Most marketing budgets buy time, not assets. Paid search buys impressions until the budget line closes. A PR retainer buys this quarter's coverage. A content program buys rankings that hold only while someone keeps feeding the machine. Stop paying, and within months it is largely as if the spending never happened.
This article makes a narrower and more defensible claim than the "Wikipedia is free marketing" pitch you may have read elsewhere: measured over five years, a properly built and maintained Wikipedia page has one of the best durability-per-euro profiles of any marketing investment a company can make. We will do the math with real numbers — ours are published prices, the rest are clearly labeled ballparks — look at what the page actually does around the clock, and be blunt about the ways this investment fails. This piece argues for the asset class; for the line-item price breakdown, see How Much Does a Wikipedia Page Cost in 2026?
Three decay curves, one compounding curve
Almost everything in a marketing budget sits on a decay curve.
Paid media decays instantly. The day the campaign stops, the impressions stop. There is no residual. Five years of paid search leaves you with exactly as much standing visibility as zero years of paid search.
Content decays gradually. Blog posts and landing pages erode as competitors publish, algorithms shift, and information goes stale. A serious SEO program is partly new ground and partly re-fighting for ground already taken.
Press decays into archives. Earned coverage is real and valuable, but it ages out of news cycles within weeks. It does leave one durable residue, which matters later in this article: archived independent coverage is precisely the raw material Wikipedia eligibility is built on.
A maintained encyclopedia entry sits on a different curve. Wikipedia articles tend to accumulate standing rather than lose it: they collect internal links from related articles, they are crawled and cited constantly, and search engines have treated the domain as a top-tier reference for two decades. A page published in year one is usually stronger in year five — better linked, more complete, more entrenched in search results — provided it is sourced well enough to survive and watched well enough to stay accurate.
Two corrections to the popular version of this argument, because the overclaim is exactly where buyers get hurt:
- It is not a one-time cost. The "publish once, benefit forever" framing in most marketing blogs ignores the fact that anyone can edit a live page, facts go stale, and deletion can be proposed at any time. Durability is a property of a maintained page, which is why honest math includes annual support, not just creation.
- You do not own the page. It belongs to the encyclopedia and its volunteer community. Neutrality cuts both ways: well-sourced criticism can appear on it, and you cannot simply remove what you dislike. What you are buying is a defensible, accurate entry — not a brochure.
With those corrections on the table, the durability argument survives intact. Here is what it looks like in euros.
The five-year table
The comparison below puts a professionally created English company page (from €1,930) plus baseline annual support (from €420 per year) next to three channels a brand might fund instead.
| Channel | Typical spend pattern | Indicative 5-year outlay | What remains if you stop paying in year 3 |
|---|---|---|---|
| Paid search (brand + category terms) | Commonly €2,000–5,000 per month for a modest program, media plus management | €120,000–300,000 | Nothing. Visibility ends the day the budget does |
| PR retainer | Agency retainers commonly run €3,000–8,000 per month at the modest end | €180,000–480,000 | Archived coverage — fading from feeds, but it can later support Wikipedia eligibility |
| SEO content program | Commonly €1,500–5,000 per month for sustained output | €90,000–300,000 | A content library that decays as competitors publish and rankings erode |
| Wikipedia page + support | From €1,930 once, plus from €420 per year | From €4,030 | The page stays live and ranking — though now unwatched, which reintroduces drift and deletion risk |
Read the table with three caveats, because a comparison without caveats is an ad.
- The first three rows are order-of-magnitude ranges, drawn from commonly published agency rates and industry surveys, not quotes. Your market, sector, and ambition level can move them substantially. The Wikipedia row uses WikiBusines published prices.
- These channels do different jobs. Paid search generates demand this week; a Wikipedia page never will. The honest comparison is not "replace your ad budget" — it is that for the specific job of being credibly findable and verifiable, no other line item comes close on cost.
- €4,030 is the entry scenario — one English page on the baseline support tier. Add stronger monitoring, more language editions, or a complex review cycle, and a realistic five-year total for a well-maintained page lands between roughly €3,500 and €9,000, as broken down bucket by bucket in the cost guide. Even the top of that range is a rounding error against the other rows.
What the page does at 3 a.m.
Durability would not matter if the asset sat idle. A live Wikipedia page works continuously, in three rooms where you are almost never present.
Due diligence. Investors, journalists, enterprise procurement teams, and senior candidates routinely check Wikipedia early in their research — usually before they ever contact you. A neutral, well-sourced entry answers the quiet question "is this company real and established?" with third-party evidence rather than your own claims. No "About us" page can do that, because everyone knows who wrote the "About us" page.
Search and the Knowledge Panel. Wikipedia pages consistently rank on the first results page for the subject's name, and the Wikipedia–Wikidata pair is the most reliable known input for a branded Google Knowledge Panel — the fact box that anchors your name's search results with logo, founding date, and official website. That position is earned through notability, not bid on monthly.
AI answers. Wikipedia is consistently among the most heavily weighted and most-cited sources in large language models' training and retrieval. When someone asks ChatGPT, Gemini, or Perplexity about your company, a well-maintained article measurably raises the probability that the answer is accurate and grounded — though no one can promise a specific AI mention, and you should walk away from anyone who does. The full mechanism is mapped in Wikipedia, Wikidata, and AI Search.
All three run 24 hours a day, in every market, at no marginal cost per impression.
The risk column nobody prints
A five-year asset case is only honest if it includes the ways the asset can go to zero.
Deletion. If the independent coverage behind a page is thin, the page can be nominated and removed — and deletion is the most expensive outcome in this market, because you pay for the failed attempt, recovery costs more than first-time creation, and a prior deletion prejudices future tries. Weak sources do not make a cheaper page; they make a shorter-lived one. This is why the disciplined order of operations is audit first, build second: a Notability Audit (€490–1,900, credited toward the project if you proceed) prices the survival question before you fund the asset.
Drift. An unwatched page accumulates stale facts, errors, and occasionally hostile edits, and Wikipedia does not notify you when any of it happens. The €420-per-year baseline exists because the compounding curve assumes someone is watching.
No certainty. Wikipedia is governed by an independent volunteer community, and no provider controls its decisions. WikiBusines publishes a 93% success rate and an 80% refund if a published page cannot be defended after three attempts within the 90-day monitoring window — a priced risk, not a guarantee, because guarantees do not exist here.
When a Wikipedia page is a bad investment
Two situations, stated plainly.
You are not notable yet. If independent journalists, analysts, or authors have not written substantively about your company, no honest provider can build you a durable page — and a dishonest one will build you a deletion. The right move is the unglamorous one: earn real, independent coverage first. This is where the PR-retainer row earns its keep, because press is the raw material of eligibility. An audit that returns "not yet" plus a map of the source gap costs €490 and saves you the entire failed project. That is source readiness, and it is a legitimate answer.
You need pipeline this quarter. A Wikipedia page is a trust asset with a five-year payoff curve, not a demand-generation channel. If the business needs leads in ninety days, spend on the channels built for that, and revisit the durable layer when the horizon lengthens.
The math, restated
Over five years, the entry-level Wikipedia investment — from €1,930 in creation plus from €420 a year in support — totals about €4,030. The comparable channels cost roughly twenty to a hundred times more over the same window, and almost nothing they buy survives the final invoice. The page, if it is built on real sources and kept watched, is typically stronger in year five than in year one.
The only question worth settling before spending anything is whether your sources can carry the asset. That question has a fixed price and a clear answer either way: start with a Notability Audit, and fund the durable asset only when the answer is yes.
