By knowing the most expensive keywords on the internet, you can create websites and web pages based on these keywords. On these sites and pages, you can serve expensive ads and/or promote affiliate offers that reap high bounties when clicked or completed.

The challenge lies in driving traffic to these sites. One way to drive traffic is through search engine optimization, whereby you create a website that ranks highly on the search engines and receive “free” traffic. Or, if you already have an existing well-ranked site, you can create new pages linked from your existing pages. A second way to drive traffic is through online advertising.

With regards to advertising, one key is to understand correlations between keywords. By determining correlations between inexpensive and expensive keywords, you can advertise on the inexpensive keyword (via pay-per-click (PPC) advertising on search engines) to drive traffic to your website that serves ads based on expensive keywords. For instance, advertising on the keyword “painting” ($0.20 keyword), and sending visitors to your site about the related topic “home remodeling” ($2.00 keyword) allows you to profit from the wide spread between the keyword prices of the two correlated keywords.

Likewise there are many opportunities to run banner and other ads through online advertising networks to drive traffic to your website. These ads can run on both “painting” and “home remodeling” websites. The cost of CPM (cost per impression) advertising typically does not reflect the price of the keywords. That is, a banner ad on a “painting” website typically costs the same as a banner ad on a “home remodeling” website. This sharply contrasts the price of PPC advertising on search engines which vary widely based on the keyword.

There are two other ways to profit from knowing the most expensive keywords. The first doesn’t even require you to own or operate a website. In this method, you advertise using inexpensive means (e.g., via pay-per-click advertising on inexpensive keywords or CPM advertising) and direct traffic to high paying affiliate offers. The second method is to set up your own search engine. There are several companies that allow you to easily set up a search engine that serves PPC ads syndicated from Google, Overture or other PPC search engine networks. Once you create your engine, you can drive traffic directly to your PPC results, and get paid every time someone clicks on one of the results. Likewise, on your search engine’s home page, you can include many links to expensive keywords, so that when someone clicks on it, the engine shows expensive ads based on those keywords.

Understanding keyword pricing is critical to the online advertising, PPC search engine and affiliate marketing businesses – businesses that combine for over $25 billion a year in revenues. With a market of this size, generating substantial profits, if you have the right information, is really not that challenging.
