Is core web vitals important?
Posted by oceane-tan on October 10, 2025 at 12:53 pmHi I have a niche business website to share related knowledge and information. The traffic is dropping since July 2025 (from 140k visitor till 50k visitors).
I saw there is poor performance on mobile site in core web vitals in GSC.
After I changed to light-weight theme, now both mobile and desktop site are good performance.
But my traffic still not growing up, what else should I check?
Thank you in advance.

GuestOctober 10, 2025 at 1:21 pmthanks for demonstrating that CWVs do not “help” SEO.
You need to build great content and lift your sites visibility

GuestOctober 10, 2025 at 2:22 pmWeb Performance (and Web Vitals) are important for SEO, but much more important for users and their experience.

GuestOctober 10, 2025 at 3:05 pmThe only one who cares about cwv is the end user but that’s only if your website takes ages to load so they will bounce, google doesn’t give a damn about it in my opinion. So it matters but it doesn’t 🙂

GuestOctober 10, 2025 at 4:38 pmThere has to be another reason. You (and I mean your whole infrastructure, including your hosting) must have done something before July, probably in the two or three months prior. You don’t lose 73% overnight because of content or authority; it makes absolutely no sense. If you had good enough content and authority to have 140k before you got hit, then it’s nonsensical to think everything went bonkers the next day. The only logical explanation is a technical issue, so think carefully about what could have happened. Sadly, changing a theme and making it faster not only won’t help, but it might hide the real issue. Whatever it was, it was affected by the June core update, which ended in mid-July.
Anyway, take this as a checklist:
* besides thinking about any possible changes, check GA4 (hopefully you use it) and see if you had any weird spikes or anomalies such as bot attacks, sudden bursts of traffic, or strange referrals. Keep in mind this happened before the hit, so check April to June at least.
* Check your current referrals. Which source was most affected? Google? AI? Direct traffic? Other search engines? If only Google, that reinforces the idea of a technical issue. In our experience, 90% of the time when Google takes you down like that, it’s because of a JavaScript problem. Think of any script or plugin you added.
* Check your competitors. What happened to them? If they simply moved up to your previous positions, then it’s a problem on your end for sure. However, if you see new competitors you hadn’t noticed before, then there’s probably some parasite or PSEO sites that took you (and your competitors) down.
* Last but not least, there’s a chance this isn’t technical but related to your own actions. Were you spamming or using low-quality links or black-hat tactics? If so, that’s the explanation, though I doubt it, because if it were that bad, you’d be deindexed completely. -

GuestOctober 11, 2025 at 3:41 amSEO is a complete recipe and Core Web viral is one of the parts of it
It will improve but you need to check the following things
✔️ Content context and seeing more scope in your content
✔️ Page wise backlink strength
✔️ Competitor analysis and seeing gap in content
✔️ Guest post or Brand mention as AI visibility is very much relying on brand mention
✔️ Check search console and see which pages have lost impressions and clicks, impression is somehow lost after removing &num=100 parameter that have affected impressions
SEO needs deep research and produce results on the basis of overall analysis and rework
Things will be back on track again soon

GuestOctober 11, 2025 at 6:49 amYes, **Core Web Vitals (CWV) are important**, but they are **just one part of the ranking puzzle**. Good CWV improves user experience and can prevent ranking drops, especially on mobile, but fixing them alone doesn’t guarantee traffic growth.
Since you’ve already improved your site’s performance, here are other areas to check:
1. **Content Relevance & Quality**
* Update old posts with fresh information.
* Check if your content still matches user intent.
2. **SEO & On-Page Optimization**
* Titles, meta descriptions, headings, and structured data.
* Internal linking to boost crawlability and user flow.
3. **Search Intent & Keyword Shifts**
* Some keywords may have become more competitive or user intent may have changed.
* Use tools like Google Search Console and Keyword Explorer to spot trends.
4. **Backlinks / Domain Authority**
* Even if your content is good, lower authority compared to competitors can limit ranking.
* Earn natural backlinks through guest posts, resource pages, or outreach.
5. **Technical SEO**
* Check for crawl errors, indexing issues, or mobile usability problems.
* Ensure XML sitemaps and canonical tags are correctly set.
6. **User Engagement Metrics**
* High bounce rate or low dwell time can signal poor user experience, even if CWV is good. -

GuestOctober 11, 2025 at 11:37 amI have seen that minor technical issues can lead to worse performance but fixing them doesn’t tend to lead to upticks. Basically Google sees people bouncing cause load time issues broken links etc. and denegrades your da you fix it but you already have that history, you need the remaining users to have a great experience, improve content, run paid campaigns get fucked by Google
