I am looking for an experienced WordPress specialist to improve my website’s performance and ensure full compatibility with Google Merchant Center. The project scope includes optimizing the website speed and performance for both mobile and desktop, with a strong focus on Core Web Vitals and real user experience. The site must load quickly and efficiently without breaking existing functionality. In addition, I require a complete Google Merchant Center integration via API. This includes correctly syncing product data from the WordPress website to Merchant Center, fixing all product-related errors, warnings, and disapprovals, and ensuring that all products are fully approved and eligible inside Google Merchant Center. Scope of Work: Optimize WordPress performance for mobile and desktop (speed, caching, image optimization, Core Web Vitals). Audit and resolve technical issues affecting page load and usability. Connect the website to Google Merchant Center using a reliable API-based solution. Review and fix all product feed issues (titles, descriptions, pricing, availability, GTIN/MPN, images, policies). Ensure 100% product approval status in Google Merchant Center. Verify proper synchronization and ongoing feed stability. Acceptance Criteria: Noticeable improvement in mobile and desktop performance scores. Website runs smoothly with no functional issues after optimization. All products successfully approved in Google Merchant Center with no critical errors. Stable and accurate product synchronization via API. Please include your relevant experience with WordPress performance optimization and Google Merchant Center integrations when submitting your proposal.
