The May 2026 Core Update wrapped on 2 June, but ranking instability in Google.pl and across international markets hasn't stopped. If your business operates in Poland and you're tracking both Polish-language and English-language keywords, you're likely seeing erratic position swings across multiple keyword sets. This is normal post-rollout behaviour - here's what it means for the Polish market specifically.
Post-Update Volatility in the Polish Search Market
Poland presents a specific context for Core Update volatility. Google.pl is a competitive but mid-sized market compared to Google.com or Google.de. Core Updates tend to produce more visible position swings in smaller national search markets because there are fewer competing domains to absorb the redistribution of positions.
The key fact: when Google rescores quality signals after a Core Update, it redistributes positions across competing pages. In Poland's market, a quality boost for a few dominant Polish-language domains can noticeably shift positions for international businesses competing in the same queries.
For English-language sites targeting Polish business audiences (international companies, export-oriented Polish businesses, English-speaking professionals in Poland), the May 2026 Core Update's effects play out slightly differently than for Polish-language sites:
English-language pages in Google.pl: These compete primarily against each other, not against Polish-language pages for the same intent. Volatility here reflects Google recalibrating which international English-language sources best serve Polish search intent.
Sites with both Polish and English content: If you maintain separate pages for Polish queries and English queries, each language set is evaluated independently. Volatility may differ significantly between them.
How to Assess Your Situation in the Polish Market Right Now
Check your GSC performance by country. In Google Search Console → Performance → filter by country: Poland. Compare clicks and impressions for the four weeks after 2 June against the equivalent pre-update period (May 5 - June 2). If Poland-specific traffic is roughly stable, you're seeing volatility, not genuine loss.
Check query-level data. Filter GSC queries to see which specific search terms are showing position swings. If top-performing queries are moving without a consistent downward trend, wait for stabilisation. If specific commercial queries show consistent position loss over two consecutive weeks, that warrants investigation.
Don't benchmark against competitors during the volatile period. If you check your position versus a competitor today, the comparison reflects volatility - not the actual post-update distribution. Wait until end of June 2026 for meaningful competitive analysis.
The Two-Scenario Framework for Poland
Scenario A - You're experiencing post-update volatility:
- Overall Poland traffic in GSC is within 10-15% of pre-update levels
- Rankings fluctuate across a range without consistent downward direction
- Multiple keyword groups are affected simultaneously
- Action: Do nothing. Wait until end of June 2026, then reassess.
Scenario B - You're experiencing genuine Core Update impact:
- Poland organic traffic in GSC is down 20%+ compared to pre-update period
- Specific pages show consistent ranking decline for 2+ consecutive weeks
- Competitors in the Polish market for the same queries have moved up permanently
- Action: Audit affected pages for E-E-A-T signals, content depth, and Polish-market relevance.

FAQ
Q: Is SERP volatility in Google.pl normal after the May 2026 Core Update ended? A: Yes. Post-rollout volatility lasting two to four weeks is standard. Google continues rescoring pages after the official end date. For May 2026 Core Update (ended June 2), expect stabilisation by end of June 2026.
Q: Our site serves both Polish and international audiences. Will the volatility affect both equally? A: Not necessarily. Polish-language and English-language pages are evaluated in their respective competitive sets. Volatility may differ between the two segments. Check GSC separately by language and country.
Q: Should international businesses in Poland act differently than local Polish sites after May 2026 Core Update? A: The response framework is the same: wait for stable data before making changes. The difference is in diagnostics - international sites competing in Google.pl should check if their position changes reflect local competitor gains rather than quality issues with their own content.
Q: What's the expected timeline for Google.pl ranking stabilisation after May 2026 Core Update? A: Based on patterns from previous Core Updates - first signs of stability by end of June 2026, full stabilisation by mid-July 2026.
Q: We noticed some competitors in Poland gained significantly. Is that a Core Update effect? A: It could be genuine Core Update impact on your competitors (their content was rewarded) or temporary volatility that will partially reverse. Wait until end of June before drawing conclusions about permanent competitive changes.
