BrandMentions offers historical data from the very beginning. If you want to extract historical data there’s a button on your the top right part of your dashboard that says Extract Historical Data:
Once you click on the button we’ll extract the historical mentions that we find on web and social for the past year for your current project. The extraction process may take up to an hour.
We are able to provide data for more than a year. If you are interested in this, please contact us.
