SMM and SMO - what's the difference?

Before talking about the profession itself and its representatives, let's first deal with this: what is SMM? how is it different from SMO? what role do these components play in promoting the site/product/company on the Internet?

If compared with SEO, then SMO is work directly "on" and "with" the site (internal optimization), and SMM is activity outside of it (external optimization) or marketing in in social networks.

The essence of SMM activity

It is aimed at promoting goods and services posted on the site, in social networks, on forums and blogs in order to make them recognizable and thereby attract targeted visitors - consumers, customers, etc.

SMM is often confused with SMO. However, these two are absolutely different directions works designed to achieve one goal - brand promotion. Unlike SMO, marketing in social networks does not involve any work directly with the company's website, its content, transformation and optimization. All work is carried out on the external site and consists in communicating with a potential audience, attracting new subscribers and future customers to the site, as well as smoothing out conflicts that arise around the company/brand/product through competent responses to negative reviews/comments.

His duty is to achieve specific goals set for the commercial platform (groups, pages, blogs) by communicating with the target audience in the virtual space. At the same time, the tasks can be different: sales, increasing brand awareness and remembering the product, improving the company's image, etc.

Thus, there are two main areas of work of a social media manager:

  • attracting and increasing the audience (subscribers);
  • work with the involved audience (communication, answering questions / comments / working with negative reviews).

What does an SMM manager do during the day?

Given the above, it is interesting to know how the working day of an SMM specialist goes? In order for its work to be effective, it is important to properly organize it. So, during the day, the SMM manager needs:

What is he, an SMM specialist? Qualities required of a professional

Agree, the above tasks cannot be called easy and, of course, not everyone who calls himself an "SMM manager" will be able to do them. What professional and personal qualities should a candidate for this "proud title" possess?

Besides, good specialist must also be technically savvy, own social media tools. So, it will not be superfluous to understand analytics and SEO, programming, understand (at least on basic level) social media API.

5. The most common disease affecting the human skeleton is osteoporosis. This disease is characterized by a decrease in bone mass and increased fragility bones. According to the WHO, in Europe, mortality from fractures associated with osteoporosis outnumber deaths from cancer.


6. The only bone that is not attached to the skeleton (that is, it does not communicate with the skeleton in any way, but grows into the muscle layer) is hyoid bone.


7. It is considered normal in an adult the mass of the skeleton is 15-18% off total weight body.


8. Are you anything heard about Gorham's disease? This is a congenital ailment that was first described only in 1954. mysterious and rare disease characterized by proliferation of blood vessels, which leads to the destruction of bone tissue; exact reasons The causes of Gorham's disease are still unknown to science.

Interesting Facts about the human skeleton. Oddly enough, it is not always possible to indicate the exact number of bones in the human skeleton. First, it is somewhat different different people. Approximately 20% of people have abnormalities in the number of vertebrae. One in every twenty people has an extra rib, and men have an extra rib about 3 times more common than women. Secondly, the number of bones changes with age: over time, some bones fuse together, forming tight sutures. Therefore, it is not always clear how to count the bones. For example, the sacrum clearly consists of five fused vertebrae. Count it as one or five? Therefore, reputable manuals carefully indicate that a person has "somewhat more than 200 bones."

But let's see why we need a skeleton.

Basic functions of the skeleton

1. Support. The skeleton serves as a rigid, compression-resistant framework for the body. It helps the body to maintain a certain shape, providing support for all its mass, counteracting the force of gravity and lifting the body off the ground. This makes it easier to move on land. The internal organs are fixed and suspended from the skeleton.

2. Protective. The human endoskeleton (internal skeleton) protects internal organs. The cranium provides protection for the brain and sensory organs (vision, smell, balance and hearing), the spine - protection spinal cord, and the ribs and sternum protect the heart, lungs and large blood vessels.

3. Locomotion. The skeleton, built of rigid material, serves as the site of muscle attachment. When muscles contract, parts of the skeleton work as levers, and this leads to various movements. If you have problems with the spine, check out the article How to fix your posture.
