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 hidden text, 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.
And why not? Human beings have always enthralled themselves into one pursuit after another, all with a means to an end of improving our lives. Clearly, the conveniences afforded by the internet are quite literally earth-shattering to say the least. Three decades ago, few could have ever imagined the present state of our on-demand-everything society, with the ability to instantly communicate and conduct business in real-time, at a pace that often seems dizzying at the best of times.
In the parlance of digital marketing, advertisers are commonly referred to as sources, while members of the targeted ads are commonly called receivers. Sources frequently target highly specific, well-defined receivers. For example, after extending the late-night hours of many of its locations, McDonald's needed to get the word out. It targeted shift workers and travelers with digital ads, because the company knew that these people made up a large segment of its late night business. McDonald's encouraged them to download a new Restaurant Finder app, targeting them with ads placed at ATMs and gas stations, as well as on websites that it new its customers frequented at night.
Social media platforms like Yelp and FourSquare are great for brick and mortar businesses looking to implement marketing on social media. Register on these sites to claim your location spot, and then consider extra incentives such as check-in rewards or special discounts. Remember, these visitors will have their phones in hand, so they will be able to write and post reviews. A lot of good reviews can significantly help sway prospective visitors to come in and build your business!
A strategy that is linked into the effectiveness of digital marketing is content marketing.[41] Content marketing can be briefly described as "delivering the content that your audience is seeking in the places that they are searching for it".[41] It is found that content marketing is highly present in digital marketing and becomes highly successful when content marketing is involved. This is due to content marketing making your brand more relevant to the target consumers, as well as more visible to the target consumer.

In 2007, Google announced a campaign against paid links that transfer PageRank.[30] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat any nofollow links, in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[31] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated JavaScript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and JavaScript.[32]

Digital marketing became more sophisticated in the 2000s and the 2010s, when[15][16] the proliferation of devices' capable of accessing digital media led to sudden growth.[17] Statistics produced in 2012 and 2013 showed that digital marketing was still growing.[18][19] With the development of social media in the 2000s, such as LinkedIn, Facebook, YouTube and Twitter, consumers became highly dependent on digital electronics in daily lives. Therefore, they expected a seamless user experience across different channels for searching product's information. The change of customer behavior improved the diversification of marketing technology.[20]
With the explosion of digital media, people began to engage with each other – and the companies they did business with – in new ways. The relevance of traditional print and broadcast channels declined, completely changing the consumer-corporation dynamic. Digital channels opened doors for consumers. No longer passive participants in a one-sided marketing conversation, consumers became empowered authors, publishers and critics. The digital landscape is participatory, an area where consumers exchange ideas. Marketers no longer drive the discussion. Everyday consumers are now the style makers and trendsetters.
When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.
In the social sphere, things change fast. New networks emerge, while others go through significant demographic shifts. Your business will go through periods of change as well. All of this means that your social media strategy should be a living document that you look at regularly and adjust as needed. Refer to it often to keep you on track, but don’t be afraid to make changes so that it better reflects new goals, tools, or plans.
Targeting, viewability, brand safety and invalid traffic: Targeting, viewability, brand safety and invalid traffic all are aspects used by marketers to help advocate digital advertising. Cookies are a form of digital advertising, which are tracking tools within desktop devices; causing difficulty, with shortcomings including deletion by web browsers, the inability to sort between multiple users of a device, inaccurate estimates for unique visitors, overstating reach, understanding frequency, problems with ad servers, which cannot distinguish between when cookies have been deleted and when consumers have not previously been exposed to an ad. Due to the inaccuracies influenced by cookies, demographics in the target market are low and vary (Whiteside, 2016).[44] Another element, which is affected within digital marketing, is ‘viewabilty’ or whether the ad was actually seen by the consumer. Many ads are not seen by a consumer and may never reach the right demographic segment. Brand safety is another issue of whether or not the ad was produced in the context of being unethical or having offensive content. Recognizing fraud when an ad is exposed is another challenge marketers face. This relates to invalid traffic as premium sites are more effective at detecting fraudulent traffic, although non-premium sites are more so the problem (Whiteside, 2016).[44]
An authority website is a site that is trusted by its users, the industry it operates in, other websites and search engines. Traditionally a link from an authority website is very valuable, as it’s seen as a vote of confidence. The more of these you have, and the higher quality content you produce, the more likely your own site will become an authority too.
By utilizing SEM, it provides you with a great avenue for getting the word out quickly and effectively. If you have the budget, then marketing on search engines for competitive keywords might be the right fit for you. But be prepared to pony up. Keywords can range anywhere from a few cents to upwards of $50 and more. The quality score for any term is reflective of what you can expect to pay for bidding on that keyword. The lower the competition, the lower the quality score and the lower the price.

In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[22] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.
With offline marketing, it's very difficult to tell how people are interacting with your brand before they have an interaction with a salesperson or make a purchase. With digital marketing, you can identify trends and patterns in people's behavior before they've reached the final stage in their buyer's journey, meaning you can make more informed decisions about how to attract them to your website right at the top of the marketing funnel.
