Here is from my own experienced 1. You know that reciprocal still working and you can get great results with this strategy as long as you don't get reciprocated too hasty for each month. about not over 50 links, from theme related sites also. 2. Free new directory with PR0, even not indexed still have some value for your site, as long as you don't get too hasty and use all same anchor text for all incoming links. 3. E-mail for link exchange still working, even in junk folder. If you have quality site then easy for negotiate in link exchange. 4. links page with many outbound link still have some valued in SE eys as long as they linked to quality one.
