When you set up an SSL certificate on your website, you can add a ‘site seal’ graphic to your website to show your visitors that their connection is encrypted.
For RapidSSL certificates (our most common cert), instructions are to simply download the image from the following link, then upload to any secure pages on your website – https://knowledge.digicert.com/solution/SO14424.html
Each type of certificate has its own Site Seal. Here is the full list of certs and their corresponding instructions – https://www.thesslstore.com/knowledgebase/ssl-site-seals/
If you have any questions on the above, please do not hesitate to 'Open a Ticket' and we will be happy to advise further.
