How Often Should a Small Business Post? (Each Platform, With the Data)

The honest answer first

There's no one number that fits every platform.

Some platforms have real data on how often to post. Some don't. Below, each platform gets the number we recommend, and we tell you which part is a study and which part is our advice.

Instagram: 3 to 5 feed posts a week

This one has real data.

Buffer studied 2.1 million posts from 102,000 Instagram accounts. Posting 3 to 5 times a week "can more than double follower growth rate, compared to posting one or two times weekly", and reach per post rose about 12%. (Buffer, August 2025)

Posting more kept helping, but each extra post bought less. In Buffer's words, "the returns are diminishing."

The one thing that clearly hurt: weeks with zero posts. Those weeks pulled accounts below their own normal growth.

So you don't need to post twice a day. You need to never go quiet.

Our mix for a week: about 2 Reels, 1 or 2 carousels and 1 photo, plus Stories when something happens.

Facebook: 3 to 5 posts a week

No large study prescribes a number for Facebook. 3 to 5 a week is our recommendation, so your Facebook can share the work you already made for Instagram.

What the data does say is what to post:

• Link posts came last. Socialinsider measured 0.05% engagement for link posts against 0.20% for plain text. (Socialinsider)
• 98.7% of what people saw in their US Feed had no link to an outside site. (Meta, Widely Viewed Content Report, Q1 2026)

So post photos, short videos and plain posts. If you need a link, put it in the first comment.

LinkedIn: 2 to 4 posts a week, from your own profile

Buffer studied over 2 million LinkedIn posts from 94,000+ accounts. Each step up in how often people posted added impressions per post, and Buffer's suggested range for steady growth is 2 to 5 posts a week. (Buffer, August 2025)

Spacing matters too. In Ordinal's data, posts published within 12 hours of each other got 17% lower engagement. (Ordinal)

Our call: 2 to 4 a week, about a day apart. That's a pace a business owner can keep while doing the actual work.

And post as yourself. Metricool's 2026 study of 673,658 posts found personal profiles had a 63% higher engagement rate than company pages, with similar reach. (Metricool)

Google Business Profile: one update every two weeks, one offer always live

Here's the surprise: there's no evidence that posting more on your Google profile moves your Maps ranking.

• Google's page on local ranking doesn't list posts. (Google)
• A 2021 test posted weekly to 3 listings for 9 weeks and found "no measurable impact on rankings in the local pack." (Sterling Sky)
• 47 local search experts ranked post frequency #148 of 187 factors for Maps ranking. (Whitespark, 2026)

Posts still help. They help the person who already found you decide to call. In one study of about 1,000 posts, offer posts averaged 3.06 clicks as reported by Google, against 0.76 for plain updates. That data is from 2020 to 2021. (Sterling Sky)

And posts stay up for six months before they're archived. (Google)

Our call: one update every two weeks, and one offer always live, each with a photo you took. Spend the time you save asking for reviews. Google's ranking page does name those: "More reviews and positive ratings can help your business's local ranking."

What about the best time to post?

Don't lose sleep over it. The big studies don't even agree:

• Buffer's 9.6 million Instagram posts point to Thursday at 9am. (Buffer)
• Later's 6 million point to 5am. (Later)

Buffer says "content quality still matters most." Later says "consistency matters more than perfection."

Pick a time you can keep.

The real problem isn't the number

It's keeping it up. HubSpot surveyed over 1,100 social media marketers, and 45% said consistently producing high-quality content is their top challenge. (HubSpot 2026 Social Media Marketing Report)

That's why we plan the whole month in one sitting, then spend a few minutes a day on the part that can't wait. Give it about three months before you judge it. That's our advice, not a study.
