TravelWise Case Study: SEO Audit Results

The Challenge

TravelWise is an online travel agency operating across 14 markets in Europe, Asia, and the Americas. Their site serves localized content in 11 languages with country-specific pricing, destination guides, and booking experiences. With over 25,000 pages per market, their total crawlable footprint exceeded 350,000 URLs.

Their international SEO was underperforming dramatically. Despite investing heavily in content localization, only their UK and US sites ranked well. Traffic from German, French, Japanese, and other markets had stagnated, and in several cases Google was serving the wrong language version to users — showing English results to German searchers and Japanese pages to users in France.

The root cause was a hreflang implementation that had broken down over time. When TravelWise launched their international sites, hreflang tags were implemented correctly. But as pages were added, removed, and restructured across markets at different paces, the bidirectional hreflang references fell out of sync. Pages referenced versions that no longer existed, return tags were missing, and several markets had circular references that confused search engines entirely.

Manual auditing of hreflang across 350,000 URLs was impractical. The team had attempted it twice, spending weeks building spreadsheets only to find that the data was outdated by the time they finished the audit. They needed continuous validation that could keep pace with their multi-market publishing schedule.

The Solution

TravelWise deployed Auditite with its international SEO module configured for all 14 market variants. The platform crawled each market version independently and then cross-referenced hreflang declarations across all versions simultaneously — something that would have been impossible to do manually at this scale.

The initial cross-market audit uncovered 8,400 hreflang errors. These fell into several categories: 3,200 missing return tags where page A referenced page B but page B did not reference page A back, 2,100 references to pages that had been deleted or redirected, 1,800 pages using incorrect language or region codes, and 1,300 pages missing hreflang tags entirely.

Auditite’s visual mapping tool showed the team exactly which market pairs had the most broken connections. The Germany-Japan and France-Brazil pairs had the highest error rates, correlating directly with the markets where traffic performance was weakest.

The team used Auditite’s bulk fix recommendations to generate corrected hreflang tag sets for each page. Rather than manually editing thousands of pages, they used the exported fix data to update their CMS template logic, ensuring that hreflang tags were dynamically generated from a single source of truth validated by Auditite.

They also configured ongoing monitoring with alerts for any new hreflang inconsistencies. This was critical because their content teams in different countries published on different schedules, and a new page in one market needed corresponding hreflang updates across all other markets.

The Results

The impact of fixing hreflang implementation was both rapid and substantial:

• International traffic grew 212% across all non-English markets combined over six months. The German market alone saw a 340% increase as Google began serving the correct language version consistently.
• 8,400+ hreflang errors were resolved, bringing the cross-market implementation to 99.7% accuracy. The remaining 0.3% represented pages in active development that were flagged for review before publication.
• All 14 markets achieved page-one rankings for their core destination queries in local search results. Previously, only 2 markets had consistent page-one presence.
• Bounce rate on international pages dropped 41%, as users now landed on pages in their own language with local pricing and locally relevant content.
• Booking conversions from organic search increased 156% across international markets, driven by the combination of correct language targeting and reduced bounce rates.

The SEO team reported that what had previously required weeks of manual spreadsheet work could now be validated in minutes through Auditite’s cross-market dashboard.

What’s Next

TravelWise is expanding into three additional markets — South Korea, Thailand, and Turkey — and plans to use Auditite’s international SEO monitoring from day one to ensure correct hreflang implementation before launch rather than fixing it retroactively.

They are also exploring Auditite’s content quality features to ensure that translated and localized content maintains the same SEO standards as their English originals, particularly around meta descriptions and heading structures that are often inconsistent across translations.

Elena Kowalski reflected on the transformation: “International SEO at scale is incredibly fragile. One broken hreflang tag can cascade across all your markets. Auditite gave us the confidence that our implementation is correct across 350,000 pages and 14 markets, every single day. That peace of mind is priceless.”
