Display traffic is traffic to your site from ads or banners on other sites. For example, you might pay for placement of a banner on a related site, or run an affiliate program where the ads link back to your site. Display traffic contrasts with organic traffic, which comes from search engines, and paid traffic, which comes from programs like AdWords. If you want to attract display traffic, consider hiring a graphic design expert to create attractive, click-worthy banners.
Whenever advertisers look for direct display ads or sponsored post ads on any blog or website they usually look for the metrics as those are the only signs via which one can get idea about the quality of website before even contacting with the owner. Getting targeted visitors via traffic generation tool will improve the rank and the rank will help you to get more advertisers who will pay you.
