Very accurate data (and I double check...) I find this tool returns very accurate data on keywords and ads used by competitors. I double checked it by running searches through a VPN, and it was almost always spot-on.

Amazing research tool to find trends in landing page design As someone who looks at thousand of landing pages each month, iSpionage has become my most treasured resource for landing page discovery. As a competitive intelligence tool it's a great way to keep abreast of what others are doing, and to make sure I stay on top of the design trends in PPC advertising.

Save time and money Of all the tools we use, iSpionage has to be #1 when it comes to better understanding our competitors' PPC and SEO strategies. The intel they provide helps us make much smarter business decisions. Bottom line: We save a ton of time and money.

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.

Helped Find New Brands to Advertise I can put any brand on my site. There are many in my vertical to choose from but I cant put them all up. This is a fantastic tool which allowed me to see what advertising efforts my competitors were taking on brands I had no visibility on via the keyword & ad reports.
