Search engine marketing (SEM) is a form
of Internet marketing that involves the promotion of websites by increasing
their visibility in search engine results pages (SERPs) primarily through paid
advertising.[1] SEM may incorporate search engine optimization (SEO), which
adjusts or rewrites website content and site architecture to achieve a higher
ranking in search engine results pages to enhance pay per click (PPC)
listings.[2]

Market
In 2007, U.S. advertisers spent US $24.6
billion on search engine marketing.[3] In Q2 2015, Google (73.7%) and the
Yahoo/Bing (26.3%) partnership accounted for almost 100% of U.S. search engine
spend.[4] As of 2006, SEM was growing much faster than traditional advertising
and even other channels of online marketing.[5] Managing search campaigns is
either done directly with the SEM vendor or through an SEM tool provider. It may
also be self-serve or through an advertising agency. As of October 2016, Google
leads the global search engine market with a market share of 89.3%. Bing comes
second with a market share of 4.36%, Yahoo comes third with a market share of
3.3%, and Chinese search engine Baidu is fourth globally with a share of about
0.68%.[6]
History
As the number of sites on the Web
increased in the mid-to-late 1990s, search engines started appearing to help
people find information quickly. Search engines developed business models to
finance their services, such as pay per click programs offered by Open Text[7]
in 1996 and then Goto.com[8] in 1998. Goto.com later changed its name[9] to
Overture in 2001, was purchased by Yahoo! in 2003, and now offers paid search
opportunities for advertisers through Yahoo! Search Marketing. Google also
began to offer advertisements on search results pages in 2000 through the
Google AdWords program. By 2007, pay-per-click programs proved to be primary
moneymakers[10] for search engines. In a market dominated by Google, in 2009
Yahoo! and Microsoft announced the intention to forge an alliance. The Yahoo!
& Microsoft Search Alliance eventually received approval from regulators in
the US and Europe in February 2010.[11]
Search engine optimization consultants
expanded their offerings to help businesses learn about and use the advertising
opportunities offered by search engines, and new agencies focusing primarily
upon marketing and advertising through search engines emerged. The term
"search engine marketing" was popularized by Danny Sullivan in
2001[12] to cover the spectrum of activities involved in performing SEO,
managing paid listings at the search engines, submitting sites to directories,
and developing online marketing strategies for businesses, organizations, and
individuals.
Methods and metrics
Search engine marketing uses at least
five methods and metrics to optimize websites.[citation needed]
Keyword research and analysis involve
three "steps": ensuring the site can be indexed in the search
engines, finding the most relevant and popular keywords for the site and its
products, and using those keywords on the site in a way that will generate and
convert traffic. A follow-on effect of keyword analysis and research is the
search perception impact.[13] Search perception impact describes the identified
impact of a brand's search results on consumer perception, including title and
meta tags, site indexing, and keyword focus. As online searching is often the
first step for potential consumers/customers, the search perception impact
shapes the brand impression for each individual.
Website saturation and popularity, or how
much presence a website has on search engines, can be analyzed through the
number of pages of the site that are indexed by search engines (saturation) and
how many backlinks the site has (popularity). It requires pages to contain
keywords people are looking for and ensure that they rank high enough in search
engine rankings. Most search engines include some form of link popularity in
their ranking algorithms. The following are major tools measuring various aspects
of saturation and link popularity: Link Popularity, Top 10 Google Analysis, and
Marketleap's Link Popularity and Search Engine Saturation.
Back end tools, including Web analytic
tools and HTML validators, provide data on a website and its visitors and allow
the success of a website to be measured. They range from simple traffic
counters to tools that work with log files and to more sophisticated tools that
are based on page tagging (putting JavaScript or an image on a page to track
actions). These tools can deliver conversion-related information. There are
three major tools used by EBSCO: (a) log file analyzing tool: WebTrends by
NetiQ; (b) tag-based analytic tool: WebSideStory's Hitbox; and (c)
transaction-based tool: TeaLeaf RealiTea. Validators check the invisible parts
of websites, highlighting potential problems and many usability issues and
ensuring websites meet W3C code standards. Try to use more than one HTML
validator or spider simulator because each one tests, highlights, and reports
on slightly different aspects of your website.
Whois tools reveal the owners of various
websites and can provide valuable information relating to copyright and
trademark issues.
Google Mobile-Friendly Website Checker:

design.[14]
Search engine marketing is a way to
create and edit a website so that search engines rank it higher than other
pages. It should be also focused on keyword marketing or pay-per-click
advertising (PPC). The technology enables advertisers to bid on specific
keywords or phrases and ensures ads appear with the results of search engines.
With the development of this system, the
price is growing under a 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.[15] 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%.[15]
Investors must consider their return on
investment when engaging in PPC campaigns. Buying traffic via PPC will deliver
a positive ROI when the total cost-per-click for a single conversion remains
below the profit margin. That way the amount of money spent to generate revenue
is below the actual revenue generated.
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.[16] 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.
Google's search engine marketing is one
of the western world's marketing leaders, while its search engine marketing is
its biggest source of profit.[17] Google's search engine providers are clearly
ahead of the Yahoo and Bing network. The display of unknown search results is
free, while advertisers are willing to pay for each click of the ad in the
sponsored search results.
Paid inclusion
Paid inclusion involves a search engine
company charging fees for the inclusion of a website in their results pages.
Also known as sponsored listings, paid inclusion products are provided by most
search engine companies either in the main results area or as a separately identified
advertising area.
The fee structure is both a filter
against superfluous submissions and a revenue generator. Typically, the fee
covers an annual subscription for one webpage, which will automatically be
catalogued on a regular basis. However, some companies are experimenting with
non-subscription based fee structures where purchased listings are displayed
permanently. A per-click fee may also apply. Each search engine is different.
Some sites allow only paid inclusion, although these have had little success.
More frequently, many search engines, like Yahoo!,[18] mix paid inclusion
(per-page and per-click fee) with results from web crawling. Others, like
Google (and as of 2006, Ask.com[19][20]), do not let webmasters pay to be in
their search engine listing (advertisements are shown separately and labeled as
such).
Some detractors of paid inclusion allege
that it causes searches to return results based more on the economic standing
of the interests of a web site, and less on the relevancy of that site to
end-users.
Often the line between pay per click
advertising and paid inclusion is debatable. Some have lobbied for any paid
listings to be labeled as an advertisement, while defenders insist they are not
actually ads since the webmasters do not control the content of the listing,
its ranking, or even whether it is shown to any users. Another advantage of
paid inclusion is that it allows site owners to specify particular schedules
for crawling pages. In the general case, one has no control as to when their
page will be crawled or added to a search engine index. Paid inclusion proves
to be particularly useful for cases where pages are dynamically generated and
frequently modified.
Paid inclusion is a search engine
marketing method in itself, but also a tool of search engine optimization since
experts and firms can test out different approaches to improving ranking and
see the results often within a couple of days, instead of waiting weeks or
months. Knowledge gained this way can be used to optimize other web pages, without
paying the search engine company.
Comparison with SEO
SEM is the wider discipline that
incorporates SEO. SEM includes both paid search results (using tools like
Google Adwords or Bing Ads, formerly known as Microsoft adCenter) and organic
search results (SEO). SEM uses paid advertising with AdWords or Bing Ads, pay
per click (particularly beneficial for local providers as it enables potential
consumers to contact a company directly with one click), article submissions,
advertising and making sure SEO has been done. A keyword analysis is performed
for both SEO and SEM, but not necessarily at the same time. SEM and SEO both
need to be monitored and updated frequently to reflect evolving best practices.
In some contexts, the term SEM is used
exclusively to mean pay per click advertising,[2] particularly in the
commercial advertising and marketing communities which have a vested interest
in this narrow definition. Such usage excludes the wider search marketing
community that is engaged in other forms of SEM such as search engine
optimization and search retargeting.
Creating the link between SEO and PPC
represents an integral part of the SEM concept. Sometimes, especially when
separate teams work on SEO and PPC and the efforts are not synced, positive
results of aligning their strategies can be lost. The aim of both SEO and PPC
is maximizing the visibility in search and thus, their actions to achieve it
should be centrally coordinated. Both teams can benefit from setting shared
goals and combined metrics, evaluating data together to determine future
strategy or discuss which of the tools works better to get the traffic for
selected keywords in the national and local search results. Thanks to this, the
search visibility can be increased along with optimizing both conversions and
costs.[21]
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.
Ethical questions
Paid search advertising has not been
without controversy and the issue of how search engines present advertising on
their search result pages has been the target of a series of studies and
reports[23][24][25] by Consumer Reports WebWatch. The Federal Trade Commission
(FTC) also issued a letter[26] in 2002 about the importance of disclosure of
paid advertising on search engines, in response to a complaint from Commercial
Alert, a consumer advocacy group with ties to Ralph Nader.
Another ethical controversy associated
with search marketing has been the issue of trademark infringement. The debate
as to whether third parties should have the right to bid on their competitors'
brand names has been underway for years. In 2009 Google changed their policy,
which formerly prohibited these tactics, allowing 3rd parties to bid on branded
terms as long as their landing page in fact provides information on the
trademarked term.[27] Though the policy has been changed this continues to be a
source of heated debate.[28]
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 had released three
official revisions of their Penguin Update.
In 2013, the Tenth Circuit Court of
Appeals held in Lens.com, Inc. v. 1-800 Contacts, Inc. that online contact lens
seller Lens.com did not commit trademark infringement when it purchased search
advertisements using competitor 1-800 Contacts' federally registered 1800
CONTACTS trademark as a keyword. In August 2016, the Federal Trade Commission
filed an administrative complaint against 1-800 Contacts alleging, among other
things, that its trademark enforcement practices in the search engine marketing
space have unreasonably restrained competition in violation of the FTC Act.
1-800 Contacts has denied all wrongdoing and appeared before an FTC administrative
law judge in April 2017.[29]
Examples
AdWords is recognized as a web-based
advertising utensil since it adopts keywords that can deliver adverts
explicitly to web users looking for information in respect to a certain product
or service. It is flexible and provides customizable options like Ad
Extensions, access to non-search sites, leveraging the display network to help
increase brand awareness. The project hinges on cost per click (CPC) pricing
where the maximum cost per day for the campaign can be chosen, thus the payment
of the service only applies if the advert has been clicked. SEM companies have
embarked on AdWords projects as a way to publicize their SEM and SEO services.
One of the most successful approaches to the strategy of this project was to
focus on making sure that PPC advertising funds were prudently invested.
Moreover, SEM companies have described AdWords as a practical tool for
increasing a consumer’s investment earnings on Internet advertising. The use of
conversion tracking and Google Analytics tools was deemed to be practical for
presenting to clients the performance of their canvas from click to conversion.
AdWords project has enabled SEM companies to train their clients on the utensil
and delivers better performance to the canvass. The assistance of AdWord
canvass could contribute to the growth of web traffic for a number of its
consumer’s websites, by as much as 250% in only nine months.[30]
Another way search engine marketing is
managed is by contextual advertising. Here marketers place ads on other sites
or portals that carry information relevant to their products so that the ads
jump into the circle of vision of browsers who are seeking information from
those sites. A successful SEM plan is the approach to capture the relationships
amongst information searchers, businesses, and search engines. Search engines
were not important to some industries in the past, but over the past years the
use of search engines for accessing information has become vital to increase
business opportunities.[31] The use of SEM strategic tools for businesses such
as tourism can attract potential consumers to view their products, but it could
also pose various challenges.[32] These challenges could be the competition
that companies face amongst their industry and other sources of information
that could draw the attention of online consumers.[31] To assist the combat of
challenges, the main objective for businesses applying SEM is to improve and
maintain their ranking as high as possible on SERPs so that they can gain
visibility. Therefore, search engines are adjusting and developing algorithms
and the shifting criteria by which web pages are ranked sequentially to combat
against search engine misuse and spamming, and to supply the most relevant
information to searchers.[31] This could enhance the relationship amongst
information searchers, businesses, and search engines by understanding the
strategies of marketing to attract business.
