AdWords features

IP address exclusion

In addition to controlling ad placements through methods such as location and language targeting, ad targeting can be refined with Internet Protocol (IP) address exclusion. This feature enables advertisers to specify IP address ranges where they don't want their ads to appear.

Up to 100 IP addresses, or ranges of addresses, can be excluded per campaign. All ads in the campaign are prevented from showing for users with the IP addresses specified.

Location-based exclusion is also offered as a method of narrowing targeted users.^[5]

Frequency capping

Frequency capping limits the number of times ads appear to the same unique user on the Google Content Network. It doesn't apply to the Search Network. If frequency capping is enabled for a campaign, a limit must be specified as to the number of impressions allowed per day, week, or month for an individual user. The cap can be configured to apply to each ad, ad group, or campaign.^[6]

[edit]Placement-targeted advertisements (formerly Site-Targeted Advertisements)

In 2003 Google introduced site-targeted advertising. Using the AdWords control panel, advertisers can enter keywords, domain names, topics, and demographic targeting preferences, and Google places the ads on what they see as relevant sites within their content network. If domain names are targeted, Google also provides a list of related sites for placement. Advertisers may bid on a cost-per-impression (CPM) orcost-per-click (CPC) basis for site targeting.^[7]

With placement targeting, it is possible for an ad to take up the entire ad block rather than have the ad block split into 2 to 4 ads, resulting in higher visibility for the advertiser.

The minimum cost-per-thousand impressions bid for placement-targeted campaigns is 25 cents. There is no minimum CPC bid, however.

[edit]AdWords distribution

All AdWords ads are eligible to be shown on www.google.com. Advertisers also have the option of enabling their ads to show on Google's partner networks. The "search network" includes AOL search, Ask.com, and Netscape. Like www.google.com, these search engines show AdWords ads in response to user searches, but do not affect quality score.

The "Google Display Network" (formerly referred to as the "content network") shows AdWords ads on sites that are not search engines. These content network sites are those that use AdSense and DoubleClick, the other side of the Google advertising model. AdSense is used by website owners who wish to make money by displaying ads on their websites. Click through rates on the display network are typically much lower than those on the search network and are therefore ignored when calculating an advertiser's quality score.

Google automatically determines the subject of pages and displays relevant ads based on the advertisers' keyword lists. AdSense publishers may select channels to help direct Google's ad placements on their pages, to increase performance of their ad units. There are many different types of ads that can run across Google's network, including text ads, image ads (banner ads), mobile text ads, and in-page video ads.

Google AdWords' main competitors are Yahoo! Search Marketing and Microsoft adCenter.

In 2010, Yahoo formed a partnership with Microsoft, giving Microsoft the control over powering the Yahoo search marketing ads. Both accounts are now run through Microsoft AdCenter. When ads are displayed on Yahoo now, it is powered by Microsoft AdCenter and is run through the Microsoft software interface.

[edit]AdWords account management

To help clients with the complexity of building and managing AdWords accounts search engine marketing agencies and consultants offer account management as a business service. This has allowed organizations without advertising expertise to reach a global, online audience. Google has started the Google Advertising Professionals program to certify agencies and consultants who have met specific qualifications and passed an exam.^[8] Google also provides account management software, called AdWords Editor.

Correct choice of keywords is very important because the targeting of ads by Google is totally dependent upon the keyword selection. Keyword choice is also a very large factor in determining the level of exposure the Google ad receives, and to a large extent, who sees the ad.

Another useful feature is the My Client Center available to Google Professionals (even if not yet passed the exam or budget parameters) whereby a Google professional has access and a dashboard summary of several accounts and can move between those accounts without logging in to each account.

The Google Adwords Keyword Tool provides a list of related keywords for a specific website or keyword.^[9]

[edit]Google Click-to-Call

Google Click-to-Call was a service provided by Google which allows users to call advertisers from Google search results pages. Users enter their phone number, Google calls them back and connects to the advertiser. Calling charges are paid by Google. It was discontinued in 2007.^[10] For some time similar click-to-call functionality was available for results in Google Maps. In the Froyo release of Google's Android operating system, in certain advertisements, there is a very similar functionality, where a user can easily call an advertiser.
