Many times these two have often been confused to mean the same thing, and there has been much debate about which one of the two carries much weight. In one scenario, search engine optimization SEO is downplayed, and in other situations, search engine marketing is downplayed. Technically, the two cannot be used interchangeably, because they are two separate entities, even though it seems like they are cut from the same cloth. Anyway, let’s do a comparative analysis for both, to determine their differences and more so to scale their importance.

What is Search Engine Optimisation SEO?

There are many definitions for SEO online. However, a simple definition for SEO is optimizing websites for search engine visibility i.e. Google and Bing. In reality, it is not that simple, SEO can be a very rigorous task. That being said, a technical definition of SEO is, the process of applying a set of principles on your web pages and web contents in order to make search engine algorithms understand what your website or web page is all about. For example, when a search query is made on Google for the keyword “What is SEO”? Google uses web crawlers to find publicly available web pages that are relevant to the keyword or keyword phrase, after the pages are crawled, only the web pages that the web crawlers deem very relevant are returned and displayed in the search result pages of Google. However, SEO isn’t just about making web crawlers understand web pages. It’s is also about making people understand web pages too. As a matter of fact, the latter has equal importance or even more important than the former.

There are four stages in the SEO process: The Optimising Stage, the Crawling Stage, the Indexing Stage, and the ranking Stage.

The Optimising stage.

There are certain key elements on every web page that should be optimised when doing (on-page SEO), these key elements are the title, meta description, meta tags, URL structure, body tags, keyword density, image alt-text and finally internal links, schema markup, web page speed, https, sitemaps and other ranking factors. These factors affect a web page’s ranking on search engines. Thus, it is recommended that best practice should be followed when optimizing these elements.

The Crawling Stage

Billions of web pages are being crawled by search engines daily using web crawlers (also known as bots, robots or spiders) to find and retrieve web pages to index. The web crawlers follow links on web pages, gathers information about these web pages and sends the information back to Google index server. In other for web pages to be found in Google, they must be visible to the web crawlers, if the web pages are not visible to web crawlers, these web pages won’t be sent to the Google index because the web crawlers couldn’t access them. Hence, why it is important to optimize the key elements mentioned in the optimizing stage.

The Indexing Stage

The information retrieved from web pages by web crawlers are sent to Google index where they undergo a ranking process. Not all web pages are indexed by Google, for example, some web pages are coded not to be indexed by Google. That being said, the web pages that are returned and displayed in the search engine result pages SERPS, are index pages of websites found by the web crawlers. Typically, the index web pages contain the page’s URL, title and meta description.

The Ranking Stage

The Google index takes the information (content) it receives from the web crawlers and uses it to rank web pages according to their relevance, authority, and importance. In other words, the web pages that are displayed on the first pages of the search result are believed to be imperative and highly relevant to the search query.

In lieu of the above, we can evidently say that SEO (On page and off page) plays a very important role in the way web pages are ranked by Google.

Now that we have an idea on the importance of SEO, let us look at the search engine marketing SEM and how it differentiates from SEO.

What is Search Engine Marketing SEM?

search_engine_marketing_Mississauga_SEMIn a layman’s term, Search engine marketing SEM is simply paying search engines i.e. Google and Bing to show your web pages ideally on the first pages of search engine results when a search query is made for the keyword or keyword phrase in which you paid (bided) for. Think of SEM as a form of advertising web pages on search engines solely to increase visibility or boost traffic. It is like a shortcut to ranking a website on first pages of search engines i.e. Google.

Pay Per Click (PPC), Cost Per Click (CPC), Cost Per Impression (CPM), Paid Search Advertising (PSA) are terms usually associated with SEM.

How does search engine marketing work?

Google AdWords and Yahoo Bing are major online advertising platforms most advertisers use to promote websites online. Apparently, this is one of the greatest strength of SEM over SEO, as it offers advertisers the opportunity to advertise websites on the first pages of search engine results pages SERPs. In other words, web pages or websites that aren’t ranking on the first pages of i.e. Google, due to lack of search engine optimization (SEO), apparently can pay (bid) for their web pages or websites to be on first pages of Google.

That sounds like an easy way out eh? It is not as easy as it seems, it is quite competitive in the sense that, advertisers bid for the same keywords and hope their ads are displayed on the first pages of the search results.

There are four stages in the SEM process: The ad campaign creation the bidding, and ad copy optimization stage, the auction stage and the ad ranking stage

The Ad Campaign Creation, The Bidding and Ad Copy Optimisation Stage

Advertisers create a campaign in i.e. Google AdWords, choose a bidding strategy and optimize the ad campaign (ad copy). Ideally, the ads are optimized to target a web page (landing page). The Landing pages experience impacts on the Quality score of the ad campaign.

The Auction Stage

Search engines auctions a position repeatedly for every search made. For example, when someone searches for dog training in Google, AdWords system finds all ads that have bided for the keyword “dog training” and enters them into an auction.

The Ad Ranking Stage

Amongst the ad copy (keywords) that are entered into the auction, only those with the highest ‘Ad rank” are displayed in an order e.g from 1 to 500. The order in which the ads are shown depends on a combination of factors i.e. bid, ad quality score, language preferences, their location, the time of day, the expected impact of extensions and other ad formats that influence how Google shows ads on search engine result pages for a particular keyword or keyword phrase.

Certainly, search engine marketing (SEM) is an easy, effective and amazingly powerful way to build traffic to websites and grow a business. However, In order for it to be effective, it requires a good bidding strategy, ad copy should be optimized, landing pages should be optimized (SEO) and relevant to the ad-copy.

Closing Thoughts

Evidently, we can say one of the greatest strength of search engine marketing (SEM) is that it is easy and faster way to be on the first pages of Google search result pages as opposed to search engine optimization (SEO) which requires time, lots of efforts and most importantly patience.

Both SEO and SEM have their unique strengths and are equally important for ranking web pages and websites. Although proponents of SEO would say organic search as it relates to SEO carries more weight than SEM, similarly proponent of SEM would say paid search as it relates to SEM carries more weight than SEO. I choose to be indifferent. That is why we offer both services. SEO and SEO
