Source: If you would like to know more about “citations” and SEO, this is a great article.
In the article above you will see these two sites. I went through both sites and pulled this list. https://moz.com/learn/seo/citations-by-category and https://whitespark.ca/best-citations-by-category/us/
Another SEO benefit from this posting is that you will receive “backlinks” from each of these sites and those help your content SEO rankings considerably.
