In the time after Google Adword first opened up shop and people started flocking to the pay per click advertising has developed into the most popular way to advertise on the internet. An advertiser can create an advertisement and the search engine will take over and do the remainder of the work. That is a deal that a great many advertisers have been unable to turn down.

In theory the relationship between search engine and advertiser is a symbiotic one. The advertiser writes an advertisement, then pays a search engine to do the work in identifying potential customers for them through the use of keyword identification.

When web surfers put a search term into the browsers search box the search engine displays the advertisers ads at the same time as the search results are displayed.

The reality however, is a bit more difficult than that.

The practice of choosing a keyword can be complicated. It often is not enough to simply access the tracking tools available through the search engine. Each of the keywords listed there are used frequently and therefore are going to turn up pages upon pages of results.

Because the basic web searcher's interest isn't going to be sustained past the 5 or 10 pages, the advertiser wants his ad to be shown on the first 5 or so pages to stand a better chance of seeing a profit.

Here is where things get a bit difficult. The ads that are shown with the top search results are put their because the advertiser is willing to bid more money "per click" than other advertisers.

The standard form of advertising allowed the advertisers to have an ad displayed for a set amount of time for an established fee, regardless of how many people saw it. Advertisers realized this was an inefficient way to get customers.

This brought about pay-per-click advertising. In this form of advertising an advertiser only paid a fee when his ad was chosen. That way they could make a better profit if their ad was chosen on a regular basis.

After the initiation the idea came to be sure that the ads having the highest price per click are shown along with the highest search results so that the search engine would realize the greatest profits possible. This brought competition into play in setting the bid prices. Advertisers would try to outbid the competitors.

The expenses for a pay per click ad campaign can compound rapidly without the advertiser even realizing what is going on because when your advertisement is in one of the first ad spots on a search results page it can get a lot of unprofitable interest and very little paying customers. That is wasted advertising budget.

Pay-per-click advertisement has potential to be a perilous obstacle course for an unaware advertiser to make his way through; it is a more complex enterprise than many marketers say it is. The good thing is that there are some great resources available (as well as other ways to advertise) out there on the internet for those sharp enough to use them.
