Because of the new Google update (3/5/2012), it is now recommended to do the following when it comes to anchor text variations:

50% of your anchor texts should be your primary keyword.

50% should be 3-5 secondary keywords.

Example:

Primary Keyword:

Money Making

Secondary Keywords (LSI):

Making Money Fast,

Making Money Ideas,

Make Money Online Today,

Make Extra Money Online,

Make Quick Money Online

If you do this, you will be successful.

If you do not do this, you may be penalized by the new Google update.
