Improve your blog's Google ranking!
Having few or no comments on your blog, irrelevant ones, replies written using poor grammar, or full of spelling errors does nothing to help with your SERP (search engine results page) placement, nor your PR (page rank).
I will read and then comment 20 times using different identities, complete with email addresses, website URLs, Facebook ID, Pinterest, etc. so each comment looks to be from someone different.
IMPORTANT: If it is required that I must register each identity, the extra for doing so must be purchased. Sorry, but no exceptions because having to register multiple times is very time consuming.
