December 2021: Google rolls out its second product reviews update
Covers December 2021. Part of our search timeline: a month-by-month look at the changes that shaped SEO, AI search, paid ads and social media, written in November 2026 for local businesses with the benefit of hindsight.
Quick answer: Google put out its second product reviews update in December 2021, along with new guidance asking reviewers to prove they had used the product, for example with photos or audio, and to give readers links to several sellers where that’s useful. It made clear that detailed, genuine reviews would carry on gaining ground in search.
Looking back from November 2026, this search timeline entry covers December 2021. It matters to local businesses that write about the products they fit or sell, whether that’s a heating engineer comparing boilers or a garage writing about tyre brands.
What Google changed in December 2021
Google refreshed its advice for review content. It encouraged visual proof that products had really been tested, plus links to a range of retailers so readers had a choice of where to shop. The rollout took several weeks to complete.
Why review content had to raise its game
UK retailers and publishers found their review and comparison pages had to earn their place. Thin “top ten” lists slipped behind content that obviously came from people who had used the products.
For a trade business, that’s good news. An installer who has fitted dozens of a particular boiler model has exactly the kind of first-hand experience Google was asking for.
How to write reviews that hold up today
- Add your own photos or videos showing products in real use, such as a unit you’ve installed in a customer’s home.
- Weigh products up against the alternatives and say who each one is right for.
- Refresh reviews when products change or new models come out.
Frequently asked questions
Do my reviews need my own photos?
Google recommends evidence like images of you using the product. Your own photos are a strong signal of real experience.
Should I link to more than one shop?
Google suggested it can help readers. If you’re reviewing products you sell or fit yourself, concentrate on honest, detailed information.
