Is my website healthy?
The basics a visitor or a crawler trips over: broken links on the page, mixed content on HTTPS, a missing favicon, a 404 page that returns 200, no contact page, forms posting over HTTP, console-visible errors in inline scripts. Quick, broad, and the cheapest wins on the list.

Questions
What is a soft 404?
A page that says "not found" but returns a 200 status. Crawlers index it as a real page, your error page ends up in search results, and link errors go unreported. The error page must answer 404.
Why is mixed content a problem?
An HTTPS page loading an HTTP script or image lets the browser warn the visitor, block the resource, or both. Scripts are blocked outright, so a tracking tag loaded over HTTP simply never fires.
Does a missing favicon matter?
It shows in browser tabs, bookmarks and now in Google results on mobile. A missing one looks unfinished and causes a 404 on every page load. It takes five minutes to fix.
