Programmatic SEO for blog posts or standalone pages similar to importing products

Use a custom template and custom dynamic tags to generate content in mass quantities for a CSV.

The CSV would have columns that correspond to the dynamic tags, and each row of the spreadsheet would be a separate blog post/page.

The CSV would populate the dynamic tags used in the template you create to generate the pages.
