are signs that the search ecosystem is being adjusted on multiple fronts at once.
For SEO, the lesson is not just about one spam update. What needs to be tracked is how Google distributes traffic, how content is cited, and how performance data is recorded in each report. Source: Search Engine Roundtable.
A perspective for the Vietnamese market
From Vietnam’s perspective, this set of news shows that SEO is entering a more “multi-layered” phase than before: site technical health must be clean, data must be cross-checked, and content must be strong enough to be trusted by both users and AI systems. For small and medium-sized businesses, the practical priorities should be: review website structure, monitor Search Console against multiple reference sources, manage local reviews closely, and invest in topic-based content rather than chasing individual keywords.
As AI Search and AI Overviews have a clearer impact, the goal is not only to appear on the results page, but also to become a trusted source that new systems can cite. Vietnamese businesses that adapt early to the new way of searching will gain a clear advantage in visibility, credibility, and conversion.
