I had most of my sites removed from MSN recently. From what i've heard it's likley due to putting links on my sites to those that are not "related". So my question is what does MSN now consider "related". If I have a site about Honda in California is sites from automotive or car related sites good enough or does it have to be Honda related? Further does it have to be California related or will Honda suffice?
If you haven't done any 301 work, it could be your KW density.
From another post: After August 06 update: After much testing, I lowered KW density...all my pages are back up and ranking well on MSN. *Here is what I found...use KW no more that 2 times in Description Meta Tags. *Keep overall page density under 3%.
DON'T over optimize Meta Tags or Page Body... choose 3 or 4 KW's in your Description and use no more than 2 times...all others 1 time. Use the same KW's for page body and keep in the 3% range. All other page body KW's keep at 1% to 2%.
Yahoo also seems to like this density...traffic has increased. Google is not a big traffic generator for us yet, so I can't say. If Google is your main SE with plenty of traffic, I wouldn't touch a thing, however if MSN and Yahoo are your main SE's...the above worked well for us. Hope this helps. Fish Texas
