Duplicate content

Also known as: duplicate pages · copied content

Definition

Duplicate content is substantially identical or very similar content that appears at more than one URL, on one site or across several. Search engines usually choose one version to show and fold the others away, which can leave an unintended page ranking.

Most duplication is accidental. Tracking parameters, sort and filter options, HTTP and HTTPS or www and non-www versions, print pages and session IDs all create extra addresses for one page. Manufacturer descriptions pasted by many retailers, and location pages with only the city name swapped, create duplication across and within sites. The usual cost is dilution: links and signals split between copies, and Google picks a version you didn't choose.

Search engines mostly handle ordinary duplication by choosing one version, not by punishing the site, which is why a duplicate content penalty is the wrong thing to fear. Deliberate copying at scale to manipulate results is a separate matter, covered by Google's spam policies. Fix accidental duplication with a canonical tag, a permanent redirect or noindex, and make internal links point to the preferred address.

An Arabic page and its English twin are not duplicates when each is written in its own language, and hreflang tells Google they belong together. A machine-translated mirror of an English page, published to fill out an Arabic section, is a different problem, closer to thin content than to duplication. For online stores, rewrite the manufacturer's description for your own customers, covering delivery, sizing and use in the UAE.

AEO (Answer Engine Optimisation)

AEO is the practice of structuring content and data so AI assistants such as ChatGPT, Perplexity and Google AI Overviews cite a business as a source when answering questions, including when no click follows.

AI citation

An AI citation is a reference to a source inside an AI-generated answer, usually a named link to the page the assistant drew on. A brand can also be mentioned without a link, and an answer can use a page without crediting it.

AI crawlers

AI crawlers are automated programs run by AI companies that fetch web pages, either to gather material for training models or to find content for an answer. Examples include OpenAI's GPTBot, Anthropic's ClaudeBot and Perplexity's PerplexityBot. Google-Extended is a robots.txt control rather than a separate crawler.

AI SEO

AI SEO is a label for two different jobs: getting a business cited or mentioned in answers from AI search tools, and using AI tools to do SEO work faster. Which one a speaker means decides what is actually being sold.

AI visibility

How often a brand is named or cited in answers from AI assistants for the prompts its buyers actually use. The emerging equivalent of rank tracking, measured by prompting at scale and counting mentions.

Alt text

Alt text is the written description in an image's alt attribute. Screen readers read it aloud for people who cannot see the image, browsers show it when the image fails to load, and search engines use it to understand what the image shows.
