Update timeline: exact dates
According to Google Search Central, the February 2026 Discover Core Update started on February 5, 2026. In Google Search Status Dashboard, this rollout is marked as completed on February 27, 2026.
The key point: do not judge performance by one day. Compare at least 2-4 weeks before launch and 2-4 weeks after completion.
For example, if traffic dropped sharply on February 10, it does not automatically mean the site is broken. Mid-rollout swings are common. What matters more is the average weekly trend after February 27.
What this may mean for Google Discover traffic
These updates affect not only rankings, but also how often your content appears in recommendations. So even with stable SEO traffic from Search, Discover can show sharp ups and downs.
In most cases this is tied to:
In simple terms: the same article can get high visibility one week and almost disappear the next. That is not always a site issue; often it is algorithmic re-evaluation of quality and audience interest.
- re-evaluation of content usefulness for specific audience segments;
- source trust signals and overall brand stability;
- quality of packaging: headlines, visuals, CTR, and retention.
What to check on your site after the update
- Segment your Discover report in GSC by topic. Track impressions and CTR, not only clicks.
- Compare top pages before and after February 5-27. Identify which formats stayed stable and which dropped.
- Review headlines and visuals. In Discover this strongly impacts click-through rate.
- Check post-click behavior. If users leave quickly, repeat exposure can decrease.
- Add more transparency. Author profile, updated date, sources, and clear value for the reader.
If you cannot run a full audit, start with 10-15 URLs that lost the most impressions. This quickly shows whether the issue is local (specific topics) or sitewide.
Practical 2-week plan
Week 1: review strongest and weakest pages, refresh weak content, and improve titles and preview assets.
Week 2: publish 3-5 new pieces in topics that historically perform best in Discover, with strict source quality checks.
The simple rule: do not try to fix everything at once. Double down on formats and topics that already work for your audience.
A practical tip: keep a simple log \"what was changed / when / result after 7-14 days.\" This makes it easy to see which updates actually drive growth.

When did the February 2026 Discover Core Update happen?
Google announced the start on February 5, 2026 and completion on February 27, 2026.

Because Discover independently evaluates audience interest and may show content more or less often in recommendations.
Which metrics should I check first?
In GSC, review impressions, clicks, and CTR by topic and URL. Then check post-click behavior: time on page, depth, and return rate.
When can I make reliable conclusions?
Usually after 2-4 weeks following rollout completion, when the trend becomes more stable.
