The latest SEO Pulse from Search Engine Journal, written by Matt G. Southern, covers four developments. A core update is rolling out. Google's AI Mode has switched to a new default model. OpenAI's ChatGPT Business Hub now shares mention and click counts with businesses. Websites are also planning for less search traffic. Taken together, these signal that ranking volatility, AI-generated answers and new visibility metrics now need to be managed as one problem.
- A core update is rolling out (Search Engine Journal, SEO Pulse).

What does the latest core update mean for rankings?
In SEO, a core update is a broad change to how search results are ranked. It is not a penalty aimed at specific tactics. Search Engine Journal's summary confirms that a rollout is underway but does not describe its scope. Site owners should therefore avoid drawing early conclusions from day-to-day swings.
Experienced teams follow a simple discipline during a core update:
- Wait for the rollout to finish before comparing before-and-after performance in Google Search Console.
- Segment the data by page type, topic cluster and query intent. Sitewide averages hide where the movement actually happened.
- Compare against competitors who rank for the same queries. If their pages gained where yours lost, study what their content does differently.
- Resist rushed rewrites. Large edits during a rollout make it harder to tell what caused any recovery.
This core update also lands while AI answers sit on top of or beside organic results. A ranking position now carries less certain traffic value than it once did. That context matters for everything below.

Why does a new default model in Google AI Mode matter?
Search Engine Journal reports that AI Mode now runs on a new default model. The summary does not name the model or detail what changed, so any claims about specific behaviour would be speculation. The strategic point holds either way: when the model behind an AI search product changes, it can choose different sources to cite.
Classic ranking rests on years of documented signals. AI answer engines are less transparent. A model change can alter how queries are interpreted, how many sources are cited and which kinds of pages are preferred. Brands that saw steady citations in AI Mode should treat this as a moment to re-check, not assume.
How to monitor AI Mode visibility after a model change
- Keep a fixed list of priority prompts and queries, and test them regularly so you are comparing like with like.
- Record which domains are cited, not just whether your own brand appears.
- Note when answers change format, for example longer summaries or fewer links. Format changes affect click potential as much as citation does.
What does ChatGPT Business Hub show about mentions and clicks?
The most practical item in this SEO Pulse is OpenAI's ChatGPT Business Hub sharing mention and click counts. Until now, marketers measuring AI visibility have mostly relied on manual prompt testing or third-party tools that estimate presence. First-party mention and click data from the platform itself is a different kind of evidence.
Search Engine Journal's summary confirms only that these two numbers are reported. Even so, they map onto a familiar measurement pair from traditional search:
| Search metric | Closest AI assistant equivalent | What it tells marketers |
|---|---|---|
| Impressions (Google Search Console) | Mentions (ChatGPT Business Hub) | How often the brand appears in answers |
| Clicks (Google Search Console) | Clicks (ChatGPT Business Hub) | How often that appearance drives a visit |
| Click-through rate | Clicks divided by mentions | Whether being mentioned actually produces traffic |
The ratio between mentions and clicks is where the insights will come from. Many mentions with few clicks suggests ChatGPT is answering the user's question fully, so the brand gets awareness but little traffic. That is useful for brand marketing and weak for lead generation.
Teams working on this channel should read Whizsky's guide on how to get recommended by AI tools like ChatGPT and Claude. It is also worth keeping perspective. Whizsky has covered OpenAI's own comparison showing that Google search volume still far exceeds ChatGPT's.

Why are sites planning for less search traffic?
The final thread in Search Engine Journal's roundup is that sites are planning for less search traffic. That is the logical result of the other three items. Core updates shift rankings, AI Mode answers queries directly, and AI assistants become a discovery channel of their own. The old assumption that good rankings bring predictable traffic is weakening.
Planning for less search traffic does not mean giving up on SEO. It means changing what success looks like. Practical moves include:
- Diversifying acquisition through email lists, communities and direct relationships that do not depend on one algorithm.
- Valuing visibility as well as visits. A brand cited in AI answers may gain demand that later shows up as branded search or direct traffic.
- Prioritising pages AI cannot easily replace. Original data, tools, first-hand experience and transactional pages keep their click value when quick-answer content does not.
- Reforecasting budgets so leadership does not judge SEO only by organic sessions that are declining across the industry.
Whizsky's analysis of how ChatGPT referral traffic compares with Google is a useful reality check here. AI visibility is growing in importance, but it is not yet a like-for-like replacement for organic search traffic.
Key Takeaways
- Don't react to the core update mid-rollout. Measure once it settles, and segment the results by page type and intent.
- Re-check your AI Mode citations. A new default model can change which sources appear, even if your Google Search rankings did not move.
- Use ChatGPT Business Hub data. Treat mentions like impressions and clicks like clicks, and watch the ratio between them.
- Plan for less search traffic. Build channels you own, and report on visibility alongside sessions.
This week's news shows that SEO now spans traditional rankings, AI-generated answers and assistant platforms. Teams that track all three, and explain the trade-offs clearly to stakeholders, will be in the best position to adapt.
Frequently Asked Questions
What should site owners do during a core update?
Wait until the rollout is complete before judging performance, then compare before-and-after data in Google Search Console by page type and query intent. Avoid large content rewrites mid-rollout, because they make it hard to tell what caused any change.
What does ChatGPT Business Hub show businesses?
According to Search Engine Journal, ChatGPT Business Hub shares mention and click counts. Marketers can read mentions as roughly similar to impressions and clicks as visits, which makes the ratio between them a useful measure of whether AI visibility produces traffic.
Why does a new default model in Google AI Mode matter for SEO?
The model behind an AI search product shapes how queries are interpreted and which sources are cited. When the default model changes, brands should re-test their priority queries rather than assume their previous citations will continue.
Should businesses expect less traffic from search?
Search Engine Journal reports that sites are planning for less search traffic as AI answers and ranking changes reshape discovery. Businesses should diversify into owned channels and report brand visibility alongside organic sessions.
