As I pull my keyword volumes, I put them into an Excel spreadsheet and I create one very large list. I don’t pay much attention to volume at this point, because I don’t want to get distracted. I just keep loading up the list with keywords, volumes, and competitiveness.
Now that you have all the keywords and volumes get some rest, to think from the beginning with a new aim in mind, if the list is really long then remove the keywords that are very low at volume, it all depends on product and targeted market.
