Tons of clicks and no conversions, not even on retargeting All Visitors or Adwords Optimized list on display ads. The same when I created similar audience of All Visitors, 1 conversion first $30 spent but then $400 spent and no conversions. I did not enter any specific targeting such as keywords, platforms, etc. Any recommendations I can follow? I am sure I can learn from you more than asking hundreds of Google specialists. I believe display ads have potential even though their AI algorithms cannot be compared to Facebook.
