It's a WordPress website and the home page DOES have a title. I have never heard of this Topic and my WP programmer searched in his website and didn't find anything that was called Topic.
I checked one of my websites and the Topic was also a weird choice, but my Title was fine.
I told him that these free tools are not perfect, but he was still concerned.
The question is do either of these affect his SEO? It would help me to get another answer to tell him.
