I have been trying to get link exchanges for my site and have mostly been submitting my site to directories that are part of another main site (rather than self-contained directories) and so making sure they are relevant to my site. I see some such directories that have automatic link exchange software and some that say " once you have put our link on your site email us at...." My question is which do you think will more likely result in an exchange and which is quicker? Is there likely to be any difference? I only ask as it takes a little while longer to submit to the latter of the two types but I would be willing to do this to get a higher success rate of link exchanges. My thinking is that if it goes straight to the webmasters email then they are more likely to respond quickly.
