Amazon advertising success depends heavily on proper campaign structure and keyword organization. Many sellers struggle with amazon ppc optimization because they focus on arbitrary numbers instead of understanding search volume dynamics. This tutorial demonstrates why fewer keywords often mean better control over your amazon ads performance.

I walk through real campaign examples showing how high-volume keywords can dominate your amazon ppc ads budget, leaving other keywords without sufficient data. You'll see actual spend distribution across keyword groups and learn why the "cake slicing" analogy perfectly explains budget allocation in amazon pay per click advertising.

The video covers essential amazon ppc marketing concepts including granular control benefits, single keyword ad groups versus grouped approaches, and how search volume affects your amazon advertising campaign performance. Whether you're running sponsored products campaigns or broader amazon ads campaigns, these principles apply across all amazon advertising formats.

Real examples include a 9-keyword ad group where one keyword consumed 99% of the €332 budget, and a 32-keyword campaign with similar concentration issues. These cases demonstrate why amazon ppc agency professionals focus on search volume analysis rather than arbitrary keyword limits when structuring amazon advertising campaigns.

The insights apply whether you're managing amazon sponsored ads manually or through automated tools.

Hi guys, let's continue with the short tips on Amazon advertising. In today's episode, I will just try to cover something around campaign structure. So, how many keywords per ad group, but not just the number, I would like to share the reasoning behind it, how I see it and how we do it. So, uh there's no magic number like how many keywords you need to have in a campaign because it depends on the search volume. It depends on the intent. Is it a ranking campaign? Is it uh research or harvesting campaign or something else? Uh like a general rule, I can tell you that yes, the less the better because you you will have more granular control over what's happening that will enable you completely absolutely control on what's happening on placements. If you have a single keyword ad group that is like ideal campaign structure but you will may you may end up with tens of thousands of campaigns if that's your thing you can do that and you can do even do it manually you can do it with a tool but that also works it that's absolute control but you don't have to go that far but but you can maybe focus on five to 10 is a general I don't like to go more than 10 but again I will show you an example where even 10 is too much. But you have to know the context. You have to see what's the search term. Sorry, what's the search volume of of each keyword? So, let me give you a few examples. Take a look at this one. So, last 30 days here it is. It's it's nine keywords and out of €332 in last 30 days only this single keyword sorry this Yeah, the single keyword spent like 99% of the of the budget. It's simply because this keyword I had to hide it, but this keyword has the biggest search volume out of all of them. And that's why it draws the most of the of the budget. And that can happen doesn't matter if it's a 100 keywords. You just I like to uh explain it like you have one cake. So it's different if you have you have to slice that cake on 100 pieces or three pieces and there's there can be that there there's going to be five people who is going to eat that cake one uh one grownup man and four toddlers you know so who's going to eat more. So here this is the man among among the toddlers and he's eating too much of the cake so everybody else uh stays unhappy. So that's one of one example. So second example, same thing. Here's even um here 32 keywords but category targeting combined with keyword targeting where you again the same thing one targeting which is too broad with a with a high search volume combined with all the rest it creates problems. So here also more than 90% of spend is going towards the the most important keyword or targeting. Uh here it's not by itself such a problem because if it's a winning keyword yes you get good results you get good sales and you're happy here. Okay a cost is 8.49% with a good conversion rate 14%. And that's it. But you may think that you're targeting so many other keywords and on a campaign level you would say, "Hey, I'm killing it. No, this campaign is is is awesome and you're actually missing the point on all the other keywords, you know." So that that can really happen. And another point also, it's not just if you set six keywords per campaign that everything is going to be all right. Here you can also see that happens out of 5,400 3,000 went to the to the others. So um just wanted to give you context like don't follow the numbers like it's it's five keywords, it's 10 keywords, it's 100 keywords. If you put 100 K even if you put budget of a million dollars per day, that's not going to be good, you know, because one or two keywords going to spend that million dollars and all the others are not going to perform at all. So yeah, forward this video to your team if this is something that was interesting to you and see you in the next video. Bye-bye.

Frequently asked questions

Why is there no single correct answer to how many keywords should be in an Amazon PPC ad group?

The right number of keywords per ad group depends on the search volume of each keyword, the campaign objective, and whether you need granular placement control. A research or harvesting campaign targeting long-tail keywords with similar search volumes can accommodate more keywords without budget concentration problems. A ranking campaign for a single high-priority keyword should have only one keyword per campaign. The number itself is not the variable that matters; what matters is whether the keywords in a group have similar enough search volumes that no single keyword will absorb a disproportionate share of the budget and leave the others data-starved.

What is the budget concentration problem in multi-keyword campaigns and how does it affect performance?

When keywords with very different search volumes share the same campaign, the highest-volume keyword wins the majority of auctions and absorbs most of the budget. In the example from the video, a nine-keyword campaign with a 332 euro monthly budget had one keyword consuming 99% of that spend, leaving the remaining eight keywords with almost no data and no meaningful chance to show what they could do. A 32-keyword campaign showed the same dynamic, with one broad targeting option consuming over 90% of total spend. The result is that a campaign appears to be performing well at the campaign level because the dominant keyword may have good conversion rates, while in reality the seller believes they are actively testing and optimizing dozens of keywords when only one is actually running. This false sense of coverage is the core problem.

How should you restructure a campaign where one keyword is consuming nearly all the budget?

The dominant keyword should be isolated into its own single keyword campaign where it can receive a dedicated daily budget, placement adjustments, and bid management without affecting any other keywords. The remaining keywords, which have lower search volumes, should be grouped together in a separate campaign based on thematic or intent-based similarity. This gives each group an independent budget that is sized appropriately for its actual traffic potential. A keyword with ten times less search volume than the dominant term will never get meaningful data if they share a budget, but in its own campaign with a smaller dedicated daily budget, it can accumulate enough clicks over time to make a data-backed bid decision. The goal is that every keyword in every campaign has a realistic path to accumulating sufficient data to be optimized rather than being perpetually overshadowed.
