When you create a campaign in Cool Tabs, with the Cool Promo or Cool Promo White applications, you have the option to include personalized messages. These will be displayed when the participant shares the campaign or her/his participation in social networks.
These messages are included in the 'Go viral' section of the campaign editor. However, if you modify any of these messages (title, text or image), once the campaign has already been published, you will notice that it still appears with the previous customization.

- Go to Facebook Crawler: https://developers.facebook.com/tools/debug/
- Include the URL of your campaign and click on Debug.
- Once updated, the information shown on Facebook when you share the link will be displayed as follows:
If you make changes again, enter the URL and click on scrape again.
