Upper & Lower Case Anchor Text

[AnkitMaheshwari]

I was thinking will it make a significant difference in Google rankings if I use different variations (upper/lower) apart from singular/plural of a keyword during link building.

eg: Blue Widgets, BLUE WIDGETS, Blue widgets, blue widgets being used as Anchor text to target a page.

Thanks in Advance.

I've got no data to back this hunch, but I would guess this would be worse than just being up front about identical IBLs. It looks like you are trying to fool google (intent to manipulate), rather than innocently building identical links.

I have not tried this myself, however I have seen different results (websites) for the same keywords when typed in All caps and otherwise.
