The 3i principles are the foundation tenets of the Digital Marketing Institute framework for successful search marketing. They stand for Initiate, Iterate, Integrate. By keeping these 3is in mind as you progress through this course, when the time comes to develop your own search marketing strategy, you will find it much easier, more accurate, and well-informed. The core value of the DMI 3i methodology is the centrality of the consumer, who we optimize towards and seek out wherever they are. Let’s take a look at what exactly each of these 3is mean.
A search engine is a program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the web. Search engines are an applied form of information retrieval, which is a field of study in computer science.
A search engine results page (SERP) is displayed by a search engine in response to a query from a searcher. Search engines have one major function: they provide answers to user queries through lists of relevant pages that they have retrieved and ranked for relevancy.
Paid advertising makes up the bulk of a search engine results page above the fold, because this is where search engines like Google make most of their revenue. When people click on ads, Google gets paid, and that’s the bulk of their profits. These paid ads are the result of Google Ads advertising.
Organic search results are shown on a SERP below the paid ads. Google feels these are the most relevant and trustworthy results to show for any given query. The order in which they appear represents the relevance and trust Google accords to these results. A high ranking on Google means that a webpage is shown near the top of the organic search results.
Users tend to click more on the organic search results than on the paid ads, as the former are considered more trustworthy and relevant. Usually when users recognize an ad as a paid ad, they’re less likely to click on it, and prefer to click on the organic results below it.
Generally speaking, all search engines have three main processes: the crawler, the indexer, and the query engine.
The process for paid advertising is very different from the one for organic search. Advertisers choose keywords that they want to advertise on. Whenever their keyword is searched for, it triggers a live auction.
Google determines which ad is shown first and second and third, depending on the bids that the advertiser has put in for that particular keyword, as well as the quality score of their ad and their landing page. Those combined result in an ad rank, and the ad with the highest ad rank is shown as the first ad.Back to Top
