Today’s internet searchers are savvy: they know there’s a lot of BS out there.
So first and foremost, data is an important part of executing trustworthy content. As one of my direct response mentors used to say “it’s hype unless you can prove it.”
But, data is also a powerful asset in content marketing for another reason that many don’t immediately think of—it can also help you create more interesting (read: linkable) content too.
For example, data can be the basis for a unique story or angle that people find intriguing, like this analysis of the most charming cities which uses publicly available third-party data (like how many antique stores there are) to determine which mid-sized cities in America are great to visit.
Or, it can be the basis for a piece that helps your readers draw new insights on a topic that’s critical to their business, like this piece from GetVoIP on the worst interview processes, which has 33 unique domains linking to it, including Business Insider and Fast Company.
Data can even be a content asset all by itself, like this customer service stats post from Nextiva which has 300+ different domains linking to it.
Simply put, if you want to create content that both people and search engines like, data is an important part of it. So here are 106 trustworthy, free data sources that will help you build linkable content both search engines and people love.
