Runner divided Runet into audience sources

... It should be understood that the Runner advertisers now have the opportunity to conduct advertising campaigns only on blog users who undoubtedly represent a special layer of the audience. Or to build complex behavioral communications with millions of visitors to email web-based services or dating services (for example, Mamba has recently been running a Runner ad). The Navigation catalogs that are in a separate source also deserve attention. That is, about a small number of sites, which are popularly called doorways, you can now forget without simply activating this source.
