For example, a site that provides content on building a web site may include an ad for some software. The reason for a higher response is due to a more descriptive advertisement and a high degree of targeting. The only disadvantage is that these lists don't have the same raw numbers of people who can view that ad. If you can find a good one, highly consider this option. Spam is sending emails advertising your site, product, or service.
Companies sell lists of thousands of addresses that they've collected through various means.
It is not the same as opt-in email, because these addresses often are gotten without the consent of the person. Also, the use of spam is forbidden by many service providers, because of the requests from email users to stop such unwanted messages. You may still consider this a reasonable method of advertising but consider the message you are trying to convey about your professionalism. Awards - Submit your site to win an award. This not only provides credibility that your site has been recognized as noteworthy but you often receive a free link from the award site.
