Why this matters
If you run an agency or manage client SEO, "why did our traffic drop" is one of those questions that shows up in your inbox the moment a client glances at Google Analytics. A Search Engine Journal piece is clearly aimed at that exact conversation, framing it as a common issue for agencies right now and pointing toward AI visibility metrics as something to report alongside standard traffic numbers.
That framing alone is useful. It tells you the industry conversation has shifted from "is traffic down" to "what else should we be measuring and telling clients." Whether the shift is driven by algorithm changes, seasonality, AI-generated answers eating into clicks, or something else entirely isn't detailed in what's publicly available from the piece right now.
What we actually know
Here's the honest state of things: the publicly visible portion of this article is a short teaser. It confirms the topic (organic traffic drops, what to tell clients, and AI visibility metrics as an alternative or complementary reporting layer) but doesn't yet spell out the specific reasons behind the traffic dips, which metrics to use, or how to frame the client conversation.
That's worth flagging rather than glossing over, because the temptation in this space is to fill in the blanks with what sounds plausible: AI Overviews, zero-click search, generative answers replacing organic clicks. Those are all real, widely discussed dynamics in search right now, but attributing specific claims about them to this particular article before the full piece is confirmed would be getting ahead of the source.
What to do in the meantime
If a client is already asking why their numbers moved, the safe move is to pull your own analytics, check for known ranking or indexing issues specific to that site, and look at whether category-wide search behavior (not just your client) has shifted. Treat "AI visibility metrics" as a concept worth tracking, since it's clearly entering the mainstream reporting conversation, but confirm the specific metrics and definitions before you build a client deck around them.
We'll follow up once more of the underlying detail from Search Engine Journal is available.
