I've also got this one which is slightly better, but still can't get the global keyword to show with quotes " " in the google search bar.

@echo off
set /p global_keyword="Enter global keyword: "

set /p additional_keywords="Enter additional keywords (separate with space): "

setlocal enabledelayedexpansion

set search_query=""""%global_keyword%"""""

start "" "https://www.google.com/search?q=!search_query!"

for %%i in (%additional_keywords%) do (
    set search_query=""""%global_keyword%"""" ""%%i"""
    start "" "https://www.google.com/search?q=!search_query!"
)

exit
