Learning Technical SEO

I very well remember the cold sweat on my forehead when I opened our client's analytics reports in May 2012. I was working for an SEO agency in Germany and traffic of a few of our clients had dropped sharply. It was about a week after Google had rolled out "Penguin". Back then, it was perfectly normal to buy some backlinks as part of your SEO strategy. Instead, we start with keyword research, trying to understand user intent, screen the existing content, and… do a technical SEO audit. The latter has become a stable part of every SEO strategy.
