i have seen many bloggers using viral link post. they use two types viral link cloud and viral link matrix Viral link cloud : contains some anchor text and its hyperlinked viral link matrix : Contian only *(or some specific symbol) as anchor text. can you tell are they usefull??
"viral link cloud" seems like an oxymoron... I've never heard of a link cloud going viral, or helping much of anything...in fact, I just tried looking for "viral link cloud" and came up with nothing (though this thread will likely pop up there soon). Can you define it, or maybe point to a definition? Oh no, wait... found it. Please see this thread: Link Trains, what do you think? it's a train wreck waiting to happen, I'd stay FAR away from them, unless you try it in moderation (say with a self imposed limit on the number of links).
Well, a link is a link, even if a symbol is less effective than your site's keywords, that's true...but it isn't worthless, same for linked banners/pictures.
heres the example * above * is used to link to some of your post. i can create a line full of these asterisk in small space many links
The more links on a page, the less value each of those links has. Having a fewer amount of good quality links will help you more than lots of poor quality links.
