Word of mouth communications and peer-to-peer dialogue often have a greater effect on customers, since they are not sent directly from the company and are therefore not planned. Customers are more likely to trust other customers’ experiences.[24] Examples can be that social media users share food products and meal experiences highlighting certain brands and franchises. This was noted in a study on Instagram, where researchers observed that adolescent Instagram users' posted images of food-related experiences within their social networks, providing free advertising for the products.[28]
Another part of SEM is social media marketing (SMM). SMM is a type of marketing that involves exploiting social media to influence consumers that one company’s products and/or services are valuable.[22] Some of the latest theoretical advances include search engine marketing management (SEMM). SEMM relates to activities including SEO but focuses on return on investment (ROI) management instead of relevant traffic building (as is the case of mainstream SEO). SEMM also integrates organic SEO, trying to achieve top ranking without using paid means to achieve it, and pay per click SEO. For example, some of the attention is placed on the web page layout design and how content and information is displayed to the website visitor. SEO & SEM are two pillars of one marketing job and they both run side by side to produce much better results than focusing on only one pillar.
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]
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.[61] 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.[62] It is considered a wise business practice for website operators to liberate themselves from dependence on search engine traffic.[63] In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.
Google's core algorithms and its propensity to shroud its data in layers of obscurity is not something new. However, it is critical to any understanding of marketing on the internet simply because this visibility is at the heart of everything else that you do. Forget about social media and other forms of marketing for the time being. Search engine optimization (SEO) offers up the proverbial key to near-limitless amounts of traffic on the web.
SEO is not an appropriate strategy for every website, and other Internet marketing strategies can be more effective, such as paid advertising through pay per click (PPC) campaigns, depending on the site operator's goals. Search engine marketing (SEM) is the practice of designing, running and optimizing search engine ad campaigns.[56] Its difference from SEO is most simply depicted as the difference between paid and unpaid priority ranking in search results. Its purpose regards prominence more so than relevance; website developers should regard SEM with the utmost importance with consideration to visibility as most navigate to the primary listings of their search.[57] A successful Internet marketing campaign may also depend upon building high quality web pages to engage and persuade, setting up analytics programs to enable site owners to measure results, and improving a site's conversion rate.[58] In November 2015, Google released a full 160 page version of its Search Quality Rating Guidelines to the public,[59] which revealed a shift in their focus towards "usefulness" and mobile search. In recent years the mobile market has exploded, overtaking the use of desktops, as shown in by StatCounter in October 2016 where they analyzed 2.5 million websites and found that 51.3% of the pages were loaded by a mobile device [60]. Google has been one of the companies that are utilizing the popularity of mobile usage by encouraging websites to use their Google Search Console, the Mobile-Friendly Test, which allows companies to measure up their website to the search engine results and how user-friendly it is.
Prioritizing clicks refers to display click ads, although advantageous by being ‘simple, fast and inexpensive’ rates for display ads in 2016 is only 0.10 percent in the United States. This means one in a thousand click ads are relevant therefore having little effect. This displays that marketing companies should not just use click ads to evaluate the effectiveness of display advertisements (Whiteside, 2016).[44]
SEO often involves improving the quality of the content, ensuring that it is rich in relevant keywords and organizing it by using subheads, bullet points, and bold and italic characters. SEO also ensures that the site’s HTML is optimized such that a search engine can determine what is on the page and display it as a search result in relevant searches. These standards involve the use of metadata, including the title tag and meta description. Cross linking within the website is also important.
SEO (search engine optimization) for organic search: SEO is a free method of SEM that uses a variety of techniques to help search engines understand what your website and web pages are about so they can deliver them to web searchers. These techniques include things like using titles, keywords, and descriptions in a website and webpage's meta tags, providing relevant content on the topic, using various heading tags (i.e. 

), and linking to and from quality online resources. 

Two other practical limitations can be seen in the case of digital marketing. One,digital marketing is useful for specific categories of products,meaning only consumer goods can be propagated through digital channels.Industrial goods and pharmaceutical products can not be marketed through digital channels. Secondly, digital marketing disseminates only the information to the prospects most of whom do not have the purchasing authority/power. And hence the reflection of digital marketing into real sales volume is skeptical.[citation needed]
Page and Brin founded Google in 1998.[23] Google attracted a loyal following among the growing number of Internet users, who liked its simple design.[24] Off-page factors (such as PageRank and hyperlink analysis) were considered as well as on-page factors (such as keyword frequency, meta tags, headings, links and site structure) to enable Google to avoid the kind of manipulation seen in search engines that only considered on-page factors for their rankings. Although PageRank was more difficult to game, webmasters had already developed link building tools and schemes to influence the Inktomi search engine, and these methods proved similarly applicable to gaming PageRank. Many sites focused on exchanging, buying, and selling links, often on a massive scale. Some of these schemes, or link farms, involved the creation of thousands of sites for the sole purpose of link spamming.[25]

Content is king. It always has been and it always will be. Creating insightful, engaging and unique content should be at the heart of any online marketing strategy. Too often, people simply don't obey this rule. The problem? This takes an extraordinary amount of work. However, anyone that tells you that content isn't important, is not being fully transparent with you. You cannot excel in marketing anything on the internet without having quality content.

Collaborative Environment: A collaborative environment can be set up between the organization, the technology service provider, and the digital agencies to optimize effort, resource sharing, reusability and communications.[38] Additionally, organizations are inviting their customers to help them better understand how to service them. This source of data is called User Generated Content. Much of this is acquired via company websites where the organization invites people to share ideas that are then evaluated by other users of the site. The most popular ideas are evaluated and implemented in some form. Using this method of acquiring data and developing new products can foster the organizations relationship with their customer as well as spawn ideas that would otherwise be overlooked. UGC is low-cost advertising as it is directly from the consumers and can save advertising costs for the organisation.
The marketing automation coordinator helps choose and manage the software that allows the whole marketing team to understand their customers' behavior and measure the growth of their business. Because many of the marketing operations described above might be executed separately from one another, it's important for there to be someone who can group these digital activities into individual campaigns and track each campaign's performance.
