Installs other plugins without clearly asking. Basic features are broken.

First, the biggest flaw:
This plugin’s installation wizard installs Google Analytics by MonsterInsights without asking clearly. It does ask if you want to enable analytics during installation but does not clearly and honestly disclose that it will be downloading and installing another plugin and then spamming the back end with a huge error banner until you activate it. I assumed, by design, that the AIOSEO plugin would be providing analytics to me.
Yes, I know there is a tiny, single-line fine print buried down at the very bottom of the page, but this is not enough nor acceptable notice of what is happening. It is dishonest and purposely misleading.

Then, the plugin doesn’t fully work. You cannot add Keyphrases (It seems broken. Nothing happens.)
It also complains that you’r meta-description is too short, but the meta-description field says your meta-description is too many characters long… at the same time.

These things are major issues.
