my all ad words campaigns not approved bcoz .all keywords are showing rarely shown due to low score.plz tell me how to solve this problem
Try using the Google keyword tool located at http://bit.ly/i2FDKJ . You can enter the URL of your website and it will suggest keywords based on the site content. It's not perfect, but it is a start. Best of luck, 7searchGuys
Whoa, you've got a lot going on here. If Google didn't approve your campaigns, it's because they're violating the terms of service in some way. I'm not sure what you mean by "not showing due to low score." That could be "low search volume" or "low quality score," but not low score. If it's low quality score, it means that your keywords having nothing to do with your ad and your website. Make your ads and website include more of the keywords. If it's low search volume, hit up the keyword tool like 7searchguys said.
If you need better keywords, maybe you can check your competitors adword campaigns to see what they're using?
