FAQPage Schema
How do I add meta tags and Open Graph tags to my Replit single-page app?▼

To add meta tags and Open Graph tags to a Replit SPA, the skill audits your source code and injects unique titles, meta descriptions, and social sharing tags into your HTML head or framework routing.

Why does my Replit single-page application show blank titles for crawlers?▼

Your Replit SPA shows blank titles for crawlers because client-side routing does not render head tags without JavaScript. The skill fixes this by implementing SPA prerendering, SSR, or route-specific meta tag injection.

What's the best way to generate a sitemap.xml and robots.txt for a Replit site?▼

The best way to generate a sitemap.xml and robots.txt for a Replit site is using an SEO audit skill that reads your project files and routing structure to automatically create these crawlability files and canonical links.

How do I add structured data and JSON-LD to my web app before deployment?▼

To add structured data and JSON-LD to your web app before deployment, the skill reviews your site type and injects appropriate schema markup into the HTML to improve search engine indexing and rich results.

Does this SEO optimizer require access to my project's HTML and JavaScript files?▼

Yes, the SEO optimizer requires read and write access to your project's HTML, CSS, and JavaScript files to modify head content, fix header structure, add image alt attributes, and implement routing-level SEO corrections.
