Black hat SEO refers to the practice of trying to trick the search engines into giving you higher rankings by using unethical tactics, such as buying links. The risk is just too great. Even if you enjoy a temporary boost in rankings due to black hat tactics, it’s likely to be short lived. Google is getting better and better at spotting dirty tricks and sooner or later the progress you made will be wiped out by an algorithm update, or worse, your site will get removed from the index altogether.

PPC (paid search marketing): PPC (pay per click) advertising involves paying to have search engines display your website offer in or alongside search results. For example, Google's Adwords program will display your ad at the top or right side of the search results page (placement depends on many factors including keywords and quality of ad). Google will also feed your ads to websites running its Adsense program. There are other types of PPC marketing, such as Facebook Ads. In PPC advertising, you pay each time someone clicks on your offer. Paid search differs from organize search in that you're paying to have your website or offer displayed higher in search results.

There is limited real estate for the top positions in organic search results. With the amount of content on the web today and the number of competitors you have, it can be hard to get in a top position, even despite your best efforts. If you’re a new business or an existing one trying to build your online presence, SEM/PPC advertising can get you in front of highly targeted customers.
By 2004, search engines had incorporated a wide range of undisclosed factors in their ranking algorithms to reduce the impact of link manipulation. In June 2007, The New York Times' Saul Hansell stated Google ranks sites using more than 200 different signals.[25] The leading search engines, Google, Bing, and Yahoo, do not disclose the algorithms they use to rank pages. Some SEO practitioners have studied different approaches to search engine optimization, and have shared their personal opinions.[26] Patents related to search engines can provide information to better understand search engines.[27] In 2005, Google began personalizing search results for each user. Depending on their history of previous searches, Google crafted results for logged in users.[28]
The stats tell the truth: the top ad spot gets about 2% of clicks (CTR) on average, whereas the top organic spot gets about 20 times that, 40%. Why? Because people trust it more. They trust the Google brand to deliver the most relevant results to their search query. Anyone paying for an ad might be perceived as just trying to hijack that process for a quick buck. It generally takes 3 months to earn the top organic spot with Google (there are exceptions to this), whereas it takes around 3 minutes to place an ad to get the top spot. Society values those who have earned their way to the top in any field, rather than bought their way.
Webmasters and content providers began optimizing websites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all webmasters needed only to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed.[5] The process involves a search engine spider downloading a page and storing it on the search engine's own server. A second program, known as an indexer, extracts information about the page, such as the words it contains, where they are located, and any weight for specific words, as well as all links the page contains. All of this information is then placed into a scheduler for crawling at a later date.
I still believe that Facebook and Google are great platforms to promote your business, but only if you are willing to pay. If your goal is Organic growth, I recommend looking at newer platforms such as Quora, Reddit, Snapchat, Medium, Instagram, Tumblr and similar. These are all established platforms that still offer some opportunities for organic reach, because although popular, they are nowhere near the saturation levels of Facebook and Google. You can also look at startups that you feel will become very successful in the future, take a small gamble perhaps and try to establish a strong presence there.
Let’s assume that your goal is customer acquisition. You know you’ve acquired a customer when you make a sale. So, you’d set up a sales conversion goal. To do that, click on “New Goal.” In the goal setup section, you can either select “template” or “custom.” Custom gives you more flexibility, so go with that option. Go on to the “goal description.” This is where you define your goal by naming it and selecting the type. For customer acquisition, you want to select “Destination.”
SEO may generate an adequate return on investment. However, search engines are not paid for organic search traffic, their algorithms change, and there are no guarantees of continued referrals. Due to this lack of guarantees and certainty, a business that relies heavily on search engine traffic can suffer major losses if the search engines stop sending visitors.[60] Search engines can change their algorithms, impacting a website's placement, possibly resulting in a serious loss of traffic. According to Google's CEO, Eric Schmidt, in 2010, Google made over 500 algorithm changes – almost 1.5 per day.[61] It is considered wise business practice for website operators to liberate themselves from dependence on search engine traffic.[62] In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.
However, with a properly created PPC campaign, results can be analyzed and any conversion-related problems can fixed within no time. It shouldn’t be surprising to see massive results from a PPC campaign that’s been running only for a few weeks. When and if you have the budget, getting quick results with PPC is not only possible, it’s completely doable.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
