Today there are few people (among those who are friends with the Internet) who have not heard of such a specialist as an SMM manager. However, only a few will be able to answer the question “who is he and what does he do?” And even among employers posting vacancies looking for this “fashionable” professional, there is no clearly defined understanding of the tasks and responsibilities of an SMM specialist. However, this does not stop them from conducting interviews and hiring people responsible for promotion on social networks, and from applicants calling themselves experts in this field and putting forward requests that sometimes shock even generous “salary providers.” So who is he, this unpredictable and so necessary SMM manager in our time?

SMM and SMO - what is the difference?

Before we talk about the profession itself and its representatives, let’s first understand this: what is SMM? How is it different from SMO? what role do these components play in promoting a website/product/company on the Internet?

If we compare it 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 social networks.

The essence of SMM activities

Aimed at promoting goods and services posted on the website, in social networks, on forums and blogs in order to make them recognizable and thereby attract target visitors - consumers, clients, etc.

SMM activities are 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 an external platform and consists of communicating with a potential audience, attracting new subscribers and future clients to the site, as well as smoothing out conflicts that arise around the company/brand/product through competent responses to negative reviews/comments.

Thus, we can say that SMM is effective tool creating a positive image of a company or product, allowing as soon as possible convey information about it through active work on social networks.

So, for example, he should not be involved in one-time advertising and PR campaigns (this is the responsibility of PR and online advertising specialists) or drawing up proposals or managing clients (this is the direct task of the account manager).

His responsibility is to achieve specific tasks set for the commercial platform (groups, pages, blogs) by communicating with the target audience in the virtual space. In this case, the tasks can be different: sales, increasing brand awareness and product memory, improving the company’s image, etc.

Thus, we can distinguish two main areas of work for a social media manager:

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

What does an SMM manager do during the day?

Considering 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 organize it correctly. So, throughout the day, an SMM manager needs:

What kind of SMM specialist is he? Qualities required by a professional

Besides, good specialist must be technically savvy and proficient in social media tools. So, it would not be superfluous to understand analytics and SEO, programming, understand (at least basic level) Social Media API.

1. Male and female skeleton: what's the difference? In fact, there is no significant difference. Some bones differ only slightly in length and size. For example, women's rib cage already masculine, and the pelvis is wider. In men they are more pronounced brow ridges, and women tend to have shorter and thinner limb bones.

2. The smallest and lightest bone in the human skeleton is located in the middle ear. Auditory bone stirrup, or stirrup has a mass of 2.5 milligrams and a size of 3−4 millimeters.

3. In turn, the longest bone is femoral. It is about 27% of overall growth person. In addition, the femur is considered one of the strongest (along with the tibia).

4. The legendary American stuntman Evel Knievel set a record that hardly anyone would want to break. By 1975, Knievel had suffered a total of 433 fractures. Fortunately, by the 80s, the stunt performer successfully completed his career and lived a fairly long life.

5. The most common disease affecting the human skeleton is osteoporosis. This disease is characterized by decreased bone mass and increased fragility bones. According to WHO, in Europe the mortality rate from osteoporosis-related fractures is exceeds the number of deaths from cancer.

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

7. It is considered normal for an adult skeletal mass is 15−18% of total mass bodies.

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

9. It is generally accepted that there are 206 bones in the body of an adult. However, huge amount people have “anomalies” and their own characteristics, therefore exact number bones are very individual and cannot be counted.

Interesting facts about the human skeleton. Oddly enough, it is not always possible to indicate the exact number of bones in the human skeleton. Firstly, it is somewhat different different people. Approximately 20% of people have abnormalities in the number of vertebrae. One person in every twenty has an extra rib, and men are about 3 times more likely to have an extra rib than women. Secondly, the number of bones changes with age: over time, some bones grow together, forming dense sutures. Therefore, it is not always clear how to count bones. For example, the sacrum bone clearly consists of five fused vertebrae. Should we count it as one or five? Therefore, reputable manuals are careful to indicate that humans have “slightly more than 200 bones.”

But let's figure out why we need a skeleton.

Basic functions of the skeleton

1. Support. The skeleton serves as a rigid frame of the body that is resistant to compression. It helps the body maintain a certain shape by providing support for its entire 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 to the brain and sensory organs (vision, smell, balance and hearing), the spine provides 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 a site for muscle attachment. When muscles contract, parts of the skeleton act as levers, and this leads to various movements. If you have problems with your spine, check out the article How to Correct Your Posture.

15 Interesting Facts About the Skeleton

7. The strongest bone is the tibia. It is the bones of the legs that hold the record for strength, since they must not only withstand the weight of the owner, but also carry him from place to place. Tibia in compression it can withstand up to 4 thousand kg, while the femoral one can withstand up to 3 thousand kg.
