Frequently Asked Questions

Does dirty HTML affect my Shopify store speed?

+

Yes. Inline styles and empty wrapper elements from Google Docs add unnecessary bytes to every page. For product pages that load thousands of times daily, this bloat compounds into real performance and SEO impact.

Can I clean Shopify product descriptions?

+

Yes. Copy your existing product description HTML, paste it into Publish Helper, clean it, and paste it back. This is a quick way to reduce page weight across your entire catalog.

Does this work with Shopify's Blog editor?

+

Absolutely. Shopify's blog editor has an HTML view (the '<>' button) where you can paste clean HTML from Publish Helper for perfectly formatted blog posts.
