The problem with only relying on SEO for traffic is that you leave your entire business in the hands of strangers (google). If they change the algorithm, you can die overnight.
SEO is good but it should be one of many ways you drive traffic.
May I ask how much money you have available for use in your marketing endeavors? What you should do will depend on that number.
Honestly?...
First, you need to get your head and finances in order. That might mean biting the bullet and getting some part-time job you don't particularly want to do. You need to get back into the 'working' frame of mind, and nothing does that better than working for someone else. It'll remind you that you'd rather be working for yourself, and make you double your efforts. It'll also provide some cash for toolz and a marketing budget.
Thanks to all who took the time to reply.
jascoken i have taken on board what you said, i have tried to find a part time job to get some money in, but where i live in the countryside there isnt many jobs going at the moment and at least 40-70 people going for one position even in the lowest paid work but i am still trying to get something.
I have 6 sites at the moment had a few more but these did not work for various reasons, so are you saying the more sites the better rather than trying to get say 2 sites paying more?
