A new report from iPullRank looks at how Google’s Personal Intelligence feature influences whether products appear in AI Mode.
The SEO Center analyzed 1,922 responses to the AI Mode and found a 46 percent increase when it comes to products that are listed with an account linked to Personal Intelligence.
What they found
In the accounts linked to Personal Intelligence, the brands they tested appear more often, with mentions rising from 23.9% to 66.8%.
Those brands also moved into higher positions, with their top three placements increasing from 4.5% to 24.9%.
Gmail has had a strong influence on which brands are cited. Products added via email appeared in 53.6% of relevant responses, compared to 10.5% of products added with images.
The results of consumer product categories such as coffee machines, hoodies, and running shoes are easier to influence than heavy categories, such as banks and SEO agencies.
Personalization Hasn’t Replaced Web Sources
Even though a person’s context seems to influence which brands appear, AI Mode still puts out a lot of recommendations from web sources.
Other product sites make up about 49% of sources. Product sites posted by accounts linked to Personal Intelligence are also frequently cited, along with their Google Shopping listings. What was completely unsaid was the nature of the extraordinary results.
How the Test Works
The team worked with three Google accounts. One was a blank control account without Personal Intelligence. A second blank account was connected to Personal Intelligence and received product-related signals via Gmail and Google Photos. The third was the personal account of author Garrett Sussman, which had a history of Google years.
The test covers eight categories, including coffee machines, running shoes, banks, and streaming services. Each section was tested on all Gmail messages and Google Photos, with six types of information per section.
Not Showing Analysis
The iPullRank report does not reflect Google’s internal ranking of accounts linked to Personal Intelligence.
The team did not have access to the retrieval processes, model weights, or personal intelligence decision layer. The audit also used three accounts within 17 days, limiting the scope of the findings.
Email was the strongest signal tested, but the report doesn’t prove that Gmail is a universal mode AI feature. Check for disabled login status automatically.
Why This Matters
The iPullRank analysis is one of the first published attempts to measure how Google’s Personal Intelligence feature can affect product recommendations. The findings come from small, controlled testing and apply to selected accounts only.
Two important takeaways are that email content has proven to have a stronger effect than images, and that personal content has not replaced web support. Personal compatibility signals seem to work as additional features, rather than overriding web results.
Looking Forward
iPullRank says it plans to test signal decay, variations in email behavior such as opening versus unopening messages, and multiple product categories.
Quick sentences are another thing to look at, as different question formats produced different levels of product visibility in this analysis.
