There are many reasons explaining why advertisers choose the SEM strategy. First, creating a SEM account is easy and can build traffic quickly based on the degree of competition. The shopper who uses the search engine to find information tends to trust and focus on the links showed in the results pages. However, a large number of online sellers do not buy search engine optimization to obtain higher ranking lists of search results, but prefer paid links. A growing number of online publishers are allowing search engines such as Google to crawl content on their pages and place relevant ads on it. From an online seller's point of view, this is an extension of the payment settlement and an additional incentive to invest in paid advertising projects. Therefore, it is virtually impossible for advertisers with limited budgets to maintain the highest rankings in the increasingly competitive search market.
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.
Let’s say, for example, that you run a construction business that helps with home repairs after natural disasters and you want to advertise that service. The official term for the service is “fire restoration,” but keyword research may indicate that customers in your area search instead for “fire repair” or “repair fire damage to house.” By not optimizing for these two keywords, you’ll lose out on a lot of traffic and potential customers, even if “fire restoration” is technically more correct.
With the development of this system, the price is growing under the high level of competition. Many advertisers prefer to expand their activities, including increasing search engines and adding more keywords. The more advertisers are willing to pay for clicks, the higher the ranking for advertising, which leads to higher traffic. PPC comes at a cost. The higher position is likely to cost $5 for a given keyword, and $4.50 for a third location. A third advertiser earns 10% less than the top advertiser, while reducing traffic by 50%. The investors must consider their return on investment and then determine whether the increase in traffic is worth the increase.
Facebook pages are far more detailed than Twitter accounts. They allow a product to provide videos, photos, longer descriptions, and testimonials where followers can comment on the product pages for others to see. Facebook can link back to the product's Twitter page, as well as send out event reminders. As of May 2015, 93% of businesses marketers use Facebook to promote their brand. A study from 2011 attributed 84% of "engagement" or clicks and likes that link back to Facebook advertising. By 2014, Facebook had restricted the content published from business and brand pages. Adjustments in Facebook algorithms have reduced the audience for non-paying business pages (that have at least 500,000 "Likes") from 16% in 2012 down to 2% in February 2014. 
On April 24, 2012 many started to see that Google has started to penalize companies that are buying links for the purpose of passing off the rank. The Google Update was called Penguin. Since then, there have been several different Penguin/Panda updates rolled out by Google. SEM has, however, nothing to do with link buying and focuses on organic SEO and PPC management. As of October 20, 2014 Google has released three official revisions of their Penguin Update.
Planned content begins with the creative/marketing team generating their ideas, once they have completed their ideas they send them off for approval. There is two general ways of doing so. The first is where each sector approves the plan one after another, editor, brand, followed by the legal team (Brito, 2013). Sectors may differ depending on the size and philosophy of the business. The second is where each sector is given 24 hours (or such designated time) to sign off or disapprove. If no action is given within the 24-hour period the original plan is implemented. Planned content is often noticeable to customers and is un-original or lacks excitement but is also a safer option to avoid unnecessary backlash from the public. Both routes for planned content are time consuming as in the above; the first way to approval takes 72 hours to be approved. Although the second route can be significantly shorter it also holds more risk particularly in the legal department.
In early 2012, Nike introduced its Make It Count social media campaign. The campaign kickoff began YouTubers Casey Neistat and Max Joseph launching a YouTube video, where they traveled 34,000 miles to visit 16 cities in 13 countries. They promoted the #makeitcount hashtag, which millions of consumers shared via Twitter and Instagram by uploading photos and sending tweets. The #MakeItCount YouTube video went viral and Nike saw an 18% increase in profit in 2012, the year this product was released.
In May 2014, Instagram had over 200 million users. The user engagement rate of Instagram was 15 times higher than of Facebook and 25 times higher than that of Twitter. According to Scott Galloway, the founder of L2 and a professor of marketing at New York University's Stern School of Business, latest studies estimate that 93% of prestige brands have an active presence on Instagram and include it in their marketing mix. When it comes to brands and businesses, Instagram's goal is to help companies to reach their respective audiences through captivating imagery in a rich, visual environment. Moreover, Instagram provides a platform where user and company can communicate publicly and directly, making itself an ideal platform for companies to connect with their current and potential customers.
Search engines reward you when sites link to yours – they assume that your site must be valuable and you’ll rank higher in search results. And the higher the “rank” of the sites that link to you, the more they count in your own ranking. You want links from popular industry authorities, recognized directories, and reputable companies and organizations.
Digital marketing poses special challenges for its purveyors. Digital channels are proliferating rapidly, and digital marketers have to keep up with how these channels work, how they're used by receivers and how to use these channels to effectively market things. In addition, it's becoming more difficult to capture receivers' attention, because receivers are increasingly inundated with competing ads. Digital marketers also find it challenging to analyze the vast troves of data they capture and then exploit this information in new marketing efforts.
