If you have some tools for getting relevant keywords then please suggest here & i am doing ppc in adwords so please tell me how do i generate my sales & How do i increase Quality Score & ROI??
I wrote a whole book on that (first link below). This after managing many existing campaigns and realizing most advertisers don't know what's a good keyword for their own business. Even if they do, the problem is writing effective ads. I go into that extensively as well. Oh, then your page has to convert. The ad is the carrot to get them to your site. You have to convince them, close the sale. Most don't do that well and why they barely get a 1% conversion rate. But put all three together well, keywords to ads to site and you will make money.
There's another post in this forum that has good information regarding page quality. Here's the link: http://forums.digitalpoint.com/showthread.php?t=1844504
https://adwords.google.com/select/KeywordToolExternal?forceLegacy=true - this is the best tool fro ppc keyword research.
You say your QS is low, but QS is applied to individual keywords. I would pause or delete any keywords that have a QS of 4 or less and focus on improving the ad text and landing pages of anything 5 or higher. Once you see the average QS of all your active keywords go up, go back to the ones you paused or deleted and try to improve them individually.
