Buyers are not choosing between them, they are using both for different parts of the same decision. Knowing which part goes where tells you where your store has to be legible.
- Assistants win open ended questions. Search wins known item lookups.
- The assistant usually happens first, which is when the shortlist forms.
- Being absent from the shortlist stage is the expensive failure.
Which questions go where?
The split is fairly consistent, and it maps onto how far along the decision the buyer is.
Why does the order matter?
Because the assistant question usually comes first, and it is where the shortlist is formed. By the time somebody types a specific product name into search, the choice has largely been made and you either are or are not on the list.
A store that is highly visible in search but invisible to assistants gets found by people who already decided, and never enters the consideration of people who had not.
Does this mean search matters less?
It means search matters differently. Known item lookups are still enormous and still convert best, so ranking still matters. What changes is that the discovery layer above it moved.
The work overlaps heavily, which is the good news. What overlaps and what does not sets out where the effort is shared.
Where should a store put its effort?
Both, in one pass, because the foundation is shared. Crawlable pages, complete product data and clear answers serve a search engine and an assistant at the same time.
The only place they diverge much is measurement, since one has positions and the other has mentions. Tracking the assistant side needs its own setup.
Common questions
Are people really shopping through ChatGPT?
For research and shortlisting, widely. For completing purchases, increasingly, though the mechanics still vary by platform and checkout.
Should I optimise differently for each?
Not at the foundation. Fix crawlability, product data and answer shaped copy once and both benefit. Per engine tuning is a refinement afterwards.
Which sends better traffic?
Assistant referrals tend to be fewer and further along the decision. Search sends more, spread across every stage. Judge each on what the visitors do, not on volume.
