What does citation flow measure?

Citation flow specifically measures the quantity of backlinks pointing to a particular page or domain, which relates directly to option A: "How many links in general there are to a page." This metric provides an understanding of the link profile size, indicating a website's potential strength based on the number of links, regardless of their quality or authority.

While it's important to note that having a high citation flow can imply that a page is recognized and referenced by others, it does not account for the quality or authority of those links, which is where concepts like trust flow come into play. Therefore, when evaluating citation flow, the focus is solely on the numeric count of links leading to a page, making option A the most accurate representation of what citation flow measures.
