The Do's and Don'ts of Instagram for Small Business Owners

Instagram passed 3 billion monthly users in September 2025, according to Meta CEO Mark Zuckerberg. Closer to home, Pew Research’s 2025 survey found that half of US adults use it. People discover businesses there, check out your work before they call you, and send DMs instead of filling out forms.

For a small business owner, that can make Instagram a great marketing tool. It can also turn into a time sink that produces nothing.

The difference comes down to how you use it. Instagram has changed a lot recently: longer Reels, a taller profile grid, a hashtag cap, posts showing up in Google. So here are the do’s and don’ts that actually matter for small business Instagram right now.

The Do’s

Do: Decide what Instagram is for before you post

Why is your business on Instagram? To get DMs from potential customers? Show off your work? Send people to your website? Stay top of mind with past customers?

Your answer shapes everything: what you post, how often, and what success looks like. Without a clear purpose, you’ll post randomly and wonder why nothing’s working.

Do: Make every post for your customer, not for you

Every piece of content should be made with your ideal customer in mind. What do they want to see? What problems do they have? What questions do they ask you over and over?

Stop thinking about what you want to say. Start thinking about what they’d stop scrolling for.

Do: Post consistently

Consistency beats frequency. Posting three times a week, every week, beats posting daily for a month and then disappearing.

Pick a realistic schedule and stick to it. If you can only manage twice a week, that’s fine. Just be consistent. A simple content calendar makes that a lot easier.

Do: Make Reels part of your mix

Instagram leans hard into video, and Reels are the format it shows most to people who don’t follow you yet. We won’t promise a specific reach boost (that varies a lot by account), but if you want new local eyes on your business, Reels are your best shot.

A few things to know:

• Reels can run up to three minutes (Instagram raised the cap from 90 seconds in January 2025). Short still works best for most tips and before-and-afters, so only go long when the content earns it.
• You don’t need to be a video pro. Simple, real content often beats polished ads. Our guide to short-form video for camera-shy business owners shows you how to start, even if you’d rather not show your face.
• Instagram’s free Edits app is built for making Reels on your phone, with captions, trimming, and templates, so you don’t need to learn complicated software.

Do: Try Trial Reels when you’re testing something new

Not sure a new kind of video will land? Trial Reels let you show a Reel to non-followers first. Instagram gives you the results after about a day, and then you decide whether to share it with your followers. If it flops, your followers never see it. It’s a low-risk way to experiment, if your professional account has the option.

Do: Write captions people would actually search for

Since July 2025, public posts from Instagram professional accounts (business and creator accounts) can show up in Google and Bing search results unless you turn that setting off. That changes how you should write captions.

A caption like “Another one done!” tells Google nothing. A caption like “Kitchen cabinet refinishing in a Fountain City home: before and after, white oak to sage green” tells both Google and Instagram’s own search exactly what the post is about.

You don’t have to write essays. Just say what’s in the post, what you did, and where, in plain words a customer would use. Clear, descriptive posts also give AI tools something accurate to pull from when they describe your business. (More on that in our AI search guide.)

Do: Use Stories for the everyday stuff

Stories feel more personal and immediate than feed posts, and they’re perfect for things that don’t need to live forever on your profile.

Use Stories to:

• Show behind-the-scenes moments
• Share quick tips
• Run polls and question stickers
• Share customer shout-outs (with permission)
• Point people to your newest feed post or Reel

Save your best Stories to Highlights on your profile (think “Reviews,” “Pricing,” “Our Work”) so new visitors can find them.

Do: Engage with your community

Instagram is social. That means:

• Respond to every comment on your posts
• Reply to DMs promptly
• Comment on posts from customers and other local businesses
• Share customer content (with permission)

Conversation tends to lead to more conversation, and it’s how followers turn into customers.

Do: Tag your location

For local businesses, this is easy and worth doing. Tag your location (or the neighborhood where you did the job) on posts and Reels. It helps local people find you when they browse places on Instagram.

Do: Design for the new profile grid

In January 2025 Instagram switched profile grids from squares to taller rectangles. If you post images, a vertical 4:5 or 3:4 shape looks best in the grid. Old square posts get cropped on the sides, so check how your top rows look and adjust cover images if anything important got chopped off.

Do: Have a clear call to action

Every post should have a purpose. What do you want people to do after seeing it? DM you? Book online? Visit your website? Say so, plainly.

Do: Track what works

Instagram’s built-in Insights (available on professional accounts) show you what’s performing. Pay attention to:

• Which posts get saves, shares, and DMs, not just likes
• How many of your viewers are non-followers
• When your audience is most active
• Which content types do best for you

Do more of what works.

The Don’ts

Don’t: Make every post a sales pitch

The quickest way to kill interest is to make every post about selling. A common rule of thumb is roughly 80% value and 20% promotion. It’s not a law, just a good gut check.

Value means: tips, behind-the-scenes, before-and-afters, answers to common questions. Promotion means: buy this, hire us, sale this weekend.

Don’t: Stuff in hashtags (you only get five now)

Instagram began capping posts and Reels at five hashtags in December 2025, down from 30. So the old “wall of hashtags” approach is gone anyway.

Use specific, relevant tags. Generic ones like #love or #instagood won’t help your business. For a hypothetical Knoxville bakery, five solid choices might be: #knoxvillebakery #knoxvillefood #knoxvilletn #easttnfood #knoxvilleeats

Honestly, your caption matters more than your hashtags now. A clear caption helps with Instagram search and Google search; hashtags are just a small assist.

Don’t: Buy followers

It’s tempting, but fake followers hurt your account. They don’t engage, which makes your real content look less interesting to Instagram, and they never become customers.

Plus, it’s obvious. An account with 10,000 followers and 15 likes per post looks worse than an account with 500 followers and 50 likes.

Don’t: Ignore DMs

Direct messages are where conversations turn into jobs. Treat a DM like a customer walking through your door: respond promptly and helpfully. If you can’t answer during the day, set up saved replies or an away message so people know when to expect you.

Don’t: Post poor-quality photos

Instagram is a visual platform. Blurry photos, bad lighting, and cluttered backgrounds make your business look careless.

You don’t need a professional photographer. A recent smartphone, a window for light, and a clean background are enough. Just take an extra minute to make it look good.

Don’t: Copy what big brands do

National brands have different goals, budgets, and audiences than local small businesses. What works for Nike won’t work for a Knoxville boutique.

Focus on what makes you different: local knowledge, personal relationships, the people behind the work. If you’re not sure what that is yet, start with your brand positioning.

Don’t: Neglect your bio

Your bio is often the first thing potential customers see, and since profiles can show up in search, it matters even more. It should clearly say:

• What you do
• Where you do it (say “Knoxville” in plain words)
• How to contact you or take the next step

Use your link wisely. Send people somewhere that continues the conversation, like your contact page or booking page.

Don’t: Post and ghost

Posting and walking away is half the job. The real relationship-building happens in the comments and DMs afterward. You don’t need to sit glued to your phone, but check back that day and reply to everyone who took the time to comment.

Don’t: Expect overnight results

Instagram is a long game. It takes time to build an audience, find your content style, and see real business results. Think in months, not weeks, and judge progress by DMs and inquiries, not likes.

Is Instagram Right for Your Business?

Instagram is worth it if your business is visual and you can post consistently. It’s a weaker fit if your customers skew older or your work doesn’t photograph well.

According to Pew Research’s 2025 survey, about 80% of US adults ages 18 to 29 use Instagram, compared with 19% of those 65 and older. So it works best for:

• Visual businesses (restaurants, retail, salons, fitness, contractors with impressive work)
• Businesses whose customers skew younger than retirement age
• Businesses that can commit to consistent content

It might not be worth it for:

• B2B services whose buyers live on LinkedIn instead
• Businesses with nothing visual to show
• Businesses that can’t commit to regular posting

How Do You Get Started on Instagram for Business?

Switch to a free professional account, fix your bio, and post a handful of solid pieces before you promote your profile. Then pick a schedule you can keep.

1. Switch to a professional (business) account. It’s free and unlocks Insights.
2. Write a clear bio that says what you do and that you’re in Knoxville.
3. Plan your first six to nine posts so your grid looks complete when people visit.
4. Commit to a realistic posting schedule, with at least one Reel a week if you can.
5. Spend a few minutes a day replying and engaging with local accounts.

Start simple, stay consistent, and adjust based on what works. For the bigger picture, check out our free social media marketing guide or our post on growing your business with local social media. And if you’d rather hand Instagram off entirely, that’s what our social media marketing service is for.
