Why is nobody buying from my site? Adwords + more Issues

[deviltronics]

Hi

I hope you guys can help. I have a few issues so I hope I have posted in the right section.

My website: www_deviltronics_com

I have finally got the website running and got a load of stock in for it (£10,000 to be exact).

Yesterday and today I have been setting up google adwords as I thought this is the best way to get traffic to it as it is absolutely rubbish in the natural search engines.

I have set up quite a few keywords up in adwords, for example a main one 'Gadgets'. I have put the CPC up quite high so its in the top three. I have had about 100 clicks to the site but nobody has bought anything, not even added anything to the cart. (i have a tracker to want everyone does on the back end of the site).

I have added quite a few adwords and keywords so I can experiment with them. But most are not extortionate like the 'gadget' keyword.

The cost of adwords in a day and half is quite high, £100 without a sale. Is my website rubbish and putting people off?

The 'gadgets' is just an example, i have actually broken keywords down for each product.

I would also like to know why the cpc is sometimes lower than that for what is set. For example something set at 30p per click is actually being charged 20p per click. Why does adwords do this?

I have also made a list of 200 UK shopping directories for which I will be submitting my site to tomorrow, some may be paid for others may not. Apart from this what else can I do for the natural search engines, I haven't really got the time for link exchanges etc.

I also had an agent of lycos on the phone today. I have purchased some space on their site. Basically when you do a search through lycos a banner will appear right at the top, if it is related to the word 'gadgets'. So if somebody types in the search 'gadgets' my banner will appear. If somebody types in 'USB gadgets' my banner will still appear at the top as long as somebody hasn't purchased that keyword and so on. Banner size (which they will design to my liking) will be around 400 x 40. This has cost me a small fortune, have I done the right thing??

Any advice will be greatly appreciated.

Feel free to look at the site and let me know what you think.

(sorry for the essay!)
