SSP Comparison

Stellor Media vs. Sharethrough — Which SSP is Right for Your Site?

Comparing a managed publisher-first SSP against an attention-economics SSP for web publisher monetization.

Sharethrough is an independent SSP known for its work on attention metrics, Enhanced Formats, and carbon-conscious bidding. They serve a wide range of web and CTV publishers and have invested heavily in deal curation and identity.

Stellor Media is a publisher-first SSP focused on managed onboarding, dedicated yield optimization, and a publisher-aligned commercial model — purpose-built for mid-market web publishers who would rather have a partner than a platform.

When to Choose Stellor Media

Frequently Asked Questions

Can I run Stellor Media and Sharethrough together?
Yes — they compete inside the same Prebid auction. Adding a second SSP usually increases competition without cannibalising the existing one.
Does Stellor Media offer Enhanced Formats?
No. Stellor focuses on standard OpenRTB display, video, and native delivered via Prebid.js. If your monetization strategy depends on bespoke creative formats, Sharethrough is purpose-built for that.
How does sustainability factor into supply path?
Stellor reduces hops via direct demand and a curated partner roster. We don't currently offer formal carbon scoring; that's a Sharethrough strength.
