TDQS
Scored across 13 tools
Each tool targets a distinct output (a specific ad metric, a text-analysis task, or a specific tag/file type), so most are clearly separable. There is mild overlap among the meta-tag-producing tools (open_graph_generator, hreflang_generator, meta_tag_generator, schema_markup_generator), but descriptions make the boundaries clear enough.
Nearly all names follow a consistent snake_case <subject>_<role> pattern with predictable suffixes (_calculator, _generator, _counter, _analyzer). The lone deviation is keyword_density, which uses the metric name rather than an action suffix, but overall it is highly readable and consistent.
13 tools is well within the ideal range and each one covers a distinct SEO/marketing utility. No redundant or filler tools are apparent; each earns its place.
The surface covers the main SEO/web toolkit areas: ad metrics, content analysis, and tag/file generators (meta, OG, hreflang, schema, sitemap, robots). Minor gaps exist (e.g. no SERP/preview or image-alt tooling), but core workflows are covered with no obvious dead ends.
