Thin Affiliate Content Diagnosis
A page is thin when it adds nothing a reader could not get from the operator or from your other pages. Find those pages with Google's own definitions, then improve, merge or remove each one under a rule you write down.
In brief
- Google: thin affiliation is publishing affiliate links where "the product descriptions and reviews are copied directly from the original merchant without any original content or added value".
- Google: affiliate pages can be thin when distributed "across a network of affiliates without providing additional value".
- Google: scaled content abuse is generating many pages "for the primary purpose of manipulating search rankings and not helping users".
- For each weak page, decide: improve, merge, or remove, and record why.
Signals of thin pages
| Signal | How to detect | Relates to |
|---|---|---|
| Text copied from operator pages | Compare review text with the operator's own descriptions | Thin affiliation |
| Same template text with only the brand swapped | Near-duplicate detection across reviews | Scaled content abuse |
| No first-hand evidence | No tests, screenshots or measurements on the page | Google's review guidance |
| City or state pages with identical bodies | Diff pages in a location series | Scaled content abuse |
| Third-party content placed on a strong host to rank | Pages written by others with little host oversight | Site reputation abuse |
| Pages for markets where the product is not legal | Check against regulators' registers | Accuracy and legal risk |
Decision rule
- Improve when the page answers a real question you can support with tests or sources. Add evidence, market facts and dates.
- Merge when several pages answer the same question. Combine them into the strongest page and redirect the rest.
- Remove when the page exists only to target a keyword, covers a market where the product is not offered legally, or cannot be supported. Return a 404 or 410, or redirect if a close equivalent exists.
- Record each decision with date and reason in the editorial log.
About third-party content
Google's site reputation policy applies "where third-party content is published on a host site mainly because of that host's already-established ranking signals". Its reviewers consider whether content was "created with sufficient input, editorial oversight, or contribution from the host site". If you publish partner-supplied reviews or coupon sections, they need the same evidence and editorial control as your own pages, or they should not be there.
Worked example (synthetic)
Synthetic example. Invented names and figures that show the method. No real operator, site or test is described.
A site has 40 casino reviews built from one template. An editor samples ten. Seven repeat the operator's own description of its games almost word for word, and none shows a screenshot or test date. Under Google's thin affiliation wording, those seven add no original value. The editor sorts them under a written rule: three operators the team can test again in the next month are rewritten with first-hand evidence; two that overlap with stronger pages are merged and redirected; two operators no longer licensed in the target market are removed. Each decision goes into the update log with its date and reason, so the next audit can see what changed.
Questions
Is using a review template thin content?
No. A shared structure is fine. Thin content comes from repeating the same text with names swapped, or from pages without original information. Fill the template with product-specific evidence.
Should I delete or noindex weak pages?
Improve pages that answer real questions. Merge duplicates with redirects. Remove pages that cannot be supported. Noindex can hide a page from search, but it leaves the weak page in front of readers.
Do AI-written reviews count as thin?
Google's concern is pages made primarily to manipulate rankings, however they are produced. A review still needs first-hand evidence and editorial review. Google also asks whether the use of automation is clear to visitors.
