How does hashes and parameters in the URL affect SEO?

Question

Search Engine Optimization

Good afternoon. Social network ratings are published on our website: https://br-analytics.ru/mediatrends/authors/
There was an idea, in order to raise the search ranking, somehow unify the URL.
1. Go to a link when selecting a select with an indication of a social network, for example: "/mediatrends/authors/facebook"
+ own meta tags 2. When switching a select, add or change
url parameters, for example "/mediatrends/authors?facebook"
tags script
Here plus - no reload
3. Similar to item 2 but with hashes
Question: What implementation will affect the rating in search engines? In general, parameters or hashes affect the search?
Thank you.

Answer 1

Good afternoon, the
hash is the anchor on the page, so the content of this hash must always be present at the given url. Based on your description, the content on the page will change depending on the parameter after the hash. And this is not acceptable for search engines. Accordingly, this option is not suitable. Otherwise, your PS rating will be downgraded
PS - the hash can be indexed by search engines. But the preferred option for PS is ajax (!#), get parameter or url without parameters.
Using get parameters or url without parameters will not affect your ranking in any way, just like ajax. The main thing is not to duplicate content on the site.

Answer 2

In your case, only the source will be relevant.
And, in both cases, you can do it without rebooting. Forcibly change the get parameters on the CNC URL, and the address will be as in the first option
