Most "About' pages tell the reader something about the person or company who makes the website.
I have written many 'About', pages. I don't like any of them. When I read them later, I either feel like I was bragging or they don't say anything.
When I go to the 'About' page on websites, I'm trying to figure out if the creator of the site is qualified to provide the content in the site.
Let me put your mind to rest. I'm not an expert on this stuff. Especially not an expert on Google's website builder. I'm just using my 45 years of experience on technology to see how it works.
