Welcome to your guide on data sources in Explore. Explore analyzes billions of results on a live basis and new content is collected 24 hours a day, seven days a week. This article contains information about Meltwater sources and also demographics, such as the countries and languages. Read below to learn more:


Twitter is an online social networking service and microblogging service that enables its users to send and read text-based posts of up to 280 characters, known as Tweets. Meltwater has access to the full Twitter firehose, enabling users 15 months of historic Twitter content.


A blog is a personal journal published on the web consisting of discrete entries or "posts", typically displayed in reverse chronological order. It is usually themed on a single subject and written by an individual or small group. Most blogs allow readers to post comments or interact with each other via the blog, unlike a static website. Over 1.5 million blogs are posted per day from over 29 million unique social blogs. We define social blogs as all blogs, except for editorial blogs. Editorial blogs are blogs associated with news sites such as http://www.mercurynews.com/blogs. Meltwater crawls these blogs the same way we crawl news documents, but we make them available as a separate source type in editorial searches.


A forum, sometimes called a message board, is an online discussion site where people can hold conversations in the form of posted messages. A forum can have many separate discussions going on at a time and each one is referred to as a thread. Usually, a forum has an underlying theme or topic like politics, sports, technology, fashion, etc. By pulling in around 5.2 million forum posts per day, you will have access to more targeted content in regards to your topic of interest.


Reddit is a social sharing website. It is home to social news aggregation, web content ratings, and discussions. Registered members submit content to the site such as links, text posts, and images, which are then voted up or down by other members. Approximately 6 million Reddit posts are pulled into Explore daily.

Product Reviews

Product review sites are web pages where users can rate products. They may be dedicated product comparison sites or the review sections of large e-commerce companies like amazon.com.

By monitoring Product Reviews, you can gauge customer satisfaction and gain deeper insights into your products and competitors by tapping into over 865,000 reviews pulled in daily.


News is copyrighted content from news sources such as The New York Times, BBC, CNN, local newspapers, and online journals. Content posted on television networks' websites is also classified as News. Over 3 million traditional media articles a day are crawled through Meltwater's news sources.


On many websites (news and blogs primarily) users can leave comments at the bottom of the page. By monitoring these comments, you will be able to gain a deeper context-specific understanding of your brand by instantly sifting through approximately 2.2-million comments pulled into our system each day.
