KDP Advertising: How to Reduce Wasted Spend and Protect Royalties

KDP advertising is a crucial aspect of any self-publisher's marketing strategy, but it can be frustrating when you're not seeing the desired return on investment. One of the primary concerns for KDP authors is ACOS, as it directly affects their royalties. When ACOS is high, it means that the cost of advertising is eating into the author's profits, leaving them with little to no royalties. In this article, we'll explore how to reduce wasted spend and protect royalties in KDP advertising.

What Counts as Wasted Spend in KDP Advertising

Wasted spend in KDP advertising refers to any ad spend that does not generate a return on investment. This can include impressions that do not lead to clicks, clicks that do not lead to orders, or orders that do not generate enough sales to cover the cost of the ad. To identify wasted spend, KDP authors need to closely monitor their ad metrics, including Spend, Clicks, CPC, Orders, Sales, ACOS, and Royalties.

For example, let's say you have a KDP ad campaign with the following metrics:

Metric Value
Spend $18
Clicks 20
CPC $0.90
Orders 0
Sales $0
ACOS 100%
Royalties $0
In this example, the ad campaign has a high ACOS and zero royalties, indicating that the ad spend is being wasted.

Royalties vs Ad Spend: The Math KDP Authors Miss

When it comes to KDP advertising, many authors focus on ACOS without considering the impact on their royalties. To truly understand the effectiveness of their ad campaigns, authors need to calculate their per-book profit and ensure that their ad spend is not eating into their profits. This can be done by using tools like InteliAds, which provides authors with detailed insights into their ad campaigns and helps them optimize their ad spend.

By understanding the math behind their ad campaigns, authors can make informed decisions about their ad spend and ensure that they are not wasting money on ineffective ads. For example, if an author's per-book profit is $2.50, they should aim to keep their ACOS below 50% to ensure that they are not losing money on their ad campaigns.

Keywords That Look Fine in ACOS But Bleed Profit

Some keywords may appear to be performing well in terms of ACOS, but may actually be bleeding profit due to high CPC or low conversion rates. To identify these keywords, authors need to closely monitor their ad metrics and adjust their bid caps and negative keywords accordingly. This can help to reduce wasted spend and improve the overall profitability of their ad campaigns.

Negatives, Bid Caps, and Pause Rules

To reduce wasted spend and protect royalties, KDP authors can use a combination of negatives, bid caps, and pause rules. Negatives can help to prevent ads from showing for irrelevant keywords, while bid caps can help to control ad spend. Pause rules can be used to pause ad campaigns when they are not performing well, helping to prevent further wasted spend.

For example, an author may set a bid cap of $0.50 to prevent their ad spend from getting too high, or set a pause rule to pause their ad campaign if the ACOS exceeds 50%. By using these tools, authors can help to reduce wasted spend and improve the profitability of their ad campaigns.

Dry Run Before You Change Live Bids

Before making changes to live bids, KDP authors can use dry run features like those offered by InteliAds to test their ad campaigns and identify potential issues. This can help to prevent wasted spend and ensure that ad campaigns are optimized for maximum profitability. By using dry run features, authors can simulate their ad campaigns and identify areas for improvement before making changes to their live bids.
