Search engine marketing is the practice of marketing a business using paid advertisements that appear on search engine results pages (or SERPs). Advertisers bid on keywords that users of services such as Google and Bing might enter when looking for certain products or services, which gives the advertiser the opportunity for their ads to appear alongside results for those search queries.
Internet marketing isn’t like having the confused shopper experience, where you’re holding an organic and non-organic apple in your hand, wondering which one is truly better. A combined strategy of using organic search with paid search is a powerful one-two punch strategy that increases traffic, generates leads, and converts window shoppers into loyal, repeat customers.
Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above. A 2012 Google study found that 81% of ad impressions and 66% of ad clicks happen when there is no associated organic search result on the first page. Research has shown that searchers may have a bias against ads, unless the ads are relevant to the searcher's need or intent 
An organic content marketing system is customer-centric, focusing on giving your customers an improved online experience. You aren’t paying for your place. So, you need valuable content that provides answers to questions, and highlights why you have the best solution. If you establish yourself as a good source of essential content, you build an engagement with customers. And, in turn, you build your brand. But this type of marketing requires time and effort, and a good system is essential to reap rewards.
As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.
It works in a similar way as a canonical tag does to show when a duplicate version of a page exists. But in this case, it helps Google index local content easier within local search engines. It also helps to pass trust across sites and improve the way Google crawls these pages.

Optimize for opt-ins. Make sure you lead to something more than your content. What this means is that when people read your content, they must know where to go next. This may come in the form of a call to action or your offering of additional content, appearing perhaps as a PDF. Growing organic traffic is important, but it doesn’t matter if you are not converting those viewer into leads. Your business doesn’t pay its bills using raw traffic.
Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized, but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.
