A blog is a website that contains content that includes text, images and multimedia, and entries are displayed chronologically. Using corporate blogs, businesses connect with consumers, conduct personalized marketing communications that result in increased consumer trust, and help gather information about consumers. Running a successful company blog means that the blog is regularly visited by a significant number of people who are satisfied after visiting it, who comment on the content of the blog and return to it again. Companies that run corporate blogs encounter numerous challenges that they have to overcome, some of which are: responding too quickly to negative comments from blog visitors, fear of criticism from visitors, the person writing the blogs does not have enough knowledge about the topic he is writing about, after the blog post is published, it is no longer checked what is happening on it, the blog is written by people who use formal business language, the blog does not have a defined flow or rules of communication, irregular updating of content, absence of prominent communication rules, publication of posts with errors, etc. In the work two corporate blogs will be listed and displayed, Mirjana Mikulec's Studio for Interior Design/InDizajn Mirjana Mikulec blog and Escape Digital Agency's blog. Considering the significance that blogs have today for the business of companies, with the emphasis on the fact that communication and relationship with customers are achieved and maintained through them, companies will continue to use them in their business in the future, and it is to be expected that blog visitors, as they develop technology, have a bigger and more important role in creating and sharing content on blogs than they do today.
