SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[49] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[50]
The Budget: The average lifetime value of a customer is $450. You know that the average purchase is $35. The business makes 20% profit on all sales. Most returning customers buy once a month. Your current monthly sales are $16,000 with a slight increase when seasons change. A steady increase in sales over six months to a 15% increase by month six would mean a total sales increase of $8,400 over the six months and a total lifetime value of around $30,900. Spending $3,000 on the six-month organic marketing campaign would see a return on investment of 106%. The advantage of organic marketing is that it keeps working even after the campaign has ended. This means that the ROI would actually be higher.
Since there is an obvious barrier of entry for anyone trying to beat you once you’re established, you won’t have to worry about having competitors “buying” their way to the top. Their only option is pay per click ads, but then again, it isn’t the same as getting a higher position on the SERPs. Again, this is assuming that you took the right steps and were patient enough to solidify your place in the top search results. 
Make your content longer. Despite video marketing's rise seeming to point to consumers' desire for shorter content, that implication couldn’t be further from the truth. Google wants content that’s longer and more detailed. Studies have shown that this is what ranks higher in the search engines. Don’t artificially inflate your word count, though. You should hone in on topics that naturally require more words to write about.

Improved Ads and Visual Products. PPC Ads are simply Advertisements. With this, they have full control on what they would like their clients to see first-hand. Contact Number, Location, Services, and Pricing are some of the details that they can easily display to clients. Apart from that, images are now readily available so that clients will be able to get a preview of what they are browsing or buying (for selling sites).

Organic search should not be viewed as just one of many different marketing strategies. Instead, it should be the cornerstone of your efforts. Your materials should all be optimized to maximize their appearance on the SERPs. You should also be using the insights that can be gleaned from organic search to inform the rest of your marketing endeavors.

Click through rates: Searches using terms that denote high purchase intent such as product or brand-specific keywords will get more clicks than organic results. The advantage of paid search can clearly be seen in the Internet retailers MarketLive Performance Index data. For the year 2013 as a whole, PPC accounted for 36.5% of search traffic but an outsized 47.9% of revenue from search.
The term “organic” refers to something having the characteristics of an organism. Although black hat SEO methods may boost a website’s search engine page rank in the short term, these methods could also get the site banned from the search engines altogether. However, it is more likely that readers will recognize the low quality of sites employing black hat SEO at the expense of the reader experience, which will reduce the site’s traffic and page rank over time.
In February 2011, Google announced the Panda update, which penalizes websites containing content duplicated from other websites and sources. Historically websites have copied content from one another and benefited in search engine rankings by engaging in this practice. However Google implemented a new system which punishes sites whose content is not unique.[35] The 2012 Google Penguin attempted to penalize websites that used manipulative techniques to improve their rankings on the search engine.[36] Although Google Penguin has been presented as an algorithm aimed at fighting web spam, it really focuses on spammy links[37] by gauging the quality of the sites the links are coming from. The 2013 Google Hummingbird update featured an algorithm change designed to improve Google's natural language processing and semantic understanding of web pages. Hummingbird's language processing system falls under the newly recognised term of 'Conversational Search' where the system pays more attention to each word in the query in order to better match the pages to the meaning of the query rather than a few words [38]. With regards to the changes made to search engine optimization, for content publishers and writers, Hummingbird is intended to resolve issues by getting rid of irrelevant content and spam, allowing Google to produce high-quality content and rely on them to be 'trusted' authors.
In December 2009, Google announced it would be using the web search history of all its users in order to populate search results.[32] On June 8, 2010 a new web indexing system called Google Caffeine was announced. Designed to allow users to find news results, forum posts and other content much sooner after publishing than before, Google caffeine was a change to the way Google updated its index in order to make things show up quicker on Google than before. According to Carrie Grimes, the software engineer who announced Caffeine for Google, "Caffeine provides 50 percent fresher results for web searches than our last index..."[33] Google Instant, real-time-search, was introduced in late 2010 in an attempt to make search results more timely and relevant. Historically site administrators have spent months or even years optimizing a website to increase search rankings. With the growth in popularity of social media sites and blogs the leading engines made changes to their algorithms to allow fresh content to rank quickly within the search results.[34]

Because so few ordinary users (38% according to Pew Research Center) realized that many of the highest placed "results" on search engine results pages (SERPs) were ads, the search engine optimization industry began to distinguish between ads and natural results.[citation needed] The perspective among general users was that all results were, in fact, "results." So the qualifier "organic" was invented to distinguish non-ad search results from ads.[citation needed]
