Is it necessary to use selling optimized texts in the content?

Question

Search Engine Optimization

I order text from Seopult for sites, but, as I understand it, they are more of a technical nature than practical. Tell me, if I embed it on the page, but hide it in a cascade, is that possible?

Answer 1

You can hide, but there is a high risk of getting a filter.
