I am conducting a link audit for one of my formerly high-ranking pages. But despite reading quite a bit on the issue, I am still quite confused as to how to decide whether to keep or remove a link.
Some links come from directories and social bookmarking sites. I know that generally speaking, you do not want to be on these types of sites, but what if their domain authorities, pageranks, and mozTrusts scores are good?
For example, here is one of my links for "envelopes": http://www.folkd.com/detail/www.jampaper.com%2FEnvelopes
The page itself has no MozRank, MozTrust, or links but the domain has an authority of 88, a MozRank of 6.41, a mozTrust of 6.31. Should I be looking on a page level or domain level basis? It also has over 5 million links, with over two million of those being external followed links. Is the high quantity of links a warning sign?
I also used a free online tool (thesitevalue.com) to determine how much traffic the domain gets. Apparently it receives over 350,000 unique visits daily, so it must be useful to people. This, combined with the fact that we've received 5 visits from the link over the last year (not a lot, but something), makes me believe that the link's intent wasn't purely to "trick" Google. Despite this, I still have a feeling the link could be considered low-quality based on the domain's appearance.
Similarly, some of our links are coming from domains named linkdirect.info, backlinks8.com, tolinkup.com, findyourlink.info, searchengineurl.com, websubmissionfree.com. Is it safe to assume these are harmful links strictly because of their names?
Thank you!
