There is new breed of tool which internet marketers and affiliates are now starting to use to help improve their online profits and ROI.

PPC ad spy tools allow you to gather information each day about pay-per-click (ppc) ads which appear on the results pages from the major web search engines such as Google, Yahoo and MSN.

You enter the keywords that you want to find adverts for in to the ppc ad monitoring system and the matching ads from the search engine results (scanned several times a day ) will be stored in the system for subsequent analysis and research.

After several days the system will indicate which of the ads found are likely to be the ones that are profitable.

This will therefore tell you which ads and therefore which keywords are making money for your competitors.

Simply use the same profitable keywords and same ppc ads and you should be able to make money just like your competitor.
