By Industry
Generic advice breaks down fastest at the point where an industry has rules. A dentist cannot show a patient, a law firm cannot imply a result, and a restaurant posting three times a week has a completely different content supply than an accountant does. Each of these takes one trade and covers what there is to post, what the regulator or the platform stops you posting, and which formats earn their place for that specific business.
All 9 guides

Social media for veterinarians: the best material in medicine, and the comment you cannot answer
A veterinary practice has the most engaging content of any healthcare business and the tightest rule about replying to it. What to post from the consult room, why answering is my dog alright in a comment is a legal problem and not just a busy one, what a client's animal and a client's grief actually belong to, and how to say no in a way that books an appointment.

Social media for gyms: the before and after post, and what has to be true about it
The transformation photo is the highest performing and highest risk post in the industry, and the rule about it is not the one most gyms think. What to post to fill a class, what the FTC requires next to an atypical result, what you cannot say a workout does, and the member in the background who never agreed to any of it.

Social media for real estate agents: what you can say about a house, and what you cannot
The word list every agent has been shown came from a HUD memo that was withdrawn thirty years ago. The rule that replaced it is shorter and harder. What to post, the licence line that belongs in the caption, why boosting a listing is a different act from posting one, and the six posts that get a listing appointment.

Social media for construction companies: the progress post, the finished post and the site rules
A build takes months and produces a photograph every day, which makes construction the easiest trade to post for and the one that posts least. The progress post, the finished post, the crew post, the licence number that has to be in the caption, the client's address that must not be, and the drone shot everyone makes that gets nothing.

Social media for plumbers: what to post between emergencies
A plumber's customer is not scrolling; they are standing in water. What social media actually does for a trade whose work arrives by phone, the six posts that make the phone ring, the licence number that has to be in the post, and the van photograph everyone makes that does nothing.

Social media for restaurants: the six posts that fill tables, and the six that fill a feed
Restaurants have the easiest material on social media and post the least of it. What to post from the pass, the floor and the book, what needs a diner's permission, what a free meal to a reviewer legally is, and why the reel of the pour is not the post that fills a Tuesday.

Social media for dentists: what you can show, and what HIPAA stops
Dental marketing runs on before and after photographs, which are also the single easiest way to breach a patient's privacy. What needs written authorization, what does not, and the posts that fill the gap.

Social media for law firms: the rules, and what to post inside them
The advertising rules for lawyers are stricter than for almost any other business, and they are also narrower than most firms assume. What Rule 7.1 and 7.3 actually say, and the posts that fit comfortably inside them.

Social media for accountants: what you can post, and what you cannot
Accounting is one of the few businesses where the content already exists and the rules are strict. The year's calendar, the five posts that actually bring in work, and the lines Circular 230 draws around all of it.
