Does it cut off the SEO if they are used HTML block for products description ?
Does it matter if the description will be in a standard way or HTML BLOCK ?
Using an HTML block for product descriptions doesn’t cut off SEO. It can still be SEO-friendly if the content is properly optimized. it depends on the content of the HTML Block. Adding an HTML block with some SEO content has the same effect if you add this content directly to product description without HTML block.
