Does changing “search appearance” affect all search engines or only google

HI,

If I change the “search appearance” for my site via the yoast tab in wordpress dashboard OR by editing the page itself by changing the google preview – seo title and meta description, does that affect how the search appearance will look in every search browser (ie; edge, bing, yahoo etc) or does it only effect the google results?

I’m also not getting proper search results in google. Here’s what I did: In “search apparance” under the yoast tab in wp dashboard, for “posts” I used the insert variable function to put in “Title” “Seperator” “Site Title” and for meta description “excerpt” (they all looked like the purple pills), and the “separator” was set to “|”. When I do a search in google everything seems to be correct, except for the “separator” it shows a “-“. Now, trying to change things around, no matter what I do, none of the changes I make are showing up in a google search… it always shows “title” “separator” “site title” with an incorrect “separator”.

In “search appearance” under the yoast tab in wp dashboard, for “Pages” I used the insert variable function to put in “Title” “Seperator” “Tagline” and for meta data “excerpt”.
After entering in that info, I EDITED one of my pages… for that page, in the google preview, for the SEO title I typed in (actually typed it, didn’t use the insert variable function) the following “my domain name” “|” “my tagline”. For the meta description I also typed one in myself.
Problem is, when I do a google search, the page that edited does not show the seo title or meta description I typed in, instead it shows the “Title” “Seperator” “Tagline” with a meta description “excerpt” like I entered in “search appearance”… However, it is showing an OLD tagline and excerpt I had on my page from months ago and is nowhere to be found on my site currently.

Not sure what is going on. Any help is appreciated. Thanks.
