5 Steps to getting paid

1. Check your address
Since payments are sent to the mailing address submitted with your application, it's important to confirm the accuracy of your contact information and payee name. If you need to correct any information:

Log into your account at https://www.google.com/adsense

Select the My Account tab.
Click the edit link adjacent to Payee Information and update the appropriate fields.
Click Save Changes to update your account, or Cancel to exit without saving.

For security reasons, you cannot change the Payee Name or Country fields once your application has been approved. If you need to make changes to either of these fields, please contact us and request that we close your account. Once your request has been processed, you will then be able to submit a new application with the corrected payee name and mailing address.

2. Provide your tax information

In addition to confirming your contact information, you'll need to submit your tax information so that you may become eligible to receive a payment from Google. We're required to collect tax-related information from all AdSense publishers, including publishers who are based outside of the U.S. , and we're unable to send payment to you until your information has been submitted. So don't skip this step!

If you haven't yet submitted your tax information, click the Tax Information link from the My Account tab. From this page, an easy-to-use wizard interface will help guide you to the appropriate online forms. You're able to submit most forms online, and we'll give you instructions on submitting any other forms that may be required.

3. Select your form of payment

Depending on your payment address, there may be a number of payment options available to you — we suggest you read What forms of payment are available to me? in the AdSense Support center to learn about each option. Once you've decided how you'd like to be paid, click the Payment Information [edit] link from the My Account tab of your AdSense account. Follow the instructions on that page to select your form of payment. Your payments will be held until you have selected a form of payment.

4. Enter your PIN

Once you've earned $50 in combined AdSense for content and AdSense for search earnings, we'll mail a Personal Identification Number to the payment address in your account. You'll need to enter this PIN into your account before we can send any payments to you. Your PIN will be sent by standard post and will take 2-3 weeks to arrive.

5. Generate $100 in earnings

When your total unpaid earnings reach $100, we'll send you a payment at the end of the next month. For example, if your total unpaid earnings reached $100 during January and you completed the 4 steps above, we would send you a payment at the end of February.
If your total unpaid earnings haven't yet reached $100, they'll roll over to the next month and accrue until they meet the $100 threshold.Payment is disbursed within approximately 30 days of the end of the month — to see the timeline of our payment cycle, read the Payment Timelines section below.

Can I filter the ads that are displayed on my site?

Yes. To create and manage a filter list of websites whose ads you'd like to restrict from showing on your site or AdSense for search results pages, simply log in to your account at https://www.google.com/adsense and click the Competitive Ad Filter link below the AdSense Setup tab. You can create separate filter lists for your content pages and for your AdSense for search results pages. Ads for the websites that you add to your competitive ad filter list typically will not run on your pages, but remember that filtering sites may decrease the number of ads that can appear on your pages as well as decrease your potential earnings.
For more details on using your competitive ad filter, please read the Filtering Ads section of this FAQ.
We also combine an editorial team and filtering technology to maximize the quality of the Google ads on Google and publisher sites:
Review: Across the Google network, ads are reviewed using a combination of human and automated processes before they are shown on publishers' sites. The review process takes into account a variety of factors, including the quality of the ad and whether the ad is suitable for all audiences.
Sensitive content filters: At times, certain ads may not be appropriate to run on all pages. For example, Google automatically filters out ads that would be inappropriate on a news page about a catastrophic event.
Please note that Google does not commit that all ads for the websites that you add to your competitive ad filter list or ads containing objectionable content will be prevented from display on your site.

How quickly will Google ads start appearing on my site?

After you've been accepted into the program and have implemented the HTML ad code on your site, ads will start running within minutes. If your site is not yet in our index, it may take up to 48 hours or more before we are able to crawl your site. Until your site has been crawled, we may display public service ads, for which you will not receive earnings.
Your ad relevancy should increase over time. However, keep in mind that if you make changes to a page, it may be 1 or 2 weeks before our crawler captures the changes and updates our index to provide more relevant ads.
Adding the AdSense for search code to your pages will instantly generate an AdSense for search box. As search results are displayed on Google-hosted pages, relevant ads will appear immediately, if ads are available for the particular query.

How does Google target ads to my website?

Simply put, we provide you with AdSense HTML ad code to place on the webpages on which you want to display Google ads. Then, we take care of the rest by leveraging proprietary Google search and page-ranking technologies to deliver relevant Google ads to those content pages.
We go beyond simple keyword matching to understand the context and content of webpages. Based on a sophisticated algorithm that includes such factors as keyword analysis, word frequency, font size, and the overall link structure of the web, we know what a page is about, and can precisely match Google ads to each page.
Google also offers site-targeted advertising options, allowing advertisers to select specific sites in the AdSense network on which to run their ads. These ads do not use keyword targeting, but rather leverage targeted audiences by allowing advertisers to hand pick their market.
Our technology can also determine the primary language of a page. If your content is in a language supported by our program, AdSense will target ads in the appropriate language to your content. In addition, Google ads are geotargeted to your visitor's location.

What's the difference between AdWords and AdSense?

The Google AdWords program enables you to create advertisements which will appear on relevant Google search results pages and our network of partner sites. To learn more about AdWords and begin advertising immediately, please visit www.adwords.google.com.
The Google AdSense program differs in that it delivers Google AdWords ads to individuals' websites. Google then pays web publishers for the ads displayed on their site based on user clicks on ads or on ad impressions, depending on the type of ad.

What is Google AdSense?

Google AdSense is a fast and easy way for website publishers of all sizes to display relevant, unobtrusive Google ads on their website's content pages and earn money. Because the ads are related to what your users are looking for on your site, you'll finally have a way to both monetize and enhance your content pages. Learn more about AdSense for content.
It's also a way for web site publishers to provide Google search to their site users, and to earn money by displaying Google ads on the search results pages. Find out more about AdSense for search.
The program is free, and combines pay-per-click and pay-per-impression advertising - meaning you get paid for valid clicks on the ads on your site or search results pages as well as impressions on your content pages. So go ahead and try this program. If you comply with our program policies, just complete our online application and select either or both of AdSense for content pages and AdSense for search. One application gets you approved for both AdSense and AdSense for search - you can decide to use any combination of these products on your pages.
We'll review your application and follow up with an email within 2-3 days. If you are accepted into the program, you can log in to your new account and get the HTML code to insert into your webpages.
Keep in mind that participation in AdSense requires you to have a website. If you don't have one, you can sign up for a free blog at www.blogger.com or create and publish useful, attractive webpages using Google Page Creator, at pages.google.com.
