You insert banner tags on your site but no ad appears

 

Make sure:
- There is an active campaign on your account;
- The targeting zones of your campaign correspond to those of your Website;
- The geotargeting of your campaigns includes your own country.

Make sure the Adwit-express tag of your page corresponds to the one in your account (check for missing characters or punctuation marks).

Finally, check for JavaScript errors on your page. Any JavaScript error on your page may affect the performance or display of the display tag.
