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.[26] 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.[27] Patents related to search engines can provide information to better understand search engines.[28] In 2005, Google began personalizing search results for each user. Depending on their history of previous searches, Google crafted results for logged in users.[29]

Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches.[64] In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007.[65] As of 2006, Google had an 85–90% market share in Germany.[66] While there were hundreds of SEO firms in the US at that time, there were only about five in Germany.[66] As of June 2008, the market share of Google in the UK was close to 90% according to Hitwise.[67] That market share is achieved in a number of countries.
Instagram has proven itself a powerful platform for marketers to reach their customers and prospects through sharing pictures and brief messages. According to a study by Simply Measured, 71% of the world's largest brands are now using Instagram as a marketing channel.[58] For companies, Instagram can be used as a tool to connect and communicate with current and potential customers. The company can present a more personal picture of their brand, and by doing so the company conveys a better and true picture of itself. The idea of Instagram pictures lies on on-the-go, a sense that the event is happening right now, and that adds another layer to the personal and accurate picture of the company. In fact, Thomas Rankin, co-founder and CEO of the program Dash Hudson, stated that when he approves a blogger's Instagram post before it is posted on the behalf of a brand his company represents, his only negative feedback is if it looks too posed. "It's not an editorial photo," he explained, "We're not trying to be a magazine. We're trying to create a moment."[57] Another option Instagram provides the opportunity for companies to reflect a true picture of the brandfrom the perspective of the customers, for instance, using the user-generated contents thought the hashtags encouragement.[59] Other than the filters and hashtags functions, the Instagram's 15-second videos and the recently added ability to send private messages between users have opened new opportunities for brands to connect with customers in a new extent, further promoting effective marketing on Instagram.
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]

Social media marketing, or SMM, is a form of internet marketing that involves creating and sharing content on social media networks in order to achieve your marketing and branding goals. Social media marketing includes activities like posting text and image updates, videos, and and other content that drives audience engagement, as well as paid social media advertising.


Twitter allows companies to promote their products in short messages known as tweets limited to 140 characters which appear on followers' Home timelines.[33] Tweets can contain text, Hashtag, photo, video, Animated GIF, Emoji, or links to the product's website and other social media profiles, etc.[34] Twitter is also used by companies to provide customer service.[35] Some companies make support available 24/7 and answer promptly, thus improving brand loyalty and appreciation.
For example, what are the quality and quantity of the links that have been created over time? Are they natural and organic links stemming from relevant and high quality content, or are they spammy links, unnatural links or coming from bad link neighborhoods? Are all the links coming from the same few websites over time or is there a healthy amount of global IP diversification in the links?
Social media often feeds into the discovery of new content such as news stories, and “discovery” is a search activity. Social media can also help build links that in turn support into SEO efforts. Many people also perform searches at social media sites to find social media content. Social connections may also impact the relevancy of some search results, either within a social media network or at a ‘mainstream’ search engine.
However, with all of these so-called modern conveniences to life, where technology's ever-pervading presence has improved even the most basic tasks for us such as hailing a ride or ordering food or conducting any sort of commerce instantly and efficiently, many are left in the dark. While all of us have become self-professed experts at consuming content and utilizing a variety of tools freely available to search and seek out information, we're effectively drowning in a sea of digital overload.
Several customers are turning towards social media to express their appreciation or frustration with brands, product or services. Therefore, marketers can measure the frequency of which customers are discussing their brand and judge how effective their SMM strategies are. In recent studies, 72% of people surveyed expressed that they expected a response to their complaints on Twitter within an hour.[111]
The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. The Yahoo! Directory and DMOZ, two major directories which closed in 2014 and 2017 respectively, both required manual submission and human editorial review.[40] Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links[41] in addition to their URL submission console.[42] Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click;[43] however, this practice was discontinued in 2009.

A content marketer, for example, can create a series of blog posts that serve to generate leads from a new ebook the business recently created. The company's social media marketer might then help promote these blog posts through paid and organic posts on the business's social media accounts. Perhaps the email marketer creates an email campaign to send those who download the ebook more information on the company. We'll talk more about these specific digital marketers in a minute.
