Explaining SEM, SEA, SEO, SMO…

SEO, SEA, SMO, SEM. You must see these different acronyms regularly on the internet today. If you are a neophyte, their senses are probably unknown to you. If you’re a regular on the web, you probably know a little more, but there may still be some hesitation.

It must be said that many people still mix and disseminate information not always very accurate. We are here today to put an end to this and understand once and for all the relations that these different terms maintain.

What is SEO?

SEO (for Search Engine Optimization – Search Engine Optimization) is nothing but “natural” SEO. That is all the techniques that aim to improve the positioning of a website in a search engine such as Google for example. SEO focuses on three pillars: technique, content and popularity. It is necessary to act on these 3 pillars to improve the visibility of a site on the internet. The technique concerns everything related to the performance of a site (server, technologies used, programming languages ​​used, etc.). The content concerns him the heart of the site: his texts, his images and his videos.

This is the material of the site and what is directly offered to Internet users. Good content is comprehensive, unique and original. Finally the popularity concerns the mentions that make third sites to another Internet site. To illustrate, good content will probably be included on other websites and shared. This is a strong indicator of popularity and therefore quality for a search engine. A site getting a lot of relevant inbound links will be perceived as a quality site.

Mastering SEO is not an easy thing. it requires experience and appropriate training.

What’s SEA ?

SEA (for Search Engine Advertising) defines what is commonly called “paid” SEO. It is really about advertising on a search engine. Google is the best example with its famous Google Ads ad network. You will notice that for some requests, so-called sponsored results (“ads”) appear on the search engine. These are advertising spots purchased. In the case of Google Ads, we buy for example by auction keywords. If our bid is high enough, our ad will appear when a user searches specifically for those keywords.

What’s SMO?

Social Media Optimization (SMO) includes all activities aimed at developing a company’s visibility through social media. The weight of these is not always easy to grasp when focusing on search engines. Indeed, if Youtube and Google+ (the two babies of Google) have a weight, that of other social media such as Facebook, Twitter, LinkedIn, Viadeo and Dailymotion is more relative. Youtube and Google+ are now essential in a search strategy. It is indeed common to see go back Youtube videos in the search results (and Youtube videos go much more than the videos Dailymotion or Vimeo for example) and we must not forget that Youtube is itself the second search engine to the world in terms of volume of research. The same goes for Google+, which, in addition to customizing the SERPs based on the connected user profile, offers many options related to visibility on the results pages: Rich Snippet company, Authorship thumbnail, Local Google+ listing, etc. .

The weight of other social media is more relative (always in the context of the search strategy that we deal with in this article). The profiles come back from time to time, but it is essentially through their power of communication, virality, federation and loyalty that they are very widely distinguished.

What’s SEM then ?

SEM (for Search Engine Marketing – Search Engine Marketing) is a global term taking into account all the techniques to improve the visibility of an entity (site, company, person ..) on the search engines. Therefore, SEM is a collection of marketing techniques and not a marketing technique for say.
