Yesterday, I shared a number of different PPC tools  that will help with building and tracking performance in your account. This time around, I have a few new tools and sites that will help you check some performance statistics of your competition and see how you compare to them. I am also sharing a few tools that I have found myself needing quite a bit when managing my accounts and working with various clients.
PPC Competitor Analysis
SpyFu : SpyFu allows you to do in-depth research on competitors and see what keywords they are bidding on, as well as ad history, average position , and potential daily spend ranges. Whether you want to do in-depth research on a specific competitor or to see everyone that’s bidding on your top keywords, SpyFu lets you do it all. It offers a free version which allows you to see the top 10 keywords from a competitor or stats on a specific keyword, but also has a paid option with even more features.
Compete.com: This site allows you to see some basic analytic stats on your competition – monthly unique visitors, changes in monthly traffic, competitiveness, and more. It’s very useful for gauging how your competition is growing and who you need to focus on. It offers a free version and a more in-depth version for a fee.
Alexa.com: Alexa is very similar to Compete, but offers even more stats, including some search analytics. It provides the top 10 search queries, daily search traffic over the course of last 30 days, and it even gives you overview stats, like how many keywords they are targeting in Google and Yahoo/Bing. Additional features include demographic info, contact info, and overall traffic stats. While there is a paid version of Alexa, the free version provides a significant amount of data, so you might not even need it.
Tools for PPC Landing Page Creation
Unbounce : Unbounce provides multiple, easy-to-use templates for a variety of different landing page types, including lead generation and mobile apps. Create simple and beautiful landing pages  with ease!
Shopify : Similar to Unbounce, but for e-commerce sites. Create great-looking store fronts and product pages!
Miscellaneous PPC Tools
These tools are especially useful if you manage multiple PPC clients  in different time zones.
