Frequently asked questions

Can AI create a month of social posts?

Yes. Tools such as SEO Runway draft a full month from your brand inputs. Plan to review and personalise each post before it's scheduled.

Is AI-generated social content effective?

It can be, when it's edited to include specifics such as your products, customers, photos and local details. Generic AI posts perform poorly.
