Mega beckoning in the header of the site for all products, is it practical?

Question

Search Engine Optimization

Good afternoon! A dispute arose with colleagues about the benefits for SEO of using a mega menu for all products, they say, page indexing will be faster since these links will lead to other pages from the main one, the question is, is this true?

Answer 1

In my opinion, indexing will really be faster, but this works when there are around 20 products)))) because if you throw out several hundred links in the menu, this will confuse the user, and no one has canceled the long-forgotten Page rank, where it is not recommended to indicate more than 50 links on the same page.
Therefore, stores use special blocks (popular, new, etc.) for indexing goods
