Reasons Why Search Engine Marketing Is Getting More Popular In Past Decade

Introduction to SEM or PPC or Paid Advertisements

Search engine marketing (SEM) refers to advertising or marketing a business using paid advertisements that appear on search engine results pages (or SERPs) along with organic (natural or unpaid) search results. Advertisers bid on keywords that customers use on search engines, such as Google, yahoo, Bing, etc to search for certain products or services. This (SEM) gives the advertiser(s) an opportunity to place their ads above or alongside organic (natural or unpaid) results for those search queries.

Traditionally, Search Engine Marketing consisted of the following components:

  1. Search Engine Optimization (SEO): It is the practice of applying techniques to maximize your website’s (or web page’s) ranking in organic or natural search results. Organic search results are the rankings of websites (or web pages) returned by a search engine after you search for a specific “keyword(s)” or “keyword phrase”. Under this, owners of website(s) do not pay Google even a single penny. SEO rankings (the higher the better, obviously) are determined by each search engine’s secret algorithm (a process or set of rules to be followed to calculate rank) that considers factors such as freshness, originality, relevance, number and quality of links (to trustworthy and authoritative websites), and site architecture to determine the position of website for a query.
  2. Paid per click (PPC) advertising: These are the advertisements, advertisers place for their website(s) on search engine(s), such as, Google, Bing, Yahoo, etc. Advertisers bid the amount they are willing to pay per click. More the advertisers bid, greater are the chances of their advertisements appearing higher in search engine results. To ensure quality advertisements (although paid), Google AdWords​ has implemented an additional factor of Quality Score (which includes expected click through rate, ad relevancy and landing page experience) along with maximum cost per click that the advertiser is willing to pay for each click. It is almost impossible to manipulate the Quality Score which is an ingredient of Ad Rank. Higher Ad Rank results in higher position of search engine results page.

With the passage of time, Search Engine Optimization (SEO) has evolved into separate specialized field and Search Engine Marketing has been used interchangeably with paid advertising. Some people also use the following terms to refer to Paid Advertising or Search Engine Marketing:

  • Paid search
  • Paid search advertising
  • Paid search ads
  • PPC (“pay per click” or “pay per call”)
  • CPC (cost per click)
  • CPM (cost per thousand impressions)


Growing Importance of SEM or PPC

An advertiser may or may not decide to use search engine marketing as part of his marketing or advertising strategy. If the advertiser doesn’t have a Website for his business and doesn’t plan to have one in near future, he certainly doesn’t need search engine marketing. However, it is advisable for businesses in today’s scenario to have business website.

Compared to traditional (offline) marketing and advertising, PPC or SEM can be very cost effective. The results of implementing PPC or SEM are almost instantaneous and measurable. It is very easy to make mid-term course corrections in PPC campaigns or SEM (which is quite unlike traditional marketing).

Search Engine Marketing Terms Explained:

Given below is a list of Search Engine Marketing (SEM) terms which are explained. Efforts have been made to include all terms related to SEM.

Actual cost per click (CPC): The actual cost-per-click (actual CPC) is the final amount an advertiser is charged for a click on his advertisement. Advertiser is often charged less, sometimes much less, than the maximum cost-per-click (max. CPC) bid allowed by the advertiser.

Advert (Ad): This is sponsored result(s) that appears on a search engine results page (SERP) when a query is entered in a search engine. Adverts (Ads) are generally a few lines of text and may include additional information like business address, site links to additional pages, location maps, phone numbers, etc.

Ad rank: This is the value that is used to determine an ad’s position in search results. Ad rank is calculated using Max CPC and the Quality Score (includes expected click through rate, ad relevance and landing page experience) and the expected impact of extensions.

Average ad position: The position or placement of advertiser’s ad on the search engine results page (SERP). Search engines typically denote the highest position as ‘Position 1’. If advertiser’s ad appears half the time in Position 3 and half the time in Position 5, advertiser’s average ad position would be 4.

Click through rate (CTR): It is the number of clicks that advertisers ad receives divided by the number of times his ad was shown i.e. number of clicks ÷ impressions = CTR. For example, if you had 10 clicks and 1000 impressions, then your CTR would be 1%.

Conversion rate: The conversion rate is the percentage of visitors to an advertiser’s website that complete a desired goal (sign, purchase, etc) out of the total number of visitors. High conversion rates are indicative of successful marketing. Conversion rates vary from industry to industry.

Cost per click (CPC): Cost Per Click (CPC) refers to the actual price an advertiser pays for each click in his pay per click (PPC) advertising campaign.

Cost per acquisition (CPA): Cost per acquisition (CPA), also known as “Cost per action” or “cost per conversion”, is an online advertising pricing model where the advertiser pays Google for a specified acquisition, for example a sale, click, or form submit (e.g., newsletter sign up, etc.)

Goals/conversions: Using values for goals lets an advertiser focus on the highest value conversions, such as, transactions with a minimum purchase value. When a visitor to an advertiser’s website or user of an advertiser’s application performs an action defined as a goal, Analytics records that as a conversion.

Impressions: It is the measure of the number of times an advertisement was shown – it doesn’t necessarily mean someone clicked on it.
