The plunge in the UK economy in Q2 2020 due to the pandemic-induced lockdown reduced advertising expenditure by close to one-third, recovering in Q3.

Impaired mobility of consumers dramatically reduced expenditure on print and out-of-home media, which are reliant on footfall, alongside cinema, whose theatres have been shuttered on and off all year.

The paradigm shift in consumer expenditure to ecommerce in 2020, which will moderate in 2021 as mobility partly returns, boosted online display while search was flat due to impeded travel plans.

In response to COVID-19 and the associated lockdown and economic crash, advertisers have slashed budgets. Online budgets are not immune.

This has clarified features of the online ad market: it is demand-driven, relies heavily on SMEs and startups, and is built on direct response campaigns.

We expect online advertising to outperform other media, and for platforms to further gain share. But with a very few exceptions, this health and economic disaster is good for nobody.
