Question: I need a platform that offers historical Twitter data for tracking audience sentiment and campaign success.

If you want a service to monitor audience sentiment and gauge campaign success on Twitter, Trendsmap is a great option. It includes more-advanced analytics and visualization tools, like historical charts and topic tracking by country or region. With a decade or more of historical data, you can filter results by country, language and time period, and it's a good tool for professionals like journalists, researchers, investigators and marketers.

Another strong contender is Talkwalker, a consumer intelligence platform that offers social listening, media monitoring and social benchmarking tools. Talkwalker tracks 30 social networks and 150 million websites around the world, and its AI-powered tools can analyze sentiment and spot influencers. The service is geared for businesses that want to build better marketing programs and engage customers better by making data-driven decisions.

If you want a more general-purpose data collection service, check out Datashake, which can gather and analyze data in many formats, including social media. Datashake uses machine learning to process raw data, and it offers programming interfaces so you can integrate it with other tools. It can be used for tracking campaigns and monitoring brands, so it's a good option for companies trying to get their data operations in order.
