What is your business model and how do you make money?
We're a global advertising marketplace where premium digital media companies sell their ad impressions in every channel transparently and in real time. Our ad exchange enables media owners to grow revenue and marketers to reach consumers on any screen, through any ad format.

Can you outline the full details of the agreement on a booking form / contract?

Will you share who your trading partners are?
We fully disclose this information to clients or potential clients.



Do you own the inventory you sell?

If you don’t own your own inventory then how do you access inventory and which platforms do you use?
We provide buyers access to publisher inventory through our own platform.

Do you specify your media placements and positions?

What insights do you provide back to advertisers?
Index Exchange offers detailed analytics so that media owners know exactly what their inventory is worth, and media buyers can see how each impression performs. At the advertiser or buyers’ request, we can provide an array of metrics and analytics (be they daily, weekly, monthly, annually, etc.) outlining performance, bids, efficiency, and areas for optimisation. In addition, buyers have real-time access to our UI, allowing them to view data pertaining to a variety of metrics (including spend, bids, etc.). We have also proactively created and shared customised dashboards for our buyers, giving them full access to analytics & receipts in relation to their use of our exchange. Furthermore, Index Exchange also provides Client Audit Logs (CAL) which are log level datasets, available via API that track all auction events for media buyers and owners.

Does the inventory you own or access include UGC content?
Yes, we do work with some publishers who have UGC content. However, we follow strict vetting procedures to ensure that all UGC on our publishers’ sites is actively monitored, flagging any activity that may raise brand safety concerns.

What brand safety measures do you use?
Index Exchange strives to operate an entirely fair exchange, employing an extensive initial and ongoing publisher verification process. We take proactive measures to ensure that all creative content, and content on media owners' sites, is compliant with brand safety requirements. Our Exchange Quality team verifies that all new creatives are reviewed and approved before activated onto the exchange. In addition, we leverage third-party verification partners such as WhiteOps, MOAT, and IAS to minimise exposure to fraud. Any media owner  that does not meet our quality standards will be blacklisted as necessary.

Which industry standards have you been certified against?
TAG Platinum Status for Independent Validation of IQG, Fraud, Piracy and Malware. In addition, IAB UK Gold Standard, JICWEBS and DTSG UK Brand Safety certified.

Do you have a policy in place for ad-misplacement?
Yes, as part of Index Exchange's commitment to a clean marketplace and delivering high ad quality standards, all ads, domains, and ad products are vetted to ensure they serve the publisher's needs and are not inappropriate. Index conducts human reviews on all creatives passing through the exchange and has procedures in place to ensure that media owners can review, edit, and provide feedback on the quality of their ads.
In the unlikely event that a media owner encounters an advertisement that does not serve the needs of their site, there is a protocol in place to quickly respond to any media owner  complaints. The Exchange Quality team will further assess the creative's general suitability to serve on Index and then determine the appropriate approach for investigating and resolving the issue. In addition, media owners  have the ability to block specific creatives or brands from displaying on their site through our IX platform.
