AdWords help needed: Should I: 1) create separate CAMPAIGNS for each product and AD GROUPS with variations of different match types and keywords in it? This means few AD GROUPS but many CAMPAIGNS. or 2) create one CAMPAIGN and place all products along with variations of keywords inside in separate AD GROUPS? This means dozens of AD GROUPS in one CAMPAIGN.
What's the best practice?
To be precise, I offer some AV equipment for hire (rent). I have quite many different categories. Currently I keep them all in one Campaign and created Ad Groups for each product.
Now, I want to differentiate them by creating separate Ad Groups for words "hire" and separate for words "rental". All this to be more relevant in terms of Ads.
Another thing is - should I separate mobile CAMPAIGNS from desktop ones? Or should I keep both devices in the same CAMPAIGN but in different AD GROUPS, or do not differentiate mobile devices from desktops at all?
