Keyword deletion strategy

I've been doing quite a lot of reading up about about AdWords, and the general principle is you create a list of keywords, as many as you can possibly think of that are related, and then remove keywords that aren't performing well. But how do you determine that a keyword isn't performing? I mean, so long as people are clicking on it then what's the harm in just letting it run? Why bother deleting it?

 

Google analytics will show you what keywords draw people to your site, plus adwords/analytics will tell you the amount of time the person spent on your site. It's good to know what keywords aren't working because you spend money on adwords, so it's better to spend the money on keywords that give you a return.

 

There isn't really any need to think about the keywords, select the relevant categories to the website content

I compare the keywords CTR against AW Stats
I retain anything over 10% and suspend anything below 1%

Obviously trends change so you need to monitor over various periods; week, month, quarter
As an example I have to enable some keywords depending on the season

 

If you use the ADwords Conversion stuff, then you can clearly get an idea on which keywords are performing better and which one are being converted into sales or lead. This is the best tool to find out which keywords need to be removed from the list.

 

And we didn't get the good effect what they have tell us. and we are using it later to accumulate the focus, and be better in future!
