A Major Change in Google Algorithm towards blog comment

Hi Friends

You have noticed that from recent few days, do follow blog comment posting are not making huge impact in your SERP.

Reasons:
1) Because maximum people do not care where they are posting their comments.
2) Whether there are a lot of comments posted in respective blog[maximum google consider 10 different links from a blog]
3) Whether blogs are related to your website or not
4) Whether the comment which you are posting are marked as SPAM.
5) You are posting comments in low page rank blogs.

Solution:
1) Try to post comments in those blogs which are related to your keyword or niche.
2) Do not post comments in a spammy blog.
3) Do not use same comments every where, make the comment more specific.
4) More concentrate on above page Rank 1 blogs.

I've been thinking the same thing - maybe this one was rolled out in G dot com dot au because I've been trying to rank a site for weeks and have #1's all round the world except where I need it - it's sitting mid 20's here in OZ.

The above site is prettty low competition and should by all rights be #1 if not top 5, just with SB alone, which is all it's had used on it so far.

I'm throwing a few hundred articles at it to see if that makes a difference.
