I've tried joining relevant groups on Facebook and I tweet most days, but only have a few followers/friends on each after a couple of months.
I keep hearing how brilliant they can be to promote a website but both seem to be a heck of a lot of work for virtually nothing for me.
I'll end by saying I'm not completely useless with social media, Linkedin works very well for me, sending me 20% of my daily site traffic.
Specific practical advice please. Thanks.
