A: Hi,
Thanks for the detailed feedback, this is useful.
On the H3 issue: this would help me to have an example URL where this happens. If H3 tags are present but not detected, it could be a real bug worth fixing quickly, or it could be related to how they're generated (loaded after page render, or non-standard markup). Either way, I'd rather check a concrete case than guess.
On singular/plural and word splitting: the semantic analysis works at the term level, and detecting inflected forms (plural, declension) is genuinely harder in German than in English or French due to compound words and grammatical cases. This is an area I know can be improved, and German-specific handling is something I want to refine further.
On search volume showing 0 while Search Console shows thousands: this is expected, though I understand it's confusing. The volume figures come from a third-party API (DataForSEO), which uses its own estimation methodology, different from Google Search Console's actual impression data. These are aggregate estimates, not a live reflection of your specific rankings or impressions, so discrepancies with GSC are common across all tools relying on this kind of data, not just Textfocus.
On free credits: yes, they're intentionally limited, and only a partial view of results is shown in the free tier. That's a deliberate constraint to keep the model sustainable, but I understand it makes a full evaluation harder upfront.
If you can share an example page (ideally German e-commerce, long-form), I'm happy to look at the H3 detection and the semantic output specifically for that case. Feedback from agency users working in non-English languages is exactly what helps me prioritize the right fixes.
