Let’s jump in to this week’s review of online advertising data.

Google announced that their ad revenue (at $39.6 billion) will be 5.3% lower in 2020 than 2019. Since ad market overall is growing (an estimated 1.7% to $134.7 billion), this means that Google’s share of the market will decline from 31.6% to 29.4%.

Digiday announced a study that concluded that site publishers are being paid later by their advertisers. About 25% of advertiser payments to publishers are being delayed under two weeks; 17% are being delayed between 14 and 30 days; and for 20%, more than 30 days.
