TextCortex

TextCortex, an AI agent platform, empowers users to create high-quality content at scale using advanced language models. With organic search traffic and global market penetration driving their growth strategy, TextCortex recognized a critical opportunity: optimizing their website for international audiences through strategic localization.

Operating with a primarily English website while serving a diverse global user base, the team knew they were leaving significant traffic and conversions on the table from non-English speaking markets.

Since organic traffic—both traditional and now AI search—is fundamental to their customer acquisition, expanding with a translated website was essential for capturing the full potential of their international audience.

Evolving Into an AI Platform with True Global Reach

Despite offering cutting-edge AI technology, TextCortex found itself constrained by limited international visibility. With search engine performance critical to their business model, they were facing two major challenges that were hindering their global expansion:

• Limited search engine visibility in local markets
• Traffic attribution issues from Google Translate redirects

"As Google prioritizes localized content more aggressively, we needed a solution that would help us rank higher, easier and faster in international markets."

The team understood that in the evolving landscape of AI search and LLM visibility, having properly localized content was no longer a nice-to-have but an essential. With LLMs like ChatGPT and others increasingly relying on search engines for information, TextCortex needed to ensure its content was discoverable not just through traditional search, but also through emerging AI-powered search tools.

That's what led them to Weglot over 3 years ago.

Weglot offered exactly what TextCortex needed: multilingual SEO best practices built-in, automatic structured data translation, and the ability to have native localized pages that would rank effectively in their respective markets. Plus, Weglot's tone of voice setting and Glossary options were perfect for handling TextCortex's specialized AI and technical terminology.

A Partnership Built on Excellence

“I'm a big fan of Weglot; it’s been 3 years since we started using it. We're happy customers.”

After more than 3 years as a Weglot customer, TextCortex has consistently praised the partnership for its seamless experience and exceptional support quality. The team particularly values several key aspects that made Weglot the ideal choice for their business:

Top-Tier Customer Support: The responsiveness and quality of Weglot's support team has been a standout feature, providing immediate assistance whenever technical questions arise and ensuring minimal disruption to TextCortex's operations.

“You also have a top-tier customer support...The response time is so fast, which is insanely good quality.”

Custom Glossary for AI Terminology: As an AI agent platform, TextCortex deals with specialized technical terms that need precise translation. Weglot's Glossary feature lets them define exactly how specific terms should be translated, ensuring accuracy and consistency across all languages.

Addressing Language Formality Challenge: TextCortex identified a previous pain point around configuring language formality—particularly crucial in languages like German, where formal/informal distinctions significantly impact user experience. The formal tone can make content feel bureaucratic and distant, while informal language creates a more approachable, user-friendly experience. Weglot's custom AI Language Model fixed that issue, including prompts for informal/formal translations. It directly addressed this challenge, giving TextCortex the control they needed to set the right tone for their audience in each language.

SEO-First Architecture: Weglot's automatic handling of structured data translation and multilingual SEO best practices meant TextCortex could expand internationally without sacrificing search performance. The tool automatically manages hreflang implementation and creates properly optimized localized pages.

Today, TextCortex operates with multiple languages including Spanish, French, Italian, Portuguese, German, and Dutch, with each market contributing significantly to their overall traffic and engagement metrics.

From English-Only to Global Powerhouse: TextCortex's Traffic Transformation

"Most of our traffic comes from localized pages thanks to Weglot. It's in the millions."

Since adding Weglot, the impact on TextCortex's international website traffic has been significant.

• 77.81% of all traffic now lands on localized pages (Spanish, French, Italian, Portuguese, German, Dutch, etc.)
• Only 22.19% visit English pages (mostly from the US, UK, India)

These localized markets align perfectly with TextCortex's strongest operational presence and highest-quality lead generation

A closer look at the German market further shows the power of a translated website:

• 56.23% engagement rate (the highest across all languages)
• 6 minutes 15 seconds average session duration (the longest)
• Significantly outperforming English pages: 53.87% engagement rate with 3m 55s session duration

Weglot has significantly boosted TextCortex's organic traffic, particularly in Italian, German, and French markets. This has proven especially valuable as:

• Google's recent core updates increasingly prioritize localized pages in local searches
• LLM visibility is indirectly improved through better SEO rankings
• Tools like ExaSearch and Serper API, which are used by LLMs, still depend on traditional search engine results
• Localized pages consistently rank higher in their respective markets
