SEO Recovery for Deindexed Site

I run several manga websites built on plain HTML, with no recent content or structural changes. Overnight, all organic traffic vanished because every page was suddenly de-indexed. I receive DMCA takedown notices on a regular basis, yet many larger manga sites in the same niche keep ranking, so I know it’s possible to stay visible. I need an SEO specialist who has already restored de-indexed or penalized sites—ideally in copyright-sensitive niches—and can implement safeguards so the same wipe-out doesn’t happen again. What I’m looking for: • Full technical and off-page audit: crawl-ability, server logs, Search Console data, backlink profile, and any manual-action traces. • Root-cause report that explains exactly why the de-index occurred (algorithmic filter, manual penalty, DMCA fingerprinting, or something else). • Action plan and implementation: fixes to on-page SEO, structured data, robots directives, canonical tags, duplicate-content handling, and safe link clean-up. • DMCA-aware strategy: methods other high-volume manga sites use to stay compliant or mitigate takedowns without losing rankings. • Post-recovery monitoring: re-submission, index status tracking, and contingency steps if new notices arrive. Please share real examples of sites you have rescued from de-indexing or heavy penalties. I value a transparent approach, documented milestones, and clear evidence that the recovery is sustainable.
