Thanks again for all your input, ssgumby reminded me of the use of negative keywords, I will have to brush up on that before I try it out.
I guess I'll just have to jump in at some point, I will bear in mind some of the things that came up here. I'm really tight with money so will hopefully find a way for maximum ROI.
My visitor number are pretty low so it would be a good way to test if my checkout procedure is any good.
What I'm going to check before I start are:-
Checkout looks good
Find cheap longtail keywords
Any other suggestions, let me know.
Is the conversion rate generally higher for paid ads? I guess the people who click on them must have a specific interest in buying.
My current conversion rate is only a few percent, but maybe the content bringing people in isn't optimal for generating sales.
I feel all warm inside being featured on the homepage!
