Benefits of Parsec's Time-based Advertising

Less Risk

Media buys that use time spent as a pricing metric are more predictable and less risky because time spent is more closely correlated to attention than conventional metrics.

Consumer Choice

Consumers expect to control how long they engage with digital content, advertising that respects that same principal is much more effective.

100% Share of Voice

Parsec uses high impact ad formats that capture the full attention of the reader while in view.

Parsec's Network of Premium Publishers

Parsec media is sourced directly from our network of premium publishers with site-level reporting transparency. Our media specialists will work with you to select the perfect site list for your campaign. Additionally, Parsec can leverage first and third party data, or any other cookie-based audience data, to find your perfect audience.

Brand Case Studies

BMW 7 Series
Parsec worked with UM and BMW to produce creative that featured a 3D car rotator, expandable hotspots and embedded video content. Interaction rates were 3x over benchmarks and research saw double digit lift in purchase intent for consumers who chose to spend more than 4 seconds with the creative.

San Antonio Convention & Visitors Bureau
Parsec worked with Proof Advertising to create a rich media campaign that featured an scroll-based creative encouraging consumers to create unforgettable memories in San Antonio. Almost 17% of the audience reached chose to spend more than 7 seconds with the creative, and media optimization increased time spent metrics by 26% over the course of the campaign.

Parsec is Delivered Via theFormat

Politely Interruptive

Ads have to interrupt content in order to be effective, but interruptions can still be polite. The Sled format achieves this by giving the consumer control over the duration of the advertising experience.

Behaviorally Native

Like TV, print and social ads, Sleds are consumed using the same behavior as the content they monetize. This makes for a pleasant experience and smooth transfer of attention between the content, ad and back.

How Cost Per Second Works

Parsec is partnered with MRC accredited to measure time spent.

Time spent is only counted for impressions that reach the MRC threshold for viewability.
Time cap
Time spent ends after the ad exits the screen or at 15 seconds, whichever comes first.
There’s no charge for time spent in excess of 15 seconds per impression.

What Clients are Saying

I see buying media on a cost per time spent as the next and simplest evolution of media buying. By partnering with Parsec we remove all of the risk from our media buys and only pay for those consumers who are engaging a brand based on the time the ad unit was spent in view.
Benjamin Bring,VP, Media Director
The power of Parsec’s platform is consistency and simplicity — we pay for the amount of time that people choose to spend with our brands and that’s it.
Tim Mosback,VP, Partner, Universal McCann
Parsec has taken everything we thought we knew about mobile and has rewritten the status quo. Their solution is as important to our business as is it to the industry and the audiences that we ultimately serve.
Derek Lu,Associate Director
