Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureNina is a done-for-you blog content service for Shopify stores. It researches your brand, writes SEO blog posts in your voice, and adds them to your Shopify blog as drafts for you to review. You review the first batch to set your voice. After that, editors copyedit every post before it reaches you. Nothing publishes automatically; every post arrives as a draft a person approves.
Each run reads the live web first, then writes from what it found and lists the sources in the post, so you can check the facts yourself. It adds an image and fills your SEO title and description on paid plans. Before writing, it checks the title against your blog and skips anything too close, at no charge. Keep every post as a draft until you trust it, then switch to live.
