Google Ads or local SEO: which comes first?

First the complete listing: hours, photo, category and phone, which the ad and the organic result share. The ad comes once that listing exists and someone types the trade; it does not cover an empty profile. Fix the listing this week and search your trade in the town. If other ads are already there, the spend has a place; if the listing is lying, the spend does not. The ad is paid for with a listing that has no hours, and the organic result does not convince either. The person comparing stays with the venue they can call. The listing up to date and, if the search exists, a search campaign with the same phone and the same photo. The order is written down: listing, then ad.
