uniquely way to make a back link

one of the potent way to get a better place in search engine is search for many links this is ussual in SEO technique . but did you aware something ? only backlinks from blog with same niche will help your blog to have a better place in search engine. maybe a way like submitting your blog to web directory is common but i have an unique way . a blogger who submit his blog to web directory or link exchange site is ready for placing a link to another blog , am i right ? so why dont we submit our site to their blog . you are lucky if the blog has a link exchange page or giving the blogger e-email or his IM . but what if the site do not have this kind of service ?
try this www.link-exchange.ws in this site we can have e-mail address of another blogger
i have tried it and got a few links hahaha
