A major personal care brand faced a critical international SEO issue, where non-U.S. pages frequently appeared in U.S. search results, causing search cannibalization and confusing users.
Despite strong brand authority, the U.S. search landscape was cluttered with regional versions of the same product pages, leading to:

Misdirected users landing on non-relevant country pages instead of U.S. product pages.
🔍 Keyword dilution, where multiple international pages competed against each other for the same key terms.
📉 Drop in conversions as U.S. customers struggled to find the correct purchase page.

This issue stemmed from inconsistent hreflang implementation, causing Google to serve non-relevant pages in various search markets.
The site had multiple regional versions of the same content, each intended for different markets:

- US Pages – The primary versions intended for US audiences, correctly mapped with hreflang tags but losing visibility in search.
- Non-US Pages (UK, India, Canada, etc.) – Frequently more detailed, better optimized, and lacking proper hreflang connections back to US pages.

Despite correct hreflang implementation on US pages, the absence of reciprocal hreflang links and missing hreflang sitemaps on many regional sites led to search engines misattributing rankings, causing non-US versions to outrank US pages in US search results. This led to:

🔗 Broken hreflang reciprocity – While US pages linked to their international counterparts, non-US pages often failed to point back to the US version. This inconsistency confused Google, preventing it from correctly understanding which version should rank in which region.

🚫 Missing hreflang sitemaps – Some regional sites lacked an hreflang sitemap entirely, making it difficult for Google to associate the correct language and country variations. Without a structured sitemap, search engines relied on other ranking signals, leading to non-US pages appearing in US search results.

🌍 Stronger non-US content & US content limitations – Non-US teams, particularly in the UK, India, and Canada, created more detailed, optimized, and frequently updated content, giving them an advantage in rankings. However, the US content team resisted improving on-page content, believing it was already sufficient. While the hreflang mismatches were the immediate issue, long-term SEO stability required the US content team to enhance their pages to remain competitive.

⚠️ Lack of global team collaboration – Despite recognizing the issue, the US SEO team faced hesitation from international teams, who were either unwilling or slow to implement changes. This lack of cooperation further delayed fixes, prolonging the ranking disparities.

Since non-US pages were still valuable for their respective regions, we needed a solution that ensured US pages ranked properly in the US without negatively impacting global SEO. In the short term, fixing the hreflang sitemap mismatches was the priority, but long-term success required the US content team to improve content quality to remain competitive.
