Site has no JSON-LD structured data
Add JSON-LD structured data to homepage. Minimum: Organization + WebSite. Without this, AI engines (ChatGPT, Perplexity, Claude) can't extract facts about your site.
Site missing og:url tag
Add canonical og:url to homepage and every shareable page. Without it, social shares may use the URL with tracking params, splitting your social signal across duplicates.
Site has no sitemap.xml
Create /sitemap.xml at the root of your site listing every public URL. Submit to Google Search Console. Reference it from /robots.txt.
Site missing canonical URL
Add a canonical link tag to every page. Prevents duplicate-content penalties when the same page is reachable via multiple URLs (with/without trailing slash, query params, etc.).
Site has no meta description
Add a meta description, 150-160 characters, that hooks the reader and includes the page's primary keyword. This is what shows under your title in Google results.
Site has no robots.txt or empty robots.txt
Create /robots.txt at the root. At minimum, allow all + reference your sitemap. Without it, AI crawlers and search engines have no explicit policy to follow.
Site title too short (under 30 characters)
Expand the title tag to 50-60 characters, leading with the page's main value proposition + brand. Short titles lose CTR in SERPs.
