This thread raises a valid concern about managing multiple websites under the same Google Search Console (GSC) account. Here's a summary and clarification:
Key Points:
Separate Performance Analysis: Google evaluates each site's performance individually, regardless of being in the same GSC account. Having multiple sites in one account is not inherently harmful.
Sandboxing and Zero Impressions: These issues are more likely tied to SEO quality, duplicate content, or Google detecting similarities in site themes or backlinks. Focus on improving site-specific SEO and avoiding footprints.
Manual Penalties: As one user mentioned, penalties for one site can sometimes lead to scrutiny of others under the same account. While it's not a direct cause, sharing a GSC could highlight similar practices across sites, increasing risks.
Best Practices:
Separate Accounts for High-Risk Sites: If you have experimental or niche sites, consider managing them in separate GSC accounts.
Unique Content and Strategy: Ensure each site has distinct, high-quality content and its own backlink strategy.
Avoid Linking Too Closely: Avoid using the same hosting, Whois data, or interlinking sites excessively.
