This error message will sometimes occur when using the Link Analyzer or SEO Wizard, or when adding links by keyword search. This occurs when there are no results returned by the search engine that LinkMachine is using to search with. The error message is no cause for alarm, and will not result in any problems. It does mean however that no results were found for a search, and there can be several causes for that.

If you have entered a Google Web API Key under Site Settings, try again after removing that API Key. Google has changed the results of their Web API so that it returns far fewer sites than a direct search of Google returns, so LinkMachine generally finds many more links when it is not using a Google Web API key. Sometimes when an API Key is present, Google will return zero results to LinkMachine, which can cause this error message.
