Version history

Fixed

• Converted four absolute non-www internal links in the double-penetration entry to relative paths, matching the convention used by every other entry — removing a mixed www/non-www signal that could slow search-engine URL consolidation.

Added

• New homepage section, “Meet our collections,” previewing the eight collections with the most entries as image-led plates (emblem, title, tagline, entry count), with a “See all collections” link through to /collections.
• Entry detail pages now carry a “Featured in” strip showing every curated collection the entry belongs to — each an emblem-led card (graphite art, title, tagline, entry count) linking through to the collection, giving readers a cross-cutting way to explore related interests.

Changed

• Every support page (browse, categories, collections, about, methodology, changelog) now ships complete, unique SEO metadata via a shared pageMeta() helper — keyword-rich titles, per-page Open Graph and Twitter cards, canonical URLs, and an explicit share image — instead of inheriting the homepage's social card.
• Added JSON-LD structured data to the methodology and changelog pages for parity with the rest of the site.

Content

• Added five entries surfaced by the kinksheet.com audit: Anal Play (umbrella for anal stimulation), Double Penetration, Incest Fantasy (consensual-adult pseudo-incest roleplay — actual incest is illegal and out of scope), Barebacking (with neutral STI/HIV/PrEP harm-reduction framing) and Clothed Sex (CFNM / CMNF).
• Added the two remaining coverage-diff gaps: Gynephilia (a non-pathological sexological descriptor for attraction to women) under Identity & Transformation, and Hell & Damnation Fetish (Stygiophilia) under Clinical Paraphilias.
• All seven entries ship with baked SEO, version-busted graphite artwork, and verified clinical, non-explicit prose; the catalog now stands at 389 entries with full coverage against kinksheet.com and the A–Z/Wikipedia source lists.

Content

• Added Cheek Fetish (Buccalagnia), Dimple Fetish (Erogonophilia) and Tail Fetish (Caudaphilia) under Body Parts & Partialism — the three entries that were absent versus Wikipedia's partialism “Types” table.

Fixed

• Search now puts the entry whose title matches your query first. Previously every “… Fetish” entry tied on Fuse's score for a query ending in “fetish”, so the intended result (e.g. “Tail Fetish”) could be buried beneath more-popular but unrelated matches; a title-dominance re-rank (exact title › title prefix › clinical synonym › title word) fixes this while keeping fuzzy infix search (“onda” still finds “Bondage”).

Changed

• Entry page titles now follow “Name (Clinical Synonym): Meaning, Definition & Examples”, dropping the near-zero-search “prevalence” for descriptors that match how people actually search (“X meaning”, “what is X”, “X examples”).
• Category pages now open with the same header as collection pages — a “Back to categories” link, the same emblem size, and an entry count — for a consistent feel across the two.

Added

• “Collections” now appears in the main navigation, right after Categories.

Fixed

• Title length now accounts for the “ · KINKSpec” brand suffix, so titles no longer truncate in search results (110 entries previously overflowed 60 characters; now none do).
• Fixed a duplicated clinical name in a few titles (e.g. “Transvestic Disorder (Transvestic Disorder (…))”).

Added

• Twelve new entries: Barefoot Fetish, Sole Fetish, Arch Fetish, Footjob, Foot Worship, Toe Sucking, Foot Domination, Trampling, Foot Odor Fetish, Bootblacking, Shoeplay and Sole Licking — each with a deep, cited article, popularity index, original graphite illustration and SEO metadata.
• All twelve join the Foot Fetish collection (now 25 entries); Foot Worship, Foot Domination, Trampling and Bootblacking also join the BDSM collection.

Added

• Each collection page now has a dynamic 1200×630 Open Graph image (title, tagline, description and the collection's emblem on the brand-gold card), so links shared to social and chat apps render a proper preview instead of a generic fallback.

Added

• Twelve new collections targeting the highest-traffic kink & fetish search niches, each with an SEO-optimized title, description and keyword set, and structured data: BDSM, Foot Fetish & Feet, Pet Play, Age Play/DDLG & Littles, Cuckolding & Hotwife, Lingerie & Underwear, Latex/Leather & Rubber, Roleplay & Scenario Fantasies, Voyeurism & Exhibitionism, Chastity & Orgasm Control, Feminization & Sissy Play, and Furry & Anthro.
• Entries can now belong to several collections at once, so a term like Maid Fetish appears under both Roleplay and Feminization — letting each collection group the genuinely relevant entries without duplication.
• Original graphite emblems generated for all twelve new collections.

Fixed

• Listing grids and cards now cache-bust regenerated artwork with a content-hash in the image URL — the same fix the detail page already had — so an updated illustration can no longer show a stale, cached version in collection, category, browse or homepage grids.

Changed

• Refined several illustrations for accuracy: Stocking and Nylon fetishes now render as full-length sheer hosiery instead of a short sock; Bastinado (foot-whipping) now shows the foot together with the cane; Shoe Fetish is now an elegant flat, visually distinct from High Heel Fetish; and the Foot Fetish collection emblem is now a poised foot in an open-toe heel.

Changed

• Homepage title is now “List of Kinks & Fetishes: 350+ Defined & Ranked | KINKSpec” — leads with the exact head query and the “List” intent word every ranking competitor uses, adds a catalog count, surfaces the unique 0–100 ranking, and moves the brand to the end.
• Meta description now opens with “An A–Z list of 350+ kinks, fetishes & paraphilias…” instead of the brand name, front-loading the keywords for better relevance and click-through.

Added

• Permanent redirect from /sitemap to /sitemap.xml, so a guessed or hand-typed /sitemap lands on the actual sitemap.

Added

• /llms.txt now lists every Collection (title, link, tagline) as a second thematic index, and links the /categories and /collections landing pages from its Reference section.
• /llms-full.txt now inlines each Collection with its description, canonical URL, and every member entry, so an answer engine can cite a grouping and follow through to each term in it.

Added

• New /categories page listing every kink & fetish category with an SEO-optimized headline, description, and structured data — linked from the homepage, header, footer and sitemap.
• Graphite emblem for the “Fantasy, Fiction & Fandom” collection, shown on the collections list and detail page.
• Original graphite illustrations for the 17 remaining un-illustrated entries — every entry now has artwork.

Changed

• Homepage category section retitled “Browse kinks & fetishes by category” with a keyword-rich description, now previewing the eight most-documented categories (“See all categories →” opens the full list).
• Collection emblem prompts now flow through the shared image policy, so entries, categories and collections share one clean-background, no-text house style that can no longer drift.

Fixed

• Regenerated images (same filename) now carry a content-hash in their URL, so browsers and the CDN always pick up the new artwork instead of a stale cached copy.

Changed

• Refined the collection page layout — a “Back to collections” link, the title and description set beside the emblem, a consistent 4:5 emblem (matching the entry plates) that opens in a lightbox, and unified emblem sizing across the collections index and detail.

Content

• Added 17 new entries covering anime, manga and fandom-rooted interests — futanari, fictosexuality, monster girl, kemonomimi, scalie, werewolf and succubus attraction, mermaid, VTuber attraction, ahegao, yandere, the dere archetypes, nyotaimori, zentai, dronification, otherkin and spectrosexuality — each a web-verified article. They join the “Fantasy, Fiction & Fandom” collection, now 39 entries (the catalog is up to 367).

Added

• New “Collections” section at /collections: curated, cross-cutting groupings that gather related interests across the catalog’s categories. The first collection, “Fantasy, Fiction & Fandom,” brings together anime and manga tropes, fantasy creatures, transformation, cosplay and online-subculture interests in one place. More collections to come.

Changed

• Added automated quality gates — data validation on every build plus continuous-integration checks — so malformed entries, over-length text, or mis-configured images can no longer ship unnoticed (the class of issue that briefly affected a couple of pages this week).
• Internal tidy-up: a single source of truth for image quality and the catalog data shape, archived one-off scripts, and removed unused dependencies. No change to how the site looks or reads.

Changed

• Each entry now publishes its prevalence and 0–100 popularity figures as machine-readable structured data, and is marked up as a medical reference page reviewed by KINKSpec — helping search engines and AI assistants quote the numbers and cite the right page.

Fixed

• The homepage 'Browse by category' emblems and the 'Most common' plates could render blank after the previous release; their images now load correctly again.

Content

• Rewrote the twenty most searched interests (dominance and submission, bondage, spanking, masturbation, exhibitionism, masochism and more) to reference grade: deeper and properly dated histories, more cited sources, and additional cross-links to related entries.

Changed

• Hardened the site with modern security response headers (Content-Security-Policy, HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy and Permissions-Policy), following current web best practice.
• Entries documenting harmful or illegal topics (kept only for clinical completeness) are now withheld from search-engine indexes, the sitemap, the AI-crawler feeds (llms.txt) and the glossary's structured data. They stay reachable through browse and search on the site itself.

Fixed

• Trimmed the furry fandom summary so it sits within the catalog's length limit.

Content

• Rewrote the punctuation across every entry and category: roughly 8,500 em dashes — a hallmark of machine-written text — are now natural commas, colons and parentheses, so the writing reads as a human editor wrote it.
• Renamed the “Hybristophilia” entry to its common name, “Attraction to Criminals” (the clinical term stays as a subtitle); the old link redirects to the new one.

Changed

• On the index and category pages, the filter controls now stay in view as you scroll — the search box scrolls away, and the bar sits just below the header rather than flush against it.

Changed

• 'Browse by category' on the homepage is now an image-led gallery — each of the eleven families shown as its graphite emblem above its name, replacing the proportion-bar chart. The size distribution still lives in 'The distribution' section above.
• 'Most common kinks & fetishes' (formerly 'Most documented') now shows the highest-ranked interests as their own illustrations rather than text rows.
• The catalog — the index and every category page — now opens in the image grid by default; switch to the list view any time and your choice is remembered.

Added

• The category's graphite emblem now appears beside the heading on desktop — click it to enlarge, exactly like an entry's illustration.

Changed

• Moved the prevalence distribution down beside the overview, and removed the related-categories and subcategories blocks for a calmer, more focused page.

Added

• A hand-drawn graphite emblem for each of the 11 categories — a tasteful symbolic still-life that captures the theme (a balance scale and key for power dynamics, theatrical masks for identity, a glass of water for body fluids) — now bleeds down the right edge of every category share card, matching the entry cards.

Changed

• Category share cards now lead with the category's tagline and its full description, and drop the entry count for a cleaner layout.

Changed

• Rewrote every entry's search title and meta description: titles no longer repeat the clinical name or overflow the search result, and descriptions now read as complete sentences instead of being cut off mid-word.
• Every entry now shows related entries, even the few that had none authored — the page fills in the nearest interests from the same category, so no entry is a dead end.

Changed

• Search opens fullscreen on phones, with a clear close button; the keyboard hints and the per-row rank number (desktop-only details) are hidden on mobile so the focus stays on the entries themselves.
• Entry lists across the site (home, index, categories, related) drop the leading rank number on phones for a cleaner, item-first row.
• About page on mobile: tighter spacing, a smaller pull-quote, the illustration wall now shows two clean columns like the homepage, and the author bio is lighter — a small portrait with the name beside it, no card frame.
• Removed the divider lines and trimmed the spacing between sections on the homepage and methodology page on mobile.
• Footer colophon simplified to copyright on the left and version on the right.
• Swapped the homepage hero buttons so “Browse the index” comes first.

Fixed

• Fixed the methodology scoring formula overflowing the screen on mobile — it now fits the card cleanly.

Changed

• Redesigned the share cards (home, every entry and category) on the site's own look: warm-white background, the real KINKSpec lockup in Inter Tight (heavy KINK + lighter Spec) with the black-and-gold pictogram, dark ink text for readability, and gold kept as the accent (the pictogram ring and the popularity bar).
• The entry illustration now bleeds full-height down the right half of the card with a soft fade — no frame, no rounded corners.
• The home card now carries the homepage headline — “A clinical index of kinks & fetishes” with the gold highlight — and the live catalog summary (count of interests and categories).
• Entry cards show a fuller, three-line definition; long descriptions clamp cleanly with an ellipsis.

Fixed

• Share-card and canonical URLs now point at the correct host per environment — localhost in local development, the live www.kinkspec.com in production — instead of always hard-coding the live domain.

Changed

• Converted the entire illustration library to optimised WebP — the source plates dropped from ~405MB to ~26MB (−94%) with no visible quality loss, for far faster loads and cheaper image delivery.
• Self-hosted the fonts at latin-only subsets and preloaded the primary face, trimming unused character sets and steadying first paint.

Added

• Published /llms.txt and /llms-full.txt — clean, machine-readable maps of the whole catalog for AI answer engines (ChatGPT, Perplexity, Claude, Google AI Overviews), each with an explicit citation & attribution policy (cite KINKSpec, link the exact entry, use the canonical www URL).
• Explicitly welcomed AI crawlers in robots.txt, since KINKSpec wants to be cited accurately.
• Enriched structured data: every term now exposes all of its aliases and clinical name, a richer multi-question FAQ (definition, clinical name, prevalence, status), cited sources, a canonical glossary of all 350 terms, and a sitelinks search box.
• Added an image sitemap so the 350 plates are discoverable in Google Images.
• Anchored entry section headings so specific passages can be linked and cited directly.

Fixed

• Aligned every canonical URL, sitemap entry, structured-data link and share URL to the live www.kinkspec.com host (the apex now redirects there), so search and AI engines are never pointed at a redirect.
• Social/share cards now use the full, branded title and reliably include the generated preview image.
• Entry pages preload only the one illustration that's actually visible, improving the largest-content load time on phones.
• Hardened all structured-data output against markup-breaking characters.
• New illustrations are now optimised to WebP automatically as they're generated, so the library stays small.

Fixed

• Replaced the public/images → data/images symlink with a build-time copy. The symlink broke the production build on Vercel (“Cannot copy … to a subdirectory of itself”); a plain copy avoids it while still serving images from /images.
• Kept the ~400MB of source plates (data/images) out of serverless functions via output-file-tracing excludes. Next was bundling the whole folder into every function (lib/data lists it), which blew the 300MB function limit (“_not-found is 425MB”). The images are served statically from /images and embedded into OG cards at build time, so no runtime function needs them.

Fixed

• Republished the site so the mobile rework across the homepage, navigation, category and entry pages, and footer is live in production.

Changed

• On phones the entry page now opens with a full-bleed illustration (tap-to-zoom off) carrying the back and share controls over a soft gold wash, with the title beneath it set in the gold brand highlight that echoes the homepage. Larger screens keep the breadcrumb, the reading-column title, and the side plate.
• Dropped the divider above the Popularity Index and shrank the “higher than N%” line on phones.
• Folded the supporting detail into accordions at the foot on phones — Related entries (open) first, then Etymology, Tags, Measurement and Estimated prevalence, with Sources last; the dense “Where it sits” swarm is omitted on phones. Larger screens keep the full sections.
• Moved Classification into an accordion directly under the description on phones — carrying the prevalence, domain, confidence, clinical term and dates that the header normally shows, with confidence written plainly rather than as a tooltip.
• Tightened the measurement subscores on phones (the score now sits on the label row) and trimmed the empty space beneath the foot accordions.
• Reworked the footer on phones: the brand and links are left-aligned again, and the Categories and Index columns collapse into accordions.

Fixed

• Removed the clinical term that was duplicated in eight entry titles (e.g. “Attraction to Trans Women (Gynandromorphophilia)” → “Attraction to Trans Women”), since it already appears as the clinical name.

Added

• A fullscreen filter sheet on phones — opened from a filter icon next to the search box — with category and subcategory selects, type and sort segments, and a hide-notices toggle, plus a live “Show N entries” button. The filter icon carries a badge with the active-filter count.

Changed

• On phones the category page collapses into a compact Overview + Prevalence accordion, hiding the Related categories and Subcategories rails (which return as normal sections from the small breakpoint up).
• The category toolbar no longer sticks on phones — filtering happens in the sheet — while staying sticky on larger screens.
• Hid the “Entries by index” swarm on phones, matching the homepage.

Changed

• Mobile menu is now a full-screen takeover (pinned to the dynamic viewport height) and carries the dark/light toggle, which moved out of the phone header into the menu's footer rail.
• Homepage hero actions (Search / Browse) now sit side by side on phones, and buttons are smaller site-wide.
• Homepage stats render as a compact 2-column grid with smaller figures on phones.
• Renamed the categories section to “Browse by category”, and on phones it's now a compact list (code · name · count · proportion bar) instead of a tall stack of cards.
• Hid the dense “Every entry, plotted” swarm on phones, where it's unreadable and hover/zoom doesn't apply.
• Tightened the entry rows on phones — smaller rank/title, the index moved inline beside the name, the definition hidden, and reduced padding — and trimmed the homepage section spacing, dropping the divider above “Most documented”.
• Centered the footer on phones and tightened its spacing, so it reads as intentional rather than a stretched desktop layout.

Fixed

• Stopped the full-screen mobile menu from spilling past the right edge of the screen — the page's containing block is now pinned to the viewport (overflow-clip on the root), so fixed overlays can't stretch wider than the device.

Added

• Hamburger menu on phones — a drop-down panel beneath the header surfaces the Index, About, Methodology and Changelog links that the inline nav hides below 640px. Closes on a link tap, a backdrop tap, Escape, or when the viewport grows past the breakpoint; body scroll locks while it's open.

Changed

• Aligned the homepage hero's horizontal padding with the header and the sections below, so content edges line up on mobile.
• Hid the ⌘K hint on the hero search button at touch widths, where it doesn't apply.

Fixed

• Guarded against incidental horizontal scroll on small screens via overflow-clip on the page body.

Added

• A 'Subcategories' stat in the category header, alongside the existing 'Content notices' count.
• A subcategory filter on category pages — narrow entries by their facet within the family, with live counts.

Changed

• Converted the domain (All / Sexual / Non-sexual) and sort controls from segmented toggles to compact dropdown selects, with icons on the sort options.
• Reordered the filter toolbar to category → subcategory → domain.
• Refactored the category picker into a brand-aligned overlay: a header that matches the site masthead 1:1, with tighter padding and no bottom nav.

Content

• Rewrote every entry's long-form article to reference grade: a deep, chronological History & origins section with dated milestones, the people who first documented each interest, and the DSM / ICD lineage.
• Wove inline source citations through the prose and added internal cross-links between related entries.
• Refined every entry's short description and etymology, and expanded the list of cited sources behind each one.

Added

• This Version history page, linked from the footer — every change we deliberately ship is logged here from now on.

Changed

• Entry-detail header: the clinical name and the Added / Updated dates now sit together on one line, separated by a middot, instead of stacking.

Content

• Added 17 entries surfaced by a technical-name coverage audit, bringing the catalog to 350.

Added

• An image lightbox on entry pages — click an illustration to enlarge it.
• Added / Updated dates on every entry.

Changed

• Switched search to Fuse.js fuzzy matching, so partial and misspelled queries still resolve (e.g. “onda” → Bondage).

Added

• About and Methodology pages documenting how every entry is defined, classified, and scored.
• The 0–100 popularity index, five-signal scoring, and plain-language prevalence tiers.

Changed

• Rebranded to KINKSpec with a new monochromatic Geist design system, logo, favicon, and dynamic social cards.

Added

• Catalogued 246 sexual and non-sexual interests across 11 categories, each written as a neutral, clinical article with cited sources.
• The Next.js reference site: browse, category pages, and per-entry detail.
