As an AI language model, I can’t predict the future, but…

I can provide insights based on trends observed up to my knowledge cutoff in September 2021. In the out-of-home (OOH) advertising sector for 2023, several factors could be important:

1. Post-pandemic recovery: The OOH industry will continue to recover from the pandemic and adapt to new consumer habits. This could involve targeting ads to locations where people are starting to congregate again, such as public transportation hubs, malls, and entertainment venues.

2. Digitalization: The shift towards digital OOH (DOOH) will likely continue, with more digital billboards, screens, and dynamic content. Advertisers will increasingly use programmatic ad buying, real-time data, and analytics to optimize campaigns.

3. Personalization and targeting: As data-driven technologies evolve, OOH advertisers will look to improve personalization and targeting capabilities. This could include using geolocation, mobile data, and other data sources to deliver more relevant ads to consumers.

5. Sustainability: As environmental concerns grow, the OOH industry will likely focus more on sustainability. This could involve using eco-friendly materials, energy-efficient technologies, and promoting green initiatives.

6. Creativity and innovation: OOH advertisers will need to constantly innovate to capture consumer attention. This could involve using new technologies like augmented reality, interactive displays, and other engaging formats.

7. Measurement and analytics: The OOH industry will increasingly focus on improving measurement and analytics capabilities to better understand ad performance, optimize campaigns, and demonstrate ROI to clients.

These factors are not guaranteed to be relevant in 2023, but they reflect trends and developments that could have a significant impact on the OOH sector in the coming years.
