So here I offer you to install a signed certificate to your website. I can install the certificate for you, and if you don't want to buy, I can create a signed certificate for you with 3 years max age (certificate tend to become vulnerable with age so 3 years is the max allowed time for a certificate in current scenario)
Install a signed certificate on your website, or if you only want a certificate for administration panel, then I can sign a certificate for you with my CA that you can add to trust list and enjoy secured connection.
If you're using wordpress, this is highly recommended, because this can greatly reduce spamming on your blog.
Also highly recommended for Joomla, Opencart, Magento, Drupal administrators who want to do the administration work securely.
