The advice to pick one platform is easy to give and hard to follow, because it leaves out how to pick. I am going to lay out a way to decide, using published audience data and the guidance of a small business development center, and I am going to stop short of telling you which platform I would choose for the Heritage Diner. Nothing in this post should be read as a hint toward one, and the framework works without it.

Choosing the RIGHT Social Media Platforms for your Business – Explained, Mighty Sites on YouTube

Why one

A small business has a fixed amount of someone’s evenings. In 2008 and 2009 I was an adjunct lecturer at Queensborough Community College, teaching an introductory information systems and technologies course, and I steered it toward new media in small business, which was my own choice of direction. The platforms from that time are mostly gone or unrecognizable. The question underneath that course has not changed: where do I spend the hours.

The Rhode Island Small Business Development Center, part of the University of Rhode Island, puts the answer in one line in its June 2025 article, Which Social Media Platform Is Right for My Business?: “Focus your efforts on one or two platforms that align best with your goals.” The article’s reasoning is that success is about being strategic, not about being everywhere. Its list of questions is the backbone of what follows, and I have added the audience numbers on top of it.

Where the customers are

Start with who is on which platform, because a post nobody reads costs the same hours as one everybody reads. The best public dataset I found is the Pew Research Center’s Americans’ Social Media Use 2025, published November 20, 2025. Its usage figures come from a survey of 5,022 U.S. adults fielded February 5 to June 18, 2025, and a separate survey of 5,123 adults, fielded February 24 to March 2, 2025, covers how often people visit.

In Pew’s words, “The vast majority of U.S. adults (84%) say they ever use YouTube.” The article says Snapchat and X are used by somewhat fewer adults than WhatsApp, without giving exact figures in the text I read, and I did not find LinkedIn or Pinterest in it.

These are shares of all American adults. They are not shares of your customers, and they say nothing about which platform sells anything. A platform can have most of the country on it and none of your town. So the next step is breaking the numbers down by age, which Pew does for some platforms.

What age does to the picture

Pew reports that eight in ten adults aged 18 to 29 use Instagram, against 19 percent of adults 65 and older. TikTok shows the same gap in daily use: roughly half of 18- to 29-year-olds use it daily, compared with five percent of those 65 and older. YouTube and Facebook are the only two platforms a majority of adults use in every age group, and Facebook use peaks among 30- to 49-year-olds at 80 percent.

If the customers you want are mostly in one age band, those splits are worth more than the headline totals. A shop selling to people in their twenties and a business serving people in their seventies should not read the same table the same way. That sentence is a reading of the data, not something Pew says.

The URI article gives a different set of audience descriptions, and they do not match Pew everywhere. It calls YouTube’s audience mainly ages 18 to 49 and skewing male, Facebook adults 30 and over and strong for local and community outreach, LinkedIn professionals mostly 25 to 54, Instagram mainly 18 to 34, and TikTok mainly Gen Z and Millennials. Pew says a majority of adults in every age group use YouTube. The two are describing different things, since one counts who ever uses a platform and the other describes who a business is likely to reach, and the article does not say where its descriptions come from. I would give Pew’s survey the heavier weight and URI’s descriptions the lighter one, and I would notice that they disagree before leaning on either.

What you can make, week after week

The second question in the URI article is the one that sinks most plans: “what type of content can you realistically produce on a regular basis?” The article attaches a content type and a cost to each platform.

  • YouTube wants long-form video, typically five minutes or more, with strong titles and thumbnails, and the article says it takes longer to build subscribers.
  • TikTok wants short, often informal video of 15 to 60 seconds. Both video platforms, the article says, take more production effort.
  • Instagram wants high-quality photos, Reels, Stories and branded graphics, and the article notes growth can be slow without steady effort.
  • Facebook takes photos, short video, text updates and event listings. The article says organic reach there is limited, so paid promotion is often needed.
  • LinkedIn takes full articles, professional updates, company news and business insights.

The article also says that if video is hard for you, LinkedIn or Facebook may be more manageable. Read that as a warning against picking the platform where your customers are and then discovering you cannot make the thing it rewards. A video platform with no one willing to be on camera is a dead channel with a login.

Goals, and the reason to say them out loud

The third question is what you are trying to get. The URI article offers three examples: driving website traffic, building brand awareness, and generating leads. Those are not the same job. A restaurant that wants people to find the hours, the menu and the address has a different goal than a business that wants strangers to learn its name, and platforms that suit one do not always suit the other.

Write the goal as a sentence with a verb in it before opening any app. “Get the menu in front of people who live within a short drive” is a goal. “Be on social media” is a calendar entry. If you cannot finish the sentence, no platform will do it for you.

Putting the three questions together

Here is the whole method, in order, using only what the sources support.

  • Name the goal in one sentence.
  • Name the customers you want and their rough age. Check that group against Pew’s age breakdowns for the platforms you are considering.
  • Name the kind of content you can make every week for a year, not the kind you can make for a month. Match it against the content types the URI article lists.
  • Pick the platform where those three overlap. If two qualify, pick the one where you already have material.
  • Do that one for a stretch, then decide whether to add another. The URI article says to expand once you have momentum.

There is a real argument against all this, and I should say it. Choosing one platform means betting that your customers live there, and a bet on one place can miss. Pew’s own numbers show most adults use more than one platform, since the shares in the table add up to far more than one hundred percent. A person who sees you on one will probably be elsewhere too. Pew does not say what happens if you skip the others, and I did not find a source that does.

Which one I would pick

I am not telling you which platform I would pick for the diner. I have not shared that, and publishing a pick would turn a framework into an endorsement. If you work through the steps above with your own goal, your own customers and your own hours, you will get an answer that fits your counter, not mine.

The first post on this site, What Till Post Is For, explains why a post like this one ends where it does. Where I have not done the thing myself, I say so, and where I have, I tell you how.

For informational purposes only; audience figures describe the U.S. adult population in a 2025 survey, not your customers, so check them against your own.
