How long should a caption be?

As long as it needs to be, but the first line matters most, because the feed hides everything after roughly 125 characters behind "more". A single strong sentence often beats a paragraph. If you have more to say, say it, just make sure the opening line stands on its own.

Do I need to use hashtags at all?

Not really. Instagram has said hashtags do not increase reach, and it now favours around five specific ones at most. The keywords in your caption do more for discovery. Add a few relevant tags for your trade and town if you like, but do not lean on them to carry a post.

What should the first line say?

One useful or surprising thing, on its own, before the reader taps "more". Ask the question they already have, correct a myth, or promise a specific payoff. Avoid openers like "another busy week" that give nobody a reason to keep reading.

Is it okay to use ChatGPT to write my captions?

Yes, as a first draft. It is good at getting words on the page when you are stuck. Just edit the result back into your own voice, cut the corporate phrasing, and add the specific detail only you know. A caption that sounds like everyone else's does not build trust.

How do I write captions when I feel I have nothing to say?

Pick one of five shapes: a customer question answered, a myth corrected, a before and after, a quick tip, or a behind the scenes note. Each one turns an ordinary day at work into a post, and it tells you which photo to take while you are there.

Should every caption ask people to book or call?

No. Most posts exist to keep you familiar, not to sell that day, and a hard ask on every one wears thin. Save the direct call to action for posts with a real offer or deadline. A question to the reader often does more, because it invites a reply.

How do you write a caption when you hate writing?

The short answer

Start with the first line, because that is the only part the feed shows before the reader taps "more". Say one useful thing, the way you would to a customer at the counter. Pick a repeatable shape, keep it to a single idea, and let the photo carry the rest.

The first line is almost the whole job

Instagram collapses a feed caption after roughly 125 characters, and on a Reel it shows around 55 before it cuts to "more". That first line is the hook. It decides whether anyone reads on or scrolls past, so most of your effort belongs there, not in the paragraph underneath that many readers never open. If the opener only says "another great day at the shop", there is nothing to tap for.

A good first line does one job. It asks the question the reader already has, states a number, corrects something they believe, or promises a specific payoff. "The one thing that ruins a new fence in year one" earns a tap. "We love our customers" does not.

What a first line has to do

Make sense on its own, before anyone taps "more"
Carry the single most useful or surprising thing you have to say
Sound like a person, not a press release
Fit inside roughly 125 characters on a feed post, fewer on a Reel

Five caption shapes you can reuse forever

The blank box is the problem, not your writing. You do not need a fresh idea every time. You need a shape to pour today's photo into, and five will cover almost any post you make.

Rotate through them across the week and your feed stops sounding like the same sentence on repeat. Each shape also tells you what photo to take, which is usually the harder half of the job.

Shapes that always work

A real customer question, answered. "How often should I actually service my boiler", then the honest answer.
A myth corrected. "You do not need to whiten before a clean", and here is why.
A before and after. What it looked like, what you did, what changed.
A quick tip. One thing the reader can do themselves, given away for free.
A behind the scenes note. Why you chose that grout, or what went wrong and how you fixed it.

Write the way you talk, one idea at a time

Read your draft out loud. If you would never say it to a customer standing in front of you, cut it. "We are thrilled to announce" is not how you talk. "We finally got the new chairs in" is. The plainer version sounds real, and real is what people trust from a local business.

Then check that the caption is about one thing. A post that mentions a new service, a seasonal offer and your opening hours asks the reader to hold three thoughts, so they hold none. One idea, one photo, one reason to care. If you have three things to say, that is three posts, which is a good problem for a feed that needs feeding.

Go easy on the call to action

You do not need to end every caption with "call now" or "link in bio". Most posts are there to keep you familiar, not to close a sale that day, and a hard ask on a soft post reads as needy. Save the direct call to action for posts that have earned it: a real offer, a booking window, a genuine deadline.

When you do ask, ask for one small thing and make it easy. "Ring the number in our bio and we will book you in this week" beats "get in touch to discuss your requirements". A question aimed at the reader, like "what colour would you have gone for", often does more work than an instruction, because it invites a reply, and replies are the signal the platform rewards.

The honest state of hashtags

Hashtags are not the reach lever they were sold as. Instagram's head, Adam Mosseri, has said plainly that hashtags are not a way to get more reach, and the platform now points you towards around five at most. What moves discovery is the words in your caption, the ones a search or the feed can read as keywords, together with saves and shares.

So write the caption for a human first, and let it happen to contain the words someone might actually search. A caption that says "emergency plumber in Tampa" does more for you than ten tags. Add a few relevant hashtags if you like, keep them specific to your trade and your town, and stop counting on them to rescue a weak post.

Use an AI assistant to draft, then edit it back to human

If the blank box is what stops you, an AI assistant like ChatGPT is good at getting a first draft on the page. Give it the facts of the job, the shape you want and the plain voice you use, then treat what comes back as a rough draft, never the finished caption.

The edit is where you earn it. AI writing has a house style: smooth, a little corporate, fond of "elevate" and "in today's world", and readers have started to recognise it on sight. Cut those words and put back the detail only you know, the customer's name, the thing that went wrong, the reason you did it that way. A caption that could only have come from your business is the one that works.

A prompt that gives you something usable

Tell it what you do and where, in one line
Give it the shape, such as customer question, myth, or before and after
Paste the actual facts of this job or photo
Ask for three short options under 125 characters
Rewrite the best one in your own words before you post

Templates you can adapt today

Swap the details for your own. Keep the shape of the first line intact, because that is the part doing the work.
