Companies that invest in Internet marketing generally fall into two camps: those frustrated because their investment isn’t paying off, and those frustrated because they can’t tell.

Companies address the frustration in a number of ways—changing agencies, changing strategies, tweaking this and tweaking that. However, the vast majority of organizations failing or floundering with Internet marketing make one, two, or all three of the worst mistakes possible and never address them. All the agencies, strategies, and tweaks in the world won’t compensate for errors in these three areas. Fix them, and you are on your way to success in SEO, PPC, email marketing, social media, or whatever other online campaigns you’ve got underway.
