WP Classifieds-style plugins store each listing as a custom post type (commonly classified or ad) and attach a category taxonomy plus per-listing meta in wp_postmeta. Typical keys include ad_price, ad_location, ad_expiry_date, ad_contact_email, and ad_phone. Ads usually carry an expiry timestamp that hides them automatically once passed.

SleekAI maps the listing post type, the category taxonomy, and the price/location/expiry meta into the chatbot's system message. A buyer asking "any used road bikes under $500 near Brooklyn" gets a filtered list from live ads, with title, price, location, and posting date. On single ad pages, the current listing's data is already injected, so the bot can answer follow-up questions immediately.

Generic chatbots see the ad post type as opaque content and can't read price, location, or expiry. They invent ads that don't exist, or answer with a generic apology. SleekAI's display conditions let the bot scope to the classifieds archive, single ad pages, or the poster dashboard with separate instructions for each surface.

Classifieds sites live and die by friction. A buyer who has to click through five filters to find one local listing usually bounces. A natural-language chatbot that actually reads the ads can take that same five-filter query and answer it in one sentence.

The problem is that classifieds plugins all store listings as custom post types with category taxonomies and per-listing postmeta, and a generic chatbot sees none of that structure. It can't filter, it can't quote prices, it doesn't know what's expired. SleekAI maps the ad post type, the category taxonomy, and the price/location/expiry meta directly into the system message.

Buyers ask in plain English and get filtered, current answers with seller contact info ready when they're ready to act. Expired ads disappear automatically because the expiry meta is part of the filter. Display conditions let a separate bot run on the poster dashboard with access to plan and expiry info, while the public bot stays scoped to active listings only.

Token usage stays low because most buyer queries are short factual reads. You bring your own OpenAI, Anthropic, Google, or OpenRouter key, so a small classifieds site doesn't pay per-seat for a chatbot. Conversation logs reveal which categories get the most interest and where buyers drop off, surfacing tweaks the site owner usually has to guess at.
