People stop scrolling for an ad when, at a glance, they see something that clearly concerns them: a product they recognise, a face, a situation they know, or an answer to a question they have had. Good ad design makes that one thing obvious on a small phone screen. In practice that means one clear focal point, strong contrast, very little text, real products and people, and, for video, an opening that works in the first moment without sound.

Design for the phone first

Most people will see your ad on a phone, often a mid-range one, sometimes in bright sunlight, often on a slow connection. Design for that, not for your laptop screen.

  • Use shapes that phones show well. Square and vertical formats take up more of the screen than wide ones. Placements such as Stories and Reels crop differently, so check each preview in Ads Manager.
  • Keep the edges clear. Platform buttons, captions and profile names sit over parts of vertical ads. Keep faces, products and text away from the very top and bottom.
  • Check it on a real phone. Send the design to your own phone and look at it at arm's length. If you have to squint, the text is too small.
  • Mind the file size. Many people browse on limited mobile data. A heavy, slow-loading video may be scrolled past before it even plays.

Principles for images

One clear focal point

Every image needs one thing the eye lands on first: the product, a face or a short headline. If everything is equally loud, nothing stands out. Remove anything that doesn't help.

Real products, real context

A generic stock photo looks like every other ad. Show your actual product, in use if possible: the saree being worn, the cake on a birthday table, the water pump fitted in a real house. Hands and faces attract attention, and they help people judge size and quality.

Contrast that stands out in the feed

The feed is full of white backgrounds, grey interfaces and busy photos. An image with clear contrast between the subject and the background, and a colour that is recognisably yours, is easier to notice. Stay consistent with your brand colours so people start to recognise you.

Few words, large and readable

Text on an image should be a headline, not a paragraph: what it is, and perhaps the offer. Price lists and long descriptions belong in the ad text or on the landing page. For Bangla, choose a font that renders conjuncts and vowel signs correctly, because broken Bangla text looks careless. Bangla web typography covers the basics.

Principles for video

Win the first moment

Don't open with a slow logo animation. Open with the product, a face or the problem, so that someone who sees only the first second knows what the ad is about.

Design for sound off

Many people watch with the sound off: on a bus, in an office or late at night. Add captions in your buyers' language, and put the key message on screen as text.

Show, then tell

Movement catches the eye, but it should mean something: the product being used, an honest before-and-after where platform rules allow it, or the steps of a process. Keep shots short and easy to follow rather than frantic.

Brand early, ask clearly

Show your name or logo early enough that viewers who leave halfway still remember it, and end with one clear call to action. For a routine a small team can sustain, see Reels and short videos without a production team.

Mistakes that make people scroll past

  • Images crowded with text, logos, stickers and prices all at once.
  • Pictures that make the product look better than what arrives, which leads to returns. The copy and the creative must make the same honest promise; see writing ad copy that sells honestly.
  • Running the same creative for months until everyone has seen it too often. A simple creative testing system keeps fresh options ready.
  • Designs that only work with sound, or only on a big screen.

A checklist before you upload

  • Can you tell what is on offer in one glance at arm's length?
  • Is there one focal point, with strong contrast?
  • Is any text short, large and spelled correctly, in Bangla or English?
  • Does the video make sense in the first second, and without sound?
  • Are faces, products and text clear of the edges in vertical placements?
  • Does the creative show the real product honestly?

Make two or three versions that differ in one thing only, such as the opening shot or the headline, and let the results tell you which works. If you'd like help with creatives and campaigns, see my social media and ads management service.
