Wikipedia Revenue Analysis: How a Wiki Could Make $2.3B a Year

Wikipedia is one of the largest websites in the world, attracting hundreds of millions of unique visitors each month and adding hundreds of articles daily. It’s also known for being a non-profit organization; the founders of the Wikimedia project made an explicit decision to make all content free to access and free of advertisements, funding operations instead through donations from appreciative users.

So just how much revenue is Wikipedia passing up on a monthly basis? Quite a bit it turns out; below we offer our monetization makeover for one of the world’s most popular websites, outlining how the property could be earning hundreds of millions of dollars every month, amounting to roughly $2.3 billion annually.

Our assumptions on traffic are based on the stats that the ultra-transparent Wikipedia makes publicly available; for August 2016, all Wikimedia projects generated about 16 billion pageviews worldwide.

$160,000,000 Monthly Revenue Via Display Advertising

The biggest opportunity for Wikipedia is to place some banner ads throughout the site. Currently, there are no ads at all on Wikipedia; we’d suggest starting with three standard ad units:

  • 728 x 90 leaderboard
  • 300 x 250 medium rectangle
  • 160 x 600 skyscraper
  • Link unit at bottom of first section and again at the bottom of articles

Wikipedia Display Ads

This prevents the site from becoming too cluttered by ads (which would erode the user experience) while still giving the site plenty of opportunities to generate revenue.

Revenue Potential

Display Ads
Monthly PVs (000s) 16,000,000
CPM $10
Monthly Revenue $160,000,000

According to research firm Forester, average CPMs — the rate advertisers pay for 1,000 impressions — will rise 76%, from $2.66 in 2012 to $4.68 by 2017.

If we use that $2.66 figure for each of Wikipedia’s proposed ad units (leader board, skyscraper, etc.), we get to a bit over $10 per every thousand impressions ($2.66 x 4 ad units per page = $10.64). In reality, certain ad units would generate much higher CPMs than others (we expect the 300 x 250 medium rectangle ad space to be the top earner–perhaps closer to $4 per thousand impressions–and the link units to earn less than $1. But overall those rates seem about right for Wikipedia’s traffic, which is roughly in line with the Internet average.

$2,550,000 Monthly Revenue Via Affiliate Links

Another monetization opportunity comes in the form of affiliate links on article pages. Essentially, Wikipedia could begin directing visitors to relevant third-party merchant sites from their article pages. When these visitors become paying customers, Wikipedia would get an affiliate payment–a referral fee of sorts. Perhaps the easiest way to get the affiliate marketing revenue stream flowing is to partner with a well known merchant such as Amazon. We suggest eventually setting up multiple affiliate relationships in order to maximize conversions, but Amazon is a good place to start.

Wikipedia Affiliate

Revenue Potential

Affiliate Marketing
Monthly PVs 16,000,000,000
10% w/ Affiliate Links 1,600,000,000
Click Rate 0.25%
Affiliate Clicks 4,000,000
Conversion Rate 15%
Monthly Conversions 600,000
Average Ticket $50
Sales Generated $30,000,000
Commission 8.5%
Revenue $2,550,000

We’ll assume that about 10% of the approximately 16 billion monthly pageviews on Wikipedia should have affiliate links, and that those affiliate links will see a click rates of about 0.25%. That translates into about 4 million affiliate clicks each month. Assuming a conversion rate of about 15% and average purchase of about $50, Wikipedia could generate almost $30 million in monthly Amazon sales.

At an 8.5% commission, Wikipedia could earn about $2,55 million monthly from an affiliate relationship with Amazon. That conservative estimate could get pushed higher with the addition of affiliate links to more pages (we’re assuming only 10% of pages would have them) and more targeted affiliate relationships.

$76,800 Monthly Revenue Via Lead Generation

Many pages on Wikipedia would be good fits for lead generation forms, allowing the site to collect contact information for visitors and sell it to vendors who might be able to sell them a relevant product or service. For example, Wikipedia’s page on car insurance could feature a widget that prompts visitors to enter their email and ZIP code for deals to see insurance rates. Wikipedia can then sell this information to insurance companies, who could then email plan information to that visitor.

Wikipedia Lead Gen

Revenue Potential

The Wikipedia page on car insurance had about 70,000 pageviews in August 2016. Assuming a click rate of about 2%, a conversion rate of 20%, and a Cost per Lead (CPL) of $10, that page could be generating $2,800 monthly. That’s not a huge amount, but does represent a $47 CPM uplift ($2,800 / 60 = $46.67 per 1,000 pageviews). As highlighted above display advertising is expected to generate a CPM of about $10, so this increase is significant.

Below is a rough estimate of earnings potential for a handful of insurance-related Wikipedia pages in August 2016:

Page Monthly PVs Click % Conversion % CPL Monthly Revenue
Car Insurance  70,000  2% 20% $10 $2,800
Health Insurance  23,000  2% 20% $10 $920
Homeowner Insurance  8,000  2% 20% $10 $320
Life Insurance  91,000  2% 20% $10 $3,640
Total 192,000 $7,680

Based on our knowledge of the lead generation vertical, insurance represents about 10% of the total market. So if we assume that the $7,680 represents about 10% of Wikipedia’s potential lead gen revenue, we can estimate that Wikipedia could earn $76,680 in monthly lead generation revenue.

$375,000 Monthly Revenue Via Email Monetization

Wikipedia is currently missing out on an opportunity to build a massive database of email addresses that can become a regular revenue stream. With a few minor tweaks, Wikipedia could capture millions of email addresses and earn substantial revenue from them each month. We suggest creating a free e-newsletter to which visitors could subscribe–we’ll call this the Daily Wiki. There’s no need to create additional content; this email could simply highlight a particularly interesting or timely Wikipedia page (basically, what’s already being done on the home page).

Daily Wiki

While this newsletter subscription would be completely free, Wikipedia could monetize it in two ways:

  1. Sell Sponsorships. The daily newsletter could be presented as being “brought to you by Toyota” (or any other sponsor), with a sponsor logo appearing within the email.
  2. List Rental. Subscribers to the newsletter could have the opportunity to opt-in to emails from Wikipedia’s partners–essentially allowing Wikipedia to rent out those email addresses for third-party mailings.

This newsletter could be promoted via a subscription box in the left sidebar (see the top of this page for an example) as well as links within content. We’d also suggest experimenting with a pop-up that presents visitors with a chance to sign up for the daily newsletter.

Revenue Potential

Email Rental
Daily Wiki Subs 5,000,000
3rd Party Opt In % 10%
Opt-In Email Subs 500,000
Dedicated Mailing CPM $20
Revenue Per Sponsored Mailing $10,000

By positioning the newsletter prominently to Wikipedia’s more than 500 million monthly visitors, we estimate that the newsletter would capture 1% of those visitors, or five million names, within three months.

We’ll assume that 10% of those, or 500,000, opt in to third-party mailings. It would be reasonable for Wikipedia to rent out each name on that list a total of once a month at a CPM of $20. That translates into $10,000 in monthly revenue from third-party emails. This figure could be multiplied if multiple mailings were sent to each address. Weekly mailings, which would generate upwards of $40,000, would not be unreasonable.

Newsletter Sponsorship
Subscribers 5,000,000
Sponsorship Cost $25,000
Sponsorships Sold/Month 15
Monthly Revenue $375,000

Meanwhile, sponsorship of the Daily Wiki (which goes out to the full list of five million) should fetch $25,000 for each send. If Wikipedia is able to sell even half of its available inventory, it could generate $375,000 each month.

Between sponsored third-party mailings and sponsorship of its daily newsletter, Wikipedia could generate $385,000 in monthly revenue from email.

$1,093,750 Monthly Revenue Via Wikipedia Store

Given the tremendous recognition of the Wikipedia brand, we suggest the opening of an online store where visitors would be able to purchase branded Wikipedia merchandise. We’re thinking coffee mugs, polo shirts, pens, etc.–the standard fare for an e-store. After all, who wouldn’t want to sport a cool Wikipedia polo?

Wikipedia Ecommerce

Revenue Potential

Wikipedia Store
Monthly Visitors 500,000,000
% Visit Store 1%
Store Visitors 5,000,000
Conversion Rate 3.5%
Store Shoppers 175,000
Average Purchase Price $25
Monthly Gross Sales $4,375,000
Profit Margin 25%
Monthly Net Revenue $1,093,750

Estimating revenue that could be generated from an online store is a bit tricky, but we can apply a few rules of thumb to come up with a rough estimate. Let’s assume that 1% of the 500 million monthly visitors end up at the Wikipedia Store, a conservative estimate if a link was positioned prominently (such as in the nav bar).

E-commerce sites have an average conversion rate in the neighborhood of 3.5%, which would translate into 175,000 paying customers for Wikipedia. If we use an average ticket price of $25, Wikipedia could be generating $4,375,000 in monthly sales at its online store. 

Of course, not all of that would be profit; at a 25% margin (which is probably conservative), net income would be $1,093,750

$25,000,000 Monthly Revenue Via Wikipedia Premium

Currently all visitors to Wikipedia share the same experience: free access to unlimited articles. The creation of a premium membership to Wikipedia could generate another recurring revenue stream. Charging for access to Wikipedia articles would likely result in significant erosion of the goodwill built up by Wikipedia (not to mention the audience), so we don’t see that route to be a viable option for a premium package. However, there are still plenty of options for creating a valuable membership package for which users would be willing to pay. In other words, the current site would remain completely free but additional features would be added pas part of a premium package.

We suggest that the “Wikipedia Premium” include some combination of:

  • Ability to set alerts for email notification when certain articles are updated
  • Option to immediate download any article into PDF form
  • A email address
  • Weekly members-only newsletter

I’d personally be happy to fork over $10 a month for that package, and I’m guessing many more Wikipedia users would be in the same boat.

Wikipedia Premium

Revenue Potential

Wikipedia Premium
Monthly Visitors 500,000,000
Upgrade % 0.5%
Premium Members 2,500,000
Monthly Fee $10
Monthly Revenue $25,000,000

A detailed subscription revenue model would start from a base of zero and factor in monthly attrition and conversion rates. For simplicity’s sake, we’ll assume that within six months Wikipedia could get 0.5% of the 500 million people who visit the site monthly to sign up for the premium product (that’s about 2.5 million people). If priced at $10 per month–a price point we think could generate the aforementioned conversion levels–Wikipedia could be generating $25 million in premium subscription revenue each month.


If Wikipedia were to implement the monetization techniques highlighted above, we estimate the site could be generating monthly revenue of $239,594,325.

Monetization Method Monthly Revenue
Display Advertising $160,000,000
Affiliate Marketing $2,550,000
Lead Generation $76,800
Email Rental $375,000
Wikipedia Store $1,093,750
Wikipedia Premium $25,000,000
Total Monthly Revenue $189,095,550

To put that in perspective:

  • In the 10 minutes it took to read this article, Wikipedia could have earned roughly $44,000.
  • With a Price / Revenue multiple of 5x Wikipedia could have a market capitalization of approximately $14 billion, which would make it slightly larger than Netflix in terms of value. (As a point of comparison, Facebook currently trades at about 10.5x revenue.)
  • At four ad units per page, Wikipedia would add about 84 billion monthly ad impressions to the global inventory, or about 1 trillion ads each year. Last year a total of 5.3 trillion display ads were served, meaning that Wikipedia could increase the global supply of display ads by nearly 20%.


  1. Good analysis here, Michael. Very well thought out. But I think you may have underestimated lead generation revenue by a wide margin. As you know, I have some education lead gen experience. So I thought I would look into just one of Wikipedia’s degree-based pages. Their page on the Doctor of Nursing Practice degree got close to 12,000 views in May 2013, according to . CPLs for graduate-level nursing programs can often exceed $60. Assuming that this page would convert at a pretty high rate, I estimate that this one page alone has the potential to generate $10,000 in monthly revenue if monetized properly. (I’ll spare you the nitty gritty math.)

    Now that’s just one page that I did a bit of research on. Assuming that Wikipedia has 100 other similarly-trafficked degree-based pages (there are likely more than 100), it’s not unreasonable to extrapolate that edu-based lead gen alone could generate $1 million monthly revenue. Obviously, a lot of this is really rough “back of the napkin” math and I’m making a few assumptions about conversion rates, but I think the potential is there for six figures monthly just in this one vertical. Curious to hear others’ thoughts.

  2. Andy Hagans says:

    Jimmy, your point is well taken. BUT, I have to think even if Wikipedia DID implement lead gen monetization, they wouldn’t become experts at it, and they’d likely have some sort of implementation that left a lot of the potential revenue on the table. Juicing / increasing rev yield with lead gen creatives is such specific (and rare) skill, that I think Michael has the right idea to solidly underestimate “potential” lead gen revenue. Though, maybe he oughtn’t — after all, the analysis in this article is all academic anyway!

  3. Good point, Andy. I don’t think they’d become experts at it either (at least not right away).Though they might after a year or two, if they had the motivation. Anyway, I still believe that the *potential* exists to turn Wikipedia into a lead gen machine that could generate seven figures monthly. Certainly, the traffic is there. How effectively they’d be able to extract value from that traffic is another matter I suppose.

  4. This is funny, teaching people how to make money on a product other people create.
    Wikipedia is great, but flawed. If it died today, nobody would suffer: all Wikipedia has can be found in countless of other places – and more accurate, too.
