The Google hidden gems update is the name Google gave to a change that surfaces content from “unexpected or hard-to-find places: a comment in a forum thread, a post on a little-known blog, or an article with unique expertise on a topic.” Barry Schwartz reported it on 16 November 2023 in Search Engine Roundtable’s coverage of the hidden gems ranking system. Most of what has been written since treats it as a forum update. That is half right. The forums gained because of what they contain, not because they are forums.
What the Google hidden gems update is
Google describes the target as material “based on personal insights and experiences”. The examples it gave are deliberately mixed. A forum comment, a post on a blog almost nobody has heard of, and an article with unusual expertise have little in common in format, authority or size. What they share is that the writer knows something from doing it.
That matters because the obvious reading, “Google now likes Reddit”, leads to the wrong response. Publishers who saw forums climb went off to seed threads and build community sections. The system was never described as rewarding a page type. It was described as finding experience wherever it happens to live.
How it rolled out, and where it sits
The launch was quieter than the announcement suggests. Google’s SearchLiaison account said the rollout began “several months ago” and added: “it’s been months and we’ve been improving and ramping it up since then to fully now.” So the November 2023 announcement marked full deployment, not a start date. Anyone looking for a single day when forum visibility jumped was looking for something that did not happen.
The more important detail is where the system sits. Many assumed it belonged to the helpful content system. SearchLiaison said otherwise: “it wasn’t part of that system. Instead, it was being tested as part of our core ranking systems. Since it’s fully launched now, that’s what we announced today — that it’s live and part of core ranking.”
| Claim you will see | What Google actually said |
|---|---|
| Hidden gems launched in November 2023 | Partly: the rollout began “several months ago” and was fully live by the announcement |
| It is part of the helpful content update | No: “it wasn’t part of that system” |
| It is a standalone filter | No: it was tested within, and is now “part of core ranking” |
| It rewards forums | It rewards “personal insights and experiences”, including forum comments |
| Big sites cannot benefit | Not stated: the examples include “an article with unique expertise on a topic” |
Being part of core ranking has a practical consequence. There is no separate hidden gems penalty to recover from and no separate update to wait for. If your visibility moved, it moved as part of how core ranking now weighs experience, and changes show up through the same core updates as everything else. Our guide to core update winners and losers covers how to read those movements without inventing causes.
Why forums gained, and why copying them misses the point
Forums gained because a good thread is dense with first-hand detail. Someone asks which tent leaks in crosswinds; five people who own those tents answer, one with a photo of the seam. No product roundup assembled from manufacturer pages can match that. Our post on Reddit SEO covers what the rise of threads means for publishers who compete with them.
Copying the format does not copy the substance. A comment section on a thin review adds no experience. A fake “community” page of rewritten questions adds less. The thing being surfaced is the knowledge, and the forum was simply where it already sat.
The same applies to small blogs. Being little-known is not the qualification, it is just where Google said it used to struggle to find good material. A small blog full of generic summaries is still a small blog full of generic summaries.
Large publishers are not excluded either. Google’s third example, “an article with unique expertise on a topic”, says nothing about the size of the site it sits on. A specialist writing from long practice on a big domain fits the description as well as a hobbyist on a free blog does.
What to change on your own site
The useful response is to make the experience on your pages visible and specific. That overlaps heavily with what the helpful content update aftermath taught: sites that rewrote consensus lost ground, and sites with their own material held on. Hidden gems is a different system, but it pulls in the same direction.
- Show the work. Your own photos, screenshots, measurements and the problem you hit on day three.
- Name who did it. An author with a real record in the topic, stated on the page.
- Cut the consensus padding. Sections that repeat what every ranking page says add length, not value.
- Answer the follow-up question. Forums win because people ask “but what about…” and someone replies. Do that in the article.
- Keep opinions attached to evidence. A recommendation backed by what you tested reads as experience; a bare verdict does not.
Our E-E-A-T examples show what experience looks like on a real page, and the post on information gain in SEO covers how to check, before publishing, whether a page adds anything the ranking results lack. Both are more useful than any attempt to reverse-engineer hidden gems itself.
What this update cannot tell you
The limitation is that Google has described the goal, not the mechanism. Nobody outside Google knows which signals the system uses to recognise personal experience, how heavily they are weighted, or how it separates a genuine forum answer from a planted one. Claims that a particular phrase, schema type or first-person tone triggers it are guesses.
What you can control is the substance. If a page contains things only someone with direct experience could know, it is the kind of content Google said it wants to find, whichever system does the finding. If it does not, no format change will make it a hidden gem. Audit your top pages with one question: what here could a writer without hands-on experience not have produced? Where the answer is nothing, that is the page to rework first. Start with the pages that lost ground in the months around the announcement, since that is where the comparison with forum and small-blog results was sharpest, and judge each change by what it adds for a reader rather than by how it might look to a classifier.
Frequently asked questions
What is the Google hidden gems update?
A change that surfaces content “based on personal insights and experiences” from places such as forum threads, little-known blogs and articles with unique expertise.
Is hidden gems part of the helpful content system?
No. Google’s SearchLiaison said it “wasn’t part of that system” and was tested as part of the core ranking systems, where it now lives.
When did hidden gems launch?
It was announced as fully live in November 2023, but the rollout began “several months” earlier and was ramped up gradually.
Should I add a forum to my site?
Only if real people will use it. The system rewards first-hand experience, not the forum format, so an empty or seeded community adds nothing.
The takeaway Hidden gems rewards experience, not forums. Make what you know from doing the work visible on the page, and stop chasing the format of the sites that gained.
