Adsense the present day craze among the webmasters is basically an extra code that does wonders for your web site and can greatly help you with search engine optimization.  You can customize your own site with color schemes, placements and other ad formats. 

The search engines however are very sensitive to your playing deception with them.  They do not like false clicking on your own ads.  Hence if you have accidentally caused such clicking, you should immediately inform the search engine about such accidental clicking. 

You can also use the adblock extension of the Google search engine to convert the italic letters to normal and it will be easier for the viewers to read them.  You should also get rid of the browser cookies since they can cause strange things to happen at times when they get corrupted. This is one of the most important aspects of your search engine optimization campaign. 

Sometimes you may not be satisfied with the ads that are appearing.  In such case you can remove the code or modify it.  You can use adsense for searching and it can give you good results in finding out content based ads for your web site.  The primary task of adsense is to provide context relevant ads and this can be done also with the Google ad scheduling features.
