FAQs

What's the best way to monetize a website with ads?

The most effective approach combines multiple demand sources with high-impact ad formats that engage readers without disrupting their experience. Partnering with a premium ad network gives you access to advertiser demand you can't reach through open market alone, and contextual intelligence ensures those ads are matched to your content, which drives higher CPMs than untargeted placements.

What should I look for in a publisher ad network?

The two things that matter most are the quality of the demand and the quality of the support. A network with direct agency relationships and brand-name advertisers will consistently outperform one reliant on open market fill. Beyond that, look for integration flexibility, transparent reporting, and a team that actively helps you optimize – not just a tag and a dashboard.

How does header bidding increase publisher revenue?

Header bidding lets multiple demand partners bid simultaneously for your inventory, rather than sequentially as in a traditional waterfall setup. The result is genuine competition for every impression, which pushes CPMs up. GumGum supports header bidding via Prebid and Index Exchange adapters, and because our demand is unique to our network, we're adding competition that wasn't there before, not just reshuffling your existing bids.

What is high impact advertising and is it right for my site?

High-impact advertising refers to ad formats designed to be seen and engaged with, rather than scrolled past — including in-image, in-article, and online video units. For publishers, the advantage is clear: formats with higher engagement rates attract premium advertiser demand, which drives up CPMs. GumGum's high-impact formats are built to perform without being intrusive, so your reader experience stays intact while your revenue grows.

How can I monetize my video inventory more effectively?

Most platforms rely on URL or page-level data to target video ads, which misses a lot of context. GumGum analyzes video content frame by frame, reviewing audio, visuals, and metadata, to understand exactly what's on screen. That depth of understanding attracts advertisers who want precise, brand-safe placements, which translates directly into higher revenue per video impression.
