Don't bother.... You will get a ton of requests for terrible sites... non related to yours.

If you then turn on your filter the waulity of sites that link request is garbage.

I have seen more traffic from people browsing the linkmarket site looking at mine then I have seen from actual sites sending traffic.

I say thumbs down on that from expierence.

The most important factor in link building is relevance. As long as you can keep that in mind when choosing a link building company / service then you'll be ok

be careful with the links specially after the recent Jagger updates.

Natural link building should be done.

No Bought links no link farms no Link Networks etc.

Yes.. I try use linkmarket.net
very bad!!
all the request was from sab domain ex: (www.domain.SAB.com)
