The issues covered are: inconsistent trailing slashes causing 301 redirects and broken Open Graph previews, duplicate content from migrating Medium posts without setting canonical URLs, and blindly trusting Gatsby plugins that incorrectly inject meta tags. Each problem is explained with concrete fixes, including disabling Netlify's Pretty URLs, adding canonical link tags to the HTML head, and verifying page source rather than relying solely on browser dev tools. ## Full article daily.dev links to this article rather than hosting it.
