The thread is arguing about whether "it" works while using one word for three arrangements that are enforced differently. I want to separate them, because once they're separated most of the disagreement here dissolves.
The three things people call parasite
- Hosted third-party directory. A subfolder or subdomain leased wholesale. The host has no editorial involvement. Hundreds to thousands of pages. This is the arrangement the policy was written about and the manual actions in November went at it directly.
- Sponsored or partner section. The host has a section, labelled or not, where paid pieces run. Someone at the host reads them. Volume is tens of pages, not thousands.
- Single placement in the main editorial body. One article, indistinguishable in template and treatment from the site's normal output, commercially motivated.
The policy language is about content published "with little or no first-party oversight or involvement" for the purpose of manipulating rankings. That phrase does real work. It is not about payment and it is not about commercial intent. It is about oversight. Read that way, 1 is squarely in scope, 3 is squarely out, and 2 is the entire battleground.
Why the November wave looked total
Because manual actions are cheap to apply at the directory level. A reviewer looks at one subfolder, sees ten thousand pages of a pattern, and actions the section. The same reviewer cannot economically evaluate one article on page nine of a trade publication, and there is no signal that reliably separates a paid editorial piece from an unpaid one at scale.
This is the part I would emphasise to anyone reading and deciding: enforcement follows what is cheap to detect. Not what is worst.
What changes that
An algorithmic version. Everything so far has been manual and the manual approach cannot reach arrangement 3. If a classifier ships that scores sections rather than sites, the middle category goes overnight and the bottom one gets a lot more uncertain. I would expect that to be attempted this year. I would not expect it to be good, because the training signal is genuinely hard to obtain.
What I'd do with money right now
- Stop paying for 1. This is not a judgement call any more.
- Treat 2 as a wasting asset. Keep placements that already rank, don't sign a new twelve-month contract, price the expected life at two quarters.
- Keep doing 3 if you can afford it, understanding that its main defence is that it is expensive to detect, which is a defence that erodes.
What I'm unsure about
Whether a host site being penalised at the directory level drags down its main content, and therefore whether a category 3 placement on a site that also runs a category 1 directory is contaminated by association. I have one case that suggests yes and one that suggests no, and one each is nothing.
Summary: three arrangements, one word, and the argument in this thread is people defending different ones.
