<b>One product in five categories — duplicate problem?</b>

'Q: My product appears under multiple categories. Is that creating duplicate content issues?'

<b>Short answer:</b> Only if each category generates a different URL for the same product. One canonical URL fixes it.

The longer version: showing a product in five category listings is normal merchandising and totally fine. The problem appears when your platform mints a unique product URL per category — <code>/sale/widget</code>, <code>/new/widget</code>, <code>/gifts/widget</code> — all the same product. Now you have five competing URLs splitting signals.

Fix: every product resolves to one canonical URL regardless of which category the user clicked from. The product page's <code>canonical</code> tag points to that single address; the rest either don't exist or canonical to it.

For breadcrumbs and structure, assign one primary category as the canonical path even though the product appears in several listings. That keeps your hierarchy clean and your relevance focused.

Rule of thumb: a product can live in many lists but must have exactly one address.
