Before you launch your shiny new website, use these tools to make sure that your site is compliant, secure, high performing, and can be easily discovered by your audience.

Social Media Card Testing

Tests to see how your site will look on social media feeds when someone shares or posts it. Just enter your website address and they will show you the results.

Security Scanning

Scans your site's infrastructure configuration to ensure that your site is safe and secure. You can also allow third-party tests to be run from Observatory. For example, a scan from ImmuniWeb will check if your site has SSL vulnerabilities.

SSL Labs

Scans your site for SSL/TLS misconfigurations and compliance.

Webmaster Search Console

These tools allow you to directly submit your website for search engine indexing. They also provide tools to measure the mobile-friendliness of your site. If you opt-in, they will periodically send you e-mail notifications if they detect an error on your site that would reduce search engine optimization.

Below are the three most popular options. Note that you will have to prove that you own your domain or are the owner of the website either by providing a specific DNS entry in your configuration or by adding a temporary meta tag to your site.
