Write the listing once. The adapter turns it into versions that fit each channel's fields, lengths and style, with the same facts everywhere.
Titles, bullets, tags, item specifics and SEO fields are filled for each channel from one master record.
If a channel needs a fact your master listing lacks, such as a GTIN or a material, it is listed so you can add it once.
Does it post to my channels?
No. It writes the content for each channel for you to paste in.
Are the limits exact?
It uses general limits, which vary by category and change. Check each channel before publishing.
