One row per character. Required columns are slug, character, stroke_count, jlpt_level, and frequency_rank. Useful optional columns include onyomi list, kunyomi list, radical, mnemonic, stroke_order_svg, compounds JSON, English meaning, and related_slugs. SleekRank maps each column individually to its slot on the rendered page.

Yes. Store inline SVG per row in the stroke_order_svg column, generated from the KanjiVG database. The selector mapping injects the SVG into the rendered page, and CSS keyframe animation reveals strokes in sequence on hover or on a play button click. Each URL serves only its own SVG.

Store compounds as a JSON list of objects with the compound, the reading, the meaning, and the slugs of the kanji it contains. The list mapping iterates the array and renders one card per compound. Each card links to the relevant vocabulary page, and the constituent kanji link back to their own SleekRank URLs.

Google indexes pages it considers useful and crawlable. Kanji pages serve real reference value: readings, stroke order, JLPT level, frequency rank, compounds, and mnemonic. Each URL serves its own DefinedTerm schema and competes for its own character query rather than fighting siblings for an anchor on a parent page.

Yes. Add rows for jinmeiyo and other commonly-used non-joyo characters. The page renders identically, with the jlpt_level column showing none or jouyou-flag set to false. Extended kanji rows benefit from the same internal linking and structured data as the core joyo set, without bloating the base WordPress page.

Store related_slugs as a JSON list per row, grouping by shared radical, similar shape, or shared reading. The list mapping iterates the array and renders one card per related kanji. The reading and meaning preview on each card lets the learner browse related characters without leaving the URL family.

No. Each generated URL serves only its own inline SVG, not all 2,200. SVG is text-based and gzip-compressible, so the per-page weight stays well below the size of a single photo. The animation runs on CSS, which adds no JavaScript runtime cost and respects prefers-reduced-motion settings.

SleekRank writes a DefinedTerm schema block per row, including name, description, inLanguage set to ja, and url. The character itself appears in alternateName for ASCII-search compatibility. The meta mapping inserts the JSON-LD into the head, so Google can interpret the structured data alongside the rendered HTML.
