The Tools tab provides direct links to a variety of AdWords account tools. Use these tools to monitor and make changes to your account, ads, ad groups, and keywords.
Here's a screenshot of the tab, along with explanations of the tools you'll come across. Just click the name of an individual tool to get an overview of what it can do for you.1. Change History
The Change History tool displays changes you've made to your account for the last two years. With easy access to your account history, you can make sense of performance changes, and keep track of how you've managed your account in the past.2. Conversions
The Conversions section can reveal what happens after people click your ads. Do they purchase your product? Or sign up for your newsletter? To track this information, simply use a free tool called Conversion Tracking. By knowing more about your conversions, you'll also understand which keywords are good for your business, so you can invest more money in your best words and boost your ROI.
After you've set up Conversion Tracking, you'll find a complete summary of your conversion data here, to complement the reporting you'll find within the Campaigns tab.3. Google Analytics
Google Analytics shows you how people found your site and how they explored it. Using this information, you can improve your website's ROI, increase conversions, and learn how to provide a better experience for your customers. With Analytics, you can also set up goals (website pages that serve as conversions for your site), and import them into AdWords. Some examples of conversion pages are a "thank you" page after a user has submitted information through a form, or a purchase confirmation page.4. Keyword Planner
Keyword Planner helps you build new Search Network campaigns or expand existing ones. You can search for keyword and ad group ideas and even see how a list of keywords might perform. That's important because the keywords you create for a given ad group are used to target your ads to potential customers. In other words, good keywords can help you show your ads to the customers you want, when you want. Keyword Planner can also help you choose competitive bids and budgets to use with your campaigns.5. Display Planner
Display Planner is good to use if you've chosen to run ads on the Google Display Network. On the Display Network, you can target your text, image, video, or rich media ads to show on specific sites, pages, apps, or videos across the network. Display Planner helps you plan your Display Network campaigns by suggesting keywords, interests, topics, placements, demographic groups, and remarketing lists to target. Along with all the ideas it suggests, you'll see estimates for cost and reach based on historical data.6. Ad Preview and Diagnosis
Use the Ad Preview and Diagnosis tool to search for your ad just like you would on a regular Google search results page. This is an easy way to check how your ad appears, and you get the exact same results as a Google search without accumulating any impressions (so there's no cost to you). If your ad isn't showing, the tool will explain why and provide steps to help you get it up and running.
