Anyone Else Doubt Information Gain Really Affects SEO Rankings?

Anyone else notice how quickly SEO discussions turn “information gain” and “non-commodity content” into supposed proof that Google boosts anything original? I'm struggling to buy that argument, especially after looking at the example Google uses.

On one side you've got a broad article called “7 Tips for First-Time Homebuyers.” On the other, there's “Why We Waived the Inspection & Saved Money: A Look Inside the Sewer Line.” Sure, the latter sounds distinctive, but aren't we comparing two different kinds of searches here?

Someone researching a sewer-line inspection experience has a much tighter question than somebody looking for beginner homebuying advice. Different vocabulary, narrower intent, probably fewer competing pages. That changes the entire playing field before we even bring originality into it.

So what exactly are we measuring when the second article does well? Fresh information? Uniqueness? Closer relevance to a specific query? Less competition? A smaller pool of rival documents? Those explanations aren't interchangeable.

For AI-generated answers, I can understand why selecting sources that contribute something different would be useful. My problem starts when people treat Google's ability to detect novelty as proof that novelty independently moves organic rankings. Those are two separate claims.

Then there are SEO tools examining existing search results and scoring your content against them. They'll measure repeated phrases, distinctive n-grams, vocabulary differences, all that stuff. Fair enough, your article might look unlike the others. But where's the evidence that this difference explains its position?

Look at established, crowded SERPs. Pages covering the same subject inevitably start resembling each other. Writers research identical entities, borrow familiar structures, and repeat whatever points everyone considers essential. Meanwhile, obscure searches tend to produce fewer documents containing more specialized wording and less familiar details.

Couldn't that alone explain why heavily contested queries produce supposedly generic content while low-competition ones appear original? No special Google information-gain boost required. Just different search markets producing different patterns.

And designing a proper experiment sounds nearly impossible from outside Google. Imagine improving an existing page by adding information nobody else has included. Great, except you've simultaneously introduced terminology, entities, factual details, and new semantic connections.

Now the page potentially matches extra searches. It attracts different impressions, perhaps more clicks, and maybe its performance improves. How would anyone distinguish a reward for originality from ordinary increased relevance across a wider range of queries?

You're not changing one independent factor. You're altering what the document can be retrieved for, too. Unless somebody has access to Google's internal testing or ranking logs, how do you untangle that?

Source selection in AI systems is another story. Three references repeating identical information aren't necessarily as useful as a fourth contributing a genuinely new fact. That makes intuitive sense to me.

Organic rankings, though? I haven't seen convincing evidence that the same principle operates as its own independent signal. Pages with practically nothing written on them can rank, and sometimes a video embed alone is enough.

So am I overlooking something? Has anyone actually isolated information gain from search intent, query specificity, and competition in a credible test, without hand-waving or guesswork? Interested in hearing what others reckon.

What if Google's “non-commodity” content messaging isn't primarily about rankings, but about plugging holes in what's available online?

Think about AI Overviews. They need material to build answers from, right? Ten websites recycling the same generic advice aren't supplying much fresh insight. But get publishers sharing actual experiences, their research, specialist knowledge, and details nobody else has covered, and suddenly AI systems have a broader collection of useful sources.

None of that proves original pages receive special organic ranking advantage. Maybe Google benefits from having more varied information sitting there, ready for retrieval and citations.

Which makes me wonder: are SEOs treating advice about improving the...

Which makes me wonder: are SEOs treating advice about improving the available information supply as confirmation of a ranking signal, when the underlying message might simply be, “give us something we haven't already seen repeated everywhere”?
