A client called last month to say their organic sessions were down 19% year on year and their enquiries were flat. They wanted to know which number was wrong.
Neither. That gap is the story of search right now, and if you only watch sessions you will conclude your content has stopped working at exactly the moment it is doing its job.
Google answers more questions on the results page than it used to. AI Overviews, featured snippets, People Also Ask, the lot. Someone types a question about supplier selection, reads a synthesised answer, and never clicks. Your page was the source. You get no session for it.
In B2B this hits a specific part of the funnel hardest: the definitional and comparative reading people do early. What is X. X versus Y. How much does X cost. That is the top third of most B2B content libraries, and it is the third that is losing clicks fastest.
The part that still clicks through is the bottom: specific vendor questions, pricing detail, implementation questions, anything where the reader has decided they need the actual source. Which is why enquiry volume can hold steady while sessions fall.
Three things, in order of how much they hurt.
You lose the middle of the reading path. The old model assumed a buyer landed on a definitional post, then wandered into three more pages, then converted six weeks later. Take the first click away and you have lost the entry point to the rest of the library. Internal linking cannot help a session that never began.
Your attribution gets worse. The reading that shaped the shortlist now happens off your property, which means HubSpot never sees it. First touch shifts to whatever they typed into Google once they already knew your name. Organic looks less effective than it is, and somebody proposes cutting the content budget.
Your competitors can be quoted instead of you. When the answer is assembled rather than linked, being the source is the whole game. If a synthesised answer names three vendors and you are not one of them, the click you did not get is the least of it.
Stop reporting sessions as the headline. Report impressions and average position from Search Console alongside sessions. If impressions hold and clicks fall, you are being read without being visited, which is a different problem from being ignored.
Write pages that can be extracted from. A clear question as a heading, a direct answer in the first two sentences underneath it, then the detail. That is simply how you write for a reader in a hurry, and the machines happen to parse it the same way.
Put the specifics behind the click. If the general answer can be lifted, make the reason to visit something that cannot: your numbers, your method, your worked example, your price. Generic content loses nothing by being summarised because there was nothing in it to lose.
Fix your schema, without expecting miracles. Article, FAQPage and Organization markup help a machine understand what it is reading. They do not buy you a place in an answer. Treat schema as hygiene.
Watch branded search. The most useful leading indicator we have found is branded search volume. If people are reading about you without clicking, some of them will later type your name. Branded search going up while non-branded clicks go down is a healthy pattern.
Two changes, both boring, both worth doing this quarter.
Build a dashboard that puts Search Console impressions next to HubSpot sessions and sourced pipeline for the same period. Most teams have these three numbers in three different places, which is how the argument starts.
Then add a "how did you hear about us" field to your main form, make it required, and read it every month. It is unfashionable and self-reported and it will tell you more about the dark part of your funnel than any attribution model you can buy.
If the reading happens somewhere you cannot measure, then what other people publish about you carries more weight than it did. That is the PR argument, and it has got stronger this year. Our colleagues on that side of Resonance spend their time on exactly this problem. See what that involves.
The short version: you can no longer separate the content you own from the coverage you earn, because a machine reading about your category will happily blend both into one answer.
