Start with good original photographs
A well-lit, sharp photograph gives you more options than heavy editing of a weak image. Check the colour and texture of the product: customers should see what they will receive. For services, show the real space, people and process with their permission.
Vary framing and details
Combine wider views, close-ups, scale and use. Avoid placing only similarly busy images in succession. Calmer compositions can make the feed easier to browse. Several useful views of one item can sit together in a carousel when they help someone evaluate it.
Agree on simple visual rules
Choose a limited set of colours, typefaces and cover treatments. Leave room for natural photographs: consistency does not require an identical frame on every post. Image text should be readable on a phone, with essential information also included in the caption.
Make each post work independently
A visitor may see a post in recommendations rather than in the profile grid. Do not rely on neighbouring images to explain its meaning. Check video covers and profile cropping so that the title and product remain clear.
Review the feed as a customer
Can you see the range, details and ways to use the product? Are categories easy to distinguish? Has editing hidden important properties? A tidy visual style does not guarantee sales: the profile also needs clear terms and an easy way to make an enquiry.
