One set of core content. A version for every channel.
Marketplaces publish product page guidelines that run to a hundred pages per category, and most say the same thing early on: don't send us the copy you post everywhere else. Channel Optimization uses AI to turn your core product content into a channel-specific version, field by field, following that channel's guideline for that product category. That version is what wins the buy box, earns the supplier score, and surfaces when shoppers search.
Every field can be seen through the lens of a channel.
Most product systems handle channel-specific copy by adding fields: description_amazon, description_walmart, title_homedepot, and on it goes until the schema is unreadable. Syndic8 does it differently. Any field can carry a channel version. Set one for Amazon and Amazon gets it. Leave it empty and your core content flows through. Flip the same product to Walmart and you see Walmart's versions, or none.
Why the channels demand it
Walmart's guideline asks for wording "unique to Walmart.com, not reused among other online retailers," and lists copy reused across sites as prohibited. Marketplaces don't want to index the same paragraph they can find on your site and on four competitors' listings. Unique, guideline-shaped content is how a listing earns placement.
Why your core stays clean
Your core content is yours: the version you own and maintain in one place. Optimization writes channel versions beside it, never over it. If a channel changes its rules, you regenerate that version and nothing else moves.
Why it's field-level
A title needs a different formula on every channel; a materials attribute probably doesn't. You optimize the fields that matter for that channel and let the rest pass through, so there's less to review and less to drift.
Rules a person had to apply by hand until this year.
Filling the template was the old problem: short description mandatory, 64 characters minimum. Everyone solved that. The new problem is the guideline on top of the template: per-category formulas and preferences that decide whether a listing sells. A few examples of what the AI is working from:
Amazon: brand, style, product type, key attribute, color, size, model number, in that order, no word more than twice. Walmart tires: Brand + Season + Size + Load Index + Speed Rating + "Tire", inside 90 characters.
Amazon: header, colon, description, every bullet unique. Walmart: three to ten, 80 characters each, most important first. Most catalogs have decent bullets; they need reordering, and usually more of them.
Walmart: 150 words minimum, product name once, no "free shipping" or "best-selling", no "Amazon exclusive". Amazon: no price, delivery or reviews, and no "eco-friendly" without proof.
Amazon: 250 bytes, lowercase, no words already in the title, singular or plural but not both. Walmart: no backend field at all, so the keywords have to live in the title and key features.
Which feature is most important, whether a claim is promotional, whether a bullet repeats the title: none of this is a pattern match. It's judgment, and until recently it meant a person who had read the whole guideline. The AI in Syndic8 has read it, for every channel and category Syndic8 maintains, and applies it the same way to SKU 1 and SKU 10,000.
The channel's rules come first. Your voice shapes the wording inside them.
Everything below is optional. Set any of it once and every optimization run uses it, whether you launch the run from the product page or by telling Syndic8 Copilot to optimize a SKU or a whole collection for a channel. Either way, you see the proposed changes beside the current values and approve them before anything is saved.
Audience and persona
Write for homeowners 30 to 55, or for contractors, or for gift buyers. Give it a style or persona and it holds across the whole collection.
Words to use and words to avoid
Ban the trademarked term ("Velcro" when you mean hook-and-loop). Ask it to include the terms your buyers search for, where the channel allows them.
Your whole brand guideline
Paste it in, all forty pages, once. It stays attached, so every person and every brand in the account writes the same way.
Language versions
A field or a whole product rendered in Mexican Spanish rather than Castilian, as a channel version, so you stop paying per word for translation that doesn't know your products.
Pick a product line and a channel. We'll show you the before and after.
Send a product file, or point us at your current listings. You'll get the channel versions the AI proposes, with the guideline rule behind every change, before you commit to anything.
