Meta Pixel and CAPI audit, potential fix - Shopify

We need an experienced Meta tracking specialist to check our store's Meta Pixel and Conversions API setup, for immediate start. Your audit tasks are to: 1. prove or disprove that data is flowing correctly between our store and our Meta Ads account 2. prove or disprove that Events Manager is properly de-duplicating events 3. prove or disprove that Meta Ads campaigns are able to trace conversions to ad clicks 4. After reporting on what is and is not working, fix each issue as necessary Please produce a report with brief written summaries, screencaps and/or screen-recordings. You may use Google Docs to do so or whatever is convenient to you. Context: We have two problems. 1. Events Manager appears to be double-reporting some events. Yesterday, for example, Events Manager reported 31 sales against Shopify's 18 sales. 2. Meta Ads campaigns are not attributing purchases to themselves. Taking yesterday again as example, campaigns only report 2 conversions in total. Requirements: ✅Proven experience with Shopify + Meta Pixel/CAPI integration ✅Able to make report on what is functioning and/or what is fixed ✅Conversational English To apply, please mention / have: - Good reviews for similar / identical work - Number of hours needed for the audit - Whether you can check deduplication & server-side event alignment - Shopify Partner profile
