Watch this video What is AdWords?

AdWords overview

No matter what your budget or how little time you have, you can reach new customers and grow your business using Google’s online advertising program. With AdWords, you can choose where your ad appears, set a budget that’s comfortable for you (there’s no minimum spending commitment), and easily measure the impact of your ad.

Reach people exactly when they're searching the Internet for what you offer. Your ad can appear on Google and its partner websites. With cost-per-click bidding, you're charged only when someone clicks your ad.

Benefits of advertising with Google

A few important things set AdWords apart from other kinds of advertising. Using AdWords, you can:

• Reach people at the precise moment they’re searching for what you offer
• Your ad is displayed to people who are already searching for the kinds of products and services you offer. So those people are more likely to take action.
• You can choose where your ad appears -- on which specific websites and in which geographical areas (states, towns, or even neighborhoods).
• AdWords reaches 80% of Internet users in the US. That's a big audience.

Example

Let's say you run a bakery near Boston. Set your ad to appear to customers in just that location, and when someone living or vacationing there searches Google for "blueberry muffins near Boston," they could see your ad and click it to connect to your business.

• Control your budget
• With cost-per-click bidding, you're charged only when someone clicks your ad, not when your ad is displayed. There are a variety of bidding options you can choose from.
• You decide how much or little you want to spend monthly, and you’ll never be charged more than that amount.
• There's no minimum spending commitment.

• See exactly what's working in your ad, and build on it
• View a report of how your ad is doing -- see how many new customers connect to your business from your ad, where they're coming from, and other details.
• Use AdWords' tools to edit and improve your ad, and increase the number of potential customers who contact your business.

It's simple to get started, and it's easy to pause or stop. No strings attached.

How Adsense Works

How AdSense works

How AdSense works

The webmaster inserts the AdSense JavaScript code into a webpage.

Each time this page is visited, the JavaScript code uses inlined JSON to display content fetched from Google's servers.

For contextual advertisements, Google's servers use a cache of the page to determine a set of high-value keywords. If keywords have been cached already, advertisements are served for those keywords based on the AdWords bidding system. (More details are described in the AdSense patent.)

For site-targeted advertisements, the advertiser chooses the page(s) on which to display advertisements, and pays based on cost per mille (CPM), or the price advertisers choose to pay for every thousand advertisements displayed.^[12][13]

For referrals, Google adds money to the advertiser's account when visitors either download the referred software or subscribe to the referred service.^[14] The referral program was retired in August 2008.^[15]

Search advertisements are added to the list of results after the visitor performs a search.

Because the JavaScript is sent to the Web browser when the page is requested, it is possible for other website owners to copy the JavaScript code into their own webpages. To protect against this type of fraud, AdSense customers can specify the pages on which advertisements should be shown. AdSense then ignores clicks from pages other than those specified.
