Website SEO Recovery Expert Needed

My website has recently experienced a severe drop in Google search performance. Several pages have been deindexed, and organic impressions have dropped close to zero. I am looking for an experienced SEO expert to investigate the issue, identify the cause of any Google penalties, and provide clear recommendations for recovery.

Scope of Work:
- Analyze Google Search Console and other relevant SEO data
- Identify possible manual actions, algorithmic penalties, or technical SEO issues
- Investigate deindexing causes (technical, content, backlink, or policy-related)
- Review site structure, content quality, backlinks, and recent changes
- Provide a clear diagnostic report explaining what went wrong
- Suggest step-by-step actions to fix the issues and recover rankings

Requirements:
- Proven experience handling Google penalties and deindexing issues
- Strong knowledge of Google Search Console, indexing, and ranking factors
- Ability to clearly explain findings and next steps
- Experience with technical SEO and content-related penalties is a plus

Deliverables:
- Written analysis of the issue
- Clear, prioritized recovery plan
- Optional guidance during implementation (if needed)
