Once you join the AdSense program - and Google approves your site or sites, which we'll cover in detail shortly - the actual process of displaying ads on your website is extremely simple. You are provided with a small HTML script, which you can paste anywhere on your webpage. You may paste this code any number of times and on multiple pages, and watch the ads get served! Google automatically places AdWords ads that are most relevant, from its extensive advertiser base. Google employs various sophisticated algorithms to determine the relevancy of the ads to your content. Before we get into how Google assesses sites, and whether a few or many placements of that magic script will deliver optimum results, let's review the Advantages of AdSense.
Advantages of the Google AdSense system
Google AdSense is simple to use and manage. Once approved, displaying ads on your webpage does not take time and requires minimal technical knowledge. Google AdSense is very smart about ad selection. The ads that are displayed are only those that are relevant to your content, and Google has strict quality control on the general quality of the ads.
Google AdSense uses text-only ads. Far from being low-tech, text ads are more effective than flashy ads. The click through rate of text ads is proven to be higher than that of animated ads! More clicks equals more money, and text ads equals more clicks. Also…text ads are very "low weight" and very fast loading. The AdSense program will not slow your website, or your visitors, down. You can also Use graphic ads.
