Choose the right tool

Each link opens one independently usable free utility, with its own description, manual input, methodology and result. Work from your own data, save useful results, and verify any marketplace decisions in the official account before publishing changes.

How to approach the checks

Start with your highest-impact issue, confirm the source data is current, and resolve concrete errors before optional recommendations. If you manage a large catalog, keep copies of the original feed before editing. Automated account integrations and continuous monitoring are not active in this release.
