  • Initial File Load = includes all assets and files necessary (.html, .js, .ccs. .woff, images, etc. for completing the first visual display of the ad. The initial file load size of an ad is limited in order to preserve the page load performance and thus the user’s web browsing experience. For non-rich media ads, the initial file load size limit is all that’s allowed for the ad. Host Initiated Subload = the additional file limit allowed for rich-media ads that is auto-initiated.
