One of the great new features of Google Analytics is the ability to get the Referral Paths for a Referring Site. You can do this by going to 'Traffic Sources > Referring Sites' and then click on one of the sites listed. The first thing that you will notice if you do this is that it is just the Request URI from the Referring Site with no domain or query parameters. If the site is a dynamic site then there is no way to see exactly where the visit came from. I have come up with a solution for this problem.

 "rel=nofollow" is not a recognised attribute for the <iframe> tag according to W3C specs.
 
 Use some javascript and document.write to place the iframe code on the page. You'll still need to make sure that the url is recognised as being a url, so I'd suggest first passing the html through the javascript escape() function, then copying and pasting that into the javascript code:
 
 <script type="text/javascript">
document.write( unescape('your%20escaped%20html%20code') );
</script>

 I have often wondered how often Google Analytics updates and I set out to find that out today. One thing you need to keep in mind, regardless of how often it updates or refreshes, is that the best time to view your stats is the next day. You will notice that if you check your stats at 2-3 am it will account for every hour, but when you view the stats at around noon, the actual number of visits and keywords used to reach your site has risen.

If you have a blog or a content site, now you can generate revenue from the effort that you make to publish your work.

Google has a program named AdSense that lets you generate revenue by placing relevant text advertising in your site pages.

This site has been making significant revenue by placing Google AdSense ads. You can do the same even if your site has low traffic or even if the site content is not in English.
