I'm not sure the simple SEO steps described here will really add "millions" to your valuation just like that, but this article really was more interesting than the somewhat link-baity title might suggest.
This is more a why post than a how post. The five minute intervention will not, by itself, add millions, just like your first commit to a version control system won't. However, it is a necessary prerequisite to doing clearly, incontestably valuable things.
I found a funded startup today whose title tag was $COMPANY_NAME. They're in a space where SEO is a clear win and it is obvious no person has spent so much as thirty seconds thinking about it. That's as bad as source control through "I zip up a copy of the code and email it to you."
