Why is my new website on GitHub Pages flagged as a dangerous site in Chrome?

Make sure you've enabled HTTPS for your site! If it’s only accessible via HTTP, that could trigger the warning in Chrome. Check to see if your custom domain is set up correctly with HTTPS.

This is typically due to Google flagging the site as a security risk or false positive. Here's what you can do: 1. Check the Google Safe Browsing Transparency Report to see how it's categorized (malware, phishing, etc.). 2. Verify your domain through Google Search Console and look for any security issues. If there’s nothing major, request a review. 3. Sanity-check your site’s content; sometimes sites that look phishing-like get flagged. 4. If you think it’s a mistake, file a report that your site is incorrectly flagged.

It sounds like you may need to activate and set up SSL correctly. Ensure your SSL certificate is in place because that’s usually the root of these warnings. GitHub Pages offers free SSL with Let's Encrypt for your domain, so you shouldn’t have to purchase one separately!

Honestly, without the link to your website, it's hard to tell! But this kind of flagging usually relates to Google’s Safe Browsing reputation rather than an issue specifically with GitHub Pages. It could be a false positive. If you can share your site’s link, that would help us offer better advice!
