Hi, Im new in adwords. I have some problems. I dont have any specyfied target. I want to show my ads everywhere, how to do it? I picked some high searchable words like ebay, gmail etc. but its not working. Im in situation that I have cash to spend but I have only 100-200 shows per day.
Sounds like you might be better off running a placement targeted campaign - pick some sites that you want your ads to show on. (though you can't pick ebay or gmail that way - but you can't do the way you're trying to, either)
Are you wanting your ads to appear on these? If so, simply turn on "search network" in your campaign. I do not know what you are trying to advertize but I suspect bidding on keywords like "ebay" and "gmail" you could have problems with poor relevance and high 1st page minimum bids resulting in few impressions. If you want to appear "everywhere" then create keywords relevant to your site - what you are actually selling or promoting - and choose Google and search network and content network. For max exposure on content network be sure to have some image ads as well as text ads.
By the keywords that you are bidding on, i would say that you have money to lose and not money to spend. Why you don't spend some time learning how PPC works and than start spending your money.
I read somewehere that only one ad for domain can run in same time, is it true? I tan to put many different ads, with links to same domain, but other directories, for example: www.xxxxxx.com/xxx1 www.xxxxxx.com/xxx2 www.xxxxxx.com/yyy1 etc.
