Here is a question worth asking about any page on your site. If ten other articles already say exactly what this one says, why would Google, or an AI, choose yours?
Most of the time the honest answer is: it wouldn't. And that single test explains more about why content does or does not rank in 2026 than any amount of keyword tinkering. Google has a name for the idea. They call it information gain. It is the shared currency that both traditional search and large language models now use to decide what is worth surfacing.
What information gain actually means
Google was granted a patent describing an "information gain score", a measure of how much new information a document adds compared with the pages a user has already seen on a topic. The principle is simple. The first article to explain something is valuable. The tenth article repeating it adds nothing, so it earns nothing.
AI search works on the same logic, just from the other direction. A model like the one behind Google's AI Overviews or ChatGPT is trained on huge amounts of text. It has, in effect, already read the ten generic posts. When it looks for a source to quote, restating the consensus is useless to it. What it needs is the fact, the number, or the opinion that is not already everywhere. That is the thing it cites.
So both systems are running the same filter. Does this page tell me something the others don't? If yes, it has a reason to exist. If no, it is invisible, no matter how neatly it is optimised.
The four things that add information gain
You do not need to be a professional writer to clear this bar. You need to put something on the page that a generalist rewording competitor cannot. In practice that means one or more of the following.
- First-hand experience. What actually happened when you did the thing. The mistake you made on your first Shopify migration. The step every guide skips. Lived detail cannot be paraphrased from elsewhere because it did not come from elsewhere.
- Real data. Even small, honest numbers count. "We looked at 40 local service enquiries and 7 in 10 came from mobile" is more citable than any polished paragraph of generalities. Use figures you can actually stand behind.
- Named opinions. Take a position and sign your name to it. "I think most small businesses waste money on broad match" is a view an AI can attribute and a reader can weigh. Fence-sitting content gives neither of them anything to hold.
- Original examples. A worked scenario, a real before and after, a specific case. Concrete beats abstract every time, and it is the part no competitor can copy without doing their own work.
Notice that none of these come from a keyword tool. They come from knowing your subject and being willing to say something.
How to audit your existing content for sameness
Most sites do not have a content shortage. They have a sameness problem. Go through your key pages and, for each one, ask three blunt questions.
- Could a competitor have published this word for word? If yes, it carries no information gain.
- Is there a single specific fact, number, example, or opinion on the page that is genuinely yours? If you cannot point to one, that is the gap.
- Would an expert reading this learn anything, or nod along and close the tab?
Score each page honestly. You will usually find a familiar split. A small number of pages have real substance. A larger number are competent, tidy, and completely interchangeable. Those interchangeable pages are not just neutral. They dilute the site, because they signal thin, me-too content across the whole domain.
Why one original post beats ten rewrites
This is the part business owners resist, because publishing volume feels like progress. It usually isn't.
Ten rewrites of what everyone already says give both Google and the AI ten reasons to ignore you. One post built on a real project, with a number you measured and an opinion you will defend, gives them a reason to quote you specifically. It gets cited, it earns links because it says something linkable, and it keeps working long after the rewrites have sunk.
If you are choosing where to spend limited time, spend it going deeper on fewer topics you genuinely know. Interview the person in your business who does the work. Write down the thing they say that no article contains. That is your information gain, and it is the whole game.
When we plan content as part of an SEO engagement, this is the first filter we apply: not "what keyword", but "what can we say here that no one else can". It is slower to produce and far harder to ignore.
