Anchor Variations
This set of controls can be used for varying the anchor texts of your posts with some general anchor texts. Recently Google seems to be favouring websites with very varied anchor texts in their backlink profile so it could be beneficial to vary your anchor texts with some general anchor texts to appear more natural.
There is a good guide in the guide section of this forum titled Profile Settings Explanations and Examples which gives explanations of what each control does and how to use them best.
