Pukulink lets you search for products, insert product cards, keep prices up to date, and track link clicks from within WordPress.

Works with both the Classic Editor and the Block Editor.
Search Amazon, Rakuten Ichiba, and Yahoo! Shopping, then insert a product card.
Save favorite Rakuten Ichiba and Yahoo! Shopping stores and search within a specific store.
Link products that you have confirmed are the same item across stores, then show each store’s price and retrieval date on one card.
Refine the search keyword used by stores that do not have a linked product. The card title remains unchanged.
Includes automatic price updates, per-card price visibility, sale labels, review links, and click tracking.
When Amazon Creators API eligibility is temporarily unavailable, Amazon search links can still be inserted.
Includes six templates: Standard, Compact, Large Card, Modern, Text Link, and Comparison Buttons.
Optionally show extra Amazon or Rakuten Ichiba product photos as a gallery on the Standard, Large Card, and Modern templates, with swipe, arrow buttons, and keyboard support. Each card can override the site setting to always show or always hide its gallery.
AI markers let you replace [pukulink_draft keyword="product name"] placeholders with product cards after reviewing search results. Each product is selected and confirmed by the user.
Optionally outputs schema.org Product/Offer JSON-LD.
Rakuten Ichiba and Yahoo! Shopping links can also use Moshimo Affiliate by importing IDs from Easy Link code.
The Product Health report lists products that may no longer be available.
Export settings, the product registry, history, and click totals as JSON.

In accordance with the Yahoo! Shopping API guidelines, Pukulink automatically displays the required Web Services by Yahoo! JAPAN attribution at the bottom of pages that show Yahoo! product information.

Posts store the portable [pukulink] shortcode. Affiliate URLs are assembled when a page is displayed, so changing a setting updates existing cards without editing each post.
