When the other business I am involved was launched over 2 yrs ago we ran a google adwords campaign for a month (under the guidance of a google adwords consultant), spent over £250 and got one sale (under £15). About 6 weeks later the business was getting organic search results and monthly sales of over £1500 through those organic search results and they have risen dramatically since then.
So obviously we didn't think it was worth continuing with adwords.
Now my new venture...I started a campaign last week (under my own guidance

) with a daily budget of £5, got a grand total of 38 clicks in 3 days and not one sale. I know those figures aren't enough to go on but how do you measure success? Obviously SALES but are there average CTR to aim for to know you are on the right track without spending a load of money?
Also I know I can improve on the above results esp after reading more about it, but I am just not sure how to know when enough is enough
