Weezi you DON'T WANT BIG NUMBERS!!!
The reason we don't want big numbers is that we will be buried in the bottom of a BIG pile. The only way you get to the top of that BIG PILE is if you pay big money to Google Ads.
We want to be at the top of the pile ... YES YES YES... so we needer "smaller piles" and therefore look for useful words that people use but do NOT HAVE SO MUCH COMPTETITION.
Until a person understands SEO there is a misconception to go for the BIG POPULAR WORDS.... it is almost useless.
Make sense yet? If not keep asking questions... I can understand it is difficult to wrap your mind around this concept. It was for me.
