About Structured Data and Rich Snippets

Good evening everyone
I want to ask a 100-point expert question

Rich snippets that increase the user’s click-through rate in Google search queries
(Excluding Breadcrumbs)

and

Is there anyone who fully understands the labeling system called Structured Data that we add so Google bots crawl our site more reasonably?

1- Site search box
(Despite applying all templates, it never appeared)
2- Site Organization structure
(Search for google.com on Google and look at the right side)

These two are the ones I am most troubled by; Google never displayed these 2 structures on my site.
I tried JSON-LD template, and the Schema org structure as well.

Aside from this, is there anyone who has organized their entire site with schema and seen benefits?

I mean someone who has well analyzed the differences between the version without schema and after adding schema, and benefited from it

When all conditions are equal—which is really hard to ensure—but
at least for 2 domains opened on the same day with absolutely no history

which of these 4 methods seems more reasonable to you

Standard Html coding
Html coding + Schema
Html 5 coding
Html 5 + Schema

E.g.
[HTML]

  • #
  • [/HTML]

    instead of

    [HTML]

    [/HTML]

    When we used this, I personally witnessed the links appearing regularly under the site getting messed up. But I don’t know the reason.

    I thank in advance the friends who will answer these humble questions.

    You can try the Schema structure I devised below.

    [HTML]

    ##

    #

    #
    # #
    #
    1. #

      #

    [/HTML]

    I am also seriously curious about this topic; I look forward to the opinions of friends with knowledge and experience.

    It interested me, but I don’t have enough knowledge to put forward an idea. Following.

    This topic is a sore spot for me, believe me, it’s nothing else.

    You go and learn all the libraries and how to use them, but then you can’t test whether it’s useful or useless :slight_smile:
    Frankly, it’s a funny situation

    Just a small detail I can share

    Structured data and Rich snippets are two labeling methods designed with the exact same logic; the difference is this:

    Rich snippets make you appear different in search results.
    Structured data, on the other hand, helps Google bots read the marked data more accurately.

    That’s it.

    With the template I shared above, I reached 72k traffic from 0 between October 2nd and April 15th, but I couldn’t tell if the cause was Structured data or my project itself.

    I’ve removed the structured data for 15 days to test it.

    I added the JSON template inside the Google search box and organization, I’m waiting, I’ll let you know
