Use Keyphrase-Rich Hyperlink Text

Hyperlink text is a word or phrase, often displayed in blue with an underline, that can be clicked by end-users to lead them to different webpages.

You can boost the ranking of your webpage by adding a keyphrase-rich hyperlink that refers to an external webpage that is listed in the top 10 search results at Google for that keyphrase. That's because Google will assign greater trust to your webpage as an authoritative source of information for a particular keyphrase if it sees that you are willing to refer your readers to highly ranked webpages for that keyphrase.

For maximum credit, ensure that most or all of the hyperlinks on your webpage included a featured keyphrase. For instance:

Effective: Spaying or neutering your pet prevents the suffering and death of thousands of animals.
Ineffective: Spaying or neutering your pet prevents the suffering and death of thousands of animals. Click here for more information.

You may also include a keyphrase-rich title attribute tag with your link. Title attribute tags provide additional information when a user hovers over the link with his mouse. Some readers use this information to determine whether they want to click on the link.
