Preview-first AI edits: read every line or trust the summary?

How closely to check an AI assistant's preview comes down to one thing: the summary is the assistant describing its own plan, so it always reads clean. For a small budget tweak, skimming the numbers and confirming is fine. For negatives, or anything touching a Smart Bidding target, I'd read the actual list line by line, because a summary that says "add 40 irrelevant terms" can hide one brand term that should never be excluded. The preview only works as a safety net if you check the raw changes and not the prose around them. Do you read every line, or do you have a rule for which changes get the full look?

I'd make it a rule too: read the raw diff when the change is irreversible or can quietly cost you money, like negatives and bid targets, and just skim anything you can undo in one click. The catch is that nobody can really eyeball a 40-term negative list. Sort it by match type first, or pull out the brand terms and anything with a high-intent word in it before you confirm.

I'd split it on where the terms came from. If the 40 negatives were copied from a search term report you've already gone through, with real clicks and conversion history behind each one, sorting by match type and scanning for brand terms is usually enough. If the assistant inferred them from the campaign name or a keyword list, read every line, because nothing in the data backs them up. The same list can deserve different levels of checking depending on that.

Agree with the split, but the date range matters too. A search term report only shows what happened in its window. Six clicks and no sales over two quiet weeks might just be a slow-buying audience, while the same term with zero sales over 90 days is a much stronger case. So a list built from a short window deserves more scrutiny than the source label suggests.

Negatives also fail silently. A bad bid change shows up in the spend line, but a bad negative just makes impressions disappear, and the summary never mentions the traffic it cost you. Before you confirm, check whether any of the terms sit close to keywords you're already bidding on, because phrase and broad negatives can block more than you meant.

How do you check what a new negative list actually blocked after a week?

The silent part is exactly where this goes wrong. After a week, compare impressions on your core keywords against the week before the negative went in. A phrase negative can quietly block a whole family of queries you still want, and Google's search terms view won't show you blocked traffic, so a drop in impressions is the only way you'll see it.
