Fix the photo habit first, the marketing part is easy after that
None of this works without decent raw material. The fix is CompanyCam or a similar job-photo app, or even just a dedicated album in your phone's Photos app named by job address. Every crew member gets it on their phone. Every job gets a before shot, at least one during shot, and an after shot. Three photos, maybe 20 seconds of effort.
Before shots matter more than people think. A cluttered crawlspace, a rusted-out water heater, a roof with three layers of curling shingles, that's the photo that makes the after shot land. Skip it and you've got a nice picture of new equipment that means nothing to a stranger scrolling past.
Light matters too. Turn on the room lights or step outside before you shoot. A dim phone photo shot from a bad angle can't be saved by any AI tool downstream.
Turn one photo into a caption with a free AI tool
Pick one tool and stick with it. ChatGPT (free tier works, paid is about $20/month as of mid-2026) and Google Gemini (also has a solid free tier) both do this well: upload a photo and it writes text about what it sees.
Upload the after photo, or the before-and-after pair side by side. Then use a prompt like this, copy and paste it straight in:
- "I run a [your trade] company in [your town/county]. Write a short Facebook and Instagram caption for this job photo, 2 to 3 sentences, plain language, no corny hashtag string. Mention the type of job and the general area if it fits naturally. End with a soft call to action like calling or messaging for a quote. Don't make up details about the job I didn't tell you."
Build a week of content in one sitting
Instead of writing one caption at a time, batch it. Once a week, pull the 4 to 6 best photos from that week's jobs and run them through together. This is where you save the real time, the alternative is opening your phone every evening trying to think of something to post.
Upload all the photos in one message: "Here are 5 job photos from this week. Write a separate caption for each, same style as before: short, plain, mentions the job type and area, one soft call to action. Number them 1 through 5 to match the photo order." Paste the results into your phone's Notes app or a Google Doc, and now you've got a week of captions sitting ready.
Do this on a Friday afternoon or a slow Monday morning, whatever fits your week. Fifteen to twenty minutes, once, beats staring at a blank post box at 9pm trying to remember what you did on Tuesday.
The before-and-after post that actually works
Before-and-after is the single best format for a service business because it's proof, not a claim. Anyone can say "quality work," but a rotted deck board next to a new one does the talking for you.
Free tools that snap two photos into one side-by-side image: Canva (free tier, search "before and after" templates), or the built-in collage tool in your phone's Photos app. Keep it simple, a straight split, no filters, no text crammed onto the photo. Put the words in the caption instead.
For the caption, tell the AI tool it's a before-and-after: "This is a before-and-after of a [job type] in [town]. Write a caption that walks through what changed, why the homeowner needed it, and ends with a call to action." These posts tend to pull more comments and shares than a single after shot, because people like watching a problem get solved.
Where the content actually goes, and how often
You don't need five platforms. Pick two: Facebook and Google Business Profile matter most for a local service business, because that's where a homeowner checks you out before calling. Add Instagram only if you're already comfortable there.
A realistic cadence: 2 to 3 Facebook posts a week, one Google Business Profile update a week. Google rewards profiles that post regularly (see the guide on setting one up at /guides/google-business-profile-setup), and a stale profile with nothing new since March quietly slides down the results.
Use your phone or computer's native scheduling if the platform has it, Facebook Business Suite lets you schedule a week of posts in one sitting, free, or just post live if scheduling feels like one more app to manage. Either way, the batching you did on Friday means pasting a caption and hitting post, not composing one from scratch.
Keep the AI honest
Read every caption before it goes out. AI tools sometimes invent a detail that sounds plausible but isn't true, like guessing the age of a water heater from a photo or assuming a job took longer than it did. Cut anything you can't personally verify.
Never let a tool write a review or a testimonial (see /guides/get-more-google-reviews for the honest way to build real ones). The photos are real, the work is real, keep the words about them just as real.
