I realy dont know what to use for keywords research - AdWords or Overture? The difference in search count and synonyms are huge for a few of my keywords. Help guys!
Are you specifically looking for free tools? How about Digitalpoint's keyword tool? Best tool: www.WordTracker.com
I only use one tool, Trellian. The best $600 a year I ever spent. (yes, that's a shameless affiliate link but they really are the best)
about 2 months ago i use overture, but now there is something wrong with that, so i use adwords to study new words.
WordTracker, Keywords Analyzer, Keyword Elite - these are all good. They each have their strong points.
I actually use the DP tool. Does everything I need it to... http://www.digitalpoint.com/tools/suggestion/
I use the DP tool + Google Search to fill a spreadsheet with selfmade (and secret ) formulas. Then I sort that spreadsheet to view the better keywords .
www.keywordcountry.com is my favorite, if your looking to do niche research its the easiest tool to use, its the most expensive but worth it.
Has anyone tried this one before: http://www.seomoz.org/tools/kwtool.php I'm going to try it out myself and let you guys know how it is...
