There are a few changes you can make if you're looking to improve the performance of your Kliken Ads | Shopping. You can make these changes from the Kliken Ads --> Manage --> Edit for your active campaign.
1. Update your interest targeting
Your interest targeting helps decide who to show your ads to based on what they love and are most interested in. If you're not getting a lot of traffic, try expanding your interest targeting to include more interests, as long as they relate to what you're selling. If you're getting a lot of traffic, but no sales, try narrowing down your interests targeting if possible.
2. Update your demographics
Demographics are a way to narrow down who sees your ads based on their gender or age. If you're not getting enough traffic, you may want to consider removing demographic filters as long as it makes sense for who you think is most likely to purchase your ads. If you're getting a lot of traffic, but no sales, you may want to consider narrowing down your demographics if it makes sense for who is most likely to purchase your products.
3. Location targeting
Location targeting is where your ads show. If you're not getting enough traffic, consider expanding your location targeting if you're able to ship your products to the available locations. If you're getting a lot of traffic but no sales, consider changing your location to a different area. If you have historic sales data that may suggest locations that are more likely to purchase, this is a good place to start.
