You have three pages half answering the same question. Google picks one, usually not the one you would have chosen, and the other two quietly drag. Nobody wants to run the audit because its output is a list of things to delete, and deleting feels like admitting waste.
Search your own site for your main terms, one at a time. If more than one of your pages comes back for the same search, that is cannibalisation and it is self inflicted. Your traffic does not split evenly between them, it collapses towards the weakest.
Two thin pages on the same question make one good page. Move the useful parts into the stronger URL, redirect the weaker one to it, and you keep whatever the old page had earned instead of throwing it away.
Send a link or a draft. We reply with what to cut, what is missing and the one number it needs. One email, no call.
Changing the date at the top and reordering two paragraphs is not a refresh, and readers can tell within a screen. A refresh adds a number that was not there before, removes advice that has stopped being true, and says what changed.
A page with no traffic, no links and no purpose is not neutral. It spends crawl attention, it dilutes what your site is about, and it makes every audit after this one longer.
This is teaching material and our own reading of standard editorial practice, not advice for your specific business. Check anything important with your own specialist before you act on it.
A published page, a draft, or the topic you are stuck on. An editor reads it and writes back with what to cut, what is missing and what number it needs. No call, no pitch.
