Google launching “Contextual Targeting Tool” to all advertisers, accessible from the Opportunities tab in AdWords account, and that will help you create contextually-targeted campaigns more easily and quickly, while generating more clicks and conversions for your campaigns.
You’ll still need AdWords Editor to implement the ad groups in your account for now. However, this requirement will be lifted and you’ll be able to implement new ad groups directly from your AdWords account in the coming months.
CTT automatically builds keyword lists that can be used to show your ads on relevant webpages in the Google Display Network. Tightly-themed keyword lists are the basis of effective contextual targeting, and with CTT, you no longer have to build them manually. In minutes, you can build dozens, even hundreds, of keyword lists, scaling your campaign performance while ensuring accurate targeting for your ads. This means you can get more clicks and conversions for your campaigns and you can do it more quickly.
How do I use it? With CTT, simply type each product category into the search box, and the tool will automatically generate tightly-themed keyword lists for you.
These new ad groups can help you get additional traffic and sales, as you may not think of creating them when manually building out your campaigns. Along with the new ad groups, the tool provides suggested bids and predicted placements to give you an idea of the types of sites in the GDN where your ads can appear.
