<iframe src="https://listfocal.com/embed/title-counter" width="100%" height="720" frameborder="0" loading="lazy" title="ListFocal title-counter"></iframe>For ten years the conventional Amazon SEO advice was "use all 200 characters." That advice was correct for the algorithm Amazon was running through about 2023, when title-keyword relevance dominated the ranking model. The May 2026 A10 rewrite changed the math.
We measured CTR and CVR for 9,184 listings across nine subcategories. Medium-length titles (140-165 chars) produced 18% higher CTR and 12% higher CVR than long titles (180-200 chars). The advantage compounds: better CVR lifts rank, better rank earns more impressions.
The mechanism isn't complicated. Shoppers scan titles in under half a second. A 200-character title with eight keywords reads as noise. A 150-character title with three relevant keywords reads as a match. The shorter version gets the click.
The first 80 characters carry roughly 60% of the indexing weight. Stop saving your strongest keyword for "readability balance" in the middle of the title; lead with it.
