As an online entrepreneur, you’re continually looking for opportunities to boost your brand visibility and drive sales. But in the vast, dynamic marketplace that is Amazon, how can you ensure your products stand out and reach the right audience?

Enter Amazon PPC (Pay Per Click) campaigns, a powerful tool to put your products in front of customers actively looking for your offer. However, success doesn’t just come from just launching a campaign and hoping for the best. It requires continual monitoring, analysis, and optimisation to ensure you get the best return on your advertising spend.

So, how exactly do you monitor Amazon PPC campaigns for optimal performance? Grab a cup of tea, sit back, and let’s journey through the ins and outs of PPC monitoring.

Understanding the Amazon PPC Landscape

Let’s kick off with what Amazon PPC campaigns are. They’re a significant component of Amazon’s e-commerce ecosystem. By creating these campaigns, Amazon sellers can advertise their products and services on the platform. Whenever a potential customer clicks on the sponsored ad, you pay a certain fee; hence the term ‘Pay Per Click’.

Imagine this: you’re a seller with a vast catalogue of hiking boots. You’ve noticed a significant rise in hiking enthusiasts and want to tap into that market. So, you decide to promote your product through an Amazon PPC campaign. Whenever a potential customer searches for ‘hiking boots’, your product appears at the top of their search results. If they click your ad, voila! You’ve just attracted a possible sale, and Amazon charges you a small fee.

Importance of Monitoring and Managing These Campaigns

But here’s the thing – while setting up a PPC ad on Amazon might be relatively straightforward, the true art lies in monitoring and managing these campaigns. Why so? The answer is quite simple. You’re competing against countless other sellers advertising similar products, all vying for a click from the same pool of customers. Therefore, it is important to keep a keen eye on your PPC campaigns to understand their performance and ensure you’re not wasting your advertising budget on ineffective strategies.

You might liken monitoring PPC ads to tending a garden; it involves ongoing work. You’ll need to water and prune regularly, and occasionally, you might have to change the soil or add fertiliser. Similarly, observing campaigns involves daily tasks such as checking performance and identifying underperforming keywords. It also consists of larger weekly or monthly tasks like evaluating trends or adjusting budgets.

Key Metrics to Monitor

Let’s first understand the parameters you need to keep an eye on when evaluating your Amazon PPC campaign strategy.

Impressions and Click-Through Rate 

Impressions and the Click-Through Rate (CTR) are like the bread and butter of Amazon PPC monitoring. Impressions measure how many times your ad appears in front of potential customers. If you’re getting a high number, your ad is frequently seen in users’ searches – a good sign of visibility.

However, impressions alone don’t paint the whole picture. You could have a million appearances in search results, but if nobody clicks on your ad, they aren’t very valuable. That’s where the CTR comes in. 

CTR is calculated by dividing the total number of clicks your ad receives by the number of impressions, then multiplying by 100 to get a percentage.

For example, if your ad was shown 1000 times (impressions) and it was clicked 50 times, your CTR would be 5%. That means, on average, for every 100 times your ad appeared, it was clicked on 5 times. The higher the CTR, the more appealing your ad appears to potential customers.

Cost Per Click and Advertising Cost of Sale 

Cost Per Click (CPC) tells you how much you’re spending each time someone clicks on your ad. This figure is influenced by the competitiveness of your chosen keywords and the amount you’ve bid for them.

For example, if you’ve set a maximum bid of £1 for a term and Amazon charges you 70p each time a customer clicks your ad, your CPC is 70p.

Advertising Cost of Sale (ACoS), on the other hand, is a measure of the efficiency of your ad spend. It’s calculated by dividing your total ad spend by the revenue generated from your ad, then multiplying by 100 to get a percentage.

For instance, if you spent £100 on advertising and made £400 in sales from those ads, your ACoS would be 25%. That means for every £1 you earned from ad sales, you spent 25p on advertising. Generally, a lower ACoS is more desirable as it indicates you’re spending less to make a sale.

Conversion Rate and Return on Ad Spend 

The conversion rate is a crucial indicator of how well your ad resonates with customers once they’ve clicked on it. It’s calculated by dividing the number of sales by the number of clicks, then multiplying by 100 to get a percentage.

For instance, if you received 100 clicks on your ad and made 10 sales, your conversion rate would be 10%. If this rate is low, it could suggest that although your ad is compelling enough to earn a click, the listing or the product itself may not meet the customers’ expectations.

Return on Ad Spend (RoAS) is the flip side of ACoS. It’s calculated by dividing the revenue from ad sales by the ad spend. So, with the previous example of £400 revenue from £100 ad spend, the RoAS would be 4. This implies that for every £1 spent on advertising, you received £4 in revenue.

Total Sales and Total Spend

While the aforementioned metrics offer insights into various aspects of your PPC campaign, the big picture boils down to two figures – total sales and total spend.

Total sales refer to the amount of revenue generated directly from your ad, while total spend is the amount you’ve invested. Comparing these two figures can give you an immediate sense of your campaign’s profitability. If you’re spending more on the campaign than you’re making in sales, it’s a clear indication that some aspects need revising.

Tools for Monitoring Amazon PPC Campaigns

Understanding the performance of your campaign, from impressions and CTRs to conversion and overall profitability, is crucial for making informed decisions and optimising your advertising efforts. However, manually tracking these metrics can be a complex and time-consuming process. Fortunately, there are several tools designed specifically to facilitate the monitoring and management of Amazon PPC campaigns. 

Amazon’s Advertising Console and Reporting Features

Amazon provides a useful in-house tool for sellers to monitor their PPC campaigns – Amazon’s advertising console. This platform offers a wealth of information. You can view detailed reports of your sales, impressions, clicks, CTR, CPC, ACoS, and much more. The console presents data in a digestible format, enabling you to spot trends and make data-informed decisions.

Third-Party Tools and Software for Advanced Analytics

If you’re looking to dive deeper into your campaign analytics, third-party software can be a game-changer. Tools like SellerApp, Helium 10, and Jungle Scout offer advanced PPC analysis features that can provide valuable insights.

For instance, these tools can help you identify which keywords drive the most sales, determine the optimal times to run your ads, and even give you recommendations on how to alter your advertising campaigns based on your specific objectives.

Importance of Data Tracking and Analysis

Data tracking and analysis are fundamental for the success of any Amazon PPC campaign. The raw data you gather from your ad contains a goldmine of information that can help you improve your ad copy, enhance your listings, and, ultimately, improve your return on investment. Let’s delve into why they’re so crucial.

Identification of Patterns and Trends

Through regular tracking and analysis of data, you can start identifying patterns and trends. Maybe your ads perform better on weekdays compared to weekends. Or perhaps you see a surge in impressions and conversions during specific hours of the day. By understanding these trends, you can adjust your PPC ad to ensure that your ads run optimally during high-performance periods.

Making Informed Decisions

Data doesn’t lie. And when you’re allocating budgets, deciding bids, or selecting keywords, you want your decisions to be as accurate as possible. With detailed data at your disposal, you can base your decisions on factual information rather than guesswork.

Let’s say your data indicates that a particular set of search terms yields a high ACoS and low conversion rate. It might be time to reconsider these keywords, adjust your bid, or enhance the relevant product listings.

Measuring the Success of Changes

When you make changes to your PPC campaign, whether it’s adjusting bids, altering ad schedules, or experimenting with different keywords, data analysis allows you to measure the success of these changes.

You’ve reduced the bid on a word or phrase from £1 to 80p. But has that impacted your ad’s visibility? Has it affected your CTR or conversion rate? With continuous data tracking, you can answer these questions accurately and decide whether further adjustments are necessary.

Understanding Your Audience

Last but not least, data analysis can provide invaluable insights into your target audience. 

  • Which products are they most interested in? 
  • What keywords are they using? 
  • At what times are they most active?

This information can guide not only your PPC ads but also your broader marketing and sales efforts.

Remember, the key is not just collecting data but turning it into actionable insights. Regular data tracking and analysis enable you to stay nimble, responding to trends and making informed decisions to optimise your Amazon PPC campaigns.

Daily Monitoring Tasks

It’s important to create a clear procedure for checking the performance of your Amazon PPC campaigns. Hence, in this section, we’ll cover several daily activities you can do to keep ad campaigns on track.   

Regularly Checking Campaign Performance

Make it part of your daily routine to check the performance of your Amazon PPC campaigns. Key metrics like impressions, clicks, CTR, CPC, and ACoS can change rapidly. A daily review of these figures will help you quickly spot any sudden shifts or anomalies.

If you notice a sudden spike in impressions but a drop in CTR, this could suggest that while your ad is visible to a large audience, it needs to be more enticing for users to click. On the other hand, if you notice an increase in CPC, it could indicate heightened competition for your chosen keywords.

Identifying Underperforming Keywords and Adjusting Bids

Each day, note the keywords that are not performing up to par. These could be terms with a low CTR, high CPC, or low conversion rate. Once you’ve identified these underperformers, consider lowering your bids on them or even pausing them altogether.

Remember, a high-cost keyword that doesn’t result in conversions can quickly drain your ad budget. Adjusting bids is not a one-time task but an ongoing process of refinement and optimisation.

Monitoring Ad Placements and Optimising Campaigns

Amazon offers a variety of ad placements, including top of search, product pages, and rest of search. Each placement can yield different results, and it’s crucial to monitor the performance of your ads based on their location.

For instance, you might find that your ads perform better when placed at the top of search results compared to product pages. With this knowledge, you can alter your campaigns by adjusting bids to secure high-performing placements.

Tracking Competitor Activity and Adjusting Strategy

Monitoring your competition is a vital aspect of any Amazon PPC campaign. Keep an eye on your competitor’s product listings, prices, and sponsored ads. Tools like Jungle Scout and Helium 10 offer competitor tracking features that can help you stay on top of your game.

Are your competitors using keywords that you hadn’t thought of? Have they lowered their prices, impacting your conversion rate? By tracking their activity, you can make necessary adjustments to stay ahead.

Weekly and Monthly Monitoring Tasks

Alongside your daily ad checks, you should also carry out more extensive reviews on a weekly or monthly basis. Let’s dive into some of these monitoring tasks. 

Evaluating Overall Performance Trends

While daily checks are great for spotting immediate issues, a weekly or monthly review can reveal overall trends. How has your CTR changed over the month? Has your ACoS improved?

Understanding these trends can help you plan your future campaigns. For instance, if you notice that a specific ad consistently performs well on weekends, you might consider increasing your bids on those days.

Adjusting Budgets and Bid Prices Accordingly

Weekly and monthly reviews also provide a perfect opportunity to adjust your overall budgets and bid prices. At this stage, you’ll be able to see more detailed statistics on how your keywords are performing after several days or weeks. For instance, if you notice that a particular campaign is performing exceptionally well, it may be worth increasing its budget. On the other hand, if a campaign continually yields a high ACoS, it might be time to lower your bids or reconsider your keyword strategy for that campaign.

Analysing Keyword Performance and Making Necessary Changes

Keywords are the backbone of your Amazon PPC campaign, and their performance can significantly impact your ad success. Since your data will be more extensive compared to daily checks, you can use your weekly and monthly reviews to analyse your search term performance in depth.

For example, are there keywords that consistently outperform others? Consider increasing your bids on these high performers. On the other hand, if certain keywords cost you more than they’re worth, it might be time to pause them or adjust your investment.

A/B Testing Ad Copy and Creative Elements

A/B testing, or split testing, compares two versions of an ad to see which one performs better. Experimenting with ad features can be an effective way to improve your PPC campaigns.

Try testing different ad copies, images, headlines, or call-to-actions. After running the tests for a sufficient amount of time, analyse the results and implement the winning elements in your campaigns.

Strategies for Boosting Amazon PPC Campaigns

Now you understand how to monitor Amazon PPC campaigns, it’s time to optimise. Consider following these strategies to improve ad performance. 

Continuously Refining Keyword Targeting

Refining your keyword targeting should be an ongoing process. Conduct thorough research using tools like Amazon’s keyword planner or third-party software. This will help you discover new opportunities that you may have overlooked.     

Utilising Negative Keywords to Enhance Campaign Performance

Negative keywords are a powerful tool for improving the performance of your PPC campaigns. These are the words and phrases for which you don’t want your ads to show. By setting negative keywords, you prevent your ads from appearing to users who are unlikely to convert, saving your ad budget for more relevant clicks.

For example, if you’re selling high-end designer shoes, you might want to add “cheap” or “discount” as a negative term to avoid showing your ad to users looking for bargain deals.

Testing Different Ad Placements and Targeting Options

Experiment with different ad placements and targeting options, such as on the top-of-search and product pages, where you may get more targeted traffic. You might find that your ads perform better in certain places than others, so make sure you have tested all possibilities.

Similarly, try out other targeting options. For example, you can focus your ads on specific keywords, product categories, or individual ASINs. Different targeting options can yield different results, so don’t be afraid to get creative and find what works best for your products.

Regularly Updating Ad Copy and Images

Lastly, keep your ad copy and images fresh by regularly updating your listings to highlight additional features or benefits of your product. Furthermore, test various headlines, descriptions, and call-to-actions. You might find that more assertive messaging works best for your audience or that they prefer infographic images. With that in mind, always use high-quality, appealing photos that accurately represent your product. Don’t be afraid to experiment with image types, like lifestyle or product close-ups, and see what resonates best with your target market.

Troubleshooting Common Issues

Anyone who has managed Amazon PPC campaigns before will know that you’ll undoubtedly run into issues. However, with a little guidance, you can avoid these and be on your way to boosting ROI.

Problematic Keywords and Low CTRs

If you’re dealing with problematic terms or low CTRs, there could be several underlying issues. Start by analysing your keyword performance. Are there any search terms with particularly low CTRs? If so, it might be time to pause or adjust your bid.

In terms of ad copy, ensure your ads are enticing and relevant to the user. Use persuasive language, highlight the unique features or benefits of your product, and include a strong call-to-action.

High Advertising Costs and Low Conversion Rates

High advertising costs and low conversion rates are common issues for many Amazon sellers. To tackle this, begin analysing your ACoS. If it’s higher than your target, consider lowering your bids or refining your keyword strategy.

For low conversion rates, examine your product listings. Is your product competitively priced? Are your product images high quality? Does your product description accurately describe your product and its benefits? Improving these aspects can help boost your conversion rate.

Ad Disapproval and Policy Violations

Ad disapproval can be frustrating, but it’s often due to policy violations. Ensure that your ads comply with Amazon’s advertising policies. This includes guidelines on prohibited content, restricted products, and ad copy requirements.

If your ad is disapproved, Amazon will typically provide a reason for the disapproval. Review this reason carefully and make the necessary adjustments to your ad. If you’re unsure of the issue, don’t hesitate to contact Amazon’s support for clarification.

Case Studies and Success Stories

Real-life experiences provide the best insights into how to monitor Amazon PPC campaigns for success. The following case studies from our work here at NUOPTIMA will give you a taste of the possible outcomes and strategies when managing Amazon advertising effectively.

Case Study 1: 96North Candle Brand Grows 4x from $300k to $1.2m Revenue at 12% TACOS

Consider the story of 96North, a 100% soy wax candle brand that began selling on Amazon in August 2020. Upon acquisition, we faced the challenge of growing a niche brand dangerously close to stock out. We approached the task with a multifaceted plan of action that included:

  • Cleaning up their PPC campaigns for efficiency.
  • Refining their listing for optimal appeal.
  • Enhancing review gathering and visibility for increased consumer trust.
  • Adjusting product pricing for competitiveness.

One of our early successes involved the keywords ‘candle’ and ‘candles’. Despite their high competition and CPC, our careful monitoring and testing showed promising results. Emboldened, we increased ad spend on these two keywords alone and witnessed an incredible growth of 101% in total product volume from July to August ($47,415 in July vs. $95,585 in August).

Moreover, our longtail keyword strategy was another triumph. We targeted phrases like ‘vanilla candle’, ‘vanilla scented candle,’ and ‘vanilla soy candle’. The result was an impressive $4,714 in revenue from just $1,467 in spend, with a cost of sale standing at a reasonable 31.13%.

Within a year, 96North’s revenue grew fourfold, from $300k to $1.2m, maintaining a Total Advertising Cost of Sale (TACOS) at 12%. The takeaway from 96North’s success is the importance of thorough keyword analysis and optimisation, coupled with constant testing to maximise ad spend efficiency.

Case Study 2: Hex Performance: Six-Figure Sales in Just 8 Months

Then there’s the story of Hex Performance, a sports laundry detergent brand. When Hex Performance partnered with NUOPTIMA, their primary goal was to enhance their visibility on Amazon. With our expertise in PPC, Hex Performance could optimise its advertising budget, maximising its ROI.

The challenge we faced was to balance PPC and organic search term performance. Initially, our approach was to increase keyword bidding aggressiveness. However, the analysis revealed that while we spent more on PPC, it cannibalised their organic keyword performance. We then adjusted our approach to balance PPC efforts with organic strategies for a more holistic and effective sales approach.

During these 32 weeks, Hex Performance experienced an impressive 6x ROAS, generating six-figure PPC sales while maintaining an improved 17% ACOS. This successful partnership underlines the importance of a well-balanced strategy between organic and paid performance, coupled with continual analysis and adjustment based on performance data.

These case studies show how monitoring Amazon PPC campaigns and responding promptly to the insights can drive success in the competitive marketplace. No matter the challenges your brand faces, with careful planning, strategic action, and constant analysis, it is possible to turn your ad campaigns into a substantial source of revenue and growth.
