I have been doing keyword research for quite some time and find my current method to be somewhat exhausting. I currently search on Google Adwords Keyword Tool for a keyword phrase related to my niche, checkbox each keyword phrase with at least 3000 Global Monthly Searches, download them onto an excel spreadsheet, and perform optimized Google searches for each one with hopes to find one with less than 10,000 optimized search results(using "...."). Minus a software, is there a more effective way to do this? Please advise.
Thanks in advance
