Why are the numbers different from the Google AdWords tool numbers?
KeywordIndex does not show the number of searches for a keyword on Google. It shows the number of searches that has been done in the sample to which we have access. The numbers do not reflect every single search on the Internet but they show a good sample of the keywords that are used on the Web. The keyword tool in Google AdWords returns rough estimates for the number of searches and it also focuses on paid keywords. If you check the number of searches in Google’s keyword search tool then you’ll find that many keywords have exactly the same number of searches. For this reason, 76% of professional search marketers do not trust Google’s keyword tool (click for source). KeywordIndex offers you an alternative to find the best keywords for your website. Tip: IBP’s keyword manager can access both Google AdWords’ keyword tool and KeywordIndex in the same user interface. It also enables you to optimize the found keywords for your campaigns.
