What we learned this week
Every week we pick the most interesting or most educational articles we've found online and share them with our readers in our Link Roundup. Let's get started!
HubSpot wrote up a great post about the history of online advertising. It's a bit of a long read, but it has a lot of good information if you want to understand where we've come from and where we're going.
The guys at Stone Temple argue that focusing on the two most important aspects of SEO (content and links) can be an effective way to get your site to rank.
Another long read - this one from Cognitive SEO - on the relationship between social signals and SEO ranking.
From The SEO Project, this is a pretty definitive list of all the popular link building strategies used by SEOs today.
That's it for this week. Let us know if you found anything especially interesting this week! Leave a comment, or drop us a line on Twitter.
