Structured Data That AI Search Engines Actually Read
The Types That Rarely Earn Their Keep Elaborate breadcrumb hierarchies, speakable markup, deeply nested item lists and most of the specialised types outside their intended vertical produce little observable difference in how a brand is understood or recommended.
In most categories the pages that generate answers are review platforms, directories, forum threads, comparison articles and trade publications. Being absent or wrong on those explains far more absences than anything on a brand's own site, and correcting a listing costs an afternoon.
Treat markup as something with a maintenance cost rather than a one off implementation. Prices change, people leave, products are discontinued, and structured data quietly keeps asserting the old version long after the visible page has been updated. Adding a schema review to whatever process already updates your pages costs minutes and prevents the most damaging failure mode, which is confidently stating something that is no longer true.
Search traffic includes everybody at every stage, including a large volume of people gathering background information with no intention of buying anything. Assistant referrals skip most of that, because the informational portion was satisfied before the click.
One inversion is worth noticing in your own analytics. The pages that earn citations are frequently not the pages that earn traffic, and teams optimising purely for sessions will deprioritise exactly the specification and comparison content that this channel uses. Keeping a separate note of which pages appear in citation lists prevents a well performing asset being retired because its visit numbers looked unremarkable.
One additional check is worth building into your product page template. Every page should be able to answer, in text, what the product is, what it costs, what size or specification options exist, what it is compatible with and who it is not suitable for. Most templates cover the first two and leave the rest to imagery or to a downloadable document, which removes exactly the details that a purchase recommendation needs.
Being the Source Instead of the Casualty The summary cites sources, and being one of them is now a legitimate objective. The requirements resemble what earns citations anywhere else: a page that answers directly, contains specifics worth attributing, and is reachable and readable by a crawler.
The defensible version states the mechanism, cites the available evidence with its sample sizes, presents your own segmented data however thin, and is explicit that most of the channel's value is not measurable through referrals at all.
Preference is the wrong word, strictly. These systems do not have taste. They reach for sources that match the shape of the answer being written and that contain claims which can be lifted without distortion, and certain formats do that reliably.
The caveat is that most published question sections are marketing in disguise, containing questions no customer has ever asked, phrased to permit a favourable answer. Those get ignored, and they are easy to spot.
What to Do First Run five prompts describing a purchase your best customer would be making, llm seo from a signed out session, and see what gets named and cited. Then check whether your product data survives with scripts disabled, and whether your name and identifiers are consistent across every listing you can find.
Where Marketplaces Fit Marketplace listings are frequently cited, and they are a mixed blessing. They provide corroboration and structured data you did not have to build, and they put a description of your product in circulation that you only partly control.
If you want your own figure, the segment worth building is narrower than most people set up. Compare assistant referrals against branded organic search rather than against all organic, over at least a quarter, and exclude any campaign traffic. It will be a small sample and it will be about your audience, which makes it more useful for your decisions than a published study about somebody else's.
The version that fails is the vendor comparison where every row favours the publisher. It is transparent to readers and useless as an impartial source, which is why it appears in citation lists far less often than its authors expect.
The result is a content programme aimed at guesses. Sometimes it works by accident. Usually it produces pages nobody retrieves, and the diagnosis that would have directed the effort correctly costs a fraction of what the content did.
The same errors recur across companies of every size, and most of them are not technical. They are misjudgements about where the work lives, made early, and expensive to unwind because the budget has usually been spent by the time anyone notices.
A final error deserves separate mention because it undoes good work rather than merely wasting effort. Teams that get an early result frequently conclude they have found the mechanism and generalise from one change. A directory correction coincides with a mention appearing, and directory corrections become the strategy, when the actual cause was a rewritten page indexed the same week.
