Sometimes a core update does not just reshuffle the same kinds of pages. It changes the kinds of pages that rank at all. A query that used to return ten product category pages suddenly shows buying guides and forum threads. A "how to" search that favoured brand blogs now leads with videos and Reddit discussions.
SEOs often describe this as a search intent shift: Google's systems appear to have changed their view of what searchers want from a query. If that is what happened, polishing your existing page will not help much, because the page type itself no longer matches what is ranking.
This article explains what intent shifts look like during core updates, what Google has and has not said about them, dated examples from industry tracking, and a step-by-step method to detect a shift in your own data.
Key Takeaways
- An intent shift is when the type of content ranking for a query changes, for example from commercial pages to informational guides or discussion forums.
- Google has not published a list of intent changes in any core update; "intent shift" is an industry interpretation of observed SERP changes.
- Industry tracking summarised on Wikipedia noted video sites gaining in May 2022 and user-generated content such as Reddit gaining in August 2023.
- You can detect a shift by comparing the page types in the top results before and after an update.
- The response is to match the format searchers now get, or to target queries where your page type still fits.
What a search intent shift is
Search intent is the goal behind a query: learning something, comparing options, buying, finding a specific site or visiting a place. Our search intent guide covers the categories in detail.
Google's ranking systems try to work out which pages best satisfy a query. Its in-depth guide to how Search works says relevance is determined by hundreds of factors. When a core update changes how those systems interpret queries or judge usefulness, the mix of page types at the top can change. Google itself frames core update movement as relative:
“restaurants that move down aren’t necessarily “bad”; there are just other restaurants that make your top 20.”
— Google Search Central, Google Search's core updates
An intent shift is an extreme version of that: the "other restaurants" are a different kind of restaurant altogether.
Confirmed versus interpreted
It is important to be precise here. Google confirms core updates and their dates, and says they are broad improvements to its systems. It does not say "this update reclassified the intent of these queries". When analysts describe an intent shift, they are interpreting SERP data. That interpretation is often useful, but it is not an official explanation.
Common types of intent shift
| Shift | Before | After | What it suggests |
|---|---|---|---|
| Commercial to informational | Category and product pages | Guides, comparisons, "best X" articles | Searchers are still researching |
| Informational to commercial | Long explainers | Product pages, tools, pricing pages | Searchers are ready to act |
| Brands to forums and UGC | Publisher and brand content | Reddit, Quora, community threads | Preference for first-hand experiences |
| Text to video | Articles | YouTube and short-form video | Visual demonstration helps |
| Generic to local | National pages | Local pack and local businesses | Proximity matters for the query |
| Single answer to mixed SERP | Similar pages | Varied page types | Query is ambiguous; Google diversifies |
Dated examples from industry tracking
Wikipedia's Timeline of Google Search summarises industry analysis of several core updates. These are observations by third parties, not Google statements:
- May 2022 core update (25 May–9 June 2022): the timeline says news and media publishers were negatively affected, reference sites "like dictionaries, unofficial Wikis, lyric websites, and stock photo sites" dropped, and video sites such as YouTube and TikTok "saw the largest gains in ranking."
- August 2023 core update (22 August–7 September 2023): the timeline says "the biggest gains seemed to be felt by UGC and Reddit," as well as sites showing evidence of experience in the subject. See our post on the August 2023 core update and our guide to algorithm updates for forums and UGC sites.
- June 2025 core update (30 June–17 July 2025): the timeline notes reports of partial recoveries for some sites hit by the September 2023 helpful content update.
Patterns like these are consistent with intent re-evaluation (for example, more weight on first-hand discussion), but they could also reflect changes in how quality is assessed. Often it is both.
Why intent can shift
- Changing searcher behaviour. Testimony at the US antitrust trial, reported by Search Engine Land, described systems such as Navboost that use past click data. If people's behaviour on a query changes, systems that learn from interaction data may reflect that over time.
- Better language understanding. Models like BERT, which Google began using in Search in 2019, help interpret queries more precisely.
- Quality reassessment. If Google's systems decide a page type is generally more helpful for a query (for example, first-hand accounts), more of that type rises.
- New SERP formats. AI Overviews and other features answer some informational needs directly, changing what the organic results need to provide.
How to detect an intent shift step by step
- Pick affected queries. In Search Console, find queries where your clicks dropped most after the update completed.
- Record the current top 10. For each query, note the page type of each result: product, category, guide, forum, video, local, tool.
- Reconstruct the "before" SERP. Use your rank tracker's SERP history or saved snapshots from before the update.
- Compare the mix. If the share of a page type changed sharply (for example, guides from 2 of 10 to 7 of 10), you likely have an intent shift.
- Check your page type. Does your page match what now ranks? If not, the problem is format, not quality alone.
- Group by template. If every category page lost but every guide held, look at the pattern across templates. Our post on template-level update analysis explains this.
- Decide the response. Create or adapt content to fit the new intent, or refocus on queries where your page type still wins.
Our guides to SERP competitor analysis after an update and before-and-after core update comparisons provide templates for steps 2 to 4.
SERP comparison worksheet
| Field | Before update | After update | Notes |
|---|---|---|---|
| Query | Same query, same location and device | Keep settings fixed | |
| Dominant page type | e.g. category pages | e.g. buying guides | Main signal of a shift |
| Number of forum/UGC results | e.g. 0 | e.g. 3 | Experience-led shift |
| Video results | e.g. none | e.g. carousel | Format shift |
| AI Overview present? | Yes/No | Yes/No | Affects clicks, not just rank |
| Your page type and position | e.g. category, #3 | e.g. category, #11 | Mismatch? |
How to respond to an intent shift
- Add the missing format. If guides now rank, publish a genuinely useful guide and link it to your commercial page. Our content writing service can help.
- Add first-hand experience. If forums and UGC rose, show real testing, photos, results and named authors.
- Don't twist the wrong page. Turning a product page into a 3,000-word essay usually hurts conversions without winning back rankings.
- Rebalance your keyword map. Assign each query to the page type that matches its current intent, as part of your SEO strategy.
- Optimise on-page signals. Make sure titles and headings reflect the intent clearly; see our on-page optimisation service.
Common mistakes
- Assuming quality is the only issue. A great page of the wrong type can still lose.
- Judging from one query. Look for patterns across a group of queries.
- Calling a shift during the rollout. SERPs can move several times before an update completes.
- Treating industry observations as Google confirmation. Label your analysis as interpretation.
- Chasing every forum result. Some UGC visibility reflects the query, not a sign you should start posting on Reddit.

Frequently Asked Questions
What is a search intent shift?
It is when the type of page ranking for a query changes, such as from product pages to guides, suggesting Google now sees the searcher's goal differently.
Has Google confirmed that core updates change intent?
No. Google confirms core updates and says they are broad, but "intent shift" is an industry interpretation of observed SERP changes.
Which updates showed noticeable page-type changes?
Industry analysis summarised on Wikipedia noted video sites gaining in the May 2022 core update and UGC and Reddit gaining in the August 2023 core update.
How do I know if my drop is an intent shift?
Compare the page types ranking before and after the update. If the dominant type changed and yours no longer matches, intent is likely involved.
Should I rewrite my product page as a guide?
Usually not. Create a separate guide for the informational intent and link it to the product page, keeping each page focused.
Conclusion
When a core update changes the type of content that ranks, the fix is not more polish on the same page but a better match with what searchers now get. Compare SERPs before and after, label your conclusions honestly, and build the format the query now rewards.
