Likely to be nearly identical to Google’s text ad format, Amazon Text Ads will probably utilise keyword-based targeting.
The ad parameters and character counts will probably be identical to Google and many of the campaign structure and settings will be similar.
It is rumoured that you will also be able to upload your Google campaigns direct to Amazon too.
This will change the game for those of us selling ecommerce products. I'm looking forward to the changes as i've already built a six-figure a month business using amazon ads (and a few other things too).
Keep your eyes open for announcements.
Good luck with your ventures.
