1. Select your campaign
Take a first look at the campaign’s performance. What stands out immediately? Are there any items that are performing poorly, or exceptionally well? Is the ACoS for a particular placement type higher than your target?
2. Analyse items
Items with a (too) high ACoS may not be successful. This could be related to the content about the item, the price, or the relationship with the payable cost per click (CPC). What can you do about this?
Automatic Campaign:
- Lower the target ACoS and, consequently, the costs. Note: this will result in fewer impressions and clicks.
- Exclude underperforming articles so that you have more budget available for the better-performing items.
Manual Campaign:
- Lower the bid for keywords with a (too) high ACoS. Use the “average winning bid” function to determine your ideal bid.
- Are you bidding below this average winning bid? Then the chances of winning the auction are low, but you will keep costs better under control.
- Are you bidding higher than this average winning bid? Then try lowering your bid in small increments to see if you can maintain similar performance at lower costs.
3. Optimise your keywords
Disable keywords that are causing a (too) high ACoS. In a manual campaign, if you notice that a keyword has a high ACoS but is still relevant to your product, first try lowering the bid for a better ACoS. If that doesn’t work, then disable it.
Note: Certain keywords are more expensive to advertise on than others, which can increase the costs of your campaign. Therefore, also pay attention to the impressions and clicks of your automatic keywords.
4. Check your categories
Disable categories that result in a (too) high ACoS or where you do not want to be visible. Running a manual campaign? You can also lower your bids for categories with a high ACoS.
If your goal is to optimise your ACoS and/or increase your return, focus on the best-performing categories.
5. Analyse product pages
Are the results from the product page not as good as hoped?
- Manual campaign: Consider lowering your bid for this placement and wait a few days before analysing again.
- Automatic campaign: Consider creating a separate manual campaign for this placement type, the product detail page, to set bids yourself.
