PPC is one of the four basic types of Search EngineMarketing. PPC is also one of the most cost-effective ways of targeted internet advertising. According to Forbes magazine, PPC or Pay Per Click, accounts to 10 billion dollars a year, was around 8 billion in 2008 and is expected to increase to around 14 billion dollars by the year 2010.

Let us take a quick look at how PPC Search Engines work.

These engines create listings and rate them based on a bid amount the webmaster is willing to pay for each click from that search engine. Advertisers bid against each other to receive higher ranking for a specific keyword or phrase.

The highest bidder for a certain keyword or phrase will then have the site ranked as number 1 in the PPC Search Engines followed by the second and third highest bidder, up to the last number that have placed a bid on the same keyword or phrase. Your ads then will appear prominently on the results pages based on the dollar amount bid you will agree to pay per click.

How do you make money by using PPC into your affiliate marketing business?

Most affiliate programs only pay when a sale is made or a lead delivered after a visitor has click-through your site. Your earnings will not always be the same as they will be dependent on the web site content and the traffic market.

The reason why you should incorporate PPC into your affiliate marketing strategy is that earnings are easier to make than in any other kind of affiliate program not using PPC. This way, you will be making profit based from the click-throughs that your visitor will make on the advertisers site. Unlike some programs, you are not paid per sale or action.

PPC can be very resourceful of your website. With PPC Search Engines incorporated into your affiliate program, you will be able to profit from the visitors who are not interested in your products or services. The same ones who leave your site and never comes back.

You will not only get commissions not only from those who are just searching the web and finding the products and services that they wanted, but you will be able to build your sites recognition as a valuable resource. The visitors who have found what they needed from yor site are likely to come back and review what you are offering more closely. Then they will eventually come back to search the web for other products.

This kind of affiliate program is also an easy way for you to generate some more additional revenues. For example, when a visitor on your site does a search in the PPC Search Engine and clicks on the advertiser bidded listings, the advertisers account will then be deducted because of that click. With this, you will be compensated 30% to 80% of the advertisers bid amount.

PPC is not only a source of generating easy profits; it can also help you advertise your own site. Most of the programs allow the commissions received to be spent for advertising with them instantly and with no minimum earning requirement. This is one of the more effective ways to exchange your raw visitors for targeted surfers who has more tendencies to purchase your products and services.

What will happen if you when you integrate PPC into your affiliate program?

PPC usually have ready-to-use affiliate tools that can be easily integrated into your site. The most common tools are search boxes, banners, text links and some 404-error pages. Most search engines utilize custom solutions and can provide you with a white-label affiliate program. This enables you, using only a few lines of code, to integrate remotely-hosted co-branded search engine into your website.

The key benefits? Not only more money generated but also some extra money on the side. Plus a lifetime commissions once you have referred some webmaster friends to the engine.

Keyword density is an indicator of the number of times the selected keyword appears in the web page. But pay attention, keywords shouldnt be over used, they should be just sufficient enough to appear at important places.

If you repeat your keywords with every other word on every line, then your site will probably be rejected as an artificial site or spam site.

Keyword density is always expressed as a percentage of the total word content on a given web page.

Suppose you have 100 words on your webpage (not including HMTL code used for writing the web page), and you use a certain keyword for five times in the content. The keyword density on that page is got by simply dividing the total number of keywords, by the total number of words that appear on your web page. So here it is 5 divided by 100 = .05. Because keyword density is a percentage of the total word count on the page, multiply the above by 100, that is 0.05 x 100 = 5%

The accepted standard for a keyword density is between 3% and 5%, to get recognized by the search engines and you should never exceed it.

Remember, that this rule applies to every page on your website. It also applies to not just to one keyword but also a set of keywords that relates to a different product or service. The keyword density should always be between 3% and 5%.

Simple steps to check the density:

Copy and paste the content from an individual web page into a word-processing software program like Word or Word Perfect.

Go to the Edit menu and click Select All. Now go to the Tools menu and select Word Count. Write down the total number of words in the page.

Now select the Find function on the Edit menu. Go to the Replace tab and type in the keyword you want to find. Replace that word with the same word, so you dont change the text.

When you complete the replace function, the system will provide a count of the words you replaced. That gives the number of times you have used the keyword in that page.

Using the total word count for the page and the total number of keywords you can now calculate the keyword density.

All you need now is little something that actually tells you what the absolute best and most profitable keywords to use are. And yes, that tool does exist! Not only does it tell you what the most profitable keywords you need to be using, it tells you:

* If an Adwords advertiser is a clickbank, paydotcom, or amazon affiliate

* See any Adwords advertiser’s daily Adwords spending, clicks per day, cost per click

It does alot more too!
