The product I now recommend for competitive research is Hexatrack. It’s not cheap ($147/month for the pro version), but it also comes with a complete suite of campaign creation and tracking tools.

They’ve got very helpful and entertaining video tutorials on the site. The primary consumers of competitive research tools are affiliates, so a lot of their marketing is pitched toward that niche. If you’re in a less competitive space, this tool will be even more valuable since you’ll probably be the only kid on your block with this kind of ammo.
