A media kit is a document or presentation that provides information about a website or publication, and that is typically used by advertisers to evaluate the potential value of advertising on that website or publication. A media kit typically includes information about the audience, content, and reach of the website or publication, as well as details about the available ad formats, pricing, and other terms and conditions. A media kit is an important tool for advertisers, as it can provide insights into the potential value and performance of an advertising placement, and can help advertisers to make informed decisions about where to allocate their ad spend. A media kit can also be useful for publishers, as it can help to showcase the value and potential of their website or publication to potential advertisers.
