In continuation of Google saying they have a stupid high limit on the number of links it can extract from a page, Google is also saying there is no optimal number of links you should have on a page. Google's John Mueller was asked about it and he responded on Twitter saying "there is no optimal number of links on a page."
Here are those tweets where John said this:
There is no optimal number of links on a page.

True, I don't think Google has a specific number of links they want to see on a page.
