What is the most effective strategy for determining the credibility of a personal blog?

Researching the credentials of the blog's author is the most effective strategy for determining the credibility of a personal blog. The author's background, expertise, and qualifications provide insight into their authority on the topics they write about. By understanding the author's education, experience, and any relevant professional affiliations, readers can better assess the reliability of the information presented in the blog.

In contrast, evaluating the blog's design may offer some clues about professionalism but does not directly reflect the content's accuracy or the author's qualifications. Checking user comments can give indications of reader engagement or satisfaction but is not a strong indicator of the blog's credibility. Similarly, counting the number of followers can show popularity but does not necessarily equate to trustworthiness or reliability of the information shared in the blog. Thus, investigating the author's credentials provides the most direct and relevant approach to assessing credibility.
