The honest version
Why "best Facebook marketing company in BD" usually means one good operator, not a 30-person agency
Open Facebook right now and you'll see twenty Bangladeshi agencies promising "guaranteed leads", "viral campaigns", or "10x ROAS in 30 days". Then you sign up, pay 25,000 BDT a month, and the work goes to a fresh graduate who boosts your existing post, picks Bangladesh + 18-65 as the audience, and sends you a screenshot of "reach" at the end of the month. No pixel firing properly, no Conversions API, no UTM tracking, no idea which ad actually produced the bKash payments. That's not marketing. That's a monthly invoice with extra steps.
I run Facebook campaigns the way a serious in-house performance marketer would — except you don't pay a 1,20,000 BDT salary for it. Every account starts with proper Meta Pixel + Conversions API + offline conversions setup, a real audience research session in your category (D2C fashion in Dhaka behaves very differently from B2B services or real estate), and creative direction written for the way Bangladeshi buyers actually scroll on a Symphony or low-RAM Android phone at night.
Around five years of doing this for clients across Dhaka, Chattogram, Sylhet and abroad means I've already seen most of the patterns. I know which Lookalike sizes work for a 2,000-purchase pixel vs a fresh one, why your CPM doubles every Eid and Pohela Boishakh, when to push Advantage+ Shopping vs manual CBO, and how to keep a campaign alive when Meta randomly disables your ad account on a Friday night.
If you're searching "best Facebook marketing company BD", what you actually want is one experienced person who picks up the phone, understands your margins in taka, and treats your ad budget like it's their own. That's the offer.
