If you want to attract more visitors to your webpage, you can invest some money in AdWords. Here are some usefull facts what AdWords is and how AdWords works. (the source is wikipedia as well)
AdWords is Google's flagship advertising product, and main source of revenue. AdWords offers pay-per-click (PPC) advertising, and site-targeted advertising for both text and banner ads. The AdWords program includes local, national, and international distribution. Google's text advertisements are short, consisting of one title line and two content text lines. Image ads can be one of several different Interactive Advertising Bureau (IAB) standard sizes.
Pay-Per-Click advertisements (PPC)
Advertisers specify the words that should trigger their ads and the maximum amount they are willing to pay per click. When a user searches Google's search engine on www.google.com, ads for relevant words are shown as "sponsored link" on the right side of the screen, and sometimes above the main search results.
The ordering of the paid listings depends on other advertisers' bids (thus the system is classified as P4P) and the "quality score" of all ads shown for a given search. The quality score is calculated by historical click-through rates and the relevance of an advertiser's ad text, keyword, and landing page to the search, as determined by Google.
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.
The "content network" shows AdWords ads on sites that are not search engines. Google automatically determines the subject of the pages and displays ads for which the advertiser has specified an interest in that subject. The ads show in boxes resembling banner ads, with the designation "Ads By Gooooooooooogle." These content network sites are those that use AdSense, the other side of the Google advertising model. Click through rates on the content network are typically much lower than those on the search network and are therefore ignored when calculating an advertiser's quality score.
Ad blocking and Adwords
Search
The ads are displayed on the top or right hand side of the natural search results. The ads are pure text, and thus difficult to block for normal ad-blocking software. However, the Mozilla Firefox extension CustomizeGoogle can remove them.
Content network
Advertisements on content websites are displayed via JavaScript-generated iframes and can be easily blocked, either by turning off JavaScript or using ad-blocking software such as Adblock.
Proxies
The search proxy Scroogle allows users to perform Google searches without receiving Google advertisements.
