Starting in April 2021 and repeated in several subsequent iterations through 2023, Google's Product Reviews Updates targeted a specific, common content type: reviews that summarise a product's specifications without any evidence the reviewer actually used it. These updates rewarded genuine, evidence-based reviews and demoted thin, templated ones, particularly on affiliate-heavy sites.
What separates a genuine review from a thin one, by Google's own criteria
Google published specific guidance on what a high-quality review demonstrates: expert knowledge of the product category, evidence of hands-on testing (photos, measurements, personal observations), comparisons against similar products, and honest discussion of a product's shortcomings, not just its advertised strengths.
- Original photos or video of the product actually being used, not manufacturer stock images.
- Specific measurements or test results, not just restated specification sheets.
- Honest coverage of downsides and limitations, not only marketing-friendly positives.
- Comparisons to specific alternative products, based on genuine, comparable criteria.
Why thin affiliate content struggled the most
A common, high-volume tactic before these updates was publishing large numbers of review pages that simply restated a product's listed specifications, added a generic 'pros and cons' list, and inserted an affiliate link — with no actual evidence the writer had ever used the product. This pattern was exactly what the updates were designed to identify and demote.
A review page that could have been written entirely from the product's own spec sheet, without ever touching the product, is precisely what these updates were built to catch.
The connection to E-E-A-T
The Product Reviews Updates are best understood as a specific application of the broader E-E-A-T framework, particularly the Experience component added in 2022 — a review demonstrating genuine first-hand experience is exactly the kind of signal Google formalised when it expanded E-A-T to E-E-A-T.
What to do if your review content was affected
Adding genuine, specific evidence retroactively — real photos, updated testing detail, honest limitation discussion — to existing thin reviews is often more effective than writing entirely new content, since it directly addresses the exact gap these updates evaluate. Google's own review guidance outlines this expectation in detail.
- Retroactively add hands-on testing evidence to existing thin review pages.
- Include comparison content against real, named alternatives.
- Disclose affiliate relationships and how products were sourced (purchased, provided for review) transparently.
Frequently asked questions
Does this update only affect affiliate sites?
It primarily affected review content regardless of monetisation method, but affiliate-heavy sites were disproportionately impacted because thin, spec-restating reviews were a particularly common pattern in that category.
Can I reuse a manufacturer's product images in a review?
You can, but relying solely on manufacturer imagery, with no original photos or evidence of hands-on use, is exactly the pattern these updates evaluate negatively — original evidence matters more than image sourcing alone.
Is there a minimum word count for a good review?
No specific word count is required — the standard is evidentiary depth and honesty, not length. A shorter review with genuine, specific testing evidence outperforms a long one that only restates specifications.

The takeaway
Add genuine, specific evidence of hands-on testing to your product reviews — measurements, comparison photos, real usage detail — since this is exactly what the Product Reviews Update series was built to reward.
