Opti Engage

Level-up your Header Bidding game

Access top-tier bidders with a single integration and increase your revenue through dynamic banners.

Connect your ad inventory to leading bidders on the market through a single integration and boost your revenue.

Opti Engage by Opti Digital is an innovative ad technology that connects your inventory to top bidders in a single integration through Prebid. It increases ad space monetization by splitting placements dynamically into several impressions compatible with any media type (native, display, video) and by making the inventory available to server-side header bidding auctions.

Dynamic banners

Opti Engage helps publishers add value on existing ad placements rather than adding new ones. We gather creatives from bidders in real-time and transform them into rich formats via dynamic ad templates, allowing you to achieve high inventory eCPMs without cluttering user experience or increasing page load time.

Increase revenue

Grow your ad request eCPM by up to 12% by leveraging multiple bids for every impression through dynamic templates.

No new format required

Compatible with standard IAB sizes. No need to add new formats or to change the behavior of your existing placements (refresh rate etc…).

Minimize your ad stack

Integrates leading bidders on the market, allowing you to simplify your Header Bidding setup as well as your invoicing process.


In a context of deprecation of third party-cookies and where the market moves towards server-to-server, our solution comes as a standard Prebid.js + Prebid Server integration.


Our dynamic templates are A/B tested to ensure viewability rate and click-through rate remain unaffected despite multiple ads being displayed instead of one.


Opti Engage allows publishers to boost their revenue per impression and increase the share of header bidding amongst all demand sources (Google Open Auctions, Amazon A9,…) translating into more revenue in absolute value.

  • Fetch bids from leading SSPs in real-time
