URL receives both follow and nofollow internal links issue means that the URL has a mixture of follow and nofollow internal incoming links.
The nofollow attribute can be added to an internal link to instruct search engine crawlers not to crawl the linked URL. This also means that indexing signals such as link equity (e.g. Google’s PageRank) are not passed through the link to the linked URL.
If a given URL receives nofollowed links, this is usually a deliberate act, either because the website owner does not want to pass link equity to the linked URL, or they do not want search engines to crawl it.
However, if even one other URL links to this page using followed links, this can negate the affect that the website owner was trying to achieve with the nofollow.
