Wikidata is still a relatively little-known tool, but it is central to the semantic web ecosystem. This open database feeds Google, Bing, ChatGPT and Perplexity, among others, directly influencing your online visibility. Unlike Wikipedia, it allows the creation of entries for less publicized entities, offering an accessible SEO lever.
Key takeaways:
- Wikidata is a freely accessible and editable structured database used by Wikipedia, Google, Bing, ChatGPT, Perplexity, etc.
- Unlike Wikipedia, Wikidata accepts entries on less-publicized entities: useful for businesses, executives, institutions, brands and media.
- Properly used, a Wikidata entry improves your visibility, organic search ranking (SEO) and indexing in LLMs.
Wikidata vs Wikipedia: what are the differences?
You know Wikipedia: it's an encyclopedia made up of articles written in text. Wikidata, by contrast, hosts a structured database, designed to be read by machines... and used by them.
Wikidata has existed since 2012. The site powers the information boxes on Wikipedia (infoboxes), Google’s Knowledge Panels, and even AIs like ChatGPT or Perplexity.
And good news: you can have a Wikidata entry even without a Wikipedia page. Wikidata works on the same principle as Wikipedia: anyone can create or edit entries, provided they follow the contribution rules.
Why should professionals care?
Wikidata lets you be more visible on Google, Bing, ChatGPT, Perplexity and other important tools today. It's a concrete lever to strengthen your SEO and your GEO, indexing in generative AI search engines.
And this is not new : as early as 2016, an article in Search Engine Land already highlighted the central role of Wikidata in semantic SEO, as a database that feeds Google’s Knowledge Graph and allows queries like “George Clooney’s wife” to get a direct answer without clicking a link.
But with with the recent rise of generative AIs and conversational search, Wikidata is back in force. Its structured data allows AIs to understand entities (you, your business, your products) and to generate reliable answers.
And as a bonus, you contribute to a free, accessible, multilingual digital common good.
Researchers tested Wikidata's impact on content visibility through a project at the London School of Economics (source). By integrating their theses into Wikidata (without touching Wikipedia), they observed a 47% increase in downloads in six months and a doubling of traffic from Wikipedia to their archives.
Being present in Wikidata increases your chances of appearing or being cited on Wikipedia, even if you are not eligible on Wikipedia.
Are you eligible for Wikidata?
Unlike Wikipedia, Wikidata accepts less publicized entities. But not everything can be included there either: certain criteria must be met.
Good news: in 30 seconds, you can find out if you are eligible. Simply answer the questions below to test your situation, or that of a client.
