A link to another site is hidden in the text, or its address contains a spam word such as casino or essay.
Hidden links are usually not put there by the owner. They can be left by an old supplier or by a hack, and sometimes stay for years. Google can penalise a site for them. Snaglist only reports what it sees: whether a link is wrong is for you to decide.
For links to other sites in the content, Snaglist looks at styling that hides the link: the text colour without an underline, or a position off-screen. It also looks for a short list of spam words in the address.
Snaglist reports this as a warning. It costs 15 percent of the page in the health score. Fix it before your next crawl.
In the report for your client this appears under the heading "Suspicious links on your pages". When everything is in order, the report says: "No suspicious links in your texts".
