About MerchantCodex

Built by a practitioner,

The story

Why MerchantCodex exists

I started FeedArmy in 2014, helping merchants fix feed issues, recover from suspensions, and build Google Shopping campaigns that actually convert. Over the years, I answered hundreds of questions in Google’s official forums, eventually earning Diamond Expert status in both Google Merchant Center and Google Ads.

The problem I kept seeing: merchants and agencies trying to navigate Google Shopping with advice from AI-generated articles, outdated blog posts, or random Reddit threads. The wrong fix for a suspension can permanently disable your account. Bad information has real consequences.

MerchantCodex is my answer to that. A private community where you can ask real questions and get real answers, written by me personally, verified against Google’s actual documentation, and delivered in a format that becomes a permanent, searchable resource for the whole community.

No AI writes the answers here. No junior assistant handles your questions. You get me, every time, for every question.

  • I highly recommend using this service. We had a major problem with our online shop and the Google Merchant Center, and we were completely stuck. Emmanuel, with all his professionalism and experience, was able to help us solve it! He takes his time, works quickly, conscientiously, and is solution-oriented. We will definitely book Emmanuel for future projects because we know we’re in safe hands with him! Thank you so much!
  • We had a lot of issues with Shopify and Google’s own Google & YouTube app, including misrepresentation and similar problems.
    So we came across FeedArmy, and he recommended the Multifeeds app, which was a huge time-saver and easy to maintain. He also fixed all our feeds by using TSV instead of the Content API.
    Really helpful.
  • Very thorough. He set clear expectation on what services he could provide. Promptly responded to all messages as I worked through their report on corrections to make to the website.
