Content Farms and Link Farming: How They Destroy the Internet and Trust

01What are content farms and link farming?

A content farm is a website whose main goal isn’t value for the reader, but generating as many pages indexed by search engines for as many phrases as possible. The business model is simple: the more pages, the more visits from search engines, the more ad impressions or clicks on affiliate links. Quality is a secondary variable here — scale is what counts.

A classic example is the American company Demand Media and its website eHow — at their peak, they published thousands of short, poorly verified articles a day, written en masse by low-paid freelancers for predetermined, popular search phrases. In February 2011, Google responded with an algorithm update known as Panda, aimed directly at content farms — it affected as much as 11.8% of all queries in the US, more than any previous update. Demand Media later reported a loss of 6.4 million dollars in one quarter, partly because of Panda.

Link farming is the equivalent of the same phenomenon on the link side, not the content side. Instead of mass-producing articles, networks of websites are created whose only purpose is to link to each other or to one target website — artificially inflating its authority in the eyes of the algorithm. The best-known form is PBNs (private blog networks) — sets of seemingly independent sites, often based on expired domains with a history, actually controlled by a single owner solely to build links.

02How content farms and link farming work in practice

The mechanics are usually similar: the target page receives links from dozens or hundreds of weak, loosely related websites — bought, exchanged, or created specifically for this purpose. A common variant is triangular link exchange (site A links to B, B to C, C to A), which is meant to hide the direct relationship between the sites from the algorithm. Another is using expiring domains with an established history and real authority, which are taken over and filled with new, unrelated content solely to exploit their old reputation.

A newer, more sophisticated variant is so-called keyword swarming — a practice described in 2024 by HouseFresh, a small, independent reviewer of air purifiers. According to an account by a former employee of the large publisher Dotdash Meredith, the company deliberately “swarmed,” publishing a dozen or so articles on a topic in which the independent site ranked high — in order to overwhelm it with numbers and push it down the results. HouseFresh lost most of its search traffic this way.

A third phenomenon, increasingly penalized by Google, is site reputation abuse , also colloquially called “parasite SEO” — publishing weak, commercial content on a subdomain or in a section of a large, trusted brand to take advantage of its authority. A high-profile example is Forbes Advisor, which, according to industry estimates, earned about 236 million dollars a year from this kind of content before Google tightened its policy on the matter in 2024.

These aren’t single, isolated incidents. Below are examples, documented and repeatedly confirmed in independent sources, of how content farms and link farming have really affected the quality of search results — from 2011 to the present day.

04Why content farms destroy trust in the internet

The consequences of content farms and link farming go far beyond rankings in Google. When search results fill up with content optimized for the algorithm rather than the reader, independent creators lose — smaller, specialized websites run by people with real knowledge, like HouseFresh, which physically tested equipment instead of paraphrasing product descriptions from Amazon. Increasingly, it’s precisely such voices that disappear from the results, pushed out by entities with bigger budgets for content production at scale, not greater subject-matter knowledge.

This phenomenon fuels the discussion around the so-called dead internet theory — the claim that an ever-larger share of online activity is generated not by people, but by bots and automated systems. Not long ago it was treated as an internet curiosity. Today, with 51% of web traffic coming from automation and more than a third of new pages created with the help of AI, it’s increasingly hard to dismiss it as pure conspiracy theory — Stanford researchers estimated that we are already about 17% of the way toward a scenario in which the web is dominated by content not created by humans.

The problem also has a practical dimension for the reader: since it’s increasingly hard to tell content written by an expert from content mass-generated for keywords, the risk grows that we make decisions — about purchases, health, finances — based on material that no one has ever verified in practice.

05How Google responds to content farms and link farming

For fifteen years, Google has been waging something like an arms race with content farms and link farming — every major algorithm update forced new, more sophisticated ways of getting around the rules, which the next update then responded to.

None of these updates solved the problem permanently — each one limited one tactic, after which another appeared, adapted to the new rules. That’s why responsibility can’t rest solely with the algorithm. A reader who knows how to recognize a content farm is a much harder target than one who trusts every result on the first page.
