i have a blog with pr3 and it gets more than 100 uniques per day.Can i put links to my other blogs in this blog in the footer(other blogs are of different niche).Will this help in optimizing my other blogs which dont get that much traffic?or will it impact negativley?
Footer links don't have much significance but it would help nonetheless. Since the other blogs are from different niche, I am assuming that you would not be able to link them in the content of the blog that you are talking about.
It will help put you as SERP point of view. if you are getting targeted traffic than they only interested in your present blog which you have other blog so.....
yes you can do it. Your other blogs will get some good SERP and build good back links for those blogs.
It would be somewhat useful to interlink all your blogs, preferably using 3 way links if that doesn't get too confusing!
Yes you can do it but put the links within the "content" not the "header" or "footer". Google likes links that have text around them.
Yeah, I'd have to agree with everyone, that footer/header links will be beneficial, but not in a huge way. I'd suggest trying to mention words that are related to the other blogs, in the content of your current blog, similar to what catanich said. Google does prefer links within text. It sees it as more natural. Good luck!
I personally don't think linking to other sites which are not related can do any good to your site....Its better to do link exchange with related sites..so why not you try 3 way link exchange here in the link exchange section??
