Folks one more update for Data.com
You will want to change id to id15 because data.com won’t allow you to select records and add the back to the account if you use the 18 character ID, See updated below
https://na4.salesforce.com/DataDotComSearch?id={{{Id15}}}&jid={{{JigsawCompanyId}}}&name={{#urlEncode}}{{Name}}{{/urlEncode}}
again replace na4 with your instance
