Also always include a photo in which your face is clearly visible. This is not only useful to the reader, to understand who the host is and how much he knows, who is offering a content, but also to the search engine to understand, through a reiterated schema marking, that you are talking about something that you regularly study in depth and that "it is always you".
The reason why I tell you to use close-up or half-length vk data photos and not a distant photo of you from behind while you admire a landscape is not, again, just a question of relationship with the reader, but also with search engines, which with biometric recognition are able to associate your various "profile photos" scattered across the other channels you use for your project.
today it is no longer necessary. Another useful thing: try to standardize the keywords of your expertise on all the online channels that represent you. If on Linkedin you are "analyst at company x" and on Instagram you are "book lover", on the blog you are "travel blogger", you confuse the search engine long before your readers.
