AI search and Google ranking fluctuations are pushing SEO into a more unpredictable phase, where measuring performance is no longer as simple as checking keyword rankings. For Vietnamese marketers, both signals matter: one is how the brand appears in AI answers, while the other is the stability of traffic from traditional search.
- Key points:
- Current “AI search visibility” measurement tools can show how often a brand is mentioned, but that is not necessarily the right measure of business performance.
- Measurement needs to distinguish between “being mentioned/cited by AI” and “the real impact on traffic, conversions, and revenue.”
- Google was reported to show signs of ranking volatility over the weekend around 18/7, although there has been no official update confirmation.
- For the Vietnamese market, SEO should shift from obsessing over rankings to a broader view: visibility, quality traffic, brand demand, and conversions.
Measuring visibility in AI search: don’t confuse “being mentioned” with “being effective”
An article on Search Engine Journal shows a reality many SEO and marketing teams are facing: AI search visibility tracking tools often count how many times an AI model mentions your brand or cites your source when users ask a question. The number is easy to see, easy to report, and quite similar to the habit of tracking traditional SEO rankings, so it is quickly being treated as a new KPI.
However, the article’s view is that caution is needed: appearing in an AI answer does not mean users will trust it, click it, or convert. In other words, “visibility” in an AI context can be a signal worth tracking, but it is not enough to conclude business effectiveness. What marketers need is to separate surface-level metrics from those that create real value.
According to the approach outlined in the source, the issue is not whether AI search should be measured, but what should be measured correctly. If you rely only on prompt tracking, you can easily get caught up in a new kind of vanity metric: it looks like progress, but it does not fully reflect user behavior, query quality, or the final impact on the business.
One notable point is that the article emphasizes the difference between indicators that “seem important” and those that are truly tied to business goals. For SEO teams, this requires combining data from multiple sources: branded queries, organic traffic, conversion rates, presence in AI answers, and real customer feedback.

Google continues to show signs of weekend ranking volatility
While marketing teams are learning how to measure AI search, Search Engine Roundtable reported signs that Google may have gone through another unconfirmed ranking fluctuation over the weekend of 18/7. The author said third-party tracking tools began recording broad movement, while the SEO community also discussed these changes more actively.
The important point here is the “unconfirmed” nature of it. That means there has been no official announcement from Google yet, but signals from tracking data and industry discussion suggest many websites may already have felt the shift. This context is very familiar to SEO professionals: short-term swings often appear before the market understands the nature of the change, or sometimes they are simply a ripple effect from earlier adjustments.
The post also revisits the volatility on 7/11, while noting that some believe what happened then may be “reversing” this time. Still, because there is no official confirmation, the safest approach is to monitor your own website data rather than rushing to conclusions based on the community’s general sentiment.
For marketers, the practical message is: when Google shakes up, don’t just look at a few core keywords. Check landing page segments, query types, geography, device, and conversions to understand where the volatility is having an impact. Source: Search Engine Roundtable.
A perspective for the Vietnamese market
Together, these two stories show that SEO is shifting from a game of “measuring position” to a game of “measuring influence.” In Vietnam, many businesses still report using only a few top 3 or top 10 keywords, but in a context where AI search is growing and Google may fluctuate continuously, that view can easily miss the real impact on revenue.
For Vietnamese brands, the priority should be to build a more balanced set of metrics: visibility in search results and AI answers, quality organic traffic, branded queries, organic conversion rates, and the ability to stay stable after updates or algorithm volatility. At the same time, content needs to be organized in a useful, expert-driven way with clear references to increase the chances of being selected by AI and search engines.
In short, SEO in Vietnam at this stage is not just about “ranking up,” but about building a durable presence across both Google and AI-based search experiences. Those who measure correctly will make better decisions.
