100 Free Data Sources for Content and Digital PR Campaigns

Written by Rebecca Moss

There are a number of reasons why we place such a big emphasis on data when it comes to content marketing and digital PR campaigns. We’ve even explored how journalists use data as a way to craft compelling stories, and how digital PR teams can look to implement these techniques into their campaigns.

Data has the power to:

  • Measure your online standing – Website traffic, social media followers and online ratings.
  • Analyse the effectiveness of your work – Open rates, click-through rates, bounce rates and cost per conversion.
  • Discover your return on investment – Calculate your cost per lead or quantity of leads generated.

However, it can also be a game-changer in terms of content creation – there’s a wealth of data available online just waiting to be curated, which can provide your audience with intriguing insights or indisputable information that encourages movement down the funnel towards those all-important conversions.
