Let's say my website is centered about "widgets".
The domain name itself is a popular phrase that companies widely use in my country as the title for their job offerings page so it's something like:
www.widgetwithus.ex
The website lists companies and have corresponding page titles like:
Widget Company Name
Some time ago, Google started changing titles adding the domain name, which is quite normal so in the serps they became:
Widget Company Name - Widgetwithus.ex
Lately for some reason Google decided to add "Widget with us" after the domain name and the result is:
Widget Company Name - Widgetwithus.ex - Widget with us
Which not only looks bad but it's also redundant.
A couple of considerations:
1. Pages rank fairly well for both "widget company name" and "company name widget with us" even if "widget with us" is not present on the pages, not even in the page headings or content.
2. Since Google started to give less importance to domain names, rankings for "company name widget with us" degraded slighlty but noticeably and other sites that include "widget with us" in the page titles have taken over.
My questions:
1. Any idea about why Google is adding both the sitename AND "widget with us" to every page?
2. Do you think it might me a good idea to spontaneously change page titles to "Widget Company name" or "Company name widget with us"
3. If changing titles is a good idea, is it a good idea to change them on 400 pages alltogether?
Thanks
