My site runs on Google Ad Manager and the current AdX tags are dragging down page load times. The tags were recently placed, but Core Web Vitals now show a clear slowdown and users are bouncing. I need a specialist who can dig into the tag implementation, pinpoint exactly why the creative or GPT call is stalling, and restructure the setup so the ads still serve while the page stays fast. You’ll have full access to Google Ad Manager, the Google Publisher Console, and staging copies of the affected templates. Please audit every active tag, remove or rewrite any blocking code, and implement best-practice approaches such as async loading, lazy loading, or GPT single-request architecture where appropriate. Final output should be clean tags ready to deploy plus a concise report of what was changed and the performance gain verified through Lighthouse or similar tooling. Deliverables: • Optimized AdX/GAM tag set ready for production • Before-and-after performance metrics and brief summary of fixes I’m happy to test on staging the moment you supply the revised tags so we can sign off quickly once the speed target is met.

Hello, I can audit the current Google Ad Manager/AdX tag implementation and identify what is causing the page-load and Core Web Vitals slowdown. I have 10+ years of web development experience with JavaScript, PHP, HTML, CSS, MySQL, API integrations, and website performance optimization. I can review the existing GPT implementation, identify blocking or inefficient execution, and restructure the tags using appropriate asynchronous and lazy-loading techniques without breaking ad delivery. For 12000INR fixed, I can audit the staging implementation, optimize the affected tags, test the changes, and provide before-and-after Lighthouse/performance measurements with a concise summary of the fixes. I will work on staging first so the production implementation remains protected during testing. Estimated turnaround: 1–2 days. Milestone funded before development.

I'm a Backend & Web Developer and would be glad to take on this project. I'll audit every active tag in Google Ad Manager and the Publisher Console to pinpoint exactly why the creative or GPT call is stalling, then restructure the setup using async loading, lazy loading, and GPT single-request architecture so ads still serve while the page stays fast. Working in PHP, JavaScript, HTML and CSS, I can edit your templates directly and reserve ad space properly to prevent layout shift. You'll receive a clean, production-ready AdX/GAM tag set plus before-and-after Lighthouse metrics and a brief summary of every fix. I'm comfortable on staging and will supply the revised tags quickly for your testing, iterating until the speed target is met. Ready to start immediately.

Hi, slow AdX tags usually come from a blocking GPT script, too many slots requested at once, unreserved ad space causing layout shift, or a consent script delaying everything. I'd baseline your staging templates in Lighthouse, audit each tag, then load GPT asynchronously, use single-request architecture, lazy-load below-the-fold slots, and reserve slot heights. I'll confirm ads still serve in the Publisher Console. You'll get production-ready tags plus a short before/after report. Which CMS do you use, and do you run header bidding or a consent platform? I can start once I have staging access. Himanshu
