How many of your posts should actually sell something?

Most advice on how often to promote on social media small business owners will find was written for brands with a marketing team. You have a van, a phone and maybe ten minutes at lunch. So the plan has to be simple enough to keep going in a busy month.

An offer post is a post that asks people to book, buy or call now, usually with a price, a deadline or a limited number of slots. Everything else on your feed is there to make that offer believable when it shows up.

Why Selling in Every Post Backfires

People follow a local plumber, roofer or salon to see the work and get a feel for who they'd be letting into their home or chair. A feed that's nothing but discounts reads like a business that's short of work. That's the last thing you want a homeowner to think.

And your posts land in a daily habit. Pew Research Center found that 37% of US adults visit Facebook several times a day. If most of what they see from you is a pitch, they learn to scroll past, and platforms tend to show people less of what they keep skipping.

Younger customers are using your page to check you out. BrightLocal reports that 1 in 4 Gen Z consumers use social media as their primary way to search for local businesses. When they land on your profile, they want to know one thing. Do these people do good work?

You can run this yourself with a phone and a calendar reminder, or hand the making and posting to a done-for-you social media service. The mix below holds either way.

How Often Should a Small Business Promote on Social Media?

Sell in about one post out of every five or six. Split the rest roughly evenly between useful posts and proof posts. That's the whole rule.

At three posts a week, a month looks like this.

• Five useful posts
• Five proof posts
• Two offer posts

At four posts a week, it looks like this.

• Six useful posts
• Seven proof posts
• Three offer posts

Space the offers out. Put each one after a run of proof posts, so someone who has just seen a finished install and a glowing review meets the offer already trusting you.

If you only manage one post a week, skip offers in some months and run one well-timed offer each season. Treat all of this as a starting point. After two or three months, look at which posts brought calls and messages, and shift the mix toward what works for your town and your trade.

What Counts as a Useful Post

A useful post answers a question your customers already ask you on the job. It saves them a call, or it tells them when they should make one. Both make you the business they remember.

Some examples by trade.

• HVAC. When to change a filter, and what a rattling outdoor unit usually means.
• Plumbing. How to find and shut off the main water valve before you need to.
• Electrical. Why a GFCI outlet keeps tripping and when it's time to call someone.
• Roofing. What to check from the ground after a storm, without climbing a ladder.
• Salons. How to make color last longer between appointments.

The easiest way to find these is a note on your phone. Every time a customer asks whether something is normal, type it in. Each question is a post. A short video of you answering it beside the van often feels more real than a polished graphic.

Proof Posts Do Most of the Selling

Proof posts show your finished work and what customers say about it. They do the persuading, so your offer posts don't have to.

Reviews carry a lot of weight. BrightLocal's 2026 review survey found that 97% of consumers read reviews for local businesses, and 32% look for reviews written in the last two weeks. So recent proof counts, and a steady trickle beats one big post a year.

Job Posts

Take a before photo before you touch anything. Then take the after. That one habit gives you a carousel for most jobs. Add a line on what you found, what you did and the neighborhood (with the customer's okay, and never the house number). Old water heater out, new one in, floor swept. People like seeing a tidy finish.

Review Posts

When a good review comes in, turn it into a post. Put the review text over a photo of that job and thank the customer by first name if their review is public. Reply to the review on Google too, so people who find you there see the same care.

How to Make an Offer Post Without Sounding Desperate

Desperate sounds like 'Slow week, call us now!!' or a discount with no reason behind it. Confident sounds like a busy business with a few openings and a good reason to fill them.

Give a Real Reason

Tie the offer to the season or your schedule. Furnace tune-ups before the first cold snap. AC checks in spring. Roof and gutter inspections after the leaves drop. Holiday color appointments for a salon. Or simply 'Two install slots left before Thanksgiving.' A reason makes the offer feel like news.

Show the Work First

Lead with a photo or clip of the job the offer is for. A clean new panel or a finished bathroom does the selling. The offer itself can be one line under it.

Be Specific and Set an End Date

Say exactly what's included, who it's for and when it ends. 'Whole-home surge protection installed, homes in Westfield, booked by the end of November.' Vague talk of great deals reads as filler.

Give One Next Step

Call, book online or send a message. Pick one and put it near the top of the caption and again at the end. Two or three options make people stall.

Keep Reviews Out of the Deal

Never tie a discount or gift to a 5-star review. The FTC's Consumer Review Rule bans incentives conditioned on positive reviews, and breaking it can bring civil penalties of up to $53,088 per violation. Asking every customer for an honest review is fine. Paying for a good one isn't.

Keeping the Mix Going in a Busy Month

The ratio is the easy part. The hard part is still posting in July when you're running calls until dark.

A few habits help.

• Take before and after photos on every job, even when you don't plan to post them.
• Pick one evening a week to schedule the next week's posts.
• Mark your offer weeks on the calendar at the start of each month, so they don't land back to back.
• Save every good review in one folder as it comes in.

If you'd rather not do the making and scheduling yourself, NanoFlow makes reels and carousels from your jobs, photos and reviews, and posts them after you approve each one. That keeps the useful and proof posts coming, and you decide when an offer goes out. Social Growth also turns new 5-star reviews into posts. You can see what each plan includes on the NanoFlow plans and pricing page.
