The search data is meant to support the accusations. A main point is that other methods of supporting such statements (like surveys) are unreliable.
> So nobody googles if their daughter is smart?
The article doesn't say that, it says parents are about twice as likely to google if their son is smart vs daughter.
> Maybe its because parents are worried that looks and not intelligence are important for cohesing in school and not getting bullied, for girls.
This seems like exactly the problem the author wants to bring up and address. Society values appearance above intelligence in women. This is apparently also true in how parents see their children.
The author doesn't draw conclusions about this prejudice, he is merely remarking that it exists.
The author conclude that this mean there is a bias against girls.
Sure, parents who are interested in their children's well-being will also be interested in what society thinks of their children.
This data seems like a weird source for the claim, though; I'll bet the people searching the internet for "is my daughter smart" significantly outnumber the people searching for "is my daughter pretty".
But maybe the real question is, why aren't people asking "Is Reese Witherspoon's daughter smart?"
Millions do. Just 2 times less millions that people who wonders if their sons are smart. Which was explained in depth in the article.
>Maybe its because parents are worried that looks and not intelligence are important for cohesing in school and not getting bullied, for girls. (...)
This sounds more like a "totally unsupported" claim that what the article suggests. And even if that was the case, it would show the same stereotyping done by the parents as the article already suggests.
