Listing & video SEO
Marketplace Listing and Product Video SEO: Titles, Bullets, Tags and Captions（繁體中文實戰指南）
A good product image or video still has to be found. Marketplaces rank listing titles and bullets; YouTube ranks titles, descriptions and tags; TikTok and Instagram rank captions. None of those fields are filled by the model that made the picture. This guide covers the copy that goes around your product media.
Marketplace listing copy
- Amazon title: commonly capped at 200 characters (many categories now recommend shorter). Order: brand, product type, key feature, size or quantity, colour. Put the main search phrase in the first 80 characters, which is what mobile shows.
- Amazon bullets: five bullets, one benefit each, leading with the benefit, then the proof (material, dimension, certification).
- Shopify: the product title becomes the H1 and default page title; keep the SEO title under about 60 characters and the meta description under about 155.
- Taobao / Tmall: titles up to 30 Chinese characters (60 bytes) — dense with attribute words buyers search.
Product video copy
- YouTube title — 100 characters. Put the search phrase first ("cordless vacuum for pet hair"), then the hook.
- YouTube description — 5,000 characters; the first 150 or so show above the fold. That opening paragraph is your SEO copy.
- YouTube tags — 500 characters total. Specific phrases beat generic ones.
- TikTok / Instagram — caption-first. One clear line, three to five relevant hashtags, product keyword in the text.
What makes generated copy underperform
Generic phrases ("premium quality", "game changer", "elevate your routine") match nobody's search and read as filler. Write from the product: what it is, who it is for, the measurable detail, the phrase a buyer would type. Do not make claims you cannot support — marketplaces remove listings for unsupported claims.
Order of work
- Create the clip on product video.
- Make a thumbnail still with first frames or in Marketing Studio.
- Paste product facts and the target keyword into listing and video SEO copy to draft the title, description, tags and captions within each platform's limits.
The tool writes within limits; it does not invent search-volume numbers. For keyword volume, use your marketplace's own search-term reports.
