Question

Silly question: what are the benefits of splitting your product categories into different campaigns? For example if you sell bathroom stuff, then you would have a "basins" campaign with basin-related ad groups (marble, freestanding etc. ) And you could have a "Toilets" campaign toilet-related adgroups (smart, affordable etc). We have taken over a few accounts recently that have shown this trend. Normally the only time we split the campaign's is if we want to target locations or devices, or even control spend.  

Answer 1

The more relevant the results when someone searches the better your CTR and Lead cost is.

@guitar48 but does the relevancy extend to a campaign level? I mean surely having relevant ad groups is enough? Personally we use SKAG (*everyone gasps*) and that allows us to have tons of relevant ad groups in one campaign

I do the same. Say I have a home improvement store, I’d have a campaign for bathrooms, appliances, tools, etc. then in each campaign I’d have an adgroup with relevant terms for the given items being searched for and ads tailor to those search results. Sounds like we both do the same thing. Not sure what you mean by relevancy extending to campaign level. The only thing I do campaign level is budgets, locations, etc. beyond that it’s all ad group level.

So are you saying that because your campaign only has "bathroom" related ad groups and keywords that Google finds that campaign more relevant than a campaign that has ad groups for bathrooms and tools and applicances all lumped together ?  

---

No, I’m saying relevancy is based more on your webpage, Ad group, keywords, and ads than campaign.  

Answer 2

You can't setup budget on ad Group level for example.

You can use product groups.

@kehoe48 you cant allot a budget on product group level.  

Answer 3

More granular budget and location optimisation

Comments

@carmelcarmela79 yeah that's what's I was also thinking. So correct me if I am wrong, but you would only really take this approach if the client has enormous budgets right?

I would probably do it in most cases

Answer 4

Better quality score. This is a fundamental best practice of Google Ads.

This can be achieved by separating into ad groups.

Much more targeted
