Google Merchant Center (GMC) may flag your site as "Untrustworthy" due to:
Misrepresentation Issues:
Inconsistent pricing, shipping, or return policies between your site and product listings.
Missing contact information (email, phone, physical address).
Website Compliance Problems:
No SSL certificate (HTTPS) → Secure browsing is required.
Poor user experience (broken links, slow load times, unclear navigation).
Lack of Business Transparency:
No About Us, Terms & Conditions, or Refund Policy pages.
Vague or misleading product descriptions.
Fix: Align product details, enhance transparency, and ensure your website meets Google Shopping policies.
