One of the earliest adopters of Internet marketing in the world of Fortune 500 companies was the Coca-Cola Corporation. Today, this huge purveyor of soft drinks has one of the strongest online portfolios in the world. More than 12,000 websites link to the Coca-Cola homepage, which itself is a stunning display of Internet savvy. Their homepage alone sports an auto-updating social network column, an embedded video, a unique piece of advertising art, frequently rotating copy, an opt-in user registration tab, tie-in branding with pop culture properties, and even a link to the company's career opportunities page. Despite how busy that sounds, the Coca-Cola homepage is clean and easy to read. It is a triumph of Internet marketing for its confidence, personality, and professionalism.

Considering that most marketing involves some form of published media, it is almost (though not entirely) redundant to call 'content marketing' anything other than simply 'marketing'. There are, of course, other forms of marketing (in-person marketing, telephone-based marketing, word of mouth marketing, etc.) where the label is more useful for identifying the type of marketing. However, even these are usually merely presenting content that they are marketing as information in a way that is different from traditional print, radio, TV, film, email, or web media.
The criteria and metrics can be classified according to its type and time span. Regarding the type, we can either evaluate these campaigns "Quantitatively" or "Qualitatively". Quantitative metrics may include "Sales Volume" and "Revenue Increase/Decrease". While qualitative metrics may include the enhanced "Brand awareness, image and health" as well as the "relationship with the customers".
Social media marketing on its own is free to use, as is content marketing if you’re creating and managing the content yourself. Several email marketing platforms have free plans for your first few hundred or thousand subscribers, giving you time to get your revenue increasing before you have to start paying. There are even free keyword research tools like Google’s Keyword Planner that can help you optimize your site at no cost. 

Basically Google uses a complex mathematical formula called an algorithm to give a score to every website and every search people to do in Google to figure out which website should rank best for what people are looking for. Think of the algorithm like a collection of empty buckets. One bucket gives you a score for the quality of your site, one bucket gives you a score for how many sites link to you, one bucket gives you a score for how people trust you. Your job is to fill up more buckets in the algorithm than any other website. You can affect your search engine ranking by having the highest score in terms of quality of your site, of having the highest score in terms of authority of your website, of having the highest score in terms of the most trusted store for that search that people are looking for. The good thing is that there are hundreds of buckets, and for every single one of these buckets these scores put together in the algorithm to figure out where you rank is an opportunity for you to fill it up and rank better. So optimizing your site for search results really means getting the highest score in as many of these points as you can.

That doesn't mean you won't make any money at the outset. No, as long as you configure the right free offer to capture those all-important email addresses on your squeeze pages, and you build a great value chain with excellent sales funnels, you'll succeed. If all that sounds confusing to you, don't worry, you'll learn over time. That's what internet marketing is all about. It's a constant and never-ending education into an oftentimes-convoluted field filled with less-than-scrupulous individuals.

CPC (Cost Per Click) or PPC (Pay per click) means advertisers pay each time a user clicks on the ad. CPC advertising works well when advertisers want visitors to their sites, but it's a less accurate measurement for advertisers looking to build brand awareness.[63] CPC's market share has grown each year since its introduction, eclipsing CPM to dominate two-thirds of all online advertising compensation methods.[24]:18[62]:1
