Concentration and size in the title, one offer for each
A fragrance title has to carry brand, scent name, concentration and size, in that order. Eau de parfum and eau de toilette of the same scent are different products at different prices and must be separate offers, not variants of one listing, or the cheaper query lands on the wrong price and the click is wasted. Sizes get split as well, with unit pricing filled so the price per millilitre is visible, because that is how experienced buyers compare.
Campaigns split by how the shopper is searching. Note and family queries are discovery and belong on collection pages. Scent name queries are people who already know what they want, and they need the exact page with sizes and stock. Gift queries are a third structure entirely, with delivery cutoffs in the ad text as the season closes.
One rule sits above all of it. Never build ad copy or titles around another brand's name. Inspired-by and smells-like framing is a trademark problem and a counterfeit signal, and in this category it gets accounts suspended rather than warned.
