1. Develop leads. Leads eventually turn into sales, ideally. How that conversion occurs varies widely among industries and business models. A lead might consist of a registered site visitor, a newsletter subscriber, or simply a visitor who bookmarks the site for future visits.
2. Sell your products. Major e-commerce sites use the AdWords program to propel direct sales.
3. Sell someone else’s product. This is the realm of affiliate marketing, which is prominent in AdWords. Affiliate ads are always marked with the word affiliate (or the abbreviation aff) in the ad copy.
4. Increase impressions. For sites that earn advertising revenue, the value of traffic lies in generating the largest number of ad displays.
5. Capture coordinates. Capturing the visitor’s e-mail address (and perhaps mailing address) allows the business to develop a more direct relationship with that person, leading to direct communication, repeat visits, or eventual sales.
6. Build a brand. Brand recognition is enhanced differently in AdWords than in traditional media advertising. AdWords ads do not build brand recognition by means of graphics, like a banner, TV, or magazine ad. However, some advertisers see value in driving traffic to a Web site that does use graphics to increase recognition. Brand-building may also occur when people see AdWords ads for something that they don’t associate with a business, such as Wal-Mart ads appearing for the keyword jewelry.
