A common question is how long a change takes to show. The FAQ already answers it, and the answer is specifically about the feed and the structure, not about results in general.
Feed and structure improvements typically show measurable impact within 4 to 8 weeks, as Google's AI relearns on the new data. The full architecture takes longer: its benefits (brand-level segmentation and automated classification) compound over 3 to 6 months as the data builds up.
The page Google Ads for multi-brand resellers gives the same two ranges. They come from the FAQ and are not a deadline for any given account.
The shorter window covers the feed and the structure. The longer one covers the architecture, with brands separated and classification automated. All of this follows the method on our homepage: Refine, Test, Automate, Scale. Automate means daily product classification, custom label updates and feed maintenance, and that is the work the weeks and months above refer to.
The original FAQ question is How long does it take to see results?.
