CAKE's test pages (on the offer and campaign) test the default offer link for that Offer. In order to test a specific creative link, you need to go test it through a campaign.
What you're testing
This is the creative-specific tracking link that you're using for that creative. It is visible in the "Link Override" column in the creatives tab.
Make sure that there is a campaign created for the Offer
Generate a campaign link for the creative you want to test
1. Click "Generate Link" on the campaign card
2. Select the creative you want to test, then 'NEXT' to generate the link
3. Copy the link
Test the campaign with the link you just generated
1. Clear cookies
2. Enable test mode
3. But instead of clicking on the test link on the page which would direct you to the default landing page, open a new tab or window and enter the creative-specific link you copied from the previous step
4. Test the campaign through to the thank you page
Check your Test Page for your test results
Your test page should have your click and conversion results as shown above.
You can also download the creative and open that creative in your browser, click on the creative (banner or email) to go to the landing page and test that way as well.
