Google is testing AI-generated summary descriptions inside AI Overview citation cards, Search Engine Roundtable reported in November 2026, based on a spot by SEO analyst Brodie Clark. The cards sometimes show a short AI-written description of the page rather than text pulled directly from the page. Clark noted the text does not appear exactly like that on the page: it is summarised based on what Google thinks is most relevant to the query. That small change has a large implication, because the words shown next to your link may no longer be your words.
A citation card has traditionally been a window onto the source: a title, a URL, and a snippet taken from the page itself, so the user sees what the source actually says before clicking. The test replaces that snippet with a summary written by the AI, tailored to the query. The card still points to your page, but the description of what your page contains is now Google's paraphrase, shaped by what it judges most relevant to the person searching.
That is a meaningful shift in control. A snippet drawn from your page is predictable: you wrote it, you can change it, and you can see it. A summary generated per query is none of those things. The same page could be described differently for different queries, and the description could emphasise an angle you would not have chosen, or soften a distinction you considered essential.
There is a genuine upside. A summary tuned to the query can be more useful than a fixed snippet, because it answers the user's actual question instead of showing whatever text happened to sit near the top of the page. If the summary is accurate, it may send better-qualified clicks: users who click understand what they will get, and users who do not need your page will skip it without costing you a bounce.
The downside is accuracy and emphasis. A summary is an interpretation, and interpretations can flatten nuance, drop caveats, or merge separate claims into one confident statement. A page that carefully distinguishes between two cases could be summarised as if it made a single blanket claim. And because the summary is generated, the publisher cannot edit it directly; the only lever is changing the underlying page and hoping the next summary reflects the change.
If AI-written card summaries roll out widely, the most important paragraph on your page may not be the one you wrote for readers, but the set of facts the AI can most easily summarise. Pages that state their key points plainly, early, and unambiguously will produce better summaries than pages that bury the point in a long build-up or express it only through implication. Clarity becomes a ranking factor in a new sense: not just for the reader, but for the machine describing your page to the reader.
It also raises the stakes on factual precision. A page with a loose claim or an ambiguous sentence gives the summariser room to go wrong, and the wrong summary then travels with your brand attached to it. Tight, checkable writing, with the important distinctions stated explicitly, is the best defence against being mis-summarised. In effect, you are now writing for two audiences at once: the human reader and the AI that introduces your page to them.
The broader question is who controls the description of a publisher's work in search. Snippets kept that control mostly with the publisher, since the text came from the page. AI summaries move it to the platform, which decides what your page is about for each query. That follows the same pattern as this week's other AI search news: platforms gaining more say over how content is presented, while publishers keep producing the content itself.
For now this is a test, and tests do not always ship. But the direction is consistent with everything Google has done with AI Overviews this year, and publishers should assume some version of it arrives. The practical response is to make pages easy to summarise correctly: lead with the answer, state distinctions plainly, and keep the facts clean. You may not control the summary, but you can control the raw material it is made from.
