linking

What I really need to do now is get some relevant links (reciprocal) - these are really hard to come by, currently I have submissions in some directories ad a couple of links I have managed to blag - watch this space for developments.
Reciprocal links are a very important tool in getting your website ranked, my own links page is fairly heavily populated, but getting these sites to link back has proved fruitless in most cases.

I need to do some spring-cleaning here and clear out some of the non-returned links - then I need to come up with a campaign to replace the useless links with some useful ones..the work never stops
