However, if you're going to understand online marketing, you have to understand the importance of building Google's trust. There are three core components involved here. These three core components are like the pillars of trust that comprise all of Google's 200+ ranking factor rules. Each of those rules can be categorized and cataloged into one of these three pillars of trust. If you want to rank on the first page or in the first spot, you need to focus on all three, and not just one or two out of three.
When traffic is coming to your website or blog, nearly unfettered, it gives you the opportunity to test out a variety of marketing initiatives. However, without that traffic, you're forced to spend money on costly ads before really determining the effectiveness of your offers and uncovering your cost-per acquisition (CPA), two things which are at the core of scaling out any business online.
Gaining Google's trust doesn't happen overnight. It takes time. Think about building up your relationship with anyone. The longer you know that person, the more likely that trust will solidify. So, the reasoning is, that if Google just met you, it's going to have a hard time trusting you. If you want Google to trust you, you have to get other people that Google already trusts, to vouch for you. This is also known as link-building.

The Economist reported a recent conference in Rome on the subject of the simulation of adaptive human behavior.[61] It shared mechanisms to increase impulse buying and get people "to buy more by playing on the herd instinct." The basic idea is that people will buy more of products that are seen to be popular, and several feedback mechanisms to get product popularity information to consumers are mentioned, including smart-cart technology and the use of Radio Frequency Identification Tag technology. A "swarm-moves" model was introduced by a Florida Institute of Technology researcher, which is appealing to supermarkets because it can "increase sales without the need to give people discounts."

Conversion rate optimization is still possibly one of the most underutilized but critical functions of digital marketing. Every element of digital marketing is useless without considering conversion rates. This goes for SEO, SEM, Social Media, Email, and Display. The power of your SEO rankings are only as good as your click through rates and your traffic is only valuable of your website and landing pages foster some type of “action.” Why spend all the time and energy driving traffic through multiple different channels if you are not willing to spend the time and energy on conversion optimization? Yet many brands and agencies still put less emphasis on this crucial piece of the puzzle.
Use personalization. Personalizing the content of your emails (depending on your segment from Chapter 3) will make it so much more relevant and valuable to them. Personalization goes beyond sticking your subscriber’s first name into the email. You need to tailor the actual content of the email to address their needs. For instance, an online retailer will find it much more valuable to read an email with the subject line, “How to build backlinks to your eCommerce store” than just a generic subject line, “How to build backlinks.”

The use of this data is becoming less “creepy” and using it in a deliberate way can deliver success. If you haven’t done so already, you should make it a priority to collect and use more data for personalization in content execution. Marketers should implement/expand their current preference centers for content choices or follow browse, purchase, click and open behavior to identify the content that piques subscribers’ interest most.
