Coverage
Vivvix provides a monthly summary of the top 20,000 domains ranked on spending
across desktop & mobile devices. For each domain Vivvix reports the top 250 keywords
that drove paid search traffic to the domain, along with the estimated number of clicks
and impressions per keyword. All coverage reflects placements on Google and are
based on the results from local Google queries generated within the US.

Keyword Monitoring
Our observational data provides both breadth and depth of a brand’s search activity. In
the U.S. approximately 300,000 keywords are monitored daily, at least three times per
day, collecting information about the brands featured in the search results as well as
their relative ranking position.

Estimations
Some key variables are then inputted to estimate impressions, mainly click through rates
(CTR) and cost per clicks (CPC). The outputs of these models are combined to produce
search expenditure estimates for each advertiser / domain collected in its observational
data of brands. The model takes into account the brand’s frequency and position in the
search results related to each unique keyword. All models are periodically tested,
refined, and validated against known advertiser search spending.Spending estimates are based on the top 250 terms supported by the brand within the
monthly period, and as such may represent a subset of keywords the advertiser may be
supporting.
