Plug in SEO ‑ SEO Audit & Fix

Most Shopify stores leave SEO to chance. Plug In SEO scans every page, finds what's broken, and lets you fix image alt text, file names, URLs and meta tags in bulk — not one product at a time. AEO tools help AI search engines find you. AI keyword research finds what shoppers are searching for. AI then writes your titles and descriptions using those keywords — you approve every change. Get cited in AI search, not just ranked on Google.

Qikify Custom Product Options

Let AI scan your store and suggest option sets, or start from a template, then edit them. Add product options without creating extra variants: text boxes, image and color swatches, dropdowns, date pickers and file uploads. Use conditional logic to show options based on earlier choices or Shopify variants, and add price add-ons for engraving, gift wrap or rush orders. Options show on orders, emails and invoices, and you can ask Shopify Sidekick about your setup in Shopify admin.
