In addition to the Google AdWords keyword tool, which tells advertisers which keywords are most popularly used as search queries, Google not long ago introduced its Search-based Keyword Tool.
Search-based Keyword Tool operates the reverse way how Google serves pages based on a user’s search query. So instead of keyword inputs, Search-based Keyword Tool accepts web pages as input parameter and processes it (along with optional words or phrases) to display which keywords potential customers or visitors are using to reach your site.
In case you are logged in, you will be able to pick which websites to analyze from the “Website” field in the image above. Also, the tool will display the keywords that you haven’t used yet in your campaign. In other words, this tool will tell you what keywords you are potentially missing from your existing campaign.
This tool, however, is not limited only to advertisers. It is also useful to those that have websites but have no AdWords accounts. The Search-based Keyword Tool can help them figure out which keywords people use and probably what webmasters should also be paying attention to.
By entering your desired website, related keywords and pressing the “Find Keywords” button, you’ll see page similar to the following image.
On the left-hand side, we see a set of categories associated with the keyword(s) entered. This is useful if we want to focus on certain areas.
The big part of the screen displays the keywords, along with the monthly search volume, level of competition and suggested bid amount. These data are similar to the Google AdWords Keyword Tool. Since I am not logged in and could enter any site (including the ones I don’t own), there’s a limited number of keywords displayed on results. Clicking the magnifying glass symbol will display Google Insights for the keyword. Google Insights reports the seasonal and regional interest for the keyword.
The Ad Search Share information isn’t disclosed in this case but for logged users, it will show the percentage of time your ad will be displayed when you bid for the keyword.
I don’t think this tool will render previous tools irrelevant but should somehow add a new dimension in our keyword research so we will derive keywords based on empirical results instead of guesswork.
