What to track in Amazon PPC

CPC stands for Cost Per Click. It's a metric used in online advertising to measure the effectiveness of an ad campaign.
It's calculated by dividing the total cost of the campaign by the number of clicks it generated. This gives you a sense of how much you're spending on average for each click your ad receives.
CPC is also used as a measure of ad quality. Generally speaking, the higher the CPC, the more effective the ad is at generating traffic and conversions. Conversely, low CPCs may indicate that an ad isn't resonating with users or that it's being targeted to the wrong audience.
By tracking your CPC, you can see how much you're spending on each click and adjust your campaign accordingly. Another reason to track CPC is to ensure that you're not overspending on specific keywords. If one keyword is costing more than it's worth, you can either adjust your budget for that keyword or exclude it from your campaign altogether.

CTR stands for "Click Through Rate". It's a metric that measures how often people click on a link, ad, or another call-to-action item. It is calculated by dividing the total number of clicks on an ad by the number of impressions (the number of times an ad was shown) for that ad.
It's essential to track CTR because it provides valuable insights into how well your marketing campaigns are resonating with your target audience.
If your CTR is low, it means people aren't clicking on your ads, which could mean they're not interested in what you're selling.
A high CTR usually indicates that a particular ad is resonating with its target audience and is providing them with what they are looking for. As a result, it's essential to monitor your CTR and make adjustments to your campaign if it falls below a specific threshold. By doing so, you can ensure that you're maximising the return on your investment in online advertising.

The conversion rate is the percentage of website visitors who complete the desired action, such as filling out a contact form or making a purchase.
The conversion rate is the most important measure of an ad’s performance. This means that you need to divide the number of sales by the number of clicks it received to calculate the average figure across all campaigns and platforms where it appears.
To improve your conversion rate, you'll need to identify what's preventing your visitors from completing the desired action and make changes to address those issues.
If you're running Amazon PPC, then you'll want to track your conversion rate to see how well your ads are performing. This will help you determine whether you need to make changes to your campaign to improve your results.

Cost Per Acquisition (CPA) is a metric used in online advertising to measure the amount of money spent to acquire a new customer. CPA is calculated by dividing the total cost of advertising by the number of conversions (such as sales, leads, or subscriptions) generated as a result of that advertising.
This metric can be useful for comparing different forms of advertising and identifying which campaigns are most effective at generating new customers.
However, it is essential to note that CPA does not consider the overall profitability of acquiring new customers, only the costs associated with advertising. Therefore, it should be used in conjunction with other metrics as well.
When it comes to Amazon PPC, tracking your Cost-Per-Acquisition (CPA) is essential for knowing how well your campaigns are performing.
