If your site is stay in the top then its good dont worry about that. MSN will change their algo randomly, in the changing strategy it is the father of the google. Outsourcing Sales this is the keyword on which my site was on the top befor some time but now its on the 35 position, even though meta and content are nice you can see this and field sales its another keyword on which my site was also on the top position but now its on 113 position so why you are saying MSN is not changing their algo there is changes are happening
ha ha ha .. MSN is not very good in ranking nor do that keep sites for long time at one place. your rank on msn will be ever changing. Msn is mainly concerned about the number of back links nor the quality of back links. In past MSN showed some great love with blogger.com they were listing newest loan blogs from blogger at the top. Ah I feel MSN more relay on the internal linking as well
MSN search is basically broken. They were making pretty good progress IMHO till the middle of last year, when they had a major update that I actually thought was pretty good and a major step forward, they rolled that update back from unknown reasons and have not had a major update since.. I think MSN has greatly de emphasized organic search as a viable business model.
The owner of the MSN is know that all the seo's making lots of efforts for the google and yahoo and get frustration so he think how we can reduce the frustration of the seo's so MSN decided that if any one website will come on the top then we will put it on the top to see this the frustration of seo's will reduce day by day. because you have at least one search engine on which you can show good ranking to your BOSS...
