Definition of SEM: Search Engine Marketing

What is SEM? (Search Engine Marketing)

SEM, an acronym for Search Engine Marketing, refers to all marketing strategies aimed at improving the visibility of a website on search engines. SEM generally brings together two main levers: SEO (natural referencing) and SEA (paid referencing).

The goal of SEM is to optimize a business's presence in search engine results pages, called SERPs, in order to attract qualified traffic and increase conversions.

In practice, a Search Engine Marketing strategy combines content and site structure optimizations (SEO) with targeted advertising campaigns (SEA) to maximize visibility on strategic keywords.

SEM in digital marketing

In a digital marketing strategy, SEM is an important acquisition lever because it allows you to capture Internet users who already express a search intention.

When a user carries out a search on Google or another engine, they express a need or a specific question. SEM consists of positioning a website on these queries in order to attract visitors interested in the proposed offer.

• attract qualified traffic to a website;
• increase the visibility of a brand in search engines;
• generate leads or sales;
• strengthen the notoriety of a business online.

Search Engine Marketing is often part of an overall acquisition strategy which also includes content marketing, social networks or even email marketing.

How Search Engine Marketing Works

The operation of SEM is based on the analysis of the keywords searched by Internet users and on the creation of content or advertisements adapted to these searches.

Businesses generally start with a keyword study to identify the most relevant queries for their business. These keywords then serve as a basis for:

The two levers of SEM: SEO and SEA

SEM is mainly based on two types of referencing: natural referencing and paid referencing.

SEO (Search Engine Optimization)

SEO corresponds to the optimization of a website to appear in the natural results of search engines. This approach is based in particular on the quality of the content, the structure of the site, the internal networking and the acquisition of external links.

SEO takes time to produce results but it allows you to generate lasting and regular traffic.

SEA (Search Engine Advertising)

SEA corresponds to the distribution of paid advertisements in search engines. Companies generally pay for each click on their ads, which allows you to quickly gain visibility on targeted keywords.

SEA is often used to quickly launch a marketing campaign or to strengthen the presence of a site on competitive queries.

Comparison between SEO, SEA and SEM

Although these three concepts are related, they correspond to different approaches to search engine optimization.

• SEO: natural referencing based on site and content optimization;
• SEA: paid referencing based on the distribution of sponsored ads;
• SEM: global strategy that combines SEO and SEA to maximize visibility.

SEM can therefore be considered as a comprehensive approach to search engine marketing.
