The May 2026 Core Update concluded on 2 June. Significant SERP volatility continued through mid-June. For businesses serving Ukrainian audiences - whether operating in Ukraine, targeting the Ukrainian diaspora abroad, or running multilingual sites with Ukrainian traffic - the post-update instability affects different traffic segments in different ways.
Why Rankings Are Still Moving After May 2026 Core Update
Core Update completion marks the end of the algorithmic deployment, not the end of quality rescoring. Google continues processing pages for two to four weeks after the official end date. The volatility tracking tools reported through June 8-12 is the documented "second wave" - micro-corrections Google makes after assessing unintended effects of the main update.
For Ukrainian search traffic specifically, there are additional factors:
Google.com.ua versus google.com search patterns. Ukrainian users access Google through multiple entry points. Ranking dynamics in Google's Ukrainian-localised results can differ from global results, particularly for informational and local-intent queries.
Post-2022 search behaviour shifts. Ukrainian online audiences have shifted significantly in terms of content consumption, language preference, and search behaviour since 2022. Sites that haven't updated their content strategy to reflect current Ukrainian search intent may see amplified Core Update effects.
Mixed-language sites. If your site has Ukrainian, Russian, and English content, Google evaluates each language version in its competitive set. Volatility may differ significantly across language versions.
Framework for Ukrainian-Market Traffic Assessment
Open GSC → Performance → filter Country: Ukraine. Compare four-week periods before and after June 2 (the Core Update end date).
Volatility pattern:
- Ukraine traffic within 15% of pre-update baseline
- Positions oscillate without a consistent downward trend
- Multiple keyword types affected simultaneously
Genuine impact pattern:
- Ukraine traffic down 20%+ compared to equivalent pre-update period
- Specific informational or commercial queries show consistent weekly position loss
- Ukrainian-language pages affected more than other language versions
Specific Considerations for IT and SaaS Companies With Ukrainian Audience
Ukraine has a significant IT and SaaS sector with both local and international user bases. For English-language SaaS and tech sites targeting Ukrainian users:
The May 2026 Core Update placed stronger emphasis on E-E-A-T signals for software and service review content. If your site has Ukrainian-market landing pages or blog content that was thin on demonstrated expertise, these pages may have experienced genuine (not just volatile) ranking changes.

FAQ
Q: Is ranking volatility after May 2026 Core Update affecting Ukrainian market searches specifically? A: Yes, but it's not unique to Ukraine. All national search markets are experiencing the same post-rollout volatility pattern. The May 2026 Core Update's effects are market-wide, not geography-specific.
Q: Our site gets traffic from both Ukrainian and EU audiences. Which segment is more volatile right now? A: Both are subject to the same post-update volatility. Check GSC separately for each country segment to see if the patterns differ. Sometimes Core Updates affect different national markets at slightly different paces.
Q: When will Google rankings for Ukrainian search terms stabilise after May 2026 Core Update? A: Based on historical patterns - first stability signals by end of June 2026, full stabilisation by mid-July 2026.
Q: We run a Ukrainian-language blog and an English-language blog on the same domain. Both are volatile - is this the Core Update? A: It could be. If both language versions are volatile simultaneously, it may reflect domain-level rescoring rather than page-level changes. Wait until end of June for stable data before drawing conclusions about which language version is genuinely affected.
Q: Should we invest in new Ukrainian-market content creation during this volatile period? A: Yes - creating new content is fine during the post-update period. What to avoid is changing existing content or restructuring pages that are currently ranking, as that can extend instability on those specific pages.
