I ran a keyword search to add links, and few or no links were added. Also, SEO Wizard and Link Analyzer are returning very few links. Why?

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.
