Google Merchant Center Optimisation for 4 Website Accounts

I’m looking for an experienced Google Merchant Center specialist to review and optimise four separate GMC accounts, each linked to a different website my company operates. All accounts have already been set up, but they need refining to ensure they run smoothly, remain error‑free, and perform as effectively as possible.
Project Requirements:

Audit all four Google Merchant Center accounts
Identify and resolve feed errors, disapprovals, and warnings
Ensure each feed is fully compliant with Google Shopping policies
Optimise product data to improve visibility and performance
Review account structure, shipping settings, tax settings, etc.
Provide recommendations for continued optimisation and best practices
Link them to Google Ads and Analytic accounts (setting these up where not currently in existence)

What I’m Looking For:
Strong experience managing and optimising Google Merchant Center accounts
Understanding of product feed formatting, attributes, and policy compliance
Ability to troubleshoot issues and implement fixes efficiently
Clear communication and attention to detail

Additional Info:
This job covers four accounts, each for a different website
I’m looking for a freelancer who can ensure everything is running correctly and efficiently
There may be ongoing work available as we continue to expand our ecommerce presence

If you're confident you can help streamline and optimise these accounts, please get in touch — ideally with examples of previous GMC optimisation work.
