Wikipedia is one of the most influential authority assets on the web. A Wikipedia entry acts on three layers simultaneously: a prominent spot on the brand SERP (usually page one in our analyses), a source for Google's Knowledge Graph, which Google launched in 2012 with Wikipedia data among others, and a fixed part of LLM training data. Brands that reach Wikipedia cleanly gain structural leverage. Those who try without notability burn time and risk COI flags that complicate any future Wiki work.

What notability criteria does a Wikipedia article have to meet?

A Wikipedia article needs notability that independent, reliable sources can document. On English Wikipedia, the General Notability Guideline presumes a topic notable when it has received significant coverage in reliable sources that are independent of the subject. Presumed means an assumption, not a guarantee: a discussion can still decide against a stand-alone article.

For companies, WP:NCORP requires multiple sources that are each significant, independent, reliable and secondary. It explicitly states that figures such as headcount, revenue or capital raised do not make coverage significant, and that press releases or directory listings do not count. German Wikipedia takes a different approach: its relevance criteria name hard thresholds for companies, such as at least 1,000 full-time employees, more than 100 million euros in annual revenue, a regulated-market listing or at least 20 sites for a large corporation. Anyone targeting both language versions has to meet both logics.

Our practical test question (a rule of thumb, not an official number): are there at least 8–15 independent, editorially vetted sources about the entity, distributed across several years? If not, build notability first (through trade-media work, industry publications, digital PR), then approach Wikipedia. Reversing the order often ends in a declined draft or a deletion discussion.

The six-month protocol

Months 1–2: notability audit. Collect every existing mention and assess it against Wikipedia criteria. Identify the gaps: which topics would benefit from additional independent coverage?

Months 2–4: build corroboration. Targeted digital PR in trade media, industry publications and academic outlets. No sponsored content, no press-release copies. Focus on editorial depth.

Months 4–5: article draft. Neutral, encyclopedic tone. Every substantive claim with a reference. Structure: lede, history, activity, reception. No marketing language, no superlatives.

Months 5–6: submission and review. Submit the draft through Articles for Creation, which editors with a conflict of interest must use, and disclose the COI on the draft's talk page. On German Wikipedia, drafts go on a personal subpage with feedback from mentors. After review: publish with a readiness for iterative editing.

Can you write a Wikipedia article about yourself or your company?

It is not forbidden, but Wikipedia's conflict-of-interest guideline strongly discourages editing articles about yourself or your company directly. Editors with a COI should disclose it, propose changes on the talk page through edit requests and create new articles through Articles for Creation rather than publishing them directly.

Paid editing is allowed only with disclosure. Under the paid-contribution disclosure policy and the Wikimedia Terms of Use, paid editors must name their employer, client and affiliation on their user page, the relevant talk page or in the edit summary. Editors who cannot disclose are not allowed to edit, and violations can lead to blocks. Paid editors should also not act as reviewers at Articles for Creation.

The professional approach: a draft with a clear self-declaration, review by experienced independent editors, and a move into the main namespace only after their approval. That is slower — and far more durable — than impatient direct edits.

Why Wikipedia matters more for GEO

LLMs weight Wikipedia disproportionately. This is documented for GPT-3: according to the OpenAI paper (Brown et al., 2020), 3% of the training mix came from English Wikipedia, which at about 3.4 passes was seen more often than any other source. Current providers mostly do not disclose their training data in detail. In our observation, a brand with a clean Wikipedia entry is rendered correctly far more often. Without solid sources, the risk of mix-ups rises: in our entity resolution pilot, only 18.5% of 54 AI answers about 18 people were error-free (own data). For entity SEO and knowledge panel work, Wikipedia is a strategic accelerator.

Conclusion: Wikipedia is authority, not marketing

Wikipedia is not a channel to be acquired — it is a kind of certification: those who meet the criteria have a good chance of getting the asset. Those who do not should build substance first, then approach Wikipedia. The most common mistake is the reverse path — pushing into Wikipedia without a notability base, with follow-on costs from deletion history and COI stigma. Deletion discussions (AfD) normally run for seven days, and recreating a page deleted after such a discussion can be speedily deleted under G4.
