From the XBD team: XBD (Xplore Brand Differently) is a digital growth agency in Dhaka working on SEO, websites, social media, design, branding and video for brands in Bangladesh, the UK and the USA. This guide is based on how we work with clients day to day. Last reviewed: October 2026.

Most small businesses post on social media when they remember, get a few likes and wonder why nothing happens. The ones that win do something simple: they decide who they are talking to, post useful things on a rhythm, reply to people, and measure leads, not likes. This 90-day plan gives you that structure.

90-day social media plan in three phases: foundation, momentum and optimise
Three phases over twelve weeks: build the base, create momentum, then optimise.

Step 1: Decide what social media is for

Pick one primary goal for the next 90 days:

Goal Measure
Get enquiries or bookings Messages, calls, form fills from social
Sell products Orders and revenue from social links
Build awareness locally Reach, saves, follows from your area
Hire or recruit Applications and profile visits

Everything else (followers, likes) is a signal, not the goal.

Step 2: Know the audience

  • Who buys from you? Age, location, job, what they worry about.
  • What questions do they ask before buying? Each is a post.
  • Which platform do they actually use? In Bangladesh, Facebook, Messenger and WhatsApp dominate consumer business; Instagram and TikTok reach younger buyers; LinkedIn suits B2B and services; YouTube suits how-to and trust-building.

Step 3: Choose two platforms, not six

Platform Best for Content that works
Facebook Local customers, retail, services, community Photos, short videos, offers, customer stories, Messenger enquiries
Instagram Visual products, lifestyle, food, fashion, design Reels, carousels, stories, behind the scenes
LinkedIn B2B, consulting, hiring, professional services Insights, case studies, expertise posts
YouTube Education, demonstrations, long-term trust How-to videos, shorts, explainers
TikTok Reach among younger audiences Short, authentic video

Two platforms done consistently beat six done occasionally.

Step 4: Build 3 to 5 content pillars

Content pillars keep you from running out of ideas. For example, for a clinic or service business:

  1. Educate: answers to the questions customers ask.
  2. Prove: results, case studies, reviews, before and after.
  3. Show people: the team, the process, behind the scenes.
  4. Offer: a service, discount or booking prompt.
  5. Engage: questions, polls, local news and seasonal moments.

A balanced week might be three educational or proof posts, one team or process post and one offer.

Step 5: Use formats that fit the platform

  • Short video (reels, shorts): the strongest reach on most platforms. Open with the point in the first seconds and add captions, since many people watch muted. See our guide to video editing for business.
  • Carousels: great for step-by-step tips and checklists; design them clean and readable on a phone.
  • Single images and quotes: keep them on brand and uncluttered.
  • Stories: informal updates and polls.

Step 6: Create a simple calendar

A realistic starting rhythm for a small team is three to five posts a week on your main platform and one to three on the second. Batch the work:

  1. One session each month to plan topics and write captions.
  2. One session each fortnight to shoot and design.
  3. Schedule posts with Meta Business Suite or your platform’s scheduler.
  4. Reserve 10 to 15 minutes daily to reply to comments and messages.

Step 7: Engage and convert

  • Reply fast, especially to messages: speed is a sales advantage. Consider an auto-greeting and saved replies; for higher volume, a chatbot with human handoff.
  • Make the next step obvious: a link in bio, a WhatsApp button, a booking page.
  • Collect proof: ask customers for reviews and permission to share their story.
  • Track enquiries by source with a simple spreadsheet or UTM links.

Organic reach is limited, and a small paid budget can multiply what already works. Do not boost everything. Promote the 10 to 20 percent of posts that organically perform best, target a defined local audience and a clear goal (messages, leads, traffic), and review results weekly. Follow each platform’s advertising policies, and see Meta’s Business Help Center for setup guidance.

Step 9: Measure what matters

Level Metrics Why
Business Enquiries, bookings, sales from social, cost per lead The actual goal
Engagement Saves, shares, comments, replies Which content resonates
Reach Reach, impressions, video views, profile visits Whether people see you
Growth Followers from your target area Audience quality

At the end of each month, list your top three and bottom three posts, find the pattern, and make more of the first.

Mistakes to avoid

  • Posting only promotions.
  • Buying followers or engagement. It hurts reach and trust.
  • Ignoring comments and messages.
  • Copying competitors or trends that do not fit your brand.
  • Giving up after three weeks.

Frequently asked questions

How often should a small business post?

Consistency matters more than volume. Three to five good posts a week on your main platform is a sustainable target for most.

Which platform is best for my business?

The one where your customers already spend time and where you can show your product or expertise well. For many local businesses in Bangladesh that is Facebook first.

Do I need to run ads?

Not at the start. Build content and an audience first, then boost the posts that work.

How long until I see results?

Engagement can improve within weeks; consistent enquiries typically build over two to three months of regular work.

Can I hire someone to manage it?

Yes. Make sure they report on leads and sales, not just likes, and that you keep access to your own accounts.
