I am looking for a list of top link building firms. Anyone know of such a list or has worked with a company they would recommend? Thanks.
Try this link. I recently saw canadianeh posting list of directory submission companies, you might want to check that out.
We've used a few good ones in the past. Really depends on what type of link building you're in need of. Super high quality manual or more automated postings in social networks, forums, directories, etc. I always opt for the first -- spend the money on high quality ones -- they will prevail in the end You can also consider viral link baiting and get a few excellent writers who are geared for this type of link building via content. Hit me up through PM and I'll give you a few names.
