Maybe is my mistaken....never research much... already spend quite a lot money for outsourcing etc on these sites.. my main site is hardware tools contain two full review of power drills. than i have few sites using sub domain " hardwarezoneshop" on electronics , promoting electronics stuffs. I have been monitor ....it over months highest click actually is today 52 clicks.. many fellow IM comment my site ok just that electronics niches is too competitive...people usually must well visit those big boys sites to buy electronics... now I don't know how....should I continue ? or just close down ..concentrate one affiliate program? which more on marketing.
