Here is an excerpt of their product : "Our Keywords Logger script logs the keywords used at most major search engines when a user visits your site following a link from the search engine. By checking the referer we are able to extract the exact keywords used and store them in a database. The script also supports an API to display the keywords for a page as tags, and a tag-search feature so users can find other pages with similar content. Ultimately this helps improve your search engine visibility for these keywords as the more they're used, the more visible they are on your site." Here is the script in action http://communityseo.com/forums/The-X-Robots-Tag-t3327.html Question is , is it safe to implement this script on my site cuz I don't want to get my Adsense account banned. Thx
