Because everyone else is doing it and they feel like they need to do it. Also, statistics manipulation by said ad agencies. They do anything for conversion "attribution" metrics. Saw an ad 6 months ago and now you buy the product? That's tracked as a conversion by the ad company, telling the business how great their ads are doing. I'm convinced that a vast amount of sales attributed to online ads are sales that would have been made anyway.
