Preview: your title on mobile
Type a title and watch where Amazon's app cuts it off, around 80 characters. This preview only shows your title length and the mobile cutoff. It does not render your full listing, score it, or check it. That is the Amazon FBA Listing Optimizer.
π‘ Quick answer: A strong Amazon title follows a clear order, Brand + Main Keyword + Key Feature + Size + Color, stays within the 200-character limit (some categories cap at 80 or 150), and front-loads the most important words, because Amazon's app cuts titles off around 80 characters on mobile, where most shoppers are. No all-caps, no promotional claims, no symbols.
Why your title matters more than anything else
Your title does two jobs at once, and both decide whether you make the sale. It is the strongest signal Amazon uses to match your product to a search, so a weak title means you never show up. And it is the first thing a shopper reads, so a confusing title means they scroll past even when you do show up. Get the title wrong and nothing else on the listing gets a chance.
The title formula
The reliable structure that ranks and reads well is:
Brand + Main Keyword + Key Feature + Size or Count + Color or Style
For example: "ACME Stainless Steel Water Bottle, Insulated, Leakproof, 32oz, Matte Black." The brand builds recognition, the main keyword gets you found, and the features and specs help the right shopper self-select. Lead with what buyers actually search for, not with clever marketing language.
The character limits
Most categories allow up to 200 characters in the title, but some cap at 150 or even 80. Always check your category, because a title that runs too long can get truncated or suppressed. Longer is not automatically better either. Cramming every keyword in makes the title unreadable and can look like stuffing.
The mobile cutoff nobody plans for
Here is the part most sellers miss. The desktop site shows your full title, but the Amazon app, where the majority of shoppers now buy, cuts it off around 80 characters. Everything past that point is hidden unless someone taps to expand, which almost nobody does. If your brand and main keyword are not in the first 80 characters, mobile shoppers never see them. The preview above shows exactly where that cutoff lands, so front-load your most important words before it.
What to avoid
Skip all-capital titles, since Amazon discourages them and they can trigger suppression. Avoid symbols and emoji like registered marks, trademarks, and decorative characters. Do not use promotional claims like "best seller" or "#1," which are banned. And resist stuffing the same keyword repeatedly, because it reads badly and Amazon can bury an over-optimized title.
