Reputation Management with SideWiki from Google
Did you know that Google now lets you write comments on ANY web page on the internet using the Google Toolbar or this bookmarklet? This has proved to be a controversial feature as it arguably gives Google partial control over your website. Here’s how to add a special entry as the website owner that will display above all others.
Google allows the owner of a website to write a special SideWiki entry on every page of their site. This entry will appear highlighted above other SideWiki comments. You can’t moderate or delete SideWiki comments left by other users but at least you can have your say.
You must first add your site to Google Webmaster Tools to prove ownership to Google SideWiki. Then you can write a comment on your own site.
