Hey guys I have been using keyword discovery for my campaigns . Its just ok .It does gives you options buy I feel the long tail is left out .Can anybody suggests a better one or any other reviews about keyword discoveries will be great .
Here's a review: Keyword Discovery Review If that didn't work well for you, I suggest either Keyword Country or Keyword Spy. For good long tail keyword research you may have to use tools that analyze competitor sites or competitor ppc campaigns. You may not find much search volume data on them, but you can target them with seo and/or ppc to test effectiveness.
