What is PPC ?
Short for pay-per-click, an Internet marketing formula used to price online advertisements. In PPC programs the online advertisers will pay the Internet Publishers the agreed upon PPC rate, regardless if a sale is made or not. Also called cost-per-click (CPC).
Pay per click, or PPC, is an advertising technique used on websites, especially search engines. Pay per click advertisements are usually text ads placed near search results; when a site visitor clicks on the advertisement, the advertiser is charged a small amount. Variants include pay for placement and pay for ranking. Pay per click is also sometimes known as Cost per click or CPC.
Pay-per-click advertising, also known as PPC, is a form of online advertising whereby visitors are directed to an advertiser’s website after clicking on an advertisement, and the advertiser pays for each visitor on a per-click basis.
Each click can be anywhere from 1 pence to several pounds in cost, depending on many factors, including the pay-per-click search engine being used to advertise on, and the search phrase that is being targeted.
Perhaps the best example of pay-per-click advertising is Google’s PPC advertising called Google AdWords. In the screengrab of a Google search results page below, the PPC results have a red box around them.
Google Adwords, in a nutshell, works like this; when a Google search engine user types in an applicable search phrase for your business and you are bidding on that search phrase your text ad has a chance to be displayed. You are only charged when the search engine user clicks on your text ad, hence the name pay-per-click.
Successful PPC is made up of these main factors:
1. Bidding on a sufficiently large number of relevant search phrases.
2. Bidding enough for each search phrase so that your text ad appears where it will be seen (for brand awareness) and clicked (to send the search engine user to your web site).
3. Constructing the campaign so it is very targeted.
4. Providing very relevant information for the searchers who click on your text ads.
5. Careful measurement and testing of results.
So these are the major problems web site owners face; how do I come up with 1000s to 10000s of search phrases, how much should I bid for each search phrase, how do I construct a really targeted campaign, how do I provide really relevant information for the searchers and how do I measure and test the whole thing?

What is PPC advertising?
In the last few weeks, we’ve been going through a lot of the mechanics behind pay-per-click (PPC) advertising. Today we’re going to step back and talk about PPC advertising in general and where the LookSmart AdCenter fits into the landscape of PPC providers.
PPC Advertising 101
First of all, what is “PPC” advertising? The PPC stands for “pay-per-click”. You pay LookSmart a certain amount every time a user clicks on an advertisement that we display on one of our partners’ web sites. You tell LookSmart the maximum amount you’re willing to pay for each of these clicks, and LookSmart compares your bids to other advertisers’ bids to determine which ads to show and in what order.
PPC advertising is very different from other forms of online advertising. For example, some web sites will let you place an advertisement by paying a published CPM (cost-per-thousand) rate. This means that you’ll pay a certain fee every time your ad is shown, regardless of whether it is clicked on.
Still other sites may charge you a fixed monthly or quarterly subscription fee. This is especially popular with online directories. Your costs are the same every month but the price is set by the service provider.
PPC Advantages
PPC advertising has several advantages over other forms of online advertising, including:
- You choose your price. You decide what your maximum PPC price is for your ads. For search advertising, you can choose a different price for every keyword you bid on. Clever advertisers find ways to optimize their bids to keep their costs low.
- You choose your keywords. With PPC advertising, you can be very specific about where you want your ads to show. You have total control over your keywords at all times and can make changes on a daily basis. This can be very flexible and responsive to your needs.
- You pay only for success. You pay only when one of your future visitors clicks on your ads. This means that you have the opportunity to convert your visitors to paying customers with each click. Other forms of advertising make you pay even if the visitor never actually makes it to your site.
What is the LookSmart AdCenter?
The LookSmart AdCenter is the web site where you go to place your ads on the LookSmart ad network. LookSmart has partnered with leading search sites such as CNET’s Search.com and others to provide you with a low-cost source of visitors to your web site.
When you buy advertising with LookSmart, your ads can appear on LookSmart’s web sites like FindArticles or other sites on our network. LookSmart licenses its ad serving technology to other companies, so your ads can appear on any number of quality sites.
LookSmart also employs quality controls on its network to help keep your costs low and your advertising campaigns productive. LookSmart looks at clicks advertisers receive from our partners and evaluates them for their cost effectiveness.
What is CPC ?
Short for cost-per-click, an Internet marketing formula used to price online advertisements. Advertisers will pay Internet publishers based on the number of clicks a specific ad gets.

CPC Advertising“Cpc advertising” is becoming quite popular in the business world, especially for businesses who have acquired a web site or links leading to their company information.
So what does it take to choose and produce successful “cpc advertising” and can you do it on your own? Well, let me begin by saying that cpc advertising is something that can be created on your own behalf but, if you are not savvy with the internet, keywords, ranking, placement, and rates, then you might want to join up with a professional. “Cpc advertising” isn’t as simple as writing a few lines of text and having it published in the local newspaper or in one of those free ad booklets. It takes a lot of research, creativity, comparisons, and patience. For your cost-per-click ad to be successful it must be genuine and relative to whichever product or service your business is promoting. CPC Advertising ResearchResearch consists of determining what keywords and phrases are being utilized by your competitors as well as whom they are joining forces with in order to produce productive ads. Creativity consists of building a strong list of AdWords and phrases that will allow consumers to find your business within a few clicks of the mouse as well as designing a suitable banner and lead page for your customer’s connection. Comparisons need to be performed in order for you to know what prices are being charged for products or services resembling your offerings. And, most importantly, patience is needed in order to detect whether or not your “cpc advertising” is working. This form of advertising cannot be created and put into production in a minute or two. Creating great “cpc advertising” can take weeks or months before it is considered sufficient enough to receive affordable rates and eventful enough to draw in consumers who are ready to make a purchase. Another quality needed to gain profits from “cpc advertising” is to be open to change. There may be certain keywords or phrases that you feel you should dedicate to your products but they can cost you high cost-per-click rates. When this happens you have to be prepared to choose keywords and phrases that you, and your business, can afford. Cpc advertising can get expensive. If you have to choose between bidding high on one or two, guaranteed to place, keywords or bid lower on many pertinent keywords, choose the latter. It will be financially intelligent on your part if you have a vast list of AdWords compared to access to just a few. |
CPC can stand for two things; Cost Per Click (also known as Pay Per Click) or Cost Per Call, a new way advertising online. Here we will discuss Cost Per Call as new way to attract customers without needing to use a website. For more information on Cost Per Click please read our pay per click services page.
CPC: Cost Per Call
One of the biggest problems with traditional online advertising, such as Pay Per Click, is that businesses require a website to allow people to contact them. Not only that a bad website can have a negative impact and turn people away, resulting in a waste of online advertising budget.
Cost Per Call works by allowing ANYONE to attract new businesses using a traditional medium… phone calls! Users search for their product or services in the usual way by typing keywords into search engines. This time, instead of clicking on adverts and going to websites, searchers are presented with a page of information about the company and a phone number to call. When the searcher calls the number, it is logged by the phone and search engine provider and is connected to the company.
A simple, but very effective, concept which can work for any business.
How your business can benefit from Cost Per Call advertising
The benefits of cost per call marketing are numerous;
- Improve your sales
Sometimes web users are not happy dealing with businesses over the Internet and would rather contact them directly using a phone. This increases the chance of making a sale as product offerings and questions can be answered directly. - Increase advertising effectiveness
In traditional online advertising, tracking phone calls as a result of your online advertising has been notoriously difficult. If someone clicks on your Google advert, for example, someone may be interested in your product but call you either directly, or weeks, possibly months later, which makes tracking enquiries difficult. With cost per click, this problem is removed. - Reduce marketing fraud
Pay per click (or cost per click) marketing has been prone to click fraud over the last few years and this was even highlighted when Google floated on the stock exchange. With cost per call, the chances of fraud are significantly lower as searchers have to pick up the phone to make the connection with the advertiser. This process is significantly harder to automate and means that your budget should be protected.
Cost per call (also called Pay Per Call) has only just started on the main search engines and directories so advertising using this method is difficult as the technology is still in it’s infancy although it has been in use in the USA since early 2005. However, the benefits are there for all to see, so expect cost per call advertising to be the biggest growth areas in online marketing during 2006.
Who to contact
As discussed, cost per call is still very new, although the concept is easy to relate to. Many of the big search engines and directories, such as Google, Findwhat.com, Yahoo, AOL and Thompson will start rolling out Cost Per Call (CPC) advertising throughout 2006 so check back to our website regularly to find out the last CPC news.
Google tests pay per call ads
Don’t call us, we’ll call you
Google has begun testing pay-per-phone-call ads, an emerging online advertising model that is a twist on the popular pay-per-click ads.
While pay-per-click ads link users with advertisers’ websites, pay-per-phone call ads link users and advertisers by phone. The Kelsey Group recently forecasted that in 2009 spending on this type of online ad could reach $1.4bn, so it’s not surprising to see Google testing this model.
Just as pay-per-click advertisers only pay when a user clicks over to their website, in pay-per-phone call advertisers only pay when the ad leads a user to contact them by phone.
As in pay-per-click, the cost of pay-per-call ads typically is determined via an auction process. The larger an advertiser’s bid for a search keyword or search category, the higher its ad appears on the list of related ads that a search engine serves up after a user enters a search query.
In Google’s case, a phone icon has begun to appear with some ads and after users click on it, they can enter their phone number. Google then generates a call between the user and the advertiser, according to an FAQ page about the pilot program on Google’s website.
The call is free to the Google users.
“Google is always considering new ways to provide value to its advertisers and we frequently run tests of potential new features and products. We are currently conducting a limited test of a pay-per-call model, but we don’t have any additional information to share at this time,” a Google spokesman wrote in an email message to IDG News Service.
For users concerned about giving out their phone numbers, Google promises not to share the number with anyone, including the advertisers. “When you’re connected with the advertiser, your number is blocked so the advertiser can’t see it. In addition, we’ll delete the number from our servers after a short period of time,” the FAQ reads.
Ingenio.com is considered the leader in this emerging market - they sell pay-per-phone-call ads to advertisers and provide the back-end technology for the ads. Its pay-per-phone call ads are distributed via a network of providers that includes AOL. AOL shows Ingenio ads in the sponsored search section of its search engine results and its AOL Yellow Pages online directory.
Yahoo has also been testing pay-per-phone-call ads for several months on a small portion of its search traffic, a Yahoo spokeswoman said Monday. There is no ending date for the test, she said. “If it’s something our advertisers want, we’ll have more to say at a later date,” she said.
Another big player in this market is Verizon Communications, which began offering pay-per-phone-call ads in October.
An acknowledgement from search giants Google and Yahoo that they are dipping their toes into pay-per-call is significant news for this online ad model, said Greg Sterling, a Kelsey Group analyst. It is also good news for companies that prefer to generate calls, instead of website clicks, from their online ads, Sterling said.
For Google, if it were to fully embrace pay-per-call, the benefits would include getting a higher revenue rate than from pay-per-click, because pay-per-call ads in general tend to be more expensive, he said. They typically start at around $2 (£1)per call, with an average of $7 (£4), and can cost more than $30 (£18), Sterling said.
The reason why advertisers are generally willing to pay more for a call than for a click is that a prospective client who calls is presumably closer to making a buying decision than one who visits a website, he said.
Also, a company that gets a phone lead can tailor its message and sales pitch on a one-on-one basis and engage the potential client in a conversation, a much deeper level of engagement than is generally possible with a website visitor, he said.
Google would also attract a broader base of advertisers, namely those that haven’t found pay-per-click particularly effective, he said.
Pay-per-call is an ideal model in situations in which products for sale are costly, or where closing the sale involves a complex process, he said. Pay-per-call is also ideal for providers of professional services, such as doctors, lawyers, accountants and financial planners, Sterling said.

Choosing CPC
When establishing a Pay Per Click campaign you want to budget to minimize initial cash investment while maximizing your sales. You set what?s known as a max bid?the maximum amount of money you are willing to pay for a clickthrough within a certain category. You?ll never have to pay more than your max bid for a clickthrough.
Many Pay Per Click campaigns offer a feature called auto bid. This means that if you outbid your nearest competitor for placement, you?ll only be charged $0.01 more than your competitor?s maximum bid. For instance, you and a competitor are competing for traffic relevant to air conditioners in Dallas, Texas. Your max bid is $2.25, and your competitor?s bid is $1.50?you will ?win? the bid and receive higher placement for only $1.51 for each clickthrough.
What is Internet Marketing ?
A global network connecting millions of computers. More than 100 countries are linked into exchanges of data, news and opinions.
Unlike online services, which are centrally controlled, the Internet is decentralized by design. Each Internet computer, called a host, is independent. Its operators can choose which Internet services to use and which local services to make available to the global Internet community. Remarkably, this anarchy by design works exceedingly well.
There are a variety of ways to access the Internet. Most online services, such as America Online, offer access to some Internet services. It is also possible to gain access through a commercial Internet Service Provider (ISP).
Pay per click
From Wikipedia, the free encyclopedia
Pay per click (PPC) is an Internet advertising model used on search engines, advertising networks, and content websites, such as blogs, where advertisers only pay when a user actually clicks on an advertisement to visit the advertisers’ website. With search engines, advertisers typically bid on keyword phrases relevant to their target market. When a user types a keyword query matching an advertiser’s keyword list, or views a webpage with relevant content, the advertisements may be displayed. Such advertisements are called sponsored links or sponsored ads, and appear adjacent to or above the “natural” or organic results on search engine results pages, or anywhere a webmaster or blogger chooses on a content page. Content websites commonly charge a fixed price for a click rather than use a bidding mechanism.
Although many PPC providers exist, Google AdWords, Yahoo! Search Marketing, and Microsoft adCenter are the largest network operators as of 2007. Minimum prices per click, often referred to as costs per click (CPC), vary depending on the search engine and the level of competition for a particular phrase or keyword list—with some CPCs as low as US$0.01. Very popular search terms can cost much more on popular search engines. The PPC advertising model is open to abuse through click fraud, although Google and other search engines have implemented automated systems to guard against abusive clicks by competitors or corrupt webmasters.[1]
Contents[hide] |
Categories
Pay per click campaigns can be categorized into two major categories: sponsored match (or keyword) and content match. Sponsored match campaigns involve the display of advertisements on search engine results pages, whereas content match campaigns involve the display of advertisements on publisher websites, newsletters, and e-mails.[2]
There are other types of pay per click programs that target product or service searches and product comparison sites. Search engine companies may participate in more than one category. PPC programs do not generate any revenue solely from Web traffic for websites that display the advertisements: Revenue is generated only when a user clicks on the advertisement itself.
Keyword-based PPC
Keyword-based pay per click advertisers bid on search terms—keywords consisting of words or phrases, and possibly product model numbers. When a user searches for a particular keyword, the list of advertiser links appears, where the ordering of those links is based on the amount bid for the given keyword. Keywords are the very heart of PPC advertising, and are guarded as highly-valued trade secrets by the advertisers. Many advertising firms offer software or services to help advertisers develop keyword strategies. Content Match, a service offered by Yahoo!, distributes the keyword ad to the search engine’s partner sites and/or publishers that have distribution agreements with the search engine company.
As of 2007, the following are notable PPC keyword search engines:
- Ask.com
- Baidu
- Google AdWords
- LookSmart
- Microsoft adCenter
- MIVA
- Superpages.com
- Yahoo! Search Marketing
- Yandex
- Clicksor
Product engines
Product engines (a.k.a. product comparison engines or price comparison engines) are search engines for products, and let advertisers provide “feeds” of their product databases. When a user searches for a product, links to advertisers are displayed for that particular product. More prominence is given to advertisers who pay more; however, the user can typically sort by price.
Some product engines such as Shopping.com use a pay per click model and have a defined rate card.[3] Other engines such as Google Product Search, part of Google Base (previously known as Froogle), do not charge for the listing, but still require an active product feed to function.[4]
The following are notable PPC product engines:
Service engines
Service engines allow advertisers to provide feeds of their service databases. When a user searches for a service, links to advertisers are displayed for that particular service. More prominence is given to advertisers who pay more; however, the user can typically sort by price or other criteria. Some pay per click product engines have expanded into the service space, while other service engines operate in specific vertical markets.
The following are notable PPC service engines:
Pay per call
Pay-per-call is a business model for advertisement listings in search engines and directories that allows publishers to charge local advertisers on a per-telephone-call basis for each sales lead (i.e., call) the publishers generate. The term “pay per call” is sometimes confused with click-to-call, which along with call tracking, is a technology that enables the pay-per-call business model. Pay per call is not restricted only to local advertisers: Many of the pay per call search engines allow advertisers with a national presence to create advertisements with local telephone numbers. According to the Kelsey Group, the pay per call market is expected to reach US$3.7 billion by 2010.[5]
Pay per delivery
Pay per delivery is a variation on pay per click used in e-mail marketing. E-mail marketing campaigns are charged only on the basis of e-mails that are delivered successfully.
Pay per action
Pay per action (PPA) is a variation on pay per click adopted by many search engines. An advertiser pays a specified amount upon successful completion of some action (e.g., conversion, sales lead, or sale). PPA was a beta test for advertising distribution within the Google Content Network. However, Google announced in July 2008 that the program will be discontinued in August 2008.
History
In February 1998 Jeffrey Brewer of Goto.com, a 25-employee startup company (later Overture, now part of Yahoo!), presented a pay per click search engine proof-of-concept to the TED8 conference in California.[6] This presentation and the events that followed created the PPC advertising system. Credit for the concept of the PPC model is generally given to Idealab and Goto.com founder, Bill Gross.
Google started search engine advertising in December 1999. It was not until October 2000 before the AdWords system was introduced, allowing advertisers to create text ads for placement on the Google search engine. However, PPC was only introduced in 2002; until then, advertisements were charged at cost-per-thousand impressions. Yahoo! advertisements have always been PPC-based since their introduction in 1998.
For a more in-depth presentation of PPC’s history, see Fain and Pedersen (2006).[7]
Use in “paid to surf” websites
Pay per click search engines enlist members, known as affiliates, to display webpages called portals, which display various keywords. PPC affiliates will advertise their portals to paid to read (PTR) websites, in the hopes that the PTR affiliates will click a keyword, and then click one of the results. The PPC affiliates receive a small commission for each search.
Owners of paid to surf websites may advertise their own search portals, sending more advertisements—and essentially more money—to their affiliates who click more keywords and search results. However, this process is frowned upon, as many consider these webmasters to be forcing their affiliates into committing click fraud, as the majority of the paid to surf website’s revenue may come from the webmasters’ PPC commissions.
