A solo ad can be a way of web marketing where an advertiser pays a publisher to deliver a message advertisement on the publisher's opt-in list. The e-mail is shipped towards the list without any other content or advertisements, hence the term "solo."
The aim of a solo ad is to promote a certain product, service, or offer to some targeted audience. The publisher typically lists subscribers that have opted in for emails over a particular topic or niche. The advertiser pays the publisher fees to transmit a solo ad email to the list, which will carries a call-to-action to click on a link towards the advertiser's website or landing page.
Solo ads are generally used in the web marketing industry in order to quickly build a contact list, generate leads, and promote products. However, the effectiveness of solo ads can differ widely with respect to the quality of the email list, the targeting, along with the offer being promoted.
