Optimization Strategies

Lazy Loading Implementation

Load ads only when they enter or approach the viewport

Implement Intersection Observer for ad containers

Set loading threshold at 200-500px before viewport

Prioritize above-fold ads for immediate loading

Use placeholder divs to reserve space

Header Bidding Optimization

Minimize latency from header bidding auctions

Set timeout between 400-800ms

Use server-side bidding for additional demand

Remove slow or underperforming bidders

Implement bid caching where possible

CDN Configuration

Optimize content delivery for faster ad loading

Use CDN for all static ad assets

Enable compression (gzip/brotli)

Set appropriate cache headers

Use HTTP/2 or HTTP/3 where available

Caching Strategies

Reduce redundant requests and improve load times

Cache bid responses where allowed

Implement service worker for repeat visitors

Use browser caching for ad scripts

Cache consent decisions locally
