Two similar products: one campaign or split?

global-expansion-pro

two products, one keyword pool, and a boss who wants both marketed. That's where I'm stuck.

The company I work for installs fiber cement siding and vinyl siding. Same service, different material quality and price point.

Our fiber cement campaign performed well, so the owner now wants to know if there's real value in going after vinyl customers too. My gut says two separate campaigns for cleaner tracking, but I'm worried about the two of them cannibalizing each other. Would negative keywords actually help with that?

The part that scares me is generic 'siding' searches. That's exactly where the crossover is going to happen, and there's no clean way to route that traffic yet.

Two campaigns, hands down. Ad groups in one campaign can work, but campaigns give you hard budget walls per product, which is exactly the control you want with two similar products.

The cross-match gets messy fast, so layer in negatives:

"vinyl" in the fiber campaign
"fiber" and "fibre" in the vinyl campaign

That routes most traffic where it belongs. The gap: bare "siding" plus some other qualifier can still match either product.

Revenue split matters here too. If vinyl is a minor line, one campaign with tight ad group structure beats the overhead of running two. Either way, if fiber is the priority, cap vinyl at 10-15% of budget and stick to exact match to start. cheap insurance until the search terms report shows what's actually converting

Here's the thing most people miss.

General search terms? They're expensive and messy.

Someone types "siding" - they're not ready to buy. They're researching. Comparing. Window shopping.

You send them to a generic page? You just lit money on fire.

Fibre cement buyers care about durability. Fire resistance. That premium feel. Vinyl buyers want affordability. Low maintenance. Fast install.

Totally different conversations.

Dedicated landing pages aren't optional. They're the bare minimum.

One campaign tries to speak to everyone - ends up speaking to no one. Two campaigns let you match message to motivation. Hook to pain point. Offer to budget.

Test it. The data won't lie.

ran two similar products myself, so I'd split them into separate campaigns. negative keywords decide where traffic lands, and budget control per product line becomes so much easier

Two campaigns. The key is cross-negative matching: put vinyl terms in as negatives on the fiber cement campaign, and fiber cement terms as negatives on the vinyl one. Without that, a broad query like "siding cost" gets matched to whichever ad set the algorithm happens to favor, and your budget bleeds in ways you can't control. Separate campaigns also let you bid to each product's actual economics instead of letting Google average them out.

Run one campaign but build dedicated landing pages for each product. Generic "siding" searches go to a general page, while fiber cement or vinyl queries land on the specific one. Negative keywords help, though broad match still bleeds traffic no matter what, so expect some mess.

For tracking, use separate conversion actions instead of splitting into two campaigns. Cleaner data and zero cannibalization headaches.

same approach here. We've got three pages: a general siding one that covers both options, plus dedicated pages for fiber cement and vinyl.
