my secret app for all campaigns While my skills more in CRO optimization I think about iSpionage as a great tool for the outgoing a/b testing. The only team that grab the landing pages and showcase them for you to study and learn from. In additional to campaign research having these landing page in place 100% improve the performance of the campaign. I would recommend this tool for anyone who might want to dive into conversion funnel and not just research keywords and clicks!

Satisfied long term user I've been using Ispionage since February 2012 and have been extremely happy with the service. I mainly use it for keyword research where it helps me shortcut the process by seeing what keywords competitors are bidding on.

Great Product for Monitoring Competitors in PPC I have used this product for several months and I can recommend it to people looking for help in monitoring their PPC Campaigns. Solid product and great team in place for your needs!

Provides Critical Data for CRO As of the writing of this review, iSpionage is the only tool tracking competitors' A/B tests. It shows when competitors launch new page variations, when they stop their tests, and which variation won. That is critical information for any conversion optimizer. Well done! They do a good job continually improving functionality, which is appreciated by their clients and important for their business. I've met some of their team members in person, and they're all very knowledgable and helpful.

Great Software, Great Company When it comes to analyzing the PPC data of your competitors along with your own key metrics, you can't beat iSpionage. There customer service is top notch as well. This is am amazing for competitor research and highly recommended.
