My WordPress-based store has hit a critical snag: when shoppers add or remove items, the cart total refuses to refresh and the checkout stalls. I need this “cart not updating” bug traced and eliminated so the full payment flow runs smoothly on every device. Once the technical fix is in place, I’d like to keep momentum by tightening the entire sales funnel—building a focused landing page for an upcoming Google Ads push and polishing on-page SEO so traffic converts immediately after the ad click. Deliverables: 1. Cart update issue resolved, with a brief root-cause report. 2. End-to-end checkout tested through to payment confirmation. 3. Conversion-oriented WordPress landing page designed, published, and linked to existing tracking pixels. 4. Quick-win SEO and Google Ads recommendations to support the new page. If you’re comfortable working inside WordPress, debugging AJAX or caching conflicts, and can pivot straight into performance marketing, let’s get this live.
