What are the practical benefits of choosing a top SSP over a traditional ad server?
+Top SSPs expand demand sources beyond direct deals, enabling more buyers to compete for your impressions in real time. This generally improves fill rates and CPMs, while offering richer analytics, controls for brand safety, and unified reporting across multiple demand channels. The trade-off can include setup complexity and the need to balance latency with competition for bids.

<div class="faq-question">
<h3>How does header bidding interact with the biggest Ssps?</h3>
<span class="faq-toggle">+</span>
</div>
<div class="faq-answer">
<p>Header bidding creates a single auction where multiple SSPs bid in real time before the ad server decides which ad to serve. This increases competition and can boost revenue. The exact impact depends on the mix of demand partners, integration method (client vs server‑side), and latency management. A well‑configured setup fishhooks high‑quality demand without compromising user experience.</p>

<h3>Can a publisher switch between SSPs, and what does the migration involve?</h3>
<span class="faq-toggle">+</span>
</div>
<div class="faq-answer">
<p>Yes, many publishers rotate or optimize between SSPs to maximize yield. Migration typically involves updating ad tags or header bidding configurations, testing latency and fill rates, and setting up new demand partners. It’s wise to run a staged pilot, measure impact on RPMs and latency, and maintain direct deals to protect revenue stability during the transition.</p>
