28 Awesome Sources Of Free Data

Explore this list of reliable and reputable free data sources to power your data-driven narratives and marketing campaigns.

We all love free stuff, don’t we?

The internet is awash in an endless stream of information – mostly free and valuable, yet susceptible to manipulation and misinformation. That’s why, to navigate it effectively, vigilance is crucial.

Data is a critical component of SEO content strategy. Basing your writing on reliable data shows a commitment to accuracy, building your authority and credibility in readers’ eyes. This approach to content and accuracy maps to the signals that search engines use to determine things like E-E-A-T.

Using good data increases the quality of your content and also helps your audience navigate misinformation. Luckily, you absolutely can find data that is both free and trustworthy.

If you’re after solid data, explore this list of reputable, free data sources spanning diverse disciplines – all while avoiding the pitfalls of false information.

1. Google Dataset Search

This enables you to search available datasets that have been marked up properly according to the standard.

While this could be viewed as a one-stop-shop for datasets that include data from sources like NASA and ProPublica, many niche datasets may be better for certain purposes, of course.

You’re shown the results, and each one is clickable to tell you the name of the dataset, when it was last updated, and a description.

With certain results, you get more information, such as the formats in which the dataset is available.
