With email marketing automation, you can write and design your emails, and schedule them to send at any time you want. In addition to scheduling emails, many email service providers give you the option to set up triggers that start campaigns based on leads’ and customers’ actions or inaction. For example, if a lead opts in for a free piece of content on your site, you can set an email to automatically deliver that content to their inbox. Conversely, if a lead doesn’t take any actions with your business for an extended amount of time, you can set their inaction to trigger a cold lead re-engagement campaign.

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.
