This may deter site visitors who use your website as they may interpret the "Not secure" warning message to indicate that your website has been compromised and not safe to use. They could also think that your site has some security issue other than being non-HTTPS.
If you do not adapt to these new changes from google the amount of conversions on your website could decrease as people are less likely to use the website if it isn’t trusted and secure which also effects your customers perception of the company. Not having the appropriate certificate on your website will also effect Search Engine Optimisation and your Google page rankings.
To avoid any issues with these changes and to keep your website secure it is important that you get the appropriate SSL certificate on your website you would need to transfer your website and content over be served over SSL. There are 3 types of certificates available:
Extended Validation (EV) SSL Certificates –
available for all types of businesses, including government entities and both incorporated and unincorporated businesses. A second set of guidelines, the EV Audit Guidelines, specify the criteria under which a CA needs to be successfully audited before issuing EV SSL Certificates. The audits are repeated yearly to ensure the integrity of the issuance process.
Organization Validation (OV) SSL Certificates –
The CA checks the right of the applicant to use a specific domain name PLUS it conducts some vetting of the organization. Additional vetted company information is displayed to customers when clicking on the Secure Site Seal, giving enhanced visibility in who is behind the site and associated enhanced trust.
Domain Validation (DV) SSL Certificates –
where the CA checks the right of the applicant to use a specific domain name. No company identity information is vetted and no information is displayed other than encryption information within the Secure Site Seal.
You would also need to redirect all HTTP URLs across to secure HTTPS URLs, then submit a new SiteMap to webmaster tools.
