My blog site is work at home jobs which is 2nd page on Google.com. I checked search volume for this keyword at wordtracker(daily over 1000) and Google Adverd keyword tool(daily=27100/30=903---[exact] keyword search). My site was 12th place at Google.com. But, I had very few(1-2 visitors from "work at home jobs" per day) visitors for the above keyword. Because of this situation I am boring to optimize my site to Google.(To optimize for search engines we have to work hard. when we not receive the expected result, mentally we going down). Actually what is this situation? Are these both tools incorrect? Please advice me.
You should target other keywords related to that keywords like work from home, work at home, data entry work from home, online jobs from home which gives traffic to your site. Use few long tail keywords which brings traffic to your site.
