The unique advantage of PPC marketing is that Google (and other ad networks) don’t just reward the highest bidders for that ad space, they reward the highest-quality ads (meaning the ads that are most popular with users). Essentially, Google rewards good performance. The better your ads, the greater your click-through rates and the lower your costs.
Reason: When a visitor sticks around on your site for a minute or less, you can consider their stay to be negligible. When a visit exceeds that amount of time, the visitor has more potential for becoming a client and an increased chance of converting on your calls-to-action. If a visitor spends a considerable amount of time on your website, they are likely to come back or to take action on conversion areas you have included in your site (call-to-actions, downloads, contact forms, etc.).
The effectiveness of geo-targeting is only going to further improve as mobile use grows and location data becomes more accurate and available.
