A good post from Databox outlining a ton of SEO myths.
The only one I’d quibble with is #40 – about hosting a blog on a subdomain (or even another domain). In the article they state that hosting a blog on a subdomain is a bad idea.
I’d simply counter this by saying that it hasn’t hurt HubSpot’s blog.
btw we covered this in depth in episode 157 of HubShots.
