20 Awesome Sources of Free Data

Everyone loves free things right?

You’ll find plenty of free information of varying quality and accuracy online, but these twenty (+) sources are widely considered to be quite reputable.

If you’re after solid data to help support your digital marketing and content goals, look no further.

1. Google Dataset Search

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

While this could be viewed as a one-stop-shop for datasets that include data from sources like NASA and ProPublica, there are many niche datasets that 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.

With this tool, you can search for keywords and see a variety of information about them, including interest over time, interest by region, related topics, and related queries.

You can select options including which country (or worldwide) you want to see, narrow it down to categories, or confine your search to all of the web, images, news, shopping, or YouTube.

You can also compare your search to another topic.
