At a glanceWe launched Citera, a Shopify theme developed for technical SEO, structured data, accessibility and brand documentation for AI interfaces. It includes JSON-LD, editorial control for llms.txt and agents.md, IndexNow and CRO components without fabricated data. These features support technical clarity but do not guarantee indexing or citation by an AI search engine. Live on atadesaci.ro.
The way people search for products is changing. Some shoppers now ask ChatGPT, Perplexity, Gemini, Copilot or Google AI Mode directly instead of opening ten Google results: "What is the best supplement for memory?", "Which brand of X would you recommend?". A store needs clear, accessible and verifiable information to support discovery and citation in these answers.
Many stores were not designed with this kind of search in mind. The foundation remains the same as good SEO: useful content, semantic HTML, structured data matching the page and consistent commercial information. Dedicated AI files can add documentation, but do not replace this foundation or guarantee citations.
That is why we built Citera, a premium Shopify theme integrating this foundation at theme level. The store starts with semantic structure, structured data, SEO controls and editorial information for AI systems, without requiring multiple separate apps for these core features.
The current problem and Citera's approach
Some present "AI optimisation" as a shortcut: place an llms.txt file in the site root and the job is done. The reality in 2026 is more nuanced, and the theme is built around technical foundations.
Schema.org structured data in JSON-LD format and semantic HTML help search engines interpret pages. Price, availability, specifications and frequently asked questions must match the visible information. This is a useful technical foundation, not a promise of rankings or citations.
Alongside this, llms.txt and agents.md can provide documentation for AI agents acting on behalf of users, where those systems support it. Orders attributed to AI channels should be measured separately in analytics and compared with other traffic over the same period.
Citera provides both: structured data for store products and content, and editable llms.txt / llms-full.txt / agents.md information for systems that use it. The benefit is integration within the theme rather than relying on a standalone plugin.
Some plugins require a monthly subscription and additional resources. Citera provides these functions natively at theme level, without a separate recurring plugin fee or additional plugin code for those features.
Theme features, one by one
Citera combines technical SEO, speed and accessibility with features designed to help shoppers convert and provide AI systems with the same accurate information. Here is what it includes.
The theme generates a valid JSON-LD graph while avoiding duplication of data already injected by Shopify, which the source identifies as a review concern. It covers: Product with a complete Offer: name, images, SKU, brand, GTIN/MPN, price, currency, availability, aggregate rating, and shipping and returns from metafields; BreadcrumbList on collections and products; Organization + WebSite with a search action; FAQPage, CollectionPage / ItemList for catalogue listings; and Article / BlogPosting with speakable.
A consistent heading hierarchy, a single h1and consistent rich-text output. Two additional blocks summarise information for readers: "Key facts" (a short factual list) and FAQ (real questions that also populate FAQPage schema).
llms.txt, llms-full.txt and agents.md editableAn "AI & Agents" settings group with text areas for each file, plus defaults composed from the store name, main collections, policies and contact information. Edit once in the Theme Editor to update the relevant pages. The manual step is a one-line redirect for the canonical path /llms.txt, documented clearly or configured by us during installation.
Technical support for search engines, including Google, Bing, Yahoo and Yandex: the native sitemap is retained, with a field for an IndexNow key to notify supporting search engines of changes, clean canonicals, meta title/description defaults, Open Graph, Twitter cards and hreflang for multilingual stores. A dedicated control is provided for AI crawlers such as GPTBot, ClaudeBot and PerplexityBot.
Meta title/description templates with tokens for store, product, collection, price and vendor; canonical control; global title prefix/suffix; noindex switches for thin pages such as search, cart and tags; and a fallback social image. These technical SEO settings are managed without a separate SEO app.
One place to add supported code without editing theme.liquid: verification tags for Google Search Console, Bing/Yahoo, Yandex and Pinterest, an IndexNow key, behaviour and analytics tools such as Microsoft Clarity, Hotjar, GA4, Meta Pixel and TikTok Pixel, plus optional custom snippet fields.
A library of native conversion modules that can be enabled or disabled and do not add external scripts: free-shipping progress bar, urgency tied to actual stock and promotion end dates, trust sections, sticky Add to Cart bar, quick-add / quick-view, recommendations through Shopify's native API, Frequently Bought Together with combined pricing, volume discounts applied through Shopify, automatic free gift above a threshold, announcement bar, AJAX cart and back-in-stock hooks.
Every displayed figure comes from actual data: inventory, orders, promotion end dates and reviews. No invented "X people are viewing", fabricated "12 sold today", endless countdowns or fake reviews. This protects brand credibility, reduces misleading-pattern concerns and keeps the structured data provided to search and AI systems consistent with reality.

Built on Skeleton for Shopify theme requirements
Citera was built from scratch on Skeleton, the base code the source identifies as Shopify-approved for new Theme Store submissions after 15 May 2025. The source states that Dawn- or Horizon-derived themes are not eligible under that requirement. The code is original and the visual design targets modern D2C brands driven by discovery: supplements, wellness, gadgets, home and beauty. This describes the development approach, not approval by the Shopify Theme Store.
