Details: Start with Kombat
1. Enter the domains of at least 2 of your competitors in the SpyFu Kombat fields. Save your domain for the 3rd spot. Click “fight.”
2. The results default to the Ads, so make sure to choose the Organic tab.
3. Click the overlap of your two competitors’ keyword circles. See in the example how you would click where they intersect apart from your domain’s circle. That gives you keywords you don’t already rank on.
4. The results open on the right. The overlapped areas include keywords where BOTH of your listed competitors appear as top 50 search results, but you don’t.
5. Since you excluded your own domain’s keywords in step 3 above, this list is filtered to competitors’ keywords you don’t yet rank on.
6. Export them or open the interactive keyword list that lets you filter, select, and export to Adwords.
