Hi. Could you find the mistakes of these two paragraps? Please, let me see it easily. Thank you so much for your time.

Writing for advertising copy writing is not much different from writing for public relations or reporting. They use the same style and format. Advertisement is controllable. Copywriters usually try to convey positive message of the product to the audiences. Copywriters have to understand and identify the objective and target audiences. Then they can create an idea to sell a product. It is important to concern about the audiences. Copywriters usually come up with questions that make them reach the audiences such as who are the consumers.

Copywriters should sometimes look out of their own window to see what the situation now is. So, they can avoid the same error and create effective advertisement. Advertisers have to identify what medium they will use for specific advertisement. Each medium has its own ability to deliver the advertisement to the audiences. Lastly, this chapter has hints for writing effective advertisement copy which called HUBBA. HUBBA has the five elements that are Heads matter, Use brand names, Be visual, Be brief and Always make a promise.
I have emboldened the area of the mistake so that you can see it easily:

Here are corrections and explanations:

- Writing for advertising copy is not much different from writing for public relations or reporting. -- the second 'writing' is redundant

- Copywriters usually try to convey a positive message of the product to consumers/customers.-- You had the right idea but the wrong article. Audiences listen; spectators look; customers buy.

- It is important to concentrate on the customers.-- Good! Or: 'be concerned about'.

- Copywriters should sometimes look out of their own window to see what the situation now is, so they can avoid the same error and create effective advertisement. -- the conjunction was the problem: don't start a sentence with so.

- Lastly, this chapter has hints for writing effective advertisement copy, which are called HUBBA. HUBBA has five elements, which are named Heads matter, Use brand names, Be visual, Be brief and Always make a promise. -- A non-restrictive (non-defining) clause should be set off by commas, begin with which, and have a verb.

Also:
