La generación de leads potenciales puede tener sus límites. Por ejemplo, los sorteos y los concursos podrían proporcionar muchas pistas, pero es posible que muchos usuarios sólo hayan participado porque querían ganar un premio atractivo y, por lo demás, no estaban interesados en la empresa, sus productos o sus servicios. Por esta razón, los premios para la generación de leads con sorteos deben ser tan relevantes como sea posible para lo que la empresa ofrece.

Also known as a publisher, the affiliate can be either an individual or a company that markets the seller’s product in an appealing way to potential consumers. In other words, the affiliate promotes the product to persuade consumers that it is valuable or beneficial to them and convince them to purchase the product. If the consumer does end up buying the product, the affiliate receives a portion of the revenue made.
Know the legal requirements. Most visitors will probably understand that advertisements lead to your personal compensation, but if you write a review or use an in-text link as a recommendation, you must explicitly state that each purchase using that link can generate revenue for you. This isn't just good business: it's also required by law. If you don't disclose affiliate or revenue-generating links, you could face legal and financial penalties.
The advertising company sets the terms of an affiliate marketing program. Early on, companies largely paid the cost per click (traffic) or cost per mile (impressions) on banner advertisements.

En respuesta a esta pregunta, podemos decir que para la generación de leads son indispensables las dos, ya que una se complementa con la otra. De nada nos sirve tener una cantidad altísima de datos de usuarios si la mayoría de los mismos no son contactos de calidad, es decir, no son contactos interesados (aunque sea en un futuro) en nuestro productos o servicios, y por tanto, difícilmente terminarán comprándonos (que recordamos es nuestro objetivo final).

"Why aren't millennials moving?" The subject line of this email campaign reads before citing interesting data about relocation trends in the U.S. Trulia doesn't benefit from people who choose not to move, but the company does benefit from having its fingers on the pulse of the industry -- and showing it cares which way the real estate winds are blowing.
Spam is the biggest threat to organic search engines, whose goal is to provide quality search results for keywords or phrases entered by their users. Google's PageRank algorithm update ("BigDaddy") in February 2006—the final stage of Google's major update ("Jagger") that began in mid-summer 2005—specifically targeted spamdexing with great success. This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.[33]
