We already have an example in the plugin.
[eaa_ads]
First ad
<!– next_ad –>
Second ad
<!– next_ad –>
third ad
[/eaa_ads]
The separator between the ads should be exact.
<!– next_ad –>
If you still can’t get it to work, please share your url.
FYI: Ad rotation means it will show different ad on each load or page refresh.
