Google Ad words can be great for business. Take into account what keywords your going to bid for. Will $25 post you in the top three Once they click on your site how long is their hang time. Do you have a way to track conversions? For instance: I have one key word that we bid $ 8.00 per click for up to $100 a day. However, the conversion rate is high. I have other key words we only bid up to $2.50 still good key words. However, conversions are a less. I have a marketing company that manages my google ad words campaigns. I can see who has been to my site, how long they stayed, what search engine they used, did they convert. Please note: I use this for my another company we own.
