What can I do with 400K keywords in a text file? They all come off the main phrase "make money". Adwords campaign is out, I think, unless I can upload all the keywords, make a small bid, and try and catch long tail phrases. Keyword stuffing is out, I think, tho I did see some goofball ranking with a keyword stuffed site even recently. What tool should I be using to work with 400K keywords?
