If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
Do you mean you want a 'Like' button on your site for people to like your Facebook page? If so, insert some code into an HTML widget. There are many customizations for this box, which can be found here.
Because of this I cannot give you the complete code, as you'll need to fill in your page URL and customizations.
I hope this information was helpful! Please let me know if you need further assistance with adding this to your site.
