1. Add photos. Tap Camera for a new one or Library to pick from your camera roll. A couple of photos is fine. Google only shows the one with the G.
2. Put the raw details in. Type or talk into the box. It gives you a couple of ideas of things to mention.
3. Tap Write it and it turns your words into a full post, in your voice, and looks at the photo too so it matches what's actually happening. Tap Post as is instead to use exactly what you typed, no rewrite.
Every post can carry one of your Google services, like Crane hire or Heavy item transport, worked into the words themselves rather than tacked on as a tag. Google reads that as real evidence you do that kind of work, so picking the right one, or fixing it with Change service if it's picked the wrong one, helps your listing show up for those jobs.
4. Read it over. Change anything you like. Tap Rewrite for another go.
5. Save as a draft, schedule it for later, or post now.
6. Drafts live under Drafts. Everything sent shows under Recent posts.
Posts go to Facebook and Google together. Google can take a few minutes to show it.
